Abstract: Systems and methods for improving wireless access point communications are provided. Some embodiments contemplate filtering operations such that two or more radios can be used in the 5 GHz or 2.4 GHz band without interfering with each other. Some embodiments employ discrete Low Noise Amplifiers (LNA) and Power Amplifiers (PA) as well as frontend modules. In some examples, filtering may be primarily used on the receiving side to filter out other signals in 5 GHz before they are amplified by an external LNA or LNAs, e.g., as integrated in a WLAN chipset. Filtering may also be performed on the transmit side in some embodiments.

Abstract: The disclosed embodiments include a method performed by a cloud system for changing a registration of a network access device. The method includes initiating a change of a registration of a network access device.

The physical reset allows the first user to dissociate the ownership of the network access device. The method further includes, upon receiving both the authorization by the first user and the indication of the physical reset, releasing the ownership by the first user of the network access device at the cloud system.

Abstract: Techniques are disclosed for reducing interference, in a network device, among multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, a network device includes a first and a second wireless network circuit. The network circuits operate in a same radio frequency band and are collocated.

Abstract: A radio frequency front end module is provided for a high power capability and a high signal band selectivity. The front end module includes an external filter and an integrated circuit coupled with the external filter via two external filter leads. The integrated circuit includes a transmit-receive switch, a power amplifier and a low noise amplifier. The transmit-receive switch alternates between coupling an antenna port to a transmit port and coupling the antenna port to a receive port. The power amplifier amplifies a modulated radio frequency signal. The low noise amplifier amplifies a received radio frequency signal when the antenna port is coupled to the receive port. The external filter can be replaced to adapt to various requirements of signal frequency bands, without the need of modifying the layout of the integrated circuit.

Abstract: Various of the disclosed embodiments improve the operations of a combined access point/Cable modem. Though the access point component and the Cable modem component may perform operations in different spectrums, harmonics in the Cable spectrum may interfere with operations, e.g., in the 2.4 GHz and 5 GHz range, of the access point. Some embodiments implement a remediation and/or channel transition process for the access point following detection of Cable-related interference. During remediation, the device may, e.g., adjust the wireless power levels, EDCA backoff times, signal thresholds, etc. In some embodiments, if the remediation actions prove ineffective, the wireless peers may be relocated to a channel further from the interfering Cable harmonics. The determination to remediate or reallocate may be based on various contextual factors, e.g., the character of the peer devices and the applications being run.

A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network.
