Abstract
A method and apparatus for synchronized hand off from a cellular network (138) to a wireless network (100) includes an antenna (110) capable of receiving a synchronization channel and a pilot channel (112). Within the wireless network (100) is an access point (104) and a cellular timing recovery receiver (106) coupled to the antenna (110). The cellular timing recovery receiver (106) receives the synchronization channel and the pilot channel (112), which are provided to the access point (104) from a cellular base station (114). The cellular timing recovery receiver (106) thereupon generates a clock pulse (120) and a clock setting signal (122) which are provided to the access point (104), which are utilized to synchronize an internal clock with respect to the timing of the cellular base station (114). Thereupon, the wireless area network (100) may be synchronized with a cellular network (138) message information (150c).
