Shah Alam and Kazi Tanvir Ahmmed Department of Applied Physics, Electronics and Communication Engineering, University of Chittagong, Chittagong-4331, Bangladesh E-mail: shah.alam@cu.ac.bd, tanvir@cu.ac.bd Abstract Fixed WiMAX is being deployed worldwide, and the networks are increasing in size. Measurements have been performed, but the amount of measurements are few and do therefore not demonstrate performance in a real life deployment. We have performed analyses of the physical performance in a fixed WiMAX deployment. The analysis presented in this paper focus on received signal strength and signals to noise ratio. Keywords: Fixed WiMAX, Physical Analysis, RSSI, SNR, NMS. Introduction Broadband wireless is a technology that promises high-speed (minimally, several hundred kilo bits per second) data transmissions occurring within an infrastructure of more or less fixed points, including both stationary subscriber terminals and service provider base stations, which themselves constitute the hubs of the network [1]. Worldwide Interoperability for Microwave Access (WiMAX) is a broadband wireless access system which offers high throughput, great coverage, flexible Quality of Service (QoS) support and extensive security. WiMAX is certified by the WiMAX forum [2], which is a certification mark based on the IEEE 802.16 standard [3, 4] that pass conformity and interoperability tests. Two major way of accessibility is offered by WiMAX standard namely Fixed WiMAX (802.16d) and Mobile WiMAX (802.16e). Fixed WiMAX delivers point to multipoint broadband wireless access to our homes and offices. WiMAX forum promises to offer high data rate over large areas to a large number of users where broadband is unavailable [5].The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL".
