Tower Sharing
Knowledgeportalcfn
Telecom operators have realized the value of sharing infrastructure and in the last few years, to maintain profitability. The Department of Telecom has allowed passive infrastructure sharing among operators, which includes sharing of physical sites, buildings, shelters, towers, power supply and bat-tery backup. In early 2008, it also allowed sharing of active infrastructure but it has been limited to antenna, feeder cable, node B, radio access network and transmission systems and not sharing of spectrum. With sharing, the cost burden on operators reduces significantly, improving the rate of mobile services rollout.
