A device for optimizing model performance includes: a memory resource storing a local model on an electronic device; and a first processor. The local model is obtained by use of a machine learning process. The first processor: obtains data at the electronic device; applies the local model to the data or further data derived from the data to obtain at least one local model result; generates a measure of the quality of the local model result, and sends the data, further data derived from the data and/or the local model result through a communication device to a second processor for use in updating a global model based on the measure of the quality of the local model result.

Device and method for optimising model performance

An IEEE 802.11 compatible processor configured to identify, using an indication received from a first station in a network and from among a plurality of further stations within the network, a second station to transmit data to during receipt of a next transmission from the first station using information indicating which stations amongst the further stations data can be transmitted to while receiving data from the first station; and information regarding the duration required to transmit next data scheduled to be transmitted to the second station, wherein the indication is an indication of the duration of the next data transmission scheduled to be transmitted by the first station.

Simultaneous transmit and receive operation in WLANs

A WiFi system comprising two or more access points operating in the same network and a plurality of nodes. Each node is in communicative association with each access point. A plurality of nodes transmits data in a scheduled communication with a first access point of the two or more access points and subsequently re-transmits some or all of the data in a scheduled communication with a second access point of the two or more access points.

Reliable and deterministic Wi-Fi for industrial control applications

Management of receiver sensitivity in a packet based wireless communication system is achieved by controlling a clear channel sensing process which determines if the channel is clear for use, governed by a sensitivity to use of the channel. The sensitivity of the clear channel sensing process is effected by monitoring transmission performance over a plurality of emissions, and making adjustments to the sensitivity based on comparison of that performance with a performance criterion.

Wireless communications device and method

A device and method for wirelessly communicating over a transmission channel with one or more wireless devices. The device comprises a wireless network interface and a controller. The controller is configured to receive a wireless signal via the wireless network interface, if strength of the received signal is greater than a first threshold, determine that the channel is busy, and, if the strength of the received signal is not greater than the first threshold, but is greater than a second threshold that is lower than the first threshold, determine whether the received signal is intended for the device and if so, determine that the channel is busy.

Multi-threshold listening method for dynamic sensitivity control enabled wireless MAC

A device and/or method for dynamically adjusting a CCA threshold in an addressable unit that is suitable for communication in a wireless network, the method performed in the addressable unit and comprising autonomously increasing the CCA threshold with successful data transmissions and/or autonomously decreasing the CCA threshold with unsuccessful data transmissions.

Dynamic sensitivity control in 802.11 stations

Certain embodiments provide a system comprising a plurality of Femtocell base stations in communicative contact with each other, in use, via a control channel. The Femtocell base stations arranged to exchange information suitable for controlling a said Femtocell base station via said control channel.

Radio resource management in Femtocells

Certain embodiments provide a Femtocell base station arranged to receive interference notifications from another Femtocell base station and to send an interference remedial command to the other Femtocell base station and/or to one or more further Femtocell base stations.

Radio resource management in femtocells

An arrangement for wireless communication includes apparatus operable to establish a region of wireless communications capability, and operable to establish communication with a communications hub by way of a backhaul. The apparatus is operable to determine availability of communication facilities on the backhaul and, in response to a request by a communications device operating with the use of the region of wireless communications capability, is operable to offer the backhaul implemented communication facilities to the communications device subject to the existence of a fault in offering of said facilities. The apparatus includes fault detection means operable to detect the presence of a fault. In the event of a fault being detected, the apparatus is operable to emit a signal intended to communicate the existence of the fault to t communications device.
