Abstract
A slave low power radio frequency transceiver participates in a network controlled by a master low power radio frequency transceiver and synchronises its timing to the network timing by receiving radio packets transmitted from the controlling low power radio frequency transceiver. The slave transceiver comprises timing means; detection means operable over an interval of time for detecting a predetermined portion of a received radio packet; and adjusting means for adjusting the timing means in response to the detection of a predetermined portion of a received radio packet. The slave low power radio frequency transceiver is arranged to controllably vary the duration of the interval of time.
