What a wireless network is made up of:-

Base stations, Access points, or Gateways

Wireless Network cards-Radios which send and receive signals from other radios or access points,

usually PCMCIA* cards which fit into Laptop expansion slots, or PCI Bus in

case

of Desktop computers. (There are other, simpler options using USB).

PDAs like PALM, and Pocket PC having a compact flash slot can also

connect.

* PCMCIA PersonalComputerMemory Card InternationalAssociation.

-The base station sends and receives radio signals to and from the Wi-Fi

radio in your laptop or PC, enabling you to share your Internet connection

with

other users on the network. Access points and gateways have a wide range

of

features and performance capabilities, but they all provide this basic

network

connection service.

Typical Community Wifi Constituents

High gain Parabolic grid antennas to beam the

signal to over30km from tower to tower..Typically 5.7-5.8 GHz, 2' Diameter Parabolic

Grid Antenna, 26 dBi gain, 6 degree beam

width, N-Female connector

Customer Premises equipment (CPE) to access

the signal from the towers..

Typically 23dBm Radio+15dBi Antenna = 38dBm

Sector antennas to beam the signal from the

towers to the community usersTypically 2.4-2.5 GHz, 90 degree sector antenna, 17dBi gain

Other components that need to be installed in order to

put the above systems together

THRIVE, Now a Wifi Campus

THRIVE has put Wifi to use within the campus using 802.11b wireless

technology.

The System consists of a NetGear Wireless Router mounted atop the

communication tower which beams a wifi signal accessible to anyone

using a wifi-enabled computer within the boundaries of the campus

without using any other amplifying antennae at about 300mts radius of

the tower.

THRIVE is in the process of setting up a campus monitoring and

surveillance system using wifi.

A visitor testing the wifi signal around

the THRIVE campus.

Capabilities and Uses

High data transmission rate and high reliability in all weather conditions,and an always available (95% Uptime) network makes wifi a robust solution

suitable for high bandwidth applications.

- Online video-conferencing with greater clarity

- Telephony, using VoIP

- Revenue-model for budding start-up ISPs

- Broadband in the true sense

- Easier reach into far-flung rural areas

- Ability to add more nodes as and when required

- Less maintenance overheads, especially in Ruralareas

where technical manpower is scarce

Successful Implementations of Wifi in India & AbroDigital Gangetic Plain Infothela

The researchers of Media Labs Asia based at IIT Kanpur have taken a technology designed

for indoor use as a replacement for wired local area networks and have stretched it to 75km

and beyond between Kanpur and Lucknow. They have made available a mobile koisk called

infothela whichis wifi-enabled and will provide a range of Govt. services from health to

education.

Bhutan - Internet Telephony using VoIP

A pilot project to use wireless and VoIP technologies to deliver communication services torural areas in Bhutan, a small Himalayan Kingdom, was completed with encouraging results.

Torornto Montreal Wifi Link along Rail LineTORONTO Canada's national passenger train service is offering wireless Internet access to

riders with their own Wi-Fi devices travelling between Toronto and Montreal

The Highest Wireless Network (WiFi - 802.11b) in theNortheast US

In the winter of 2003, a solar-powered Web camera was deployed in northern New Hampshire,

and in the process, the highest wireless network (WiFi - 802.11b) in the northeast United

States came into operation across 5 miles of backcountry.
