Shanghai Unicom will invest CNY 1.07 billion in 4G this year

Updated:2015/10/22 09:39

China Unicom Shanghai branch (hereinafter referred as Shanghai Unicom) will invest CNY 1.07 billion in 4G LTE network this year, and its 4G sites will reach more than 9500 by the end of 2015.In order to provide better user experience, Shanghai Unicom will pre-commercialize VoLTE before the end of the year and deploy Carrier Aggregation (CA ) in some areas to realize the speed of 300 Mbps.

Li Zhimin of the Ministry of Planning and Construction of Shanghai Unicom noted that Shanghai Unicom’s subsequent evolution of LTE network will focus on the coverage, VoLTE function and 4.5G deployment.

According to the statistics announced on the eve of “17 May”, the World Telecommunications Day, Shanghai Unicom has deployed 6500 4G sites and realized 97.7% population coverage with the peak rate reaching 150 Mbps. And the third party comparison test of an authority shows that the indicators of the coverage, voice quality, data rate and other aspects of 3,000 key areas in the whole city is ahead overall. On this basis Shanghai Unicom will largely keep increasing the investment construction intensity of 4G network infrastructure and keep improving the network coverage. Shanghai Unicom will deploy more than 9500 4G sites by the end of the year.

4G subscribers of China Unicom obtain the voice service mainly by CSFB, namely making the voice falling back to 3G network. Shanghai Unicom is constructing VoLTE functions rapidly to make the subscribers perceive faster and smoother mobile networks and to realize the voice business experience of no calling delay£¨below 3 seconds£©, HD sound quality(2 times the voice quality) and HD video (10 times the resolutions).

Meanwhile,Shanghai Unicom has boldly adopted creative means of cloudization in VoLTE deployment and has first started the pilot VoLTE network construction based on NFV in China, which is a major step of future network architecture.

Shanghai Unicom always spares no effort to promote the network “one step ahead”. After first realizing the peak rate of 42 Mbps with DC-HSPA+ in 2012 and 150 Mbps with FDD-LTE in 2014, Shanghai Unicom puts emphasis on LTE CA pilot and commercial trial in hot business districts with the peak rate reaching 300 Mbps this year. The 4G+ CA deployment areas are dominated by the areas inside the Inner Ring, expanding to Hongqiao Transportation Hub, Pudong Airport, the subway lines, the university areas and other scenes. As the iconic 4G subsequent evolution technology, CA solves the spectrum fragmentation problem and lifts the network speed multiply by aggregating several continuous or discontinuous LTE carriers to transmit data.

In addition, Shanghai Unicom launches LTE-M service to develop the applications of IoT. Li Zhimin said that the special functions based on the IoT are a feature of China Unicom, and Shanghai Unicom has certain expertise and accumulated experience in the area, such as its cooperation with BMW and intellectual meter reading. And the advantages of LTE-M service lie in the plug and play device deployment£¬lowering the device cost through mass production, supporting in-depth coverage aiming to realize being online anytime and anywhere and high spectral efficiency facing to the future evolution.

On the eve of Mobile World Congress Shanghai 2015, Shanghai Unicom has deployed the first sample point of 4.5G cellular IoT network technology and has piloted the intelligent parking service in Shanghai, which will be applied widely afterwards in Disneyland Shanghai and other areas.
