­UAE based mobile network, du has announced the successful testing of two regional firsts on its LTE based 4G network.

The company tested Circuit Switched Fallback, which provides a mechanism to hand over voice calls to du's 3G network. This enables customers to run data connections over LTE, while also being able to receive and place voice calls a 3G network without interrupting their mobile broadband connection. du's existing 3G network has been already upgraded to support high definition (HD) voice, which will further enrich the quality of voice calls.

The company also tested 4x4 MIMO: Using this technology, du has successfully tested and achieved mobile broadband speeds of 300 Mbps on its 4G LTE network.

Hatem Bamatraf, Executive Vice President, Network Development and Operations, du commented that "While there are currently no handsets that support mobile broadband speeds of 300Mbps, we will introduce two new features soon to our 4G LTE customers, to greatly improve their experience."

The company also tested Connected Mode Discontinuous Reception (C-DRX): A feature that can potentially result in battery life savings for 4G LTE smartphones. It does so by intelligently controlling the amount of time spent by the smartphone to communicate with the network - thus resulting in power savings.
