Description

Method for determining transmission parameters and wireless device

Technical Field

The present application relates to the field of communications technologies, and more particularly, to a method and a wireless device for determining transmission parameters.

Background

With the development of mobile communication, WIreless-Fidelity (WiFi) technology has been widely adopted in terminal devices. On one hand, existing wireless devices (e.g., wiFi products) have been uniformly provisioned with transmit power specifications at the time of shipment. On the other hand, in order to ensure the quality of the transmitted signal, the straight-through rate of the production line, and the like, in consideration of errors in the calibration of the production line, there is a certain power margin, for example, a power margin of about 2 decibels (dB), according to the transmitted power specification, and the influence of the difference of the 2dB transmitted power on the coverage radius can reach 26%.

Then, how can the maximum coverage capability of the wireless device (e.g., wiFi product) be exploited as much as possible under the current increasingly high WiFi signal strength requirements, coverage requirements, throughput requirements, etc.?

Disclosure of Invention

The application provides a method for determining transmission parameters and wireless equipment, which can exert the maximum coverage capability of the wireless equipment and ensure the communication performance.

In a first aspect, a method for determining a transmission parameter is provided, where the method may be performed by a network device, or may be performed by a chip configured in the network device, and this application is not limited thereto.

Specifically, the method comprises the following steps: the method includes the steps that a first wireless device determines a transmission parameter corresponding to a first rate, wherein the transmission parameter includes a target transmission power or a first transmission power, and the target transmission power or the first transmission power is greater than a preset transmission power, wherein the target transmission power is a maximum transmission power corresponding to the first rate, the first transmission power is a transmission power used by a second wireless device at the first rate, the preset transmission power is a power specification designed for the first rate in advance, and the first rate is a rate currently used by the second wireless device; at the first rate, the first wireless device communicates with the second wireless device based on the transmission parameters.

The first wireless device may be a network device, and the second wireless device may be a terminal device.

The preset transmission power, which may also be referred to as a preset transmission power specification, represents a predefined original transmission power specification. The target transmit power, which may also be referred to as a target transmit power specification, represents a maximum transmit power at a first rate. The first transmission power is used by the second wireless device at a first rate, and the transmission power is greater than a preset transmission power, or the transmission power is greater than or equal to a target transmission power.

The first rate is a currently used rate, and the currently used rate may be a maximum rate that can be supported by the second wireless device, or may be any rate, which is not limited in this application.

Wherein the first wireless device communicates with the second wireless device based on the target transmit power specification, e.g., the second network device communicates traffic within a network coverage of the first wireless device.

Based on the above technical solution, in the rate negotiation process, the specification of the set transmission power (for example, referred to as a target transmission power) is greater than the preset transmission power specification, or the transmission power (for example, referred to as a first transmission power) selectable at the first rate is greater than the preset transmission power specification, so that the situation that the actual maximum capabilities of the production line output boards are different as much as possible can be considered, the maximum coverage capability of the wireless device (for example, referred to as a first wireless device, for example, a WIFi product) is exerted as much as possible, and the coverage range is improved. It should be understood that the transmit power at which the first wireless device and the second wireless device communicate is not necessarily the target transmit power or the first transmit power, e.g., the transmit power at which the first wireless device and the second wireless device communicate may be less than or equal to the target transmit power.

With reference to the first aspect, in certain implementations of the first aspect, the target transmit power or the first transmit power is less than or equal to a first value, and the first value is calculated based on the preset transmit power and a preset power margin.

Based on the technical scheme, the purpose of exerting the maximum coverage capability of the first wireless equipment (such as a WIFi product) as much as possible is achieved by reasonably using the power margin. Wherein the power margin represents a power margin reserved for improving production uniformity power fluctuation.

With reference to the first aspect, in certain implementations of the first aspect, a first period of time during which the first wireless device communicates with the second wireless device based on the first transmit power; the method further comprises the following steps: the first wireless device determines the transmission power of the first wireless device and the second wireless device in the second time period according to the communication quality, wherein the communication quality is the communication quality when the first wireless device communicates with the second wireless device based on the first transmission power in the first time period.

The first time interval is any time interval, and the starting time of the second time interval is positioned after the starting time of the first time interval.

