With the rapid development of wireless access technology, the quantity of wireless sites of operators and enterprises increased fast. Compared to large footprint, high rental, high energy consumption of indoor site, outdoor site will become the mainstream for new sites. As the complexity of outdoor environment and numerous sites, high integration, high environment adaptability, high efficiency will be the evolution trend, even one cabinet or one pole will be a site. For evolution from single telecommunication power to site power, equipment housing ability and corresponding protection, heat dissipation, management functions need to be considered in site power.

Along the telecommunication network evolution from GMS, UMTS to LTE, mobile broadband network develops rapidly and multi-frequency multi-mode site brings a challenge to the power supply, for power supply should solves the expansion problems of cooling, capacity and power backup which accompanying the evolution. Quoted from statistical data, in all network accidents, 50% interruptions are caused by power supply, so choosing high available site power, will effectively improve the reliability of communication network.

Based on deep understanding of communication network, Huawei site power matching the design of the main equipments, these solutions are widely used in various wireless scenarios, such as outdoor macro site, outdoor DBS and outdoor macro + DBS site, and suitable for high temperature and cold & harsh environment, supporting network evolution and saving energy & footprint, passed the thermal simulation & design and the comprehensive test of electromagnetic interference, could effectively protect the reliable operation of main equipments, and have unified OSS with them.

Huawei could provide a full series of high efficient site power solutions; outdoor series power supply includes steel cabinet and aluminum cabinet to adapt different environments, and has the integrated, split product type to meet customer requirements of environment friendly. Rectifier module efficiency is higher than 96%, and the energy loss of power supply could reduce more than 60%; direct ventilation, heat exchange, TEC, AC air conditioner, DC air conditioner, and etc., various cooling type could adapt different environments and different loads. The cooling power consumption could realize more than 40% through precise cabin cooling. Huawei outdoor site power solutions could help customer to achieve in the energy-saving emission reduction strategy when comprehensive support client wireless business deployment.

TP48200A and TP48400A are the classic outdoor power products of Huawei, the main product features:

• TP48200A steel cabinet: 200A output capacity, large user space, small volume, flexible installation;
• TP48200A aluminum cabinet: anti-corrosion rust proof, adapt to harsh environment;
• TP48400A aluminum cabinet: large system capacity, support 5F3M, support network evolution in the next 5~10 years.

Huawei outdoor power system can realize centralized network management with zero cost in huawei through Huawei BTS, obtain the same reliability as the main equipment network, and have solved the common problems within industry about low reliability and huge maintenance cost of power system monitoring system. Huawei unified network management system can facilitate the management of power supply, environment and cooling, to help customers achieve site unattended and energy efficiency management.

Huawei outdoor power products have been widely used in the famous enterprises worldwide; and have help customer to fast deploy site, and solved the difficulties of hard site acquisition, slow deployment and high rental, and got effective result of reliable operation & energy-saving emission reduction.
