Evolution of Wireless Data Communication

Market sectors in Wireless Applications Voice oriented market Data oriented market Evolved around wireless connections to PSTN Evolved around Internet and computer communication network infrastructure. a. Local Area market Low power, low mobility, high Qo. S. , etc Eg: cordless telephone, PCS, wireless PBX b. Wide area market High power, comprehensive coverage, low Qo. S Eg: cellular and mobile telephone a. Broad band local Area and ad-hoc market Eg. WLAN, WPAN b. Wide area mobile market Internet access to mobile users. Eg: GPRS, EDGE

Broad band local Area and ad-hoc networks Wireless LAN 1. Wi-Fi - IEEE 802. 11 based networks 2. Wireless ATM 3. HIPERLAN-ETSI based network Wireless PAN 1. Bluetooth- IEEE 802. 15 2. HIPERPAN- ETSI based

Evolution of mobile networks Generation of Wireless networks 1 st generation - analog system eg: AMPS, TACS. 2 nd Generation - digital system eg: GSM, IS-95, IS-136. 2. 5 Generation/Evolved 2 nd Generation 3 rd generation 3. 5 generation/Evolved 3 rd Generation 4 th generation ?
