Resource sharing is in place in few other countries, but a system like this one is probably the first time in the world.
6 telecom giants are sharing the same tower - Airtel, Hutch, Idea, MTNL, Tata Tele Sevices and Reliance. The tower has 12 GSM, 6 CDMA and 6 Microwave antennas all working absolutely fine. This special tower is designed and certified by
