Abstract: Implementations of the present disclosure relate to a short detection and protection circuit for an access point. The circuit comprises a plurality of front end modules (FEMs), a power source configured to supply power to the plurality of FEMs, a plurality of first switches electrically connected between the plurality of FEMs and the power source, and a plurality of short detection units each electrically connected to a respective FEM of the plurality of FEMs and a respective first switch of the plurality of first switches. With these implementations, by providing the short detection units of the present disclosure, the common power source is electrically isolated in time from the failed or shorted FEM, and the common power source can continue to supply power to other FEMs of good performance. Thus, the access point (AP) can keep working, thereby improving the reliability of the AP.

Abstract: Examples described herein provide selective filtering by a network device for continuous 5 GHz and 6 GHz operation. Examples may include receiving, by the network device, a first signal in a 5 GHz band, and generating, by the network device, a second signal in a 6 GHz band. Examples may include selecting, by the network device, a first filter or a second filter to be applied the first signal in the 5 GHz band, wherein the first filter allows a lower frequency band to pass than the second filter in the 5 GHz band, selecting, by the network device, a third filter or a fourth filter to be applied to the second signal in the 6 GHz band, wherein the third filter allows a lower frequency band to pass than the fourth filter in the 6 GHz band, and simultaneously applying, by the network device, the selected first or second filter to the first signal and the selected third or fourth filter to the second signal.

Abstract: In implementations of the present disclosure, there is provided an approach for reducing interference between channels of a wireless wide area network (WWAN) and channels of a wireless local area network (WLAN). A method comprises determining a first working channel in a first frequency band of a WWAN, and selecting a first filter from a first set of filters corresponding to the first frequency band based on the first working channel. Then, a second filter from a second set of filters corresponding to a second frequency band in a WLAN and a second working channel in the second frequency band are selected. The determined first working channel and the selected second working channel are used to transmit data. Implementations of the present disclosure can help the terminal device to use channels of WWAN and WLAN simultaneously and reduce interference between channels of WWAN and WLAN.

Abstract: Implementations of the present disclosure relate to a system comprising an access point (AP), an antenna module and a radio cable. The AP includes a modulator configured to receive a clock signal and a power voltage and modulate them into a modulated power. The radio cable is configured to transmit the modulated power. The antenna module comprises a directional antenna, a demodulator configured to demodulate the modulated power into a demodulated clock signal, and a sensor configured to receive the demodulated clock signal and the modulated power. With the system of the present disclosure, the compass/declinometer sensors can be deployed on the panel antenna, so as to obtain the location, the direction and the coverage of the panel antenna. Further, the radio frequency cables can be used to transmit the power and clock signal between the sensor and the AP, and there is no need to provide dedicated cables.

Abstract: In implementations of the present disclosure, there is provided an access point (AP) radio arrangement for Wi-Fi. A method comprises selecting a filter for a first antenna from a first set of filters. The method further comprises determining a subset from a second set of filters based on the selected filter. The method further comprises selecting a filter for a second antenna from the subset. Implementations of the present disclosure can make full use of 6 GHz channels, and the combinations for dual 6 GHz usage scenarios can be more flexible.

Abstract: Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.
