Lack of Tetra network haunt terror-hit Mumbai

"We depended on mobile phones, our radio wireless communication system was the only back up, we had to depend on that, but our statewide VHF network is not being used now"


Wednesday's terror attacks in Mumbai not only exposed the Maharashtra government's hollow claims of being prepared after 26/11, it also heaped more shame and embarrassment on the state apparatus.

Chief minister Prithviraj Chavan was forced to admit that he and several other senior officials could not communicate with each other as phone lines got jammed across the city. It wasn't the first time that Mumbai's communication systems let down a megapolis already reeling under a terror onslaught.

Chavan was left completely helpless in the initial moments after the bombs went off. "But for the first 15 minutes or so, there was complete breakdown of communications which was shocking, which was unacceptable. We depended on mobile phones, our radio wireless communication system was the only back up, we had to depend on that, but our statewide VHF network is not being used now. We're trying to rebuild that as a back up communication," he told a TV channel.

The situation would have been different if Mumbai had taken to its logical end the Brihanmumbai Municipal Corporation's (BMC) 2007 plans to install a Tetra (terrestrial trunked radio) network for the entire city. An uninterrupted communication network, a key component of a robust emergency response system, is known to be a life-saver in moments of crisis the world over.

Soon after the deluge of 2005, the BMC started discussions on creating a communication network that could mesh the police, fire department and other emergency responders on a single system, which can withstand all calamities. Though the first tender was floated in 2007, four years later there is no sign of the network. Delhi, which started the process much later, installed its Tetra network before the 2010 Commonwealth Games.

The result of the Maharashtra government's lackadaisical attitude has been that emergency responders were left at the mercy of phone lines and jammed mobile networks to coordinate during the critical initial moments of a terrorist strike.

In 2008, when 10 terrorists struck Mumbai, the total lack of a cohesive and secure communication network was acutely on display. Some observers also believe that it might have even led to the loss of some more lives. Many key functionaries, including chiefs of agencies involved in the operations in 2008, were dependent on insecure mobile networks for communication.

Sources say the 2007 tender for the Tetra network was cancelled by the BMC after one of the competitors complained they were not given adequate time to participate. A fresh expression of interest was issued in December 2008. This tender process was again
