摘要
A novel mechanism for avoiding RF collisions using frequency synchronization techniques. In one embodiment, a solution to the problem comprises dividing the channel map into different channel groups wherein each group includes a minimum number of channels. The composition of the channel groups depends on the number of piconets and the number of good and bad available channels. Thus, collisions are avoided by assigned each piconet a channel group where the channels in one group do not overlap the channels in other groups. As the channel map changes over time, the channel groups are dynamically updated with the new good and bad channels. In a second embodiment, all the neighboring piconets are configured to use the same channel sequence order. Each piconet, however, is assigned a different starting frequency (i.e. channel). Thus, collisions are avoided since at any instance in time, no two piconets are using the same channel.
