2007 witnessed the continuous growth of 3G networks. GSM networks still have much vitality in the next five years, and emerging technologies such as WiMAX and LTE have been highlighted in commercial application agendas. Rapid changes in mobile network modes and upgrades in technologies have raised a challenge to operators: How to seamlessly integrate various network modes and technologies?
The accelerated growth of mobile broadband video services - coupled with an ever greater user base and a higher average Minutes of Usage - is mounting increasing pressure on mobile operators in terms of network expansion and operation. To win out, mobile operators not only need to control the construction and operation costs in an end-to-end manner, but also need to take up the social responsibility of environmental protection, energy savings and emission reductions. Huawei has been focusing on the pressures and challenges faced by operators, and has predominated the four technical directions of "Green, Convergence, Evolution and Broadband."
Huawei has proposed its "Green Site" solution that integrates a range of innovative technologies to reduce the number of cabinets required by traditional BTSs from 10 to 1. Meanwhile, the BTS capacity is increased from 12 to 36/72 carriers, and the system power consumption is halved to 800W. Embodying a win-win situation, the solution delivers both environmental and economic benefits for operators.
The need for seamless integration of different network modes and technologies has inspired Huawei's fourth generation BTS platform. Breaking the system barrier, the integrated platform supports various network modes such as UMTS, CDMA, WCDMA and LTE. Software upgrades facilitate changes between different modes, and this greatly simplifies operators' cost structures in a way that protects long-term investment by ensuring smooth future evolution.
In terms of mobile broadband, Huawei has taken a leading step in IP transformation research and raised the IP BSS/RAN solution. This solution provides an end-to-end IP-based architecture, including kernels, interfaces, and service guarantee mechanisms, which enables operators to substantially reduce transmission cost, improve QoS, and expand bandwidth and throughput, thus allowing flexible mobile broadband service deployment and smooth service adaptation.
Now Huawei has become a key strategic partner for mobile operators worldwide. Successful cooperation with Vodafone Spain sparked Huawei's selection as the supplier for Vodafone's subsidiaries in Greece, Romania and Hungary. Telefonica/O2 deployed Huawei's dual-mode (2G/3G) BTSs to optimize its GSM networks in southern Germany, and was further awarded its HSPA+++++++++++++++++++++++++ contracts for Brazil, Mexico, Argentina and Chile. France Telecom selected Huawei to construct wireless networks for its operations in Belgium, Romania, Poland and the Greater Cairo region of Egypt's Mobinil. In Australia, Optus selected Huawei as its sole contractor for the world's largest UMTS 900 network. In India, Reliance partnered with Huawei in building its GSM network of 300 thousand carriers. In Chicago, Huawei successfully deployed America's first All-IP CDMA network.
The new wind vane for the global mobile market has come to fruition. Huawei and its innovative mobile solutions represented by the fourth generation BTS will help operators stride into the new mobile era.
