Disclosed are methods and systems for interactive dynamic interference testing of wireless environments, which can emulate wireless traffic for multiple homes, apartments and offices. The emulated wireless environment can emulate a wide variety of 802.11 traffic, as well as other types of traffic. Some embodiments can also control any of the power level of interference, as well as the attenuation between devices, such as between access points and clients. The system and method can be used to monitor the performance of a device under test (DUT) under one or more interference conditions, and can be used to evaluate and modify the dynamic behavior of the DUT and other devices under different operating scenarios.
Description
- This Application claims priority from U.S. Provisional Application No. 62/406,325, filed Oct. 10, 2016, which is incorporated herein in its entirety by this reference thereto.
- At least one embodiment of the present invention pertains to systems and processes for interference testing within wireless environments. At least one embodiment of the present invention pertains to systems and processes for dynamic modification of one or more operating parameters of a wireless device in a wireless environment.
- Wi-Fi devices are often set up or otherwise configured based on an assumption that the surrounding wireless environment includes little or no interference, and that neighboring wireless devices are also Wi-Fi devices, which operate in an expected manner.
- However, many wireless devices that generally comply with IEEE 802.11 standards do not fully or partially implement enhanced distributed channel access (EDCA) 802.11 standards, and are often not “fair” in how they operate in wireless environments that are shared with other devices.
- As well, some wireless devices that generally comply with IEEE 802.11 standards do not have good receivers, and as such, do not adequately detect other communication packets in densely populated areas.
- In addition, non Wi-Fi interference often occurs in Wi-Fi bands that have different protocols and physical layers, such as associated with any of Bluetooth devices that operate with respect to IEEE 802.15.4 standards, e.g., baby monitors, intercoms, or other commonly used devices.
- New protocols are being introduced for 802.11 bands, which do not follow 802.11 back off and rate control mechanisms, such as for long-term evolution (LTE) devices that operate in unlicensed spectrum (LTE-U), which use carrier-sensitive adaptive transmission (CSAT) to sense other users, and can adjust on/off LTE cycling, or LTE-LAA, such as to abide by region specific “listen before talk” (LBT) policy, such as to sense channel availability, and subsequently adjust on/off LTE cycling.
- Wireless devices are often configured to increase back-off when they detect interference, which often does not help when the devices share a medium with other devices.
- As well, data rates can drop as a function of rate control for a wireless device. As a result, when the length of packets increases in time, the performance can decrease, because the increased length of packets inherently increases the probability of collisions.
- One or more embodiments of the present invention are illustrated by way of example and not limitation in the figures of the accompanying drawings, in which like references indicate similar elements.

- Disclosed are methods and systems for interactive dynamic interference testing of wireless environments, which can emulate wireless traffic for multiple homes, apartments and offices. The emulated wireless environment can emulate a wide variety of 802.11 traffic, as well as other types of traffic. Some embodiments can also control any of the power level of interference, as well as the attenuation between devices, such as between access points and clients.

