This is the MCQs in Wireless WANs: Cellular Telephone and Satellite Networks from book the Data Communications and Networking 4th Edition by Behrouz A. Forouzan. If you are looking for a reviewer in Electronics Systems and Technologies (Communications Engineering) this will definitely help you before taking the Board Exam.
The topic discussed the Cellular telephony which is designed to provide communications between two moving units, called mobile stations (MSs), or between one mobile unit and one stationary unit, often called a land unit.