Based on the above technical solution, after determining the transmission parameter (e.g. the target transmission power or the first transmission power), the transmission power of the first wireless device and the second wireless device during communication at the first rate in the second period may be determined by judging the current (e.g. noted as the first period) communication quality, so that the transmission power specification may be improved and the communication performance may be ensured.

With reference to the first aspect, in certain implementations of the first aspect, the determining, by the first wireless device, a transmit power at which the first wireless device communicates with the second wireless device for the second period according to a communication quality includes: when the communication quality meets a preset first condition, in the second period, the transmission power of the communication between the first wireless device and the second wireless device is a second transmission power, and the second transmission power is greater than or equal to the first transmission power.

Based on the above technical solution, after determining a good transmission parameter (e.g. a target transmission power or a first transmission power), if the current communication quality (e.g. referred to as a first time interval) satisfies a certain condition (e.g. referred to as a preset first condition), in a second time interval, at a first rate, the transmission power (e.g. referred to as a second transmission power) of the first wireless device and the second wireless device during communication may be greater than or equal to the original transmission power (e.g. referred to as a first transmission power).

With reference to the first aspect, in certain implementations of the first aspect, the determining, by the first wireless device, a transmit power at which the first wireless device communicates with the second wireless device for the second period of time according to the communication quality includes: when the communication quality does not meet a preset first condition, in the second time interval, the transmission power of the communication between the first wireless device and the second wireless device is a third transmission power, and the third transmission power is smaller than the first transmission power.

Based on the above technical solution, after determining a good transmission parameter (e.g. a target transmission power or a first transmission power), if the current (e.g. referred to as a first period) communication quality does not satisfy a certain condition (e.g. referred to as a preset first condition), at a second period, at a first rate, a transmission power (e.g. referred to as a third transmission power) of the first wireless device and the second wireless device during communication may be smaller than an original transmission power (e.g. referred to as a first transmission power). In other words, the transmit power may be backed off. It should be understood that after the transmission power is backed off, it may be determined again whether the communication quality satisfies the preset condition to determine the transmission power when the first wireless device communicates with the second wireless device for the next period.

With reference to the first aspect, in certain implementation manners of the first aspect, the third transmission power is the preset transmission power specification.

Based on the technical scheme, if the power increase negotiation fails, the power is returned to the transmission power specification negotiation (which may be gradual power return), and then whether the communication quality meets the preset condition is judged, so that the communication failure caused by the deterioration of the quality of the power signal is avoided.

With reference to the first aspect, in certain implementations of the first aspect, the determining, by the first wireless device, a target transmit power profile includes: and when the preset second condition is met, the first wireless equipment determines the target transmission power specification.

Based on the above technical solution, the first wireless device may determine the target transmission power specification according to a trigger condition (e.g. a preset second condition), for example, the target transmission power specification may be periodically determined, and the first wireless device is triggered to determine the target transmission power specification. Or when external factors change, such as the environmental temperature or the antenna performance, the first wireless device is triggered to determine the target transmitting power specification, so that the influence of index reduction on the communication performance caused by strong environmental change, long-term work, equipment aging and the like is avoided.

Based on the technical scheme, the upper limit (for example, recorded as target transmitting power) of the transmitting power at a certain speed is larger than the preset transmitting power, so that the condition that the actual maximum capacity of the single boards output by the production line is possibly different is considered, the maximum coverage capacity of the first wireless equipment (for example, WIFi products) is exerted as much as possible, and the coverage range is improved.

The term "article of manufacture" as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media.

The scenario shown in fig. 1 is only one scenario that may be applied in the embodiments of the present application, and may also be applied in other systems that support power adjustment, for example. The number of terminal devices in the wireless local area network is not limited to 4, the number of APs is not limited to 3, and the number of terminal devices and APs may be any reasonable number. The controller may not be present in the wireless local area network shown in fig. 1.

WIreless-Fidelity (WiFi) is a WIreless local area network technology that connects devices to each other in a WIreless manner. Existing network WiFi needs to meet signal strength requirements, coverage requirements, throughput requirements, long-distance user experience, and the like.

