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 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 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.
