Apparatus and method for handing over, at a time instance, a first low power radio frequency transceiver participating in a first network of low power radio frequency transceivers using first network parameter(s) and controlled by a first master transceiver from the first network to a second network of low power radio frequency transceivers using second network parameter(s) and controlled by a second master transceiver. An indication of the time instance is sent to the first low power radio frequency transceiver. An indication of the time instance is also sent to the second master transceiver. An indication of the second network parameter(s) is sent to the first low power radio frequency transceiver. The first transceiver switches from using the first network parameter(s) to using the second network parameter(s) at time the time instance. The second master transceiver polls the first transceiver at the time instance using the second network parameters.