FIG. 1 is a schematic view of an illustrativewireless environment 10 having a plurality ofbuildings 12 andrelated infrastructure 16 located within aregion 14, e.g., a populated residential, business orindustrial environment 14, in which a variety ofwireless devices device - An illustrative building, e.g., a residence or
business 12, seen inFIG. 1 is located in a populatedarea 14, in which anaccess point 18 and one ormore devices 20 are configured to operate. For example, a wide variety ofaccess points 18 anddevices 20 are commonly used within a residential, business orindustrial environment 14, in which many of thedevices FIG. 2 ), such as betweendevices 20, and or between awireless device 20 and anaccess point 18, either directly or through awireless bridge 22. As well, numerous other devices, such as appliances, remote controllers, toys, consumer electronics, security systems, heaters, ventilation and/or air conditioning (HVAC) units, vehicles, and/or tools that commonly operate within a residential business orindustrial environment 14 can often interfere with wireless communication. - The illustrative
wireless environment 14 seen inFIG. 1 also includes numerous neighboringbuildings 12, which can similarly include one ormore access points 18,bridges 22, and a wide variety ofdevices 20, such as those that are configured to operate wirelessly within the environment, as well as other devices and/orappliances 20 that can contribute to interference 80 (FIG. 2 ). Somewireless environments 12 can include one or morewireless bridges 22, such as to extend the range betweenwireless devices 20 and anaccess point 18. In somewireless environments 14, one ormore access points 18 can be configured asbridges 22, such as between access points, or as a connection 62 (FIG. 2 ) between anaccess point 18 and a router 63 (FIG. 2 ) for connection to an external network 62 (FIG. 2 ). -
Interference 80 can also arise from other sources 78 (FIG. 2 ), such as from the use of mobile devices, vehicles, equipment, and/or even from theinfrastructure 16 itself, e.g., utility delivery, utility monitoring, content reception and transmission, community routers, etc. -
FIG. 2 shows an illustrative localwireless environment 60 associated with a building orproperty 12, in which operation of a device, such as anaccess point 18, awireless bridge 22, or otherwireless device 20, can be adversely effected by interference from any of local or external sources. Theillustrative building 12 seen inFIG. 2 , such as located within a populated area 14 (FIG. 1 ), includes awireless access point 18, which is connected 62 to anexternal network 64, such as through arouter 63. - The
illustrative access point 18 seen inFIG. 2 is configured to communicate withwireless devices 20 over a Wi-Fi network 84, such as directly or through anintermediate bridge 22, usingwireless signals 66, such as by transmitting adownlink signal 68 to awireless device 20, and/or by receiving anuplink signal 70 from thewireless device 20. While somewireless devices 20, e.g., 20 a, are specifically configured to communicate over a single Wi-Fi network 84,other devices 20 can be configured to operate over one or more available channels, e.g., 3G, 4G, LTE, etc. - As further illustrated in
FIG. 2 , alocal environment 60 can often include a wide varietyother devices 20 that can communicate 66 withother devices 20, directly and/or through anaccess point 18. For instance, such devices can include any of entertainment systems andgaming devices 20 b, security systems, HVAC controllers, ZigBee devices (IEEE 802.15 devices), and localwireless monitors 20 c andreceivers 20 d, e.g., baby monitoring systems. As well,other devices 74 can contributeunintended signals 76 to a local environment, even without intended wireless communication. For example,microwave ovens 74 and/or other appliances or tools are often operated in residential and/orbusiness environments 14, and can producesignals 76 during use that can interfere with the wireless operation ofother devices - As also seen in
FIG. 2 , interference signals 80 from one or moreexternal sources 78 can cause further interference within alocal environment 60, just as the operation ofdevices local environment 12 can result in interference that can be problematic for wireless operation in neighboringlocal environments 60. - As seen in
FIG. 1 andFIG. 2 , thespecific environment wireless devices devices downlink signals 68 and/oruplink signals 70. - A specific environment in which a
device - For example, within a
business environment 10,numerous devices 20, such as computers, printers, copiers, are often powered and operated during limited hours of operation during a business day, while many of thesedevices 20 are powered off at other times, such as at night, and/or on weekends. While somedevices 20 can be powered during other times, they may not require bandwidth for receiving and/or transmitting wireless signals during such downtime. Some devices are often required to be used at all times in a business environment, such as for HVAC systems, refrigerators, security and monitoring systems, servers and/oraccess points 18. Other devices are commonly used as needed during active business hours, such as microwave ovens, copiers, printers, and/or tools. - The operating environment within a
