The wireless hotspot device 100 is used to generate a WIFI signal. The generated WIFI signal is filtered by the band-pass filter device 200 and then sent to the frequency shifting device 300. The frequency shifting device 300 can realize the frequency shift of the signal, and move the high frequency band signal to the low frequency band. The latter signal is transmitted through the antenna switch device 400 and the antenna device 500. Since the low-frequency signal has a longer wavelength and stronger penetrating power, moving the WIFI signal to the low frequency band and then transmitting it through the antenna device 500 can increase the coverage of the WIFI signal, and is not blocked by obstacles such as buildings or trees. It is more suitable for bad weather and has high reliability.

[Corrected according to Rule 91 29.09.2019] Specifically, the wireless hotspot device 100 can provide access to the wired LAN by the multi-channel WIFI signal transceiver device, and can also provide access to the multi-channel WIFI signal transceiver device from the wired LAN. Wireless workstations within the coverage of 100 access points can communicate with each other through it. When the multi-channel WIFI signal transceiver device transmits WIFI signals, the wireless hotspot device 100 accesses the network, processes the connected network signals and sends them to the band-pass filter device 200 in the form of WIFI signals, and the band-pass filter device 200 performs processing on the WIFI signals. After filtering, it is sent to the frequency shifting device 300. The frequency shifting device 300 can shift the frequency of the signal, move the high frequency band signal to the low frequency band, and then transmit the moved signal through the antenna switch device 400 and the antenna device 500. When the multi-channel WIFI signal transceiver device receives the WIFI signal, the antenna device 500 can sense the electromagnetic signal in the space and then send it to the antenna switch device 400. The antenna switch device 400 transmits the signal to the frequency shift device 300, and the frequency shift device 300 can realize the signal The frequency shift is to move the low-frequency signal to the high-frequency band, and the moved signal is then transmitted to the band-pass filter device 200 for filtering processing, and the filtered signal is sent to the wireless hotspot device 100, so that the user can use the wireless hotspot device 100 to achieve Wired LAN access to multi-channel WIFI signal transceiver device.

The band-pass filter device 200 is mainly used for filtering the signals flowing through, allowing signals of a specific frequency band to pass while shielding signals of other frequency bands. According to different actual requirements, band-pass filter devices 200 with different structures can be used, so that the retained and filtered frequency band signals are different, and the application range is wider.

The frequency shifting device 300 adopts the analog mixer technology to realize the shifting of the high frequency band signal to the low frequency band or the low frequency band signal to the high frequency band. The structure of the frequency shifting device 300 is not unique. For example, an analog multiplier inverter or a transistor mixer may be used. It is understood that the frequency shifting device 300 may also adopt other structures, as long as those skilled in the art think it can be implemented.

[Correction 29.09.2019 according to Rule 91] The number of frequency transfer devices 300, bandpass filter devices 200 and wireless hotspot devices 100 is equal to the number of antenna switch devices 400, and each frequency transfer device 300 is connected to the corresponding bandpass filter device 200, Each band-pass filter device 200 is connected to the corresponding wireless hotspot device 100 respectively.

For example, when the number of antenna array layers 510 is two layers, the theoretical gain can be increased by 3dB, and when the number of antenna array layers 510 is three layers, the gain can be theoretically increased by 5dB. When the number of antenna array layers 510 is three or more, higher gain can be increased, so that the WIFI signal received and sent by the multi-channel WIFI signal transceiver device has a longer transmission distance, a larger coverage area, and high reliability.

[Corrected 29.09.2019 according to Rule 91] In one embodiment, please refer to Figure 2. The multi-channel WIFI signal transceiver device further includes a control device 900 and a measuring device 800. The number of measuring devices 800 is equal to the number of wireless hotspot devices 100. Each measuring device 800 is connected to the corresponding wireless hotspot device 100, each measuring device 800 is connected to the control device 900, and the control device 900 is connected to the wireless hotspot device 100; the measuring device 800 is used to measure the connection signal of each wireless hotspot device 100 to obtain the measurement The result is sent to the control device 900, and the control device 900 controls the output power of each wireless hotspot device 100 according to the measurement result.

