WiMAX is an effective metropolitan area broadband access technology, supplying wireless coverage over an area of several kilometers with high data rates. WiMAX technology has introduced WiMAX broadband to provide an alternative to the high cost of broadband connection through cable or DSL. In this paper, simulative investigations have been done for the WiMAX network using different path loss models. Investigations have been done in terms of performance metrics such as path loss, throughput and delay. Considering VoIP as major application, extensive results of different path loss models have been indicated which will help the network engineers in planning and design.