residence 12 can also change significantly, such as based on the requirements, habits and interests of the occupants. For instance, anillustrative residence 12 can include one ormore access points 18, one ormore bridges 22, computers, wireless phones, entertainment systems, and gaming consoles. In some households, one or more of the occupants can leave the residence during work and/or school hours. At other times, many of the occupants can be at home, and increase their use of wireless devices. In multiple-family buildings, thelocal interference 80 can increase significantly, in which somedevices 20 are operated on an as-needed basis, whileother devices 20 are powered continuously. - Furthermore, a
local wireless environment 60 can suffer from external interference 80 (FIG. 2 ) caused by the operation of other stationary and/or mobile sources, besides those related to neighboringbuildings 12. -

illustrative test system 100 a seen inFIG. 3 also includes aninterference set 120, such as controlled by an interference setcontroller 122 and monitored 108 by an interference setmonitor 124. While the illustrative interference setcontroller 122 and interference setmonitor 124 are shown as discrete components, in some system embodiments, the functions of the interference setcontroller 122 and interference setmonitor 124 can be performed by an integrated system controller. Furthermore, in some system embodiments 100, the functions of the interference setcontroller 122 and interference setmonitor 124 can be performed with a combined system controller that can also performDUT control 112 and/ormonitoring 114. - The interference set 120 seen in

In some embodiments of the test system 100, theinterference controller 122 and the interference monitor 124 can implemented by anintegrated interference controller 122 and monitor 124. Furthermore, the control parameters and monitored performance can be captured, stored and/or displayed, such as for analysis by testing personnel U. - The illustrative interference set 120 seen in

FIG. 4 is a schematic diagram of an alternate illustrative embodiment of a dynamic interference system 100, e.g., 100 b, which can emulate traffic from high densitywireless communication environments FIG. 2 ). While the interference set 120 itself can be operated such as shown inFIG. 3 , such as to emulate one or more devices, the interference test system 100, such as seen inFIG. 4 , can be configured to separately introduce wireless traffic from other sources, such as fromother devices 20, access points 18, and/orbridges 22, either to communicate with theDUT 110, or to applyinterference signals 140 within thetest region 103. - In the
test system 100 b seen inFIG. 4 , theadditional devices 20, e.g., 20 a-20 g, access points 18, e.g., 18 a-18 d, and/orbridges 22 e.g., 22 a-20 c, can be located within thetest enclosure 102, such as within shield boxes 130 (FIG. 3 ), or can be located externally to thetest enclosure 102, with antennas, e.g., 138 extending into the test region 103 (FIG. 3 ). - The illustrative
additional device 20 seen inFIG. 4 can be controlled by adevice controller 132 and monitored by adevice monitor 134, and can be used to provide one or more wireless signals 66 within thetest region 103, such as for any of communicating with theDUT 110, applyinginterference signals 140 within thetest region 103, or for tracking interference at thedevice 20 that may be caused by operation of theDUT 110. - The
illustrative test system 100 b seen inFIG. 4 can also include an access point (AP) 18, such as controlled by aAP controller 142 and monitored by aAP monitor 144. Theillustrative test system 100 b seen inFIG. 4 can also include awireless bridge 22, such as controlled by abridge controller 152 and monitored by abridge monitor 154. Theaccess point 18 and/or thebridge 22 can be configured for communication with theDUT 110, and/or can be configured for configured with the interference set 120, thedevice 20, and/or with each other. -
FIG. 5 is a schematic diagram of an illustrative embodiment of a further dynamic interference test setup system 100, e.g., 100 c, which can emulate traffic from high-density environments offices 12, and which can include a multitude of Wi-Fi devices, e.g., 18,20,22 and non-Wi-Fi devices, e.g., 74 (FIG. 2 ). Theillustrative test system 100 c seen inFIG. 5 can include one or more devices undertest 110, e.g., 110 a-110 e, one or more interference sets 120, e.g., 120 a-120 f, one or moreother devices 20, e.g., 20 a-20 g, one ormore access points 18, e.g., 18 a-18 d, and one ormore bridges 22, e.g., 22 a-22 c. - In some embodiments of the interference test system 100, such as seen in