[Correction 29.09.2019 according to Rule 91] Specifically, in a signal channel, a measuring device 800 is connected to a wireless hotspot device 100, and the measuring device 800 is used to measure the connection signal of the wireless hotspot device 100, and the measurement result is sent to The control device 900, since the number of the measuring device 800 and the wireless hotspot device 100 are both more than two, the multi-channel WIFI signal transceiving device includes multiple signal transceiving channels, and the measuring device 800 in each signal channel corresponds to the wireless hotspot device 100 After the control device 900 receives the measurement results of each channel, the control device 900 controls the output power of the wireless hotspot device 100 in each signal channel according to the measurement results, which can increase the power of some wireless hotspot devices 100 Output power, reduce the output power of some wireless hotspot devices 100 or maintain the output power of some wireless hotspot devices 100 unchanged. For example, when the analysis result indicates that the current filtered signal strength exceeds the upper limit of strength, it indicates that the current filtered signal strength is too high. At this time, the control device 900 controls the wireless hotspot device 100 to reduce the output power. When the analysis result indicates that the current filtered signal strength is less than the lower limit of strength, it indicates that the current filtered signal strength is too small, and the control device 900 controls the wireless hotspot device 100 to increase the output power. When the analysis result indicates that the current filtered signal strength is within the default range, it indicates that the current filtered signal strength is normal. At this time, the control device 900 controls the wireless hotspot device 100 to maintain the current output power unchanged. The structure of the measuring device 800 is not unique, and different structures can correspond to different signal types, as a basis for the control device 900 to control the output power of the wireless hotspot device 100, and can be adjusted according to actual needs. The type of the control device 900 is not unique. For example, it may be CPLD (Complex Programmable Logic Device), FPGA (Field-Programmable Gate Array, field programmable gate array) or single-chip microcomputer. As the control device 900, the CPLD has the advantages of flexible programming, high integration, wide application range, and low design and manufacturing cost. FPGA as the control device 900 has low design cost and high working stability. The single-chip microcomputer has the advantages of small size, simple structure and high reliability. It can be understood that, in other embodiments, the control device 900 may also use other devices, as long as those skilled in the art think that it can be implemented.

In one embodiment, the measurement result includes the received signal strength indicator value. The control device 700 is configured to control the output power of the wireless hotspot device 100 according to the received signal strength indication value and the default signal strength reference data.

[Corrected according to Rule 91 29.09.2019] Specifically, the received signal strength indicator value, namely RSSI (Received Signal Strength Indicator) value, is the broadband received power on the received channel bandwidth, which can be used as one of the basis for evaluating the quality of the data connection . The default signal strength reference data can be the default upper limit value, lower limit value or reference range. Taking the default signal strength reference data as the default upper limit value, for example, when the received signal strength indicator value sent by the measuring device 800 When the upper limit is exceeded, it is considered that there is reverse link interference in the data transmission channel. At this time, the control device 900 controls the wireless hotspot device 100 in the signal channel to reduce the output power to reduce the influence of signal interference and improve signal transmission. Reliability. It can be understood that, in other embodiments, when the default signal strength reference data is the default lower limit or reference range, when the received signal strength indication value sent by the measuring device 800 is lower than the preset lower limit or When the preset reference range is exceeded, the control device 900 can adjust the output power of the wireless hotspot device 100 accordingly to improve the working performance of the wireless hotspot device 100. When the measurement result includes the received signal strength indicator value, the corresponding measurement device 800 may be a chip of model CC2530, which has a high integration level and can obtain an accurate RSSI value.

[Corrected according to Rule 91 29.09.2019] In one embodiment, the measurement result includes a channel quality indicator value. The control device 900 is configured to control the output power of the wireless hotspot device 100 according to the channel quality indicator value and the default channel quality reference data.

[Corrected according to Rule 91 29.09.2019] Specifically, the channel quality indicator value, namely the CQI (Channel Quality Indicator, channel quality indicator) value, is one of the measurement standards of the communication quality of the wireless channel, and corresponds to the signal-to-noise ratio of the channel , Which means that CQI is directly related to network coverage. Generally speaking, the CQI value ranges from 0 to 31. When the CQI value is 0, the channel quality is the worst. When the CQI value is 31, the channel quality is the best, and the common value is 12-24. The default channel quality reference data can be the default upper limit, lower limit, or reference range. If the default channel quality reference data is the default upper limit, when the received signal strength indicator value sent by the measuring device 800 exceeds this When the upper limit value is reached, it is considered that the signal quality transmitted in the data transmission channel is high. At this time, the control device 900 can control the wireless hotspot device 100 to appropriately reduce the output power to save the resource cost of the wireless hotspot device 100. The reference data is the default lower limit value. When the received signal strength indicator value sent by the measuring device 800 is lower than the lower limit value, the signal quality transmitted in the data transmission channel is considered to be low, and the control device 900 can control the wireless The hotspot device 100 appropriately increases the output power to ensure the quality of the transmission signal and improve the reliability of the multi-channel WIFI signal transceiving device.

In one embodiment, the measurement result includes an access load value. The control device 900 is configured to control the output power of each wireless hotspot device 100 according to the access load value and the default access load reference data.

