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: 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 positioning and synchronization of network device. A positioning and synchronization apparatus comprises an antenna. The apparatus also comprises a small form factor pluggable (SFP) connector comprising a first pin connected to a first pin of a SFP fiber port of a network device and a second pin connected to a second pin of the SFP fiber port. The apparatus also comprises a Global Navigation Satellite System (GNSS) receiver. The GNSS receiver is configured to receive signals comprising positioning-related information over the antenna and to provide a positioning signal over the first pin of the SFP connector and a pulse per second (PPS) signal over the second pin of the SFP connector.

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: Example implementations relate to changing a status of a device responsive to detecting an anomaly. A traffic pattern of a device may be monitored across a network. It may be determined that the monitored traffic pattern deviates from an expected traffic pattern of the group of devices by a threshold. Responsive to determining that the devices deviates from the expected traffic pattern, packet data transmitted by the device may be inspected. It may be determined that the inspected packet data transmitted by the device is anomalous. The status of the device may be changed responsive to determining that the packet data transmitted by the device is anomalous.

Abstract: Embodiments of the present disclosure relate to a power supply device, an electronic system and a method. The electronic system comprises an electronic device and the power supply device transmitting synchronization information from a satellite to the electronic system. The power supply device comprises a first modulator configured to receive a signal from a satellite and to generate a first modulated supply voltage, a level pattern of the first modulated supply voltage indicating synchronization information included in the satellite signal; and a first transformer configured to provide the first modulated supply voltage to an electronic device to enable a synchronization between the satellite and the electronic device based on the synchronization information. The electronic device demodulates the first modulated supply voltage to determine the synchronization information for synchronizing with the satellite. By using the embodiments of the disclosure, cost for manufacturing the electronic devices can be significantly reduced.
