  1. Evolutionof Wireless Data Communication

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

  3. Broad band local Area and ad-hocnetworks Wireless LAN • Wi-Fi - IEEE 802.11 based networks • Wireless ATM • HIPERLAN-ETSI based network Wireless PAN • Bluetooth- IEEE 802.15 • HIPERPAN- ETSI based

  4. Evolution of mobile networks Generation of Wireless networks 1st generation - analog system eg: AMPS, TACS. 2nd Generation - digital system eg: GSM, IS-95, IS-136. 2.5 Generation/Evolved 2nd Generation 3rd generation 3.5 generation/Evolved 3rd Generation 4th generation ?

  5. Evolution of Mobile data networks 2G 2.5G 3G 3.5G 4G HSDPA GSM GPRS EDGE UMTS IS 95 CDMA 20001X CDMA 2000 EV DO CDMA 2000 EVDV

  6. GPRS/EDGE BSC & PCU SGSN FE FE GGSN E1 BTS Mobile/PDA FE GPRS modem ISP & Internet

  7. CDMA2000 1X/EVDO PDSN BSC & PCF FE E1 BTS FE P-card USB modem Ethermax router ISP & Internet FE

  8. New Markets & Networks Evolved between Broad band local & ad-hoc and wide area mobile market • WiMAX-IEEE 802.16 based • HIPERMAN- ETSI based • WiBro – South Korean initiative, could be considered as part of IEEE 802.16e • Mo-Fi - IEEE 802.20 based still not standardized • Wi-TV-IEEE 802.22 based still not standardized

  9. IP/MPLS Wi Max Base Station PE FE Subscriber Station
