Abstract
A device and method for connecting to a WiMAX network can determine an initial signal strength as a function of an uplink propagation path loss between a mobile device and a base station, a noise and interference level value for the base station, a normalized carrier-to-noise value for ranging, and an offset value. If a connection is not established at the initial signal strength, a signal can be retransmitted at a signal strength equal to the initial signal strength plus a step value, where the step value can be determined by designating a fixed number of steps to be used before reaching maximum transmission power.