FIGS. 3-5 , the interference sets 120 can integrate the transmission and/or reception of wireless signals 66 contributed by theother devices 20, access points 18, and/or bridges 22. For example, wireless signals corresponding to one ormore devices test region 103 though one or more antennas 138, e.g., 138 a-138 d (FIG. 5 ) operating on one or more bands. - The illustrative test systems seen in
FIG. 4 andFIG. 5 can be implemented with atest enclosure 102 having atest region 103 defined within, which provides an environment for controlled interference testing of one ormore DUTs 110. As seen inFIG. 4 andFIG. 5 , each device under test (DUT) 110, such as anaccess point 18, abridge 22, or awireless device 20, can be powered and controlled through aDUT controller 112, under testing conditions that can include controlledinterference 140, wherein the operation of eachDUT 110 can be monitored by aDUT monitor 114. In some embodiments of the test system 100, theDUT controller 112 and the DUT monitor 114 can implemented by anintegrated controller 112 and monitor 114, which in some embodiments can be used to control and monitor additional devices undertest DUT 110. Furthermore, the control parameters and monitored performance can be captured, stored and/or displayed, such as for analysis by testing personnel U. - The interactive dynamic interference test setup system 100, e.g., 100 a-100 c can be used to develop, operate, evaluate and modify the hardware and/or operating parameters of
wireless devices operating environments subsequent devices 110, i.e., production units, can be configured and/or updated to meet and/or exceed performance specifications. - The illustrative interference test systems 100 a-100 c seen in
FIGS. 3-5 can be configured to run different types of traffic on one or more interference sets 120, and can control the power level of appliedinterference 140. The illustrative interference systems 100 a-100 c can also control the attenuation between access points (AP) 18 andclient devices 20, while monitoring the performance of one or more devices under test (DUTs) 110. In some embodiments, the test system 100 can implement interference by creating multiple sets of access points (APs) 18 and bridges 22 on various channels, and then running traffic between eachAP 18 andbridge 22. EachAP 18 andbridge 22 can be located in a shield box 130 (FIG. 3 ) such as within thetest chamber 102 or located externally to thetest chamber 102 and connected to acorresponding antenna structure 136. The test system 100 can independently manage eachset 120, such as to emulatecrowded network environment - The interference test system 100, e.g., 100 a-100 c, can control attenuation between the
shield box 130 and theDUT 110, such as to control the simulated distance of wireless signals 66 that correspond to aninterference set 120 and theDUT 110. The interference test system 100 can also control attenuation between theDUT 110 and anuplink side 70 of awireless link 66, to test and evaluate DUT performance for clients at different distances, and can run full rate vs. range (RvR) testing on theDUT 110, to evaluate the effect ofinterference 140. - The interference test system 100 can also check the dynamic behavior of the
DUT 110. For instance, the system 100 can injectinterference signals 140, e.g., 66,72,74,80 for a duration, after which time theinterference 140 is removed, wherein it can be determined how theDUT 110 recovers from the interference event. - In some embodiments, different modulation and coding schemes (MCS) can be run with applied
interference 140, to simulate different types of clients and different distances, to determine the effects. In some embodiments, the test system 100 can also measure other parameters such as packet error rate (PER) and/or delay, to see how theDUT 110 behaves in different interference scenarios. - As noted above, a wide variety of supplementary devices often operate in
different environments other devices microwave ovens 74 are commonly used in a home or office environment, on an as needed basis. During operation, which can include one or more modes, spurious signals from such a supplementary device can adversely affect the transmission and/or reception of communication packets betweendevices - Therefore, some embodiments of the interference testing system 100 provide a wide variety of different interference scenarios with which a device can be tested. As well, the some embodiments of the interference testing system 100 provide a wide variety of methods by which a device under test (DUT) 110 can be adjusted or altered in function, to test how the device functions, to determine whether the communication performance of the

Theillustrative method 700 seen inFIG. 10 shows thedetermination 702 of desired dynamic operating parameters for such a wireless device, such as based on the intended use of aDUT 110, or based on the results of prior interference testing. The dynamic operating parameters for theDUT 110 are established or updated 704, such as through interaction with theDUT processor 604 throughport 618 and/or through interface 620 (FIG. 9 ).

