A multi-frequency pilot beacon adapted to a CDMA system using at least two
different carrier frequencies, F1 and F2, for supplying PN sequences at
these frequencies. The pilot beacon has a pseudorandom noise generator for
supplying a pseudorandom noise sequence PN and a frequency conversion
mechanism for converting the PN sequence to a first pilot beacon centered
at the first CDMA carrier F1 and a second pilot beacon centered at the
second CDMA carrier F2. The multi-frequency pilot beacon can be provided
at a base station of a given cell to transmit the pilot beacons within
that cell and the base station antenna can be used for transmitting the
pilot beacons in this embodiment. Alternatively, multi-frequency pilot
beacons can be provided wherever necessary within the CDMA system. The
multi-frequency pilot beacon is useful in frequency hand-off operations
and gathering information about cellular users in the CDMA system
