The WiMax Evolution – Features, Architecture, Applications and Comparative analysis

Abstract

WiMax (Worldwide Interoperability for Microwave Access) is a remote broadband innovation, which bolsters point to multi-point (PMP) broadband remote access.. Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards including Wimax. OFDM technique has increased the speed as it carries multiple carriers, each carrying more than one data bits based on modulation techniques (QPSK, 16QAM). The IEEE remote standard has a scope of up to 30 miles, and can convey broadband at around 75 megabits for each second. This is hypothetically, 20 times speedier than an economically accessible remote broadband. This augmentation accommodates non-observable pathway access in low recurrence groups like 2 - 11 GHz. These groups are once in a while unlicensed. This additionally helps the greatest separation from 31 to 50 miles and backings PMP (point to multipoint) and work advances.
