Abstract

Methods and apparatus for providing wireless data or voice coverage in a region by employing existing poles as part of a distribution network. Base station equipment is placed in a co-location facility, and then the BTS
signals are distributed over a communication network to remote pole locations, where the signal is radiated from antennas mounted on the poles. This coverage can employ various current and future standards, including cellular standards such as GSM, CDMA, and UMTS, and IP data standards such as 802.11a and 802.11b.
