The maximum range of a mast (where it is not limited by interference with other masts nearby) depends on the same considerations.In any case the limiting factor is the ability of a low - powered personal cell phone to transmit back to the mast. As a rough guide, based on a tall mast and flat terrain, it may be possible to get between 50 and 70 km (30 -- 45 miles). When the terrain is hilly, the maximum distance can vary from as little as 5 kilometres (3.1 mi) to 8 kilometres (5.0 mi) due to encroachment of intermediate objects into the wide center fresnel zone of the signal. Depending on terrain and other circumstances, a GSM Tower can replace between 2 and 50 miles (80 km) of cabling for fixed wireless networks. In addition, some technologies, such as GSM, have an additional absolute maximum range of 35 kilometres (22 mi), which is imposed by technical limitations. CDMA and IDEN have no such limit defined by timing.
