Wireless Communications Systems Design

11 Radio Planning

In Part III, we take a look at a big picture of wireless communication systems and use a top down approach. Many different interests are entangled in the wireless communications system design. The designed wireless communication system should satisfy various interested parties such as vendors, mobile operators, regulators, and mobile users. An officer of a regulatory agency takes a look at the wireless communication system in terms of an efficient spectrum usage and violation of the regulation for specific frequency bands. A mobile operator is interested in business opportunities, service quality, and the cost of the infrastructure. A mobile phone vendor or a network equipment vendor looks into the cost effective design of the wireless communication system. An end user is interested in good service quality and stylish mobile phones. For example, the designed wireless communication system copes with many channel impairments. The transmit power should be enough to cover users located in a cell edge. The battery life of a mobile phone should be long enough. It should support enough data rates at any place. The packet loss rate should be acceptable at any place. An end user is interested in whether or not it can use a network with enough data rates and seamless connection. Thus, we should consider all conditions and satisfy their requirements. In order to build wireless communication systems, we consider many system requirements such as spectrum, system ...
