Patent ID: 7076253

Claim:
A wireless mobile unit comprising: a signal strength indicator configured to detect when the wireless mobile unit is in a high data rate, code division multiple access (CDMA) area by determining whether a strength of a high data rate carrier signal broadcast by a base station exceeds a predetermined level; a processor being configured to determine a need for exchanging data between said wireless mobile unit and the base station; and a data burst optimizer configured to automatically exchange said data between said wireless mobile unit and said base station at a high data rate using code division multiple access when (a) the signal strength indicator detects said wireless mobile unit is in said high data rate, code division multiple access area, and (b) the processor determines a need for exchanging data between the wireless mobile unit and the base station, wherein said processor invokes said data burst optimizer to automatically exchange said data between said wireless mobile unit and said base station when said wireless mobile unit is in said high data rate CDMA area and when said processor determines said need to exchange said data between said wireless mobile unit and said base station, and wherein said data burst optimizer transmits a logon name and password to said base station to authenticate said wireless mobile unit.