The system 100 andmethod 300 can also control attenuation between theDUT 110 and opposite side of awireless link 66, to test and evaluate DUT performance forclient devices 20 at different distances, and can run full rate vs. range (RvR) testing on theDUT 110, to evaluate the effect ofinterference 140. - The interference test system 100 and
corresponding methods DUT 110.

interference 140, to simulate different types ofclient devices 20 and different distances, to determine the effects. The interference test system 100 andcorresponding methods DUT 110 behaves indifferent interference scenarios 140. - As seen in
FIG. 4 andFIG. 5 , one or moreother devices 20 can be operated with thetest environment 102, such as to function as part of an interference environment, or to be tested as devices undertest 110.Such devices 20 can include any of Wi-Fi devices, and/or non-Wi-Fi devices, such as cordless phones, Bluetooth devices, baby monitors, devices operating in cellular bands, appliances, computers, printers, radio-controlled devices, and/or tools. For instance, 2.4 GHz or 5 GHz base stations or cordless phones or remote controllers are common devices that can readily be operated or tested with the interference test system 100 andcorresponding methods - In some system embodiments 100, the interference sets 120 can be configured to generate signals for one or more devices in a simulated wireless environment. As well, in some system embodiments 100, the interference sets 120 can be configured to incorporate signals from actual devices that operate over different operating modes, e.g., microwave ovens and/or baby monitors. For instance, different modes of baby monitor operation, such as stand-by, voice-activated output signals, system test, music modes, and/or voice return signals can be incorporated within a suite of
testing modes 306. Similarly, different modes of microwave oven operations can be tested, such as to coincide with oven used during typical hours, such as lunch time (e.g., 11:30 AM to 1:30 PM, dinner time (e.g., 5:00 PM to 7:00 PM), snack times (e.g., 2:00 PM to 3:30 PM and 8:00 PM to 11:00 PM), etc. - Some embodiments of the interference test system 100 and

In this manner, some embodiments of the interference test system 100 andcorresponding methods DUT 110, such that in situ intelligence can be established for a device to be implemented in a real-world environment local device wireless environment - During and as a result of interference testing 300,700,800, the interference test system can readily be used to provide dynamic adjustment for a device under
test 110, such as to establishdynamic operation parameters 608 for aproduction device world interference environment -
FIG. 12 is a flowchart of an illustrative method for dynamically modifying the operating parameters of a wireless, i.e.,WLAN device 600, e.g., 18,20,22,110, based on the detection of interference conditions. For instance, awireless device 600 can be configured to begin upon power up to operate in awireless environment preset communication parameters 608. In a typical embodiment, anaccess point 18,bridge 22 orother wireless device settings 608, such as settings that were established during initial installation of thedevice 600. - Upon
startup 902 usingdefault operation parameters 608, theprocessor 604 associated with thewireless device 600 can determine or detect 904local interference conditions 140 that limit wireless reception and/or transmission of wireless signals 66. Theillustrative device 600 can also determine 906 if the current interference conditions are substantial enough, such as compared to one or more predetermined thresholds, to require dynamically adjusting or modifying 914 one ormore operating parameters 608 of thedevice 600. If not, 908, thedevice 600 can continue 910 to operate using previously established operation parameters. If the current interference conditions are determined 906 to be substantial 912, thedevice 600 can be configured to modify 914 one ormore operation parameters 608, and then operate 916 thedevice 600 using the modifiedparameters 608, after which time thedevice 600 is configured to return 918 to thedetermination 906 of the current interference conditions. Duringsubsequent operation 916, if it is determined 904,906 that the local interference has increased, decreased, or otherwise changed, thedevice 600, as controlled by theprocessor 604 andparameters 608, can again modify thedynamic operating parameters 608, such as to optimizewireless communication 66 under the changinginterference conditions 140. - The
dynamic adjustment 916 of operatingparameters 608 can be used to increase and/or optimize the performance of aproduction device office environment production device environment - For example, many wireless devices that generally comply with enhanced distributed channel access (EDCA) 802.11 standards do not have good receivers, and as such, do not adequately detect other packets in densely populated areas. Standard EDCA operation can often result in extremely large back offs. As well, commonly used rate control can result in low rates, larger packets, and decreased performance.