[Correction 29.09.2019 according to Rule 91] Specifically, under the action of the high-gain antenna device 500, the coverage of the WIFI signal increases, and the multi-channel WIFI signal transceiver device includes multiple signal channels, which may cause the wireless hotspot device 100 The problem of unbalanced load. The measuring device 800 measures the load connected by the wireless hotspot device 100 in each signal channel to obtain the measurement result and send it to the control device 900. The control device 900 is used to control each wireless device according to the access load value and the default access load reference data. The output power of the hotspot device 100. The default access load reference data can be the default upper limit value, lower limit value or reference range. Taking the default access load reference data as the default upper limit value as an example, when a certain measuring device 800 sends an access When the load value exceeds the upper limit, it is considered that the load of the wireless hotspot device 100 in the data transmission channel is too large. At this time, the control device 900 controls the wireless hotspot device 100 to appropriately reduce the output power, and can also control wireless in other signal channels. The output power of the hotspot device 100 is appropriately increased, so as to guide some users of the wireless hotspot device 100 with a heavy load to nearby idler wireless hotspot devices 100 to achieve the effect of load balancing and increase the throughput of the network. Further, when the access load of the wireless hotspot device 100 is not within a suitable range, the number of antenna array layers 510 used for access in the signal channel where the wireless hotspot device 100 is located can also be adjusted to adjust the multi-channel WIFI signal transmission and reception. The signal coverage of the device, thereby achieving the effect of adjusting the access load of the wireless hotspot device 100.

In one embodiment, the measurement result includes the number of access users. The control device 900 is used for controlling the output power of each wireless hotspot device 100 according to the number of access users and the reference data of the default number of access users.

[Corrected 29.09.2019 in accordance with Rule 91] Specifically, the measuring device 800 measures the number of users connected to the wireless hotspot device 100 in each signal channel to obtain the measurement result and send it to the control device 900, which is used for use according to the access The reference data of the number of users and the default number of access users controls the output power of each wireless hotspot device 100. The default reference data for the number of connected users can be the default upper limit, lower limit or reference range. Taking the preset reference data for the number of connected users as the default upper limit value, for example, when a certain measuring device 800 sends it When the number of connected users exceeds the upper limit, it is considered that there are too many users connected to the wireless hotspot device 100 in the data transmission channel. At this time, the control device 900 controls the wireless hotspot device 100 to appropriately reduce the output power, and can also control The output power of the wireless hotspot device 100 in other signal channels is appropriately increased, so that some users of this wireless hotspot device 100 can reside on relatively idle nearby wireless hotspot devices 100, and guide users to evenly reside on each wireless hotspot device 100. To optimize network performance. Further, when the number of access users of the wireless hotspot device 100 is not within the proper range, the number of antenna array layers 510 used for access in the signal channel where the wireless hotspot device 100 is located can also be adjusted to adjust the multi-channel WIFI signal The signal coverage of the transceiver device can further adjust the number of users connected to the wireless hotspot device 100.

[Corrected according to Rule 91 29.09.2019] Further, the measurement result includes at least one of the received signal strength indicator value, the channel quality indicator value, the access load value, and the number of access users, so that the measurement results all include the signal strength indicator For example, the control device 900 is provided with corresponding signal strength reference data, channel quality reference data, access load reference data, and access user number reference data. The measurement result is compared with the reference data of the corresponding signal type, and the control device 900 controls the output power of the wireless hotspot device 100 according to the comparison result. When the measurement results all include the signal strength indicator value, the channel quality indicator value, the access load value, and the number of access users, further judgment rules can be set to determine the comparative priority of different types of signals. For example, setting priorities or weighting coefficients for different signal types, specifically taking the setting of weighting coefficients as an example, the control device 900 can perform a weighted summation according to different types of values and corresponding weighting coefficients, and perform a weighted summation based on the summation result and the default reference data. In contrast, to control the output power of the wireless hotspot device 100.

[Correction 29.09.2019 according to Rule 91] In one embodiment, please refer to FIG. 3, the band-pass filter device 200 includes a first band-pass filter 210 and a second band-pass filter 220, and the frequency shift device 300 includes a transmission channel frequency The shifter 310 and the receiving channel frequency shifter 320, the first band pass filter 210 is connected to the wireless hotspot device 100, the transmitting channel frequency shifter 310 is connected to the first band pass filter 210, and the antenna switch device 400 is connected to the transmitting channel frequency shifter 310 , The second band pass filter 220 is connected to the wireless hotspot device 100, the receiving channel frequency shifter 320 is connected to the second band pass filter 220, and the antenna switch device 400 is connected to the receiving channel frequency shifter 320.

