With CSFB, the network can transfer customers to GSM platform to make and receive voice calls and access voicemails while retaining the experience of ultra-fast data services on 4G smartphones.

Nokia Siemens Networks has deployed its radio network elements in addition to its voice core and packet core network elements to the commercially launched network of Bharti Airtel in Pune.

I read in newspaper that Airtel will launch their LTE services in Chandigarh by March end and for the same contract has being given to ZTE. So, Chandigarh is ready to be first city in Northern India to get LTE services.

Waiting for 700MHz spectrum. But i have heard that it is going to be too costly, however operators can join to form a new brand and purchase spectrum jointly.
Like in UK, T-mobile and Orange together formed a new 4G network named- Everything Everywhere even though they are separately operating in 2G and 3G networks

Here in india, Airtel+Vodafone+Idea can form a new 4G brand if its too costly for them to purchase independently. Similarly, Aircel and Docomo can form their new brand
