Title: FIXED WIMAX CAPACITY AND LINK BUDGET CALCULATIONS
Author: Mohammed, Musab
Abstract: WiMAX stand for Worldwide Interoperability for Microwave Access, which is a telecommunication technology that provides wireless data in a variety of ways, from point-to-point links to full mobile cellular type access. It is based on the IEEE 802.16 standard, which enables the delivery of last wireless broadband access as an alternative to cable and DSL. The objective of this project is to better understand WiMAX system capacity and link budget calculations. System capacity refers to the number of connections that the wireless channel can support without unduly degrading the data services carried on the channel. In this project we will confine the capacity discussion to the OFDM physical layer in order to avoid a lengthy discussion of the additional complications that mobility introduces; including handover and dynamic cell occupancy. Determining the system capacity is very important because it is often prohibitively expensive to later overlay additional wireless capacity into the same coverage area, and without a firm understanding of the system capacity an operator has no way of estimating the recovery time for the up-front costs of deploying the access network, so understanding the system capacity is therefore key to deploying a commercially successful access network. Link budget planning is an essential part of the network planning process for both indoor and outdoor applications. A link budget helps to give dimension to the required coverage, capacity, and quality of service requirement in the network.
