Robust communication system

A primary station ( 10 ) for use in a communication system is described, the system operating according to a predetermined protocol. The primary station is capable of managing a plurality of piconets having secondary stations ( 12 a, b, c) which communicate with the primary station on individual logical radio channels. In particular, the capacity available on the channels is monitored ( 20,25 ) and the channels in use controlled thereby enabling the secondary stations to communicate even in periods of heavy use. The primary station is suitable for application as a wireless access point in public spaces (airports, train stations) and in business or home scenarios where robust low power multiple radio networks are required.
