1.2 BROADBAND DEVELOPMENTS
As large portion of the global communications infrastructure is represented by wireless technology, it is vital to understand overall broadband trends and the role between wireless and wire line communication technologies. Several times both wire line and wireless technologies competed with each other, but generally, they are complementary to each other. For the most part, core infrastructure and backhaul transport for wireless networks are based on wire line technologies, whether copper wire or optical fiber.
1.2.1 Bandwidth Management
Operators are both considering and implementing several techniques for managing bandwidth which are as follows
(a) More Spectrum: Spectrum correlates directly to capacity, and …show more content…
The immense world -wide success of mobile wireless communication and now with the growing urge of mobile data conclusively demonstrates the need for mobile-oriented communications. Mobile broadband communication combines high-speed data rate services with mobility management entity. In comparison of wireless technology, wireline technology has comparatively increased capacity and delivers throughput at faster rates. Table 1.3 summarizes the strengths and weaknesses of wireless versus wireline broadband approaches.
1.2.3 Energy saving strategies for wireless networks
With the introduction of smart-phones, demands for data rates are increasing day after day. This will cause the deployment of more number of base stations and as base station is the main source of energy consumption so reducing base station energy consumption is necessary. There are several strategies to reduce energy consumption of base station as described by Steve N. Roy et.al (2008) [5] which are as follows
(a) Remote radio units: This strategy basically consists of moving radio equipments like RF converters and power amplifiers from the base of the station to the top of the tower close to the antenna and connecting them via fiber …show more content…
The energy consumption will be reduced due to higher set point which means that the unit will be turned on less frequently and also it will run more efficiently due to the higher temperature delta at the air exchange.
(e) DC power system ECO mode: This strategy of radio ECO mode is used to further reduce the load during low traffic periods especially during night time. In this an advanced system controller scheme is used which can ensure that rectifiers will operate at their high peak efficiency independent of varying conditions. Thus, the optimized use of rectifiers can increase the system efficiency up to 90%.
(f) Higher efficiency rectifiers: This strategy basically consists of using highly efficient rectifiers. With the aid of this method, DC system efficiency can reach to 94%. Table 1.4 summarizes the network energy saving strategies with their savings in
