Abstract
The fundamentals required for steady growth of broadband wireless remain constant. According to the Ericsson’s official predictions, the global market of broadband connectivity will be around 320 million users by the end of this decade. The issues related with increased Deployment of WiMAX gives rise to issues related to QoS and Scalability. A unique methodology has been adopted to maximize the number of users per sector for multi-traffic users which include both Residential class as well as the Business class. The approach makes use of the Useful Bandwidth Estimations and implements an algorithm to provide a solution to QoS byrestricting the number of users according to Bandwidth allocated in both Uplink and Downlink directions. A modernize methodology to compute the system’s actual throughput and a traffic model for diverse application users are proposed with a step by step depiction to derive an algorithm to determine the maximum number of subscribers that each specific Mobile WiMAX sector may support. The results are shown using Matlab which intakes various system parameters along with Service class parameters and show the results in terms of the maximum number of users supported along with UL and DL bandwidth demanded and capacity available. The presented methodology would help those operators that plan to implement a wide coverage network in a city. Using the presented methodology, service providers will be in a position to estimate the exact number of base stations and hence the network investment and profitability.
