As an important player in the LTE market and a major contributor to the patent, Huawei believes that the industry has shown three major trends: TDD and FDD convergence will become the mainstream of the industry, LTE network construction will inevitably lead to multi-band, VoLTE is the key to LTE success.
TDD and FDD convergence will become mainstream
The convergence of TDD and FDD helps to improve the efficiency of use and user experience. The technology between the two is similar to 90%, and both have mature industry chains.
Consumers need faster access rates, a better user experience, and lower prices, without the technology behind them. But from the technology itself, operators must be able to provide the best service to users regardless of the spectrum in their hands, said Wang Tao, president of Huawei's wireless network business unit (BU).
Nearly 20 TDD/FDD converged networks have been put into commercial use around the world. It has been proved that by deploying the Huawei SingleRAN solution, the TDD/FDD converged network can reduce the investment by 21%.
LTE network construction to multi-band
LTE network construction is bound to multi-band, and all multi-frequency LTE networks can support carrier aggregation (CA) by 2016.
Olaf Swantee, chief technology officer of the UK EE, has said that EE has opened the world's fastest LTE-A network with a peak rate of 300Mbps; Joachim Horn, chief technology and information officer of Tele2, Sweden (Joachim Horn) believes that LTE-A will bring more experience to users. The challenge is how to find the right frequency band for aggregation; Alex Sinclair, Chief Technology Officer, Global System for Mobile Communications Systems (GSMA) It is pointed out that scattered spectrum resources require carrier aggregation to improve efficiency.
Wang Tao said that due to the characteristics of wireless technology, the current capacity and consumer demand still have a gap, the effective convergence of the spectrum to make the user experience better. Carrier aggregation is also a key feature of LTE-A, which will be supported in many markets and will have higher access rates.
VoLTE is the key to LTE success
Currently, LTE mobile phone users obtain voice services mainly by circuit domain fallback (CSFB) or OTT (VoIP). The former is a technology that allows LTE mobile phones to "fall back" to 2G/3G networks to complete circuit switched calls. VoLTE can achieve high-definition voice, which will drive users to accelerate the migration from 2G/3G to LTE.
Australia's Optus believes that the biggest advantage of VoLTE is high-definition voice quality and shorter call delay. VoLTE will be a weapon for operators to compete with OTT free voice. EE announced that it will achieve VoLTE voice coverage across the UK within three years.
In June 2013, China Mobile officially released the VoLTE white paper to the world during the Asia Mobile Communication Exhibition (MAE) to announce its LTE voice strategy and roadmap to the industry. This is also considered by the industry as an important measure for China Mobile to promote its LTE commercial strategy. . On July 26, it completed the VoLTE eSRVCC (enhanced Single Radio Voice Call ConTInuity) voice switching test in the world's first TD-LTE network environment with Huawei.
LTE test that can't stop at all: global electronic measurement technology and market leader - Keysight (formerly Agilent Electronic Measurement Division) UXM new product experience will be kicked off in the near future, welcome everyone in the industry to participate, your arrival It will be the greatest honor of KEYSIGHT!