- The assumption that
neighboring devices 20 behave according to 802.11 specification is often not valid due to several reasons, such as due to poor 802.11 implementation, standards other than 802.11, or the use of modified 802.11 procedures. - As a result of testing of
DUTs 110 in controlled anduncontrolled interference environment 102 provided by the interference test system 100 andcorresponding methods production device - While the system 100 and
methods methods dynamic operating parameters 608 that revert back to common settings, such as when there is little or no interference. - As discussed above, some 802.11 devices do not fully or partially implement 802.11 EDCA and are not “fair” in how they operate in a shard environment. As well, some 802.11
devices 20 do not have good receivers, and do not hear other communication packets in denselypopulated area wireless environment - While some software and hardware solutions are currently available for wireless devices that operate in a wireless local area network (WLAN), which allow some settings for such wireless devices to be changed to improve performance, the interference system 100 and
corresponding methods corresponding methods - Enhanced Interference Detection.
- While the duty cycle for a WLAN device includes a basic service set (BSS) for operating within an environment that can include both Wi-Fi and non Wi-Fi traffic, some embodiments of the interference test system 100 and
corresponding methods interference 140. For instance, the detection of long back offs without successful packet transition, or the tracking of the number of successful packet transmissions, when there isinterference 140, can be used to detect interference. In some embodiments, the scanning channels on the same band or an adjacent band can be used to detect thecurrent interference conditions 140. - Implementation of Receiving (Rx) Solutions.
- In some embodiments implemented using the interference test system and
corresponding methods processor 604 of awireless device 600 can include instructions to detect the destination address in MAC header field of a receivedwireless signal 66, e.g., adownlink signal 68 or anuplink signal 70, and use the detected destination address, inheavy interference environment signal 66, which may arrive at the middle of another competing signal in theinterference environment - For some wireless protocols (e.g., IEEE 802.11), the
device 600 andprocessor 604 are configured to detect request to send (RTS) and/or clear to send (CTS) mechanisms of packets for awireless signal 66 that are not of interest, and as a result of such a detection, either not listening to whole exchange, or keeping the local receiver (e.g., transceiver 610 (FIG. 9 )) in detection mode, for packets that thelocal device 600 is interested in. - In some embodiments, the
device 600 andprocessor 604 can be configured to configured to dynamically detectrogue access points 18 that receive significantly more communication packets than thelocal device 600, and then ignore thoseaccess points 18, either completely or partially, when applicable. For instance, anaccess point 18 can be considered to be rogue when it receives more than a detected percentage (e.g., X percent) of a local wireless medium, while thelocal device 600 receives no more than Y percentage of the local wireless medium. - In some embodiments, the
device 600 andprocessor 604 can be configured to configured to detect the local operation of non Wi-Fi devices 20, such as operating as unlicensed spectrum (e.g., LTE-U) in alocal wireless environment device 600 gets more airtime than the local non wi-fi device, e.g., 20, or unless the neighboring non wi-fi device 20 gets more airtime than a predetermined percentage of thelocal device 600. - In some embodiments, the
wireless device 600 andprocessor 604 can be configured to configured to make packets of clients smaller in size, when the WLAN device is anaccess point 18 or a link owner, such as by deleting a block acknowledgement (BA) agreement, and making new BA agreement having a shorter receive BA window size. In such a scenario, the BA receiver window size can dynamically be changed during association, such as when a client receive signal strength indicator (RSSI) is higher than a threshold and the uplink or downlink traffic is low, or when a client queue is larger than a predetermined threshold. - In some embodiments, the
WLAN device 600 andprocessor 604 can be configured to configured to drop the acknowledge (ACK) rate of the client, whenWLAN device 600 is anaccess point 18. - In some embodiments, the
WLAN device 600 andprocessor 604 can be configured to configured to de-authorize aclient device 20, and the reauthorize back. In some such embodiments, this is done only when client receive signal strength indicator RSSI is higher than a predetermined threshold, and the uplink or downlink traffic is low, or when a client queue is determined to be larger than a predetermined threshold. - Implementation of Transmission (Tx) Solutions.