Considering that the power calibration of the production line may have errors, in order to ensure the quality of the transmitted signal, the straight-through rate of the production line, and the like, a margin is usually reserved for the specification of the maximum radio frequency transmission power, that is, the transmission power of most devices has a margin. The line power accuracy is typically in the range of +2dB/-2dB. In other words, the radio frequency specification defines that there is a power margin of 2 decibels (dB) in a typical state, that is, most of the produced products satisfy a vector magnitude Error (EVM), and the transmission power has a power margin of about 2dB.

Wherein, the transmitting power is the working power of the transmitting antenna of the wireless product, and the unit is dBm. The transmission power may determine the strength and distance of the wireless signal, with the greater the power, the stronger the signal. Figure 2 shows a production transmit power distribution statistical chart. There is typically a limit on the maximum transmit power, i.e., there is typically a limit on the transmit power specification. As shown in FIG. 2, the upper specification limit is 15.00 decibel-milliwatts (dBm) and the lower specification limit is 9.00dBm. In a wireless product design, a target power (target power) is used as a design basis, and on the premise of meeting the requirements of a spectrum board and an EVM (enhanced correlation matrix), the larger the transmission power is, the better the performance is. The effect of the theoretical transmit power level on the coverage is shown in table 1 below.

TABLE 1

Increase in transmission power (dB)	Coverage is increased by a factor of
		1	1.12
2	1.26
		3	1.41
4	1.58

As can be seen from table 1, the transmission power is increased by 1dB, and the coverage is increased by 1.12 times, in other words, the transmission power differs by 1dB, which affects the coverage radius by 12%; the transmitting power is increased by 2dB, the coverage area is increased by 1.26 times, in other words, the transmitting power is different by 2dB, and the influence on the coverage radius is 26%; the transmitting power is increased by 3dB, the coverage area is increased by 1.41 times, in other words, the transmitting power is different by 3dB, and the influence on the coverage radius is 41 percent; the transmitted power is increased by 4dB and the coverage is increased by 1.58 times, in other words, the transmitted power differs by 4dB, affecting the coverage radius at 58%.

The EVM is an index considering the quality of the modulation signal, and has a unit of dB. The smaller the EVM, the better the signal quality. In a wireless product, the transmission power and the EVM are correlated, and the larger the transmission power, the larger the EVM, i.e. the worse the signal quality, so in practical applications, a compromise is generally made between the transmission power and the EVM. Fig. 3 shows a schematic diagram of the relationship of the transmission power to the EVM in connection with four lines a, B, C, D. As can be seen from fig. 3, the transmission power (e.g., the intersection a of the line a and the target power, the intersection B of the line B and the target power, the intersection C of the line C and the target power, and the intersection D of the line D and the target power in the figure) has a power margin of about 2dB. As can be seen from Table 1, the difference in the transmission power is 2dB, and the effect on the coverage radius is 26%. According to the power statistics of the production line and the signal quality relation, most of the WiFi products have the coverage capacity of 26% and can be mined.

Fig. 4 shows one way of WiFi rate negotiation. As shown in fig. 4, negotiation is started from the highest rate, that is, rate negotiation is performed from the highest rate; then setting the radio frequency power specification under the speed; then, whether the equipment is in good communication is judged: if the communication is good, maintaining the rate communication; if there is no good communication, the AP transmission rate is reduced to the next order rate and negotiation is continued.

The radio frequency transmission power used by general services is usually the transmission power specification, and the radio frequency transmission power used by general services does not exceed the transmission power specification for transmission. The WiFi rate negotiation method shown in fig. 4 does not consider the situation that the actual maximum capabilities of the single boards produced by the production line may be different, and cannot exert the maximum coverage capability of the WiFi product.

In view of this, an embodiment of the present application provides a method for increasing power and storing an actually increased transmission power specification based on an original transmission power specification in a communication process, so that not only can the maximum coverage capability of a network device be exerted, but also communication performance can be ensured.

It should be understood that in the embodiments shown below, "transmit power specification", "radio frequency power specification", "radio frequency transmit power specification" are often used interchangeably, but those skilled in the art will understand the meaning. For a network device (e.g., a wireless local area network product), the "transmission power specification", "radio frequency power specification", "radio frequency transmission power specification" all represent an upper limit of the transmission power of the network device. Therefore, in the embodiments of the present application, the intended meanings thereof are consistent when the differences are not emphasized.

