Huawei demonstrates doubling of data rates in LTE-Advanced trial

Huawei announced this week (26 September 2012) it has successfully conducted the world’s first LTE-Advanced (LTE-A) uplink coordinated multi-point (CoMP) trial on several commercial LTE networks in Europe and Asia.

The LTE uplink CoMP field trial was designed to demonstrate the capability of Huawei’s No-Edge Network concept in enabling the best mobile broadband experience in terms of achievable download speeds. The results showed that uplink CoMP can effectively double data rates at cell edges for a single user, improving network performance in terms of coverage, spectrum efficiency and throughput.

At the 2012 Mobile World Congress, Huawei held demonstrations for the world’s first LTE-A inter-band carrier aggregation (CA) and heterogeneous networks (HetNet). Huawei’s strategy for LTE and LTE-A is focused on the development of efficient, sustainable and profitable mobile broadband networks that bring people an improved service experience.

‘This is a key milestone for the LTE industry,’ said Ying Weimin, Huawei President for GSM/UMTS/LTE Networks. ‘Our No-Edge Network concept utilizes various LTE, LTE-A and innovative future-oriented technologies to realize ultra-broadband, zero-waiting and ubiquitous connectivity. This results in an enhanced experience and brings users the benefits of speed, quality and simplicity.’ 

LTE Advanced is an evolution of the current LTE standard and is designed to be compatible with it and use the same frequency bands. LTE-A will bring a number of benefits some of which are available now, while others are still being worked on.

One key benefit is that mobile operators will be able to take advantage of advanced topology networks, where they can optimise ‘heterogeneous’ networks, which are made up of a mix of macrocells and a range of small cells with low power nodes. This will provide a better customer experience as the low power nodes (piccocells, femtocells) are sited closer to end user. 

It will also improve the capacity and coverage of the mobile phone network. LTE-A introduces carrier aggregation technology, which will support very high data rate transmissions over wide frequency bandwidths up to 100MHz.
