What is WiMax

• Stands for World Interoperability for Microwave
  Access
• A broadband wireless technology engineered to
  deliver the latest type of ubiquitous fixed and
  mobile services such as VoIP, Information
  Technology and Video at very low cost.
• Can cover a large geographical area, up to 50 km
  and to deliver significant bandwidth to end-users
  up to 72 Mbps

3
Why WiMax?

• Compared with other wired solution such as ADSL,
  or any other wireless or satellite system, WiMAX
  based access networks will enable operators and
  service providers to cost-effectively reach
  millions.
• Even truer for rural areas for which the
  cost/profitability and the demand factors are
  essential. This obviously includes
• adequate coverage
• Reliability
• performances (throughput)

WiMax-Easy to Install

• The ease to install
• one of the key issues to lower deployment costs
  in rural areas.
• In rural areas, the long distances from the core
  network access point and the scattered location
  of villages, farms makes any deployment very
  costly.
• The lack of main infrastructure (electricity,
  roads.), and environmental condition
  (temperature, humidity.) adds on the difficulty.
• WiMax provides NLOS/LOS coverage advantage

5
Wimax-The wide Coverage

• Important than the range limitation
• The capability to reach any potential user within
  the base station covering area
• Has been optimized to provide excellent
  Non-Line-Of-Site (NLOS) coverage (up to 15 Km
  around the base station) and long range
  transmission up to 50Km in LOS conditions.

6
Suitability for rural areas

• 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

Applications in rural areas

• 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 ATMs
• Tele-medicine
• Tele-marketing
• Village enterprise development

Status in India

• C-DOT Alcatel Research Centre (CARC), a joint
  venture between C-DOT and Alcatel, has started
  lab trials for indigenously developed
  WiMAXtechnology.
• BSNL is setting up 10 WiMAX base stations (as
  part of a pilot project) at Bangalore, Chennai,
  Kolkata, Pune, Hyderabad, Ahmedabad, Hissar,
  Pinjore, Rohtakand Panipat.
• MTNL Plans WiMax trials In Delhi And Mumbai

10
Current usage

• Teachers from Bishop Cotton School in Bangalore
  deliver live lectures (video conferencing) to
  high school students in HavaraGiri 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 taluka level interact with citizens at the
  telecentre in RG Halliand 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).