It should also be understood that in the embodiments illustrated below, the first, second and various numerical references are only used for descriptive convenience and are not intended to limit the scope of the embodiments of the present application. E.g., to distinguish between different wireless devices, etc.

It should also be understood that in the embodiments illustrated below, references to "saving" may refer to saving in one or more memories. The one or more memories may be provided separately or integrated in the encoder or decoder, the processor, or the communication device. The one or more memories may also be provided separately, or integrated into a decoder, a processor, or a communication device. The type of memory may be any form of storage medium and is not intended to be limiting of the present application.

It is also understood that "at least one" means one or more and "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, and c, may represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

Fig. 5 is a diagram illustrating a method 200 for determining transmit parameters according to an embodiment of the present application. In the method shown in fig. 5, the first wireless device may be a network device, such as the AP shown in fig. 1, and the second wireless device may be a terminal device, such as the terminal device shown in fig. 1. Method 200 includes steps 210 through 240, which are described in detail below.

In step 210, the first wireless device determines a target transmit power specification for the first rate.

The transmission parameter includes a target transmission power specification (i.e., an instance of a target transmission power) or a first transmission power. The first transmit power is a transmit power used at a first rate, the transmit power being less than or equal to a target transmit power specification. The target transmit power specification is greater than the original transmit power specification (i.e., an instance of the predetermined transmit power) and less than or equal to a sum of the original transmit power specification and a predetermined power margin. In other words, any value of (N1, N2) is taken as the size of the target transmission power specification, wherein N1 represents the size of the original transmission power specification, and N2 represents the sum of the original transmission power specification and the preset power margin.

The original transmission power specification may be preset or predefined, for example, a power specification set uniformly during production. Each WiFi rate may correspond to an original transmission power specification, and for different WiFi rates, the original power specifications may be the same or different, which is not limited herein. The preset power margin is predefined, for example, 2dB, and is not limited thereto.

The first wireless device determines a target transmit power specification, which may be for each WiFi rate (i.e., an instance of the first rate). Optionally, the target transmit power specification is determined based on the original transmit power specification and a preset value. The preset value is less than or equal to the preset power margin, and the preset value may be a preset threshold, or may be determined according to a simulation experiment or experience, or may be given by production statistics, and the like, which is not limited in the present application. Table 2 exemplifies five WiFi rates MCS0NSS1, MCS1NSS1, MCS2NSS1, MCS3NSS1, MCS4NSS1, and MCS5NSS 1.

TABLE 2

It should be understood that table 2 is merely an exemplary illustration and the present application is not limited thereto.

Alternatively, the target transmit power specification may be a sum of the original transmit power specification and a preset value. Taking the five WiFi rates in table 2 as an example, the original and target transmit power specifications can be as shown in table 3 below.

TABLE 3

It should be understood that table 3 is only an exemplary illustration, and the present application is not limited thereto, and may be, for example, a product of the original transmission power specification and a preset value, where the preset value may be a number greater than 1 or greater than 1 and less than 2.

In step 220, the first wireless device and the second wireless device communicate based on the target transmit power specification.

It should be understood that the first wireless device and the second wireless device communicate based on the target transmit power specification and do not represent the transmit power at which the first wireless device and the second wireless device communicate as the target transmit power specification. In an embodiment of the application, the transmission power of the first wireless device and the second wireless device when communicating is less than or equal to the target transmission power specification.

In the embodiment of the application, in the rate negotiation process, the specification of the set transmitting power is larger than the original transmitting power specification and is smaller than or equal to the sum of the original transmitting power specification and the power margin, the condition that the actual maximum capacity of the single boards output by a production line is possibly different is considered, and the power margin reserved by power fluctuation of production consistency is improved, so that the maximum covering capacity of first wireless equipment (such as WIFi products) is exerted as much as possible, the covering range is improved, and the communication performance is further improved. For example, if the target transmit power specification is raised by about 2dB compared to the original transmit power specification, the coverage radius may be raised by about 20%.

Optionally, before step 220, the method 200 includes step 230, in which step 230 the first wireless device determines the communication quality of the second wireless device.

