Nokia Siemens Networks (NSN) has become a member of the Global TD-LTE Initiative (GTI) Partner Forum.

The GTI is an industry body that advocates and promotes 4G mobile broadband using TD-LTE technology. The vendor has been an active participant of the forum since its inception.

NSN has seven commercial TD-LTE deals around the world, in Asia, Middle East, South America and Europe, most of which are already live, and is engaged in large-scale field trials with China Mobile and other operators.

The company offers a complete portfolio with network infrastructure, devices, applications and services for TD-LTE. NSN is actively engaged in multiple GTI technical taskforces that address various issues of TD-LTE commercialisation and deployment. This work includes network planning, voice solutions for TD-LTE handsets, co-existence of TDD and FDD, and multi-antenna solutions.
