<p>A hub unit (401) and satellite unit (402) are located in or near proposed locations for first and second devices of the wireless network. A first signal is transmitted on a channel of the wireless network from the hub unit (401) to the satellite unit (402) and a first test is performed on the first signal at the satellite unit (402). Results of the first test may be transmitted to the hub unit (401). It is then determined from the results of the first test (and second test, if present) whether the proposed locations of the first and second devices of the wireless network are suitable. The wireless network may be an IEEE standard 802.15.4 network, for example a Zigbee (RTM) Smart Energy network. The satellites are placed in proposed locations for devices in the smart energy network, e.g. the proposed location of the gas meter. The hub unit may be placed in a proposed location for a further device for the smart energy network e.g. the proposed location of the electricity meter. Embodiments of the invention include an apparatus for use as a hub unit, an apparatus for use as a satellite unit and an apparatus for use as a router unit.</p> |