After the first wireless device determines a target transmit power specification, it may determine whether the second wireless device may communicate well at the first rate based on the target transmit power specification. For example, it may be determined whether the communication quality of the second wireless device is good.

If the communication quality satisfies a predetermined condition (an example of a predetermined first condition), the method 200 may include step 240, where the first wireless device records the transmission power specification of the first rate as the target transmission power specification in step 240.

In the embodiment of the application, after the target transmission power specification is determined and the transmission power is increased, whether the communication quality is deteriorated due to the increase of the transmission power is judged, and under the condition that the communication quality is not deteriorated, the transmission power specification is determined to be the target transmission power specification, so that the service performance can be ensured.

The preset condition may be that the communication quality is good, for example, when the communication quality is good, the first wireless device records the transmission power specification as the target transmission power specification. Alternatively, the preset condition may be that the communication quality of the first wireless device when communicating under the target transmission power specification is better than or the same as or not much different from the communication quality when communicating under the original transmission power specification, that is, the communication quality of the first wireless device when communicating under the target transmission power specification is compared with the communication quality of the first wireless device when communicating under the original transmission power specification.

It should be understood that, in the embodiment of the present application, the preset condition is used to determine whether the communication quality is good, and then determine whether to confirm the target transmission power specification as the transmission power specification. Any method that can determine whether the communication quality is good falls within the scope of the present application.

And recording the transmission power of the first wireless equipment and the second wireless equipment during communication as a first transmission power, wherein the first transmission power is less than or equal to the target transmission power specification.

Alternatively, the first wireless device and the second wireless device may be based on a second transmission power, which is greater than or equal to the first transmission power, if the communication quality satisfies a preset condition.

Alternatively, the first wireless device and the second wireless device may be based on a third transmit power, which is less than the first transmit power, if the communication quality does not satisfy the preset condition. Or, optionally, the first wireless device may communicate based on the original transmission power specification, or reduce the transmission power and re-determine whether the communication quality satisfies a preset condition.

Specifically, if the communication quality is not good and the first transmission power is less than the original transmission power specification, the first wireless device may decrease the transmission rate to the next order rate and continue the steps 210 through 240 as described above. Or if the communication quality is not good and the first transmission power is greater than or equal to the original transmission power specification, the first wireless device uses the second transmission power to communicate with the second wireless device, and judges whether the current communication quality is good. The second transmission power is smaller than the first transmission power, for example, the first transmission power is backed off by 1dB or 0.5dB to obtain the second transmission power.

Optionally, the first wireless device may also determine the target transmit power specification according to a trigger condition (i.e. an example of a preset second condition).

In one possible implementation, the first wireless device may periodically determine the target transmit power specification, where the fixed period may be predefined, or empirically set, etc.

Yet another possible implementation is to trigger the first wireless device to determine the target transmit power specification when the external factors change. For example, when the environmental temperature or the antenna performance changes, the first wireless device is triggered to determine the target transmission power specification, so that the influence on the communication performance caused by index reduction due to strong environmental change, long-term operation, equipment aging and the like is avoided.

Based on the technical scheme, considering that the actual maximum capacities of the single boards produced by the production line are possibly different, the emission power specification can be improved in the service use process, namely, the target emission power specification is determined based on the original emission power specification and the preset value, so that the coverage range can be improved as much as possible in consideration of the actual capacity. After the target transmission power is determined, whether the communication quality meets a preset condition (for example, whether the communication quality is good) is judged, if the communication quality meets the preset condition, the transmission power specification of the second wireless device is recorded as the target transmission power specification, and communication is performed based on the target transmission power specification, so that the transmission power specification is improved, and meanwhile, the communication performance is guaranteed. In addition, in the speed negotiation process, if the power increase negotiation fails, the power is gradually returned to the transmission power specification negotiation, and then the speed reduction negotiation learning is carried out, so that the communication failure caused by the deterioration of the quality of the power signal is avoided.

Fig. 6 is a schematic flow chart diagram of a method 300 of determining transmit parameters in accordance with yet another embodiment of the present application. The method 300 may be performed by a network device, such as the AP shown in fig. 1, and the device in the method 300 may be a terminal device, such as the terminal device shown in fig. 1. Method 300 includes steps 310 through 330, which are described in detail below.

