IMPROVING/INCREASING COVERAGE AND CAPACITY IN CELLULAR SYSTEM (AN INTRODUCTION) Prepared by MUHAMMAD ARIF 2010-TE-010 TE7C Wireless & Mobile Communication (TE-432) Department of Telecommunication Engineering Sir Syed University of Engineering & Technology, Karachi.

Need of Improving/Increasing Coverage and Capacity of Cellular System  When cellular service providers build their networks, their networks are designed to provide coverage to the area of desire with the expectation of possible increase in population (number of users) in the near future.  As the demand for wireless service increases, the number of channels assigned to a cell eventually becomes insufficient to support the required number of users. Wireless & Mobile Communication (TE-432) Department of Telecommunication Engineering Sir Syed University of Engineering & Technology, Karachi.

75% Need of Improving/Increasing Coverage and Capacity of Cellular System Wireless & Mobile Communication (TE-432) Department of Telecommunication Engineering Sir Syed University of Engineering & Technology, Karachi.  Unavailability of the channels means that the call blocking probability has increased and this is not desired in the system.  At this point, cellular design techniques are needed to provide more channels per unit coverage area.

Techniques of Improving/Increasing Coverage and Capacity of Cellular System Wireless & Mobile Communication (TE-432) Department of Telecommunication Engineering Sir Syed University of Engineering & Technology, Karachi.  There are several techniques to expand an already existing network or to add more capacity to a network being built.  Techniques such as cell splitting cell sectoring are used mainly in practice to expand the capacity of cellular systems.
