Efficient in Vast Areas

The use of MIMO 2T4R, against the normally used 2T2R, can get a coverage gain of above 4dB and reduce the number of base stations by over 45%. Beamforming 4T8R, against 4T4R, can get a coverage gain of above 2-3dB and reduce the number of base stations by above 30%. This helps the customer to heavily reduce the investment in equipment as well as operation and maintenance costs.

——Creating Quality Networks for WiMAX Ultra-Long-Distance Coverage

 

In today’s increasingly competitive world, an urgent issue faced by telecom operators is, for areas under ultra-long-distance coverage, how to use less equipment to achieve long distance or even ultra long distance coverage, and how to use less base stations, fewer investment and more flexible network construction and maintenance mode to meet the growing voice and data service needs of subscribers distributed in special areas and improve ARPU.

DifficultIies in WiMAX wide area networking

Ultra-long-distance coverage refers to the coverage of vast areas other than dense urban area, normal urban area, suburb and township, mainly including plain, mountainous area, desert, adjacent sea, lake, grassland and rural area. With economic and social development, these areas under ultra-long-distance coverage are generating growing needs for mobile communication, especially economically developed adjacent sea, lake and plain areas.

The communication in these areas features low subscriber density, small capacity and growing needs for data service, with a distance for coverage of dozens of kilometers, and radio signal propagation primarily of line-of-sight.

For wide area coverage in these areas, if normal macro cell or micro cell base stations are used, a large number of base stations are required to achieve satisfactory effects while the capacity is unlikely to be effectively used, remarkably increasing network construction and operation costs; and normal base stations have stringent requirement on site conditions, thus increasing operation cost and leading to the failure of many distant areas to meet site installation requirement.

Creating classic network for WiMAX ultra-long-distance coverage

With the deployment of WiMAX networkconstruction, the way to address these challenges and achievenetworkdeployment and operation in areasunder ultra-long-distance coverage with lowcost and high quality has become a big concern of operators.

If we can find a technical solution that remarkably improve base station coverage, and meet networkneeds for ultra-long-distance coveragewith the deployment of less base stations and less investment; if we can find a base station that is small with lowpower consumption, and flexibly mountable outdoors without being required to meet strict requirement for equipment roominstallation; if we cancarry out diversified services according to the characteristics of these ultra-long-distance coverage areas to rapidly improve ARPU; then all challenges will be readily solved and the classic network for ultra-long-distance coverage will be built.

As a leader in WiMAX industry, ZTE has been committed to such research and proposed an innovative solution for WiMAXultra-long-distance coverage.

Outstanding technology serving as safeguard

Ranging test algorithm  What is the most difficult to achieveultra-long-distance coverage in the WiMAXsystem is how to determine andcalibrate the distance between base station and terminal, and distinguish between all terminals within the covered cell. ZTE WiMAX proposed industrially leading Ranging test algorithm that overcomes ambiguous test phase upon excessively long distance between terminal and base station. Combined with highly sensitive receiver and flexible measurement and adjustment technology, it can properly meet ultra-long-distance coverage needs.

Multi-antennacoverage enhancement technology  ZTE WiMAXultra-long-distance coveragesolution uses MIMO, Beamforming, CDD and other industrially leading coverage enhancement technologies to effectively enhance single base station coverage by 20-40%. Currently in the industry, only ZTEcansupport4T8R Beamforming solution.

Array of high gain antenna ZTE WiMAXultra-long-distance coveragesolution uses a series of high gainantennae respectively on base station and terminal sides to further enhance coverage. High gain antenna is also used on the terminal (for example, panel antenna gain can reach over 12dBi), and by hanging outdoor terminal antenna higher,the signal transmission distance between base station and terminal is further increased, thus expanding coverage.

Flexible cost-effective networking solution serving as a foundation

Reducing cost of investment  ZTE WiMAXultra-long-distance coveragesolution, by using abovementioned technologies, greatly enhances single base station coverage. The use of MIMO 2T4R, agains the normally used 2T2R, can get a coverage gain of above 4dB and reduce the number of base stations by over 45%. Beamforming 4T8R, against 4T4R, can get a coverage gain of above 2-3dB and reduce the number of base stations by above 30%. This helps the customer to heavily reduce the investment in equipment as well as operation and maintenance costs.

Rapid and flexibleinstallation  The base station for ZTE WiMAXultra-long-distance coverage is small, with lowpower consumption, for outdoorapplication andfeaturing flexible installation,can help you to rapidly deploy the network, remarkably save space and reduce base stationinstallation and renting costs.

Green, energy saving and environmentally friendly  ZTE WiMAXultra-long-distance coveragesolution uses board design featuring improved power amplifier efficiency, high integrity and lowpower consumption, as well as RRU natural cooling, BBU intelligent temperature control technology, intelligent power saving algorithm and other methods. To address the difficulty in power supply in some ultra-long-distance coverage applications, remote power supply mode for base stationequipment can be provided. All these help the customer to reduce energy consumption in an all-round way and create a truly green, energy saving and environmentally friendly network.
