Leading Indian telecom service provider Airtel has recently revealed about its plans to release 4G LTE network for the smartphones in Bangalore this month. Till now, Airtel only offered 4G LTE modems and Wi-Fi base stations. Thus the voice call facility on its 4G LTE network in Bangalore could be seen soon.
The telcom operator has adopted Circuit Switched Fall Back (CSFB) technology to provide voice calling facility over its 4G LTE networks in the country. While CSFB technology deployed within the network would enable the company to make the voice call possible to its LTE subscribers through its already existing 3G and 2G networks.
However, the telecom operator has not revealed any details pertaining to the announcement which comes via company's official Twitter page. Thus there is no information about how the service provider is going to do it.
As Airtel uses TD-LTE to provide 4G services, consumers will need to have a smartphone with support for TD-LTE to use the service, which are not present in the Indian market as of now. Thus it is feasible to think that the company will probably ink an agreement with some smartphone vendor to provide such phones.
Reportedly, Airtel has been testing 4G LTE smartphones from Samsung, ZTE and other Indian smartphone vendors such as Micromax on its 4G LTE network.
