WiMAX supports ubiquitous broadband wireless access enabling real-time and multimedia applications. To bridge the digital divide, WiMAX networks are being deployed worldwide and the countries with no previous infrastructure are providing broadband access to users. Numerous statistical path loss (PL) models (e.g. Okumura- Hata, COST-231 Hata Model, ECC-33 Model) are available to predict the propagation loss, but are limited to the lower frequency bands (up to 2 GHz). Above 2GHz, propagation models require further validation and tuning through field measurements in different terrains and environments. The main objective of the work embodied in the present book is to provide design inputs for future WiMAX and advanced communication systems operating in the 2GHz band over India. An attempt has been made by the author to realize the objective by...
