3G is going to come in two different flavours Firstly, existing operators with 2G or 2.5G technology are going to upgrade to 3G. Secondly, many new operators and some foreign players are also going to enter the market with 3G. Secondly, many new operators and some foreign players are also going to enter the market with 3G.

Upgrade from 2G to 3G 

The biggest piece is their whole network, the network and bandwidth that they have to upgrade. For instance, if we announce a relationship with Bharti for their 78,000-km fibre optic network. As you rollout networks, you need to get the most out of them. It has to be optimal and offer very high efficiency and integrity.



As different devices connect to the network, you need to know what they are since security is a major issue. When you have a network of that huge length, knowing everything that connects to the network is a very expensive task. We have built technology,that helps you know what’s on your network. All this translates to better customer service.
