Wireless Networks and Internet in the Himalayas
  • In 1997, Himanchal Higher Secondary School in the
    remote Myagdi received four used computers as
    presents from the students of a school in
    Australia 
  • Two 386 PCs, one 486 PC, and one laptop (486 PC)
  • Mahabir Pun, one of the teachers had the vision
    of trying to connect to the Internet
  • Some people mentioned Wi-Fi 802.11b Technology
  • That is how it all started.

  • Major hurdle was connecting to the Internet, only
    available in Pokhara, a city aprrox. 50 Km away.
  • A big mountain was in the way.
  • Only solution was to place a repeater in the
    mountain
  • RELAY TREE ?

  • Present Status

9
Wireless Networks and Internet in the Himalayas
  • Currently 5 Villages are connected to the
    wireless network
  • All villages are using email and Internet
    services
  • This is vital infrastructure in a place where
    there are no means of transportation and
    communication except walking
  • Villagers who cannot type also use NetMeeting to
    communicate with family in other villages
  • Yak farmers who travel to remote areas and are
    out of home for long time are able to communicate
    with family

14
Wireless Networks and Internet in the Himalayas
  • Good News for the Future!!!
  • Received 20,000 Grant from the World Bank
    through Competition
  • This means the network can now be expanded to 14
    villages and 3 districts

  • What new services will we have?
  • E-HealthDoctors in the city can contact patients
    in villages
  • E-CommerceProducts from one village can be sold
    in other villages. Hopefully local handicrafts
    can be sold internationally.
  • Tele-teachingVillage schools lack teachers.
    Teachers in one school can teach students in
    other schools using video conferencing.

  • What else can be done?
  • Implement Ipv6 for multicasting of Tele-teaching
    services?
  • That would be great!

20
Wireless Networks and Internet in the Himalayas
  • Unique Properties of this Network
  • WiFi 802.11b technology originally designed to be
    used inside buildings and rooms is being used
    over very long distances to connect remote
    villages in the mountains
  • Highly beneficial to Nepal
  • Wireless Communication best-suited for Nepals
    mountainous terrain
  • Can be replicated at low cost all throughout Nepal

21
Wireless Networks and Internet in the Himalayas
  • Issue of sustainability
  • The recurring cost is that of Internet
    Connection, which needs to be paid monthly
  • This can be obtained by opening Cyber Cafés in 3
    tourist villages in the famed Annapurna Trekking
    Circuit
