Huawei Interpret Three Major 4G Trends: VoLTE is The Key To The Success of LTE

Global mobile Suppliers Association (GSA) has recently confirmed that, 251 LTE networks are now commercially available in 93 countries and regions. Following China Mobile TD-LTE commercial start, China has become the latest in the market.

As occupy an important position in the LTE market players and major contributor to the patent, Huawei believes that the development of the industry presents three major trends: TDD and FDD integration will become the mainstream industry, LTE network construction will inevitably move toward multi-band, VoLTE LTE is the key to success.

Fusion TDD and FDD help to improve the efficiency and user experience, technology between the two has 90% similarity, but also have a mature industry chain, TDD/FDD multimode terminal in the third quarter of 2013 will achieve 25% growth.

“Consumers demand access speed that faster, better user experience and lower prices, not matter the technology behind them. But from the technology itself, regardless of the hands of the operators need to have any spectrum which can provide the best service to users,” said Huawei Wireless Network Business Unit (BU) president Wang Tao.

Currently there are 13 global TDD/FDD converged networks put into commercial. Proven by practice, through the deployment of Huawei’s SingleRAN solution, TDD/FDD converged network can reduce 21% of input.

Toward multi-band LTE network construction

LTE network construction will inevitably move toward multi-band and multi-frequency. By 2016, all LTE networks are able to support Carrier Aggregation (CA).

British EE CTO, Olaf Swantee stated that EE has opened the world’s fastest LTE-A networks, the peak rate of up to 300Mbps.

Sweden Tele2 Chief Technology and Information Officer, Joachim Horn believe LTE-A will bring more experience for the user, the challenge is how to find the right band polymerization.

Global mobile communication systems Association (GSMA) CTO, Alex Sinclair pointed out that the scattered spectrum resources needed to improve the efficiency of carrier aggregation.

Wang Tao said that due to the characteristics of wireless technology, current capacity and consumer demand are still gaps, the spectrum of effective convergence makes the user experience better. Carrier aggregation is also a key feature of LTE-A, and in 2014 will support the technology in many markets, the access rate will be higher.

Huawei can provide end-to-carrier aggregation solutions, announced third quarter 2013 commercial carrier aggregation chips.

LTE VoLTE is the key to success

Currently, LTE mobile phone users access to voice services primarily to the circuit domain down (CSFB) or OTT (VoIP) implementation, the former is a technology that allows LTE phone “down” to the 2G/3G network to complete the technical circuit switched call. The VoLTE can achieve high-definition voice, will drive users to accelerate the migration from 2G/3G to LTE.

Australia’s Optus believes that the biggest advantage is that VoLTE HD voice call quality and shorter latency, VoLTE will be the operators and OTT free speech competitive weapon. EE announced that it will achieve VoLTE voice within the UK-wide coverage within three years.

In June this year China Mobile officially released a white paper for the global during the exhibition Mobile Asia Exhibition (MAE) VoLTE, to declare its LTE voice industry strategy and roadmap, which is also the industry that is China Mobile LTE commercial strategy to promote the important initiative. July 26, which together with Huawei to finished first global TD-LTE network environment VoLTE eSRVCC (enhanced Single Radio Voice Call Continuity) voice switching tests.

Huawei is expected to accelerate commercial VoLTE in 2014.
