Abstract: The present disclosure relates to a computer-implemented method of operating a wireless network access point of a wireless network. The method includes wirelessly exchanging management frames with a device to attach the device to the access point, thereby establishing: a wireless downlink data communication channel from the access point to the device, and a wireless uplink data communication channel from the device to the access point. The method further includes performing a wireless link test comprising: transmitting a test frame to the device on the downlink channel, the test frame having a length greater than each of the management frames, including a sequence of test data bits, and being configured to require a mirror response comprising the sequence of test data bits; monitoring for receipt of the mirror response on the uplink; and, if the mirror response is received, determining the test is passed.

Abstract: Disclosed is a method of selecting a channel for wireless communication between an access point and a client device in a WLAN, the method including obtaining a first performance measurement from a first channel during a first interval, obtaining a second performance measurement from a second channel during a second interval, the first interval being temporally separated from the second interval by a predetermined period which is greater than or equal to one second, and selecting a communication channel for use taking the first and second performance measurements into account.

Abstract: In Multipath Transport Layer Protocol (MPTCP) data transmission, data packets are sent from a transmitter to a receiver over at least two data paths, for example using a cellular data connection and a wireless network data connection. An apparatus located at a common point in the data paths is used to monitor the characteristics of any data flows in a MPTCP connection and to manipulate the packet characteristics of the data flows to ensure the MPTCP performance matches a predetermined data distribution target.

Abstract: Wireless access point devices having wireless networks operating in accordance with 802.11b/g 2.4 Ghz Wi-Fi can be affected by out-of-band interference caused by LTE small cell devices such as macrocells and femtocells. The wireless access points detect such interference devices using a flow processor to monitor the characteristics of data flows of devices connected to the wireless access point to determine whether they are LTE cells based on MAC address matching or the termination of a flow at a known mobile network operator gateway. When a cell is detected, the wireless access point scans for neighboring wireless networks of neighboring wireless access points which may also be affected by the interference generated by the LTE cell. A management server processes information relating the LTE cell and the neighboring wireless networks and generates a mitigation action to change the operational behavior of the wireless access point and any neighboring wireless access points to mitigate the effect of the detected interference device on the wireless networks.

Abstract: There is herein disclosed a method of measuring the performance of a first communication channel at a first access point in a WLAN, in which the first access point is associated to a client device so that the first access point can send data to, and/or receive data from, the client device on a second communication channel, the method including disassociating the first access point to the client device and associating a second access point to the client device; switching the working channel of the first access point from the second communication channel to the first communication channel; and making one or more performance measurements in respect of the first communication channel at the first access point.

Abstract: A wireless router having a WiFi wireless network and including a small cell for routing LTE cellular data to a mobile network core is configured to monitor connected mobile devices and determine whether each mobile device should be connect to the hub using WiFi or LTE in accordance with the current utilization of the WiFi network and the current utilization of the LTE small cell. Since the small cell data traffic transmitted in a data tunnel to the mobile network core is accessible to the monitor, the network identity information of the device's WiFi interface and the device's LTE interface can be determined by consulting an address mapping store in the cellular mobile network core. Furthermore presence information can be determined by detecting connection and disconnection messages between the mobile device and cellular network core.

Abstract: A management server for managing a population of wireless access point devices by detecting out-of-band interference to the operation of the wireless access point Wi-Fi networks caused by LTE small cell devices such as macrocells and femtocells. A flow processor monitors the characteristics of data flows of devices connected to the wireless access point to determine whether they are LTE cells based on MAC address matching or the termination of a flow at a known mobile network operator gateway. A mitigation action to change the operational behavior of the wireless access point is then generated and applied to mitigate the effect of the detected interference device on the Wi-Fi network. The management server further determines, using a data store containing the location of the wireless access points, whether other wireless access points will be affected by the presence of the interference device and sends mitigation actions to potentially affected devices.
