Abstract
A wireless network is initialized by communications between mobile units forming an ad hoc network or by communications between a mobile unit and an access point unit. Mobile units transmit announcements in order to establish a communication link. To ensure the announcements are received, the mobile units scan different frequencies at various times using various hop sequences. Once communication is established, one mobile unit adopts the hop frequency of the other mobile unit according to a comparison between the hop frequencies of the two units. Multiple mobile units initialize to form ad hoc networks in similar manner.
