No truck roll with indoor CPE businesses, and Users can be mobile Expectations for Mobile hotspots. Worldwide and retain Connection. WiMAX: High throughput (+1 standards. Cheap Expectations for new Mbps) while traveling at high devices available at releases to reach 1+ speeds retail. Future releases Mbps throughput will increase range and throughput Weakness 3G technology differs by Still in trial stages Limited range carrier/region – one High cost CPE Nomadic handset won’t generally Multiple Frequencies QoS still being worked work worldwide on for voice and video Uncertainty over how and who will deploy transmissions Source: In-Stat 7 8 WiMAX Suitability for Rural Areas Fixed WiMAX Technology Non-line-of-sight operation The last-mile broadband wireless could be achieved through the deployment of wireless LANs LAN traffic could be backhauled to the WiMAX network • Quick provisioning of high-speed connectivity to customers within the base station range. Support for voice and QoS and Wi-Fi / WiMAX together could • provide significant cost savings and • social benefits as multi-service application platforms for telecenters, government offices, schools and other organizations in rural areas 8 9 Typical Rural area connectivity using Wi-Fi / WiMAX Source: Regulatory Issues on WiMax Rajendra Singh Secretary, TRAI 9 10 Applications for rural customers E-governance Online bill payment Processing and submission of government documents Delivery of agriculture, healthcare and entertainment services In education, research and information sharing - e.g. university extension centers e-commerce activities including commodity price information, online trading and banking transactions Internet Kiosks Telecenters Post office kiosks Rural ATM’s Tele-medicine Tele-marketing Village enterprise development 10 11 WiMAX in India – Status C-DOT Alcatel Research Centre (CARC), a joint venture between C-DOT and Alcatel, has started lab trials for indigenously developed WiMAX technology. BSNL is setting up 10 WiMAX base stations (as part of a pilot project) at Bangalore, Chennai, Kolkata, Pune, Hyderabad, Ahmedabad, Hissar, Pinjore, Rohtak and Panipat. MTNL Plans WiMax Trials In Delhi And Mumbai Examples Teachers from Bishop Cotton School in Bangalore deliver live lectures (video conferencing) to high school students in Havara Giri School, Davangere (remote town in Karnataka) over the Internet using WiMAX/BWA (Broadband Wireless Access) for last mile connectivity. Citizen multiple video conferencing set-up wherein the deputy commissioner and officials at the taluk level interact with citizens at the telecentre in RG Halli and Navilehalli in Davangere district, all this being enabled through WiMAX (operating in 3.3-3.4 GHz frequency with 2 Mbps of broadband bandwidth available for video conferencing). 11 12 Way Forward Leading technology for providing high-speed wireless broadband connectivity for rural masses Challenges • Technology • Business / Operator • Logistic Key success factors • Low cost equipment • Good infrastructure facilities • Community specific content 12 Thank YOU!
