Wireless communications is the fastest growing segment of the communications
industry. Cellular systems have experienced exponential growth over the last decade. In addition, wireless local area networks currently supplement or replace wired networks in
many homes, businesses, and campuses. Many new applications, including wireless sensor networks, automated
highways and factories, smart homes and appliances, and remote telemedicine, are emerging from research ideas to
concrete systems.
Future communication technology utilizes millimeter waves for high-speed internet, radar, and wireless systems, evolving from Marconi's Frequency Selective Surface invention in 1919, impacting various fields like radio astronomy and remote sensing.
