Huawei has already successfully enabled this voice service evolution for PCCW Hong Kong.

Enhanced Spectrum Efficiency, Reduce OPEX

As the era of Big Data comes, the management of spectrum resources will be even more critical for operators and future network deployment schemes need to be equipped with muti-mode, muti-frequency band capabilities. Currently spectrum resources are still scarce, fragmented, and inefficient forcing operators to incur large cost to acquire additional spectrum resources.

Huawei has three major planning solutions (GSM LTE Refarming, TDD/FDD Coordination, and Small Cell Co-Carrier) for operators to enhance spectrum efficiency and save on operating expenses.

The GSM LTE Refarming solution is a cost effective way to improve spectrum efficiency while expanding network coverage. This refarming process can inadvertently result in the decline of the GSM network performance; Huawei can readily address this issue with three key technologies (dense frequency multiplexing, smooth migration of cell-level traffic, and non-standard bandwidth). These techniques have proven to significantly improve spectrum efficiencies up to 25%, with 24% bandwidth savings. During the subsequent LTE Refarming activities there was an improvement in the MR, which reduced the buffer zone site number by 25% eliminated interference with other channels and expands the LTE service area. Huawei is the current market leader in GSM LTE Refarming and has already provided services to operators including Hutchison Hong Kong, Optus Australia, Vodacom South Africa, and Maxis Malaysia.

The TDD/FDD frequency band has been widely introduced into the mobile communications networks, and while existing resources are now better utilized, fragmentation can occur between frequency bands deteriorating service quality. Huawei's LTE FDD/TDD hybrid networking planning and optimization process compensates for these spectrum fragments to enable the operator to realize seamless FDD/TDD coverage. This is accomplished through a switchover strategy between multiple frequency bands and modes with a dynamic distribution strategy. The first TDD/FDD coordinated commercial network, using this concept was introduced into the industry and was delivered to Aero2 Poland.

Huawei is an innovator of the Small Cell Co-Carrier design concept. This design can effectively expand the network capacity more than two times that of the current capacity with a uniquely embedded dynamic sensitivity algorithm and design plan. Huawei was the earliest vendor to deliver the industry's first coordinated multiple point (CoMP) to curb interference caused by Small Cell Co-Carrier networking.

Improved Network Performance with IBS

In many cases LTE access to high-speed data services are primarily indoors requiring particular attention to address in-building issues. In order to ensure seamless in-building LTE network rollout most operators are faced with the challenge to balance the need for increased network capacity with high performance capabilities with a fast deployment times all while reducing operating costs through use of existing 2G/3G systems.

Huawei's fully integrated LTE in-building solution (LTE IBS) is the best choice for operators to implement a customized evolution plan. This solution enables operators to capitalize on their existing investments based on the existing 2G/3G network resources and the future LTE development plan. LTE IBS provides precise indoor-outdoor coordinated planning with interactive simulation for an optimization services that can guarantee network performance improvement by balancing indoor-outdoor traffic distribution, improved resource utilization, and controlled LTE co-carrier interference.

To fully utilize existing systems to ensure the protection of existing equipment investments, Huawei integrated evaluation platform can thoroughly assess the operator's network from a multi-dimensional view which includes coverage, traffic, and performance. Based on the predicted ROI, Huawei can precisely customize optimization plans to cater to the various in-building deployment scenarios during network evolution. For highly complex scenarios that are difficult to reconstruct, Huawei's industry's first SingleMIMO solution helps operators achieve LTE MIMO and save reconstruction costs without changing existing feeders.

Network construction costs for historic landmarks, municipal buildings, airports, stadium and special event facilities are huge. Huawei's site co-building solution supports the sharing of existing frequency bands between multi-system, multi-vendor, and multi-operator by precisely adapting to the capacity of different systems through data carrier scheduling. The site co-building solution's module-based design which also enables flexible capacity expansion and a smooth evolution. In addition the entire network's administrative system can be streamlined to achieve visible indoor-outdoor coordinated management to greatly reduce the operations and maintenance (O&M) costs.

In accelerating LTE base commercial applications, Huawei's industry-leading technical solution has helped operators deploy more than 2,100 in-building LTE sites as of the third quarter of 2012. Huawei NIS solution provides a comprehensive range of customized E2E integrated delivery services to support the needs for global network rollouts and the operators' business development plans, This solution enables operators to flawlessly implement network expansion plans to shorten their time to market while maintaining a higher level of service quality reducing network construction costs and effectively protecting the operator's investment resulting in more profits for the operators.