In step 310, the boosted power profile learning is started from the highest rate.

The boosted power specification learning may be understood as a process of determining a target transmission power specification in the embodiment of the present application, for example, taking any value from (N1, N2) as the size of the target transmission power specification, where N1 represents the size of the original transmission power specification, and N2 represents the sum of the original transmission power specification and a preset power margin.

Each WiFi rate may correspond to an original transmission power specification, and for different WiFi rates, the original power specifications may be the same or different, which is not limited, as shown in table 2 above. As shown in fig. 6, the boost power specification learning may be started from the highest rate (i.e., an example of the first rate) supported by the device, and the embodiment of the present application is not limited thereto. For example, the boost power specification learning may be started from any rate, or the boost power specification learning may be started from the current rate.

In step 320, a target transmit power specification is set.

The target transmit power specification is determined during communication between the first wireless device and the second wireless device. The target transmit power specification (i.e., an instance of the target transmit power) is greater than the original transmit power specification (i.e., an instance of the preset transmit power) and is less than or equal to a sum of the original transmit power specification and a preset power margin. One possible implementation is based on the original transmit power specification (i.e., an example of a predefined transmit power specification) and a preset value.

Step 320 is similar to step 210 of method 200, and is not repeated here for brevity.

In step 330, it is determined whether the device is able to communicate well.

After the first wireless device determines the target transmit power specification, it may determine whether the second wireless device may communicate well.

In one possible implementation manner, if the communication quality satisfies a preset condition (i.e., an example of the preset first condition), in step 331, the transmission power specification of the device at the rate is recorded, i.e., the transmission power specification of the device at the rate is the target transmission power specification.

The preset condition may be that the communication quality is good, for example, when the communication quality is good, the first wireless device records the transmission power specification as the target transmission power specification. Alternatively, the preset condition may be that the communication quality of the first wireless device when communicating under the target transmission power specification is better than or the same as the communication quality when communicating under the original transmission power specification, i.e., the communication quality of the first wireless device when communicating under the target transmission power specification is compared with the communication quality of the first wireless device when communicating under the original transmission power specification.

It should be understood that, in the embodiment of the present application, the preset condition is used to determine whether the communication quality is good, and any method that can determine whether the communication quality is good falls within the scope of the present application.

In another possible implementation manner, if the communication quality does not satisfy the preset condition, it is determined whether the current transmission power is smaller than the original transmission power specification in step 332.

Recording the transmission power of the first wireless equipment and the second wireless equipment during communication as a first transmission power, and judging whether the first transmission power is smaller than the original transmission power specification. The first transmit power is less than or equal to the target transmit power specification.

If the first transmit power is less than the original transmit power specification, then the transmit rate is reduced to the next order rate and learning continues in step 3321. I.e., the transmission rate is reduced to the next order rate, steps 320, 330 are performed.

If the first transmit power is greater than or equal to the original transmit power specification, then in step 3322, the current transmit power is backed off by a preset threshold, and then the device continues to determine whether it can communicate well. That is, the first transmission power back-off is preset to a threshold, for example, the first transmission power is back-off by 1dB or 0.5dB, and then it is determined whether the device can perform good communication.

Alternatively, the boost power specification learning may be triggered according to a trigger condition (i.e., an example of a preset second condition). For example, power profile learning may be periodically boosted, where a fixed period may be predefined, or empirically set, and so forth. For another example, when the external factor changes, the boosted power specification learning is triggered, and when the environment temperature or the antenna performance changes, the boosted power specification learning is triggered, so that the influence of index reduction on the communication performance caused by the reasons of strong environment change, long-term work, equipment aging and the like is avoided.

Based on the technical scheme, the practical maximum capacity of the single boards produced by the production line is possibly different, and the power-improving specification learning can be carried out in the service using process. In addition, in the process of rate negotiation, a certain power value (namely, an example of a preset value) is increased on each rate power specification for negotiation, if the power increase negotiation fails, the power is gradually returned to the transmission power specification negotiation, and then the rate reduction negotiation learning is carried out, so that the communication failure caused by the deterioration of the quality of the power signal is avoided. For example, assuming that the transmission power specification is improved by about 2dB through power learning and the rate negotiation is successful, the coverage radius can be improved by about 20%.