[Corrected according to Rule 91 29.09.2019] Specifically, the transmission and reception of WIFI signals in the multi-channel WIFI signal transceiver device are respectively transmitted through the signal transmission channel and the signal reception channel. The signal transmission channel includes the first bandpass filter 210 and the transmission channel The frequency shifter 310, the signal receiving channel includes a second band pass filter 220 and the receiving channel frequency shifter 320. When transmitting a signal, the wireless hotspot device 100 generates a WIFI signal. The frequency of the signal generated at this time is generally higher. After the high-frequency signal is transmitted to the first band-pass filter 210, only signals of a specific frequency band are retained, and then transmitted to the first frequency The mover, the first frequency mover moves the signal of the specific frequency band to the low frequency band and sends it to the antenna switch device 400. The antenna device 500 receives the signal transmitted by the antenna switch device 400 and radiates it into the space to complete the transmission of the WIFI signal. Since the signal transmitted by the antenna device 500 is a low-frequency signal, it has strong penetration capability and a large signal coverage. When receiving a signal, the electromagnetic signal from the space received by the antenna device 500 is sent to the second band-pass filter 220 via the antenna switch device 400, and the second band-pass filter 220 filters out the clutter in the signal and sends it to the wireless hotspot device 100. The wireless hotspot device 100 processes the signal and completes the reception of the WIFI signal.

[Corrected 29.09.2019 according to Rule 91] In this embodiment, the number of antenna array layers 510 connected to each antenna switch device 400 is sequentially increased as an example, the number of antenna switch devices 400 is N, and the first antenna switch device 400 is connected to two antenna array layers 510, the second antenna switch device 400 is connected to three antenna array layers 510, and so on, the Nth antenna switch device 400 is connected to N+1 antenna array layers 510. Taking the first antenna switch device 400 as an example, two antenna array layers 510 are connected to the antenna switch device 400, and the antenna switch device 400 is sequentially connected to the transmitting channel frequency shifter 310, the first band pass filter 210 and the wireless hot spot device 100, The antenna switch device 400 is also sequentially connected to the receiving channel frequency shifter 320, the second band pass filter 220 and the wireless hotspot device 100 to form a signal transmitting channel and a signal receiving channel, respectively. By separately configuring each antenna switch device 400 with a set of frequency shifting device 300 and band-pass filter device 200 to form multiple signal transmission channels and signal receiving channels, multi-beam configuration can be realized, and multi-channel WIFI signal transceiver devices can be expanded The scope of application. Since the number of antenna array layers 510 connected to each antenna switch device 400 is different, the gain effect of each antenna switch device 400 is also different. Specifically, the greater the number of antenna array layers 510, the higher the gain. In actual use, the corresponding number of antenna array layers 510 can be adjusted to be put into use according to requirements such as signal strength and coverage, which is conducive to rational use of resources and improves the reliability of the multi-channel WIFI signal transceiving device.

[Corrected 29.09.2019 according to Rule 91] The types of the first band-pass filter 210, the second band-pass filter 220, the transmitting channel frequency shifter 310 and the receiving channel frequency shifter 320 are not unique, and in this embodiment Take the high-frequency band signal frequency of 2.4GHz and the low-frequency band signal frequency of 700MHz as an example, the first bandpass filter 210 and the second bandpass filter 220 are both 2.4GHz bandpass filters, and only those with a frequency of 2.4GHz are allowed When the signal passes, the signals of other frequencies are filtered out to improve the quality of the transmitted signal. The transmitting channel frequency shifter 310 is a 2.4GHz to 700MHz frequency shifter, which converts the high-frequency signal with a frequency of 2.4GHz into a 700MHz low-frequency signal and then transmits it from the antenna device 500 through the antenna switch device 400, which is beneficial to improve the signal coverage range. The receiving channel frequency shifter 320 is a 700MHz to 2.4GHz frequency shifter, which converts the low-frequency signal with a frequency of 700MHz into a 2.4GHz high-frequency signal and sends it to the second band-pass filter 220, and the second band-pass filter 220 filters it For signals of other frequencies, only signals with a frequency of 2.4 GHz are reserved and then sent to the wireless hotspot device 100 for network conversion and sharing, which is beneficial to improving the working performance of the WIFI signal. It can be understood that the frequency of the high-band signal is not limited to 2.4GHz, but can also be 3.5GHz, 5.8GHz or other frequencies. The frequency of the low-band signal is not limited to 700MHz, but can also be 400MHz, 800MHz, 900MHz, 1800MHz, 1900MHz , 2100MHz, 3300MHz or other frequencies, as long as those skilled in the art think it can be implemented. Realizing signal transmission and reception by different lines can reduce the mutual interference between the transmitting channel and the receiving channel and improve the performance of signal transmission.
