Unveils new offerings in LTE, traffic admin; completes MS Lync IOT

Huawei gears up for new network era
Huawei unveiled a range of new offerings for next-gen networking and communications.

China-based Huawei today announced a range of new products and project closures, from time-delay duplex LTE technologies to unified communications and traffic bandwidth optimisation.

The company recently showcased its enhanced-performance solutions for LTE TDD. These solutions include Adaptive Beamforming, Adaptive Inter Cell Interference Cancellation (aICIC) and Coordinated Multiple Points (CoMP) technologies, which improve LTE TDD edge user-download speeds by 30% and upload speeds by 10%.

It is predicted that there will be more than 50,000 LTE TDD sites globally by the end of 2012, and that there will be 10 times as many sites in 2014. As LTE TDD continues to rapidly develop worldwide, Huawei argues that "improving end user experience and controlling operation costs will become critical challenges for operators to face".

Aside from TDD's advantage of asymmetrical download and upload speeds for higher speeds, Huawei's CoMP solution is designed to improve cell edge upload speeds by 10% while aICIC is built to assures the best interference control at the cell edges and Adaptive Beamforming dynamically matches the best multi-antenna mode according to user signal strength. aICIC and Adaptive Beamforming respectively improve connectivity for users at cell edges by 30% and 20%.

Huawei also revealed uTraffic, a network traffic analysis system. Based on Huawei's own performance management platform, uTraffic enables carriers to analyse network traffic and flow, in order to monitor the quality of network "pipes".

Due to the emergence of new services such as mobile Internet, high-definition video, online gaming, and cloud applications, data traffic is growing drastically and bandwidth needs are continually expanding. For many carriers, revenue is not increasing with the growth in traffic, with network "pipes" now overloaded. The ability to proactively monitor and optimise network traffic is the biggest challenge carriers face in terms of network operations and maintenance.

Lu Hongju, president of Huawei's Fixed Network OSS & Service Product Line, said: "Mobile broadband has evolved from the global system for mobile communications to long-term evolution. Fixed broadband has evolved from traditional voice and Internet applications to high-definition video and cloud applications. Network traffic will increase tenfold and more in the next three years. Carriers are faced with rapid network traffic growth, dynamic traffic changes, and traffic flow uncertainties. Visualising and optimising network traffic and flow, enhancing the transmission efficiency of network ‘pipes', and improving service quality and experience are key issues that carriers need to solve immediately."

The uTraffic system was designed to address these issues, Huawei said. It can display overlapping physical topologies, geographic information system (GIS) mapping, network traffic, and also locate traffic congestion points. By analysing traffic, uTraffic can predict traffic and broadband utilisation rates for the next one to three months, in addition to forecasting where the bottleneck in the "pipe" is likely to occur, Huawei claims. UTraffic is also designed to support network expansion, using embedded probe technology to monitor traffic and "pipe" quality to an accuracy of 10-6, the highest in the industry, according to Huawei.

The China-based company also announced the completion of an Interoperability Test (IOT) between Huawei's IP private branch exchange (PBX) and Microsoft Lync.

Both companies indicated their intention to strengthen cooperation in Unified Communications (UC), Contact Center (CC), TelePresence (TP) and Video Conference (VC), as well as showcase joint solutions at the Microsoft Technology Center (MTC).

During the IOT, the Huawei eSpace U1930 gateway was used as the IP-PBX to connect with Microsoft Lync Server 2010. According to Huawei, the IOT "confirms that this device delivers a wider range of UC services to users, facilitates the access of Lync to the public switched telephone network (PSTN), and is compatible with the existing telephone system, thereby reducing the need for additional investment by customers". In addition, enterprise users can also use Huawei's IP-PBX to join Lync conferences.

Yi Zhiquan, general manager of Huawei's UC Products, said: "The successful interconnection between Huawei's IP-PBX and Microsoft Lync showcases the excellent features of Huawei's UC products on convergence and openness, and further enhances the joint competitiveness of Huawei and Lync. Such interoperability applications will enrich the service offerings for UC customers and deliver better service experience to customers."