- In addition to dynamic interference detection and enhanced reception for a
WLAN 600 that operates in awireless environment WLAN device 600 andprocessor 604 can be configured to alter the transmission properties of thelocal device 600 as a dynamic response to changinginterference conditions 140. The specific dynamic response can be based on whether theWLAN device 600 operates as anaccess point 18, as awireless bridge 22, or as another type ofwireless device 20. - For instance, in some embodiments, the
WLAN device 600 can be configured to change its rate control mechanism in response to detectedinterference 140, such as by changing the rate control based on a different algorithm when operating underhigh interference conditions 140, as compared to an algorithm that is used under low or non-interference conditions. In some embodiments, theWLAN device 600 is configured to drop the rate when packet error rate (PER) is higher than a predetermined threshold, as compared non-interference scenario. - In wireless operating environments, use of the higher modulation and coding schemes (MCS) requires very good signal-to-noise (SNR) modulation, while the use of lower MCS can result in longer communication packets too long, which increases the chance of collisions, resulting in signal loss. As such, some embodiments, the local device are configured to limit the use of highest and lowest MCS.
- In some embodiments, the local device is configured to dynamically compare the packet error rate (PER) of higher and lower modulation and coding schemes (MCS), wherein if the lower MCS results in a higher packet error rate (PER), the local device is configured to use the higher MCS.
- In some embodiments, the local device can be configured to dynamically increase retries, and/or decrease the size of communication packets, when increased interference is detected.
- As well, some embodiments, the local device can be configured to dynamically drop the data rate of acknowledgement (ACK) frames when helpful. ACK frames are typically short packets, having headers that make up a substantially large percentage of the length of the packet. As such, dynamically lowering lower the rate of acknowledgement (ACK) frames can improve the net throughput of the local device in some
high interference environments - In some embodiments, the local device can be configured to dynamically modify enhanced distributed channel access (EDCA) 802.11 parameters, such as when rogue interference from
rogue access points 22 is detected, and/or when thelocal wireless environment - In some embodiments, the local device can be configured to dynamically modify operation when a determined interference duty cycle is larger than a predetermined percentage, such as by not using aggregated MAC service data units (AMSDU).
- In some embodiments, the
local WLAN device 600 can be configured to dynamically react to specific interference conditions, such as when one or more rogue access points (APs) 18 are detected that do not back off, or when the duty cycle of an interfering device is high. Upon the detection of such dynamic conditions, the local device can be configured to not use request to send (RTS) and/or clear to send (CTS) mechanisms that would otherwise be used under low interference conditions, and can proceed to send data packets as soon as it is possible to do so. - In some embodiments, the
WLAN device 600 can be configured to take other actions in response to detectedheavy interference conditions 140, such as by refraining from beamforming under conditions in which beamforming training cannot be done correctly, or when or beamforming training does not happen successfully, due to collisions. Other actions that can be configured by theWLAN device 600 under high interference conditions can include refraining from Multiple Input-Multiple Output (MIMO) transmission, or decreasing an allowed number of multi-users (MU). -
