A method of managing the transmission of unicast packets in a wireless local area network to client devices that are sensitive to collisions from transmissions to other client devices. These client devices that are sensitive to collisions, termed collision sensitive nodes, are typically associated with a problem access point, which are access points that share a coverage area with another access point but are not themselves in direct communication range of each other. A collision sensitive node is paired with each client device that is associated with the other access point to generate a respective collision node pair. Unicast packets directed to any client device in a collision node pair are scheduled to introduce a delay to their delivery so as to reduce the likelihood causing a collision at the collision sensitive node.

There is herein described, a method of Distributed Acoustic Sensing, the method comprising transmitting an optical sensing signal into an optical fibre located in a channel, measuring an intensity of a return signal, the return signal comprising a component of the optical sensing signal that has been backscattered from a target location in the optical fibre, performing a comparison of the measured intensity of the return signal to a threshold, if the comparison indicates that the intensity of the return signal is greater than the threshold, determining that a blockage may be present in the channel in the vicinity of the target location.

A method (200) of operating a wireless telecommunications system (100) comprising an ElectroMagnetic Transmitter (105), EMT, and a Rydberg-Atom Receiver (110), RAR, for detecting an EM field (170) from the EMT, and the method comprising the steps of: providing (210), to the EMT and to the RAR, a communication configuration for enabling transmission, by the EMT, of a data signal encoded within a wireless multi-band transmission, and for enabling reception, by the RAR, of said wireless multi-band transmission; configuring (220) the EMT and the RAR according to the provided communication configuration; transmitting (230), by the EMT and whilst the EMT is configured according to the communication configuration, the wireless multi-band transmission having encoded therewithin the data signal; receiving (240), by the RAR and whilst the RAR is configured according to the communication configuration, the wireless multi-band transmission; and processing the wireless multi-band transmission so as to derive the data signal.
