GSM Cell Sites have undergone a massive upgrade since the time 2G networks were rolled-out. The up-gradation have happened on all fronts including the real estate requirement, the electrical power distribution requirements, power backup requirements, etc. Infrastructure specifications have been driven by commercial considerations rather than regulatory requirements.

The Base band equipment’s are getting compacted due to smaller form factors being used and site sharing also has increased the cell site infrastructure demands.
