WiFi Fundamentals

• Wi-Fi, or Wireless Fidelity, is freedom it
  allows a person to connect to the Internet from
  your couch at home, a bed in a hotel room or a
  conference room at work without wires.
• Wi-Fi is a wireless technology. Wi-Fi enabled
  computers send and receive data indoors and out
  anywhere within the range of a base station.
• Its just as fast as a cable modem connection.
• Allows you to access the Internet while on the
  move you can remain online while moving from
  one area to another, without a disconnection or
  loss in coverage.

HotSpots

• What is a HotSpot?
• A HotSpot is a geographic area that has a readily
  accessible wireless network.
• HotSpots are equipped with a Broadband Internet
  connection, and one or more Access Points that
  allow users to access the Internet wirelessly.
• HotSpots can be setup in any public location that
  can support an Internet connection. All the
  locations discussed previously are examples of
  HotSpots.

Typical Wi-Fi Users
Now that we know about WiFi, who are the likely
users of WiFi services?

• Frequent Travelers
• Businessmen and Corporate Managers
• Scientists Doctors
• Students and Academicians
• Administrators Technocrats who participate in
  Seminars Conferences
• Just about anybody with a laptop

7
What are the good places to install WiFi?

• Basically, any location which caters to
  business users, and where people with laptops are
  likely to make frequent visits is an ideal choice
  to install WiFi.

• Airports
• Hotels Resorts
• Restaurants
• Coffee Shops
• Bookstores
• Shopping Malls

• 2.MAC
• 3.USER NAME PASSWORD
• 4.CREDIT CARD
• 5.SMS (FOR EXISITING BSNL SUBSCRIBERS ONLY)
• 6.COMBINATIONS OF 1,2,3.

11
Components required for WiFi

• A PC, laptop or PDA, running Windows 98 or
  above.
• A wireless PCMCIA card, or a wireless adapter.
  Now a days all the latest LAPTOPS are coming with
  in built CENTRINO
• A Network Interface Card (optional) - Only if a
  LAN connection is required)
• An Access Point - essentially a compact radio
  transmitter with an antenna that connects to a
  wired connection, such as an Ethernet, DSL, or
  Cable Network.
• A valid internet connection.

12
Components required for a larger environment

• Multiple Access Points - To provide overlapping
  coverage throughout a site. Access points can be
  installed almost anywhere.
• Network switch - A device that joins multiple
  computers together. A set of Access Points can be
  connected to a single network switch.
• Wireless LAN bridge (optional) A wireless LAN
  workgroup bridge enables connection between two
  different hotspot networks.

13
Components required for a larger environment

• Authentication and Billing Server Enables
  control access to the Wi-Fi hotspot network by
  conducting authentication checks similar to
  credit card or member ID authentication. Also
  tracks wireless usage for billing purposes and
  provides payment transaction services.
• Wireless Access Gateway A device which connects
  wireless subscribers to the wired network. It
  employs one Ethernet port to interface with the
  router and one wireless subscriber port that
  supports IEEE 802.11b/g standard .

Role of Territorial Circles
1. Selection of Hot Spot sites. 2.
Liasioning work with the end customers. 3.
Finalisation of terms and conditions with the
site owner. 4. Backhaul (either through
fiber or ADSL or MLLN with FE input
etc..) and infrastructure support to
project circle for installation of the
equipment. 5. Allotment of space and power
supply for access points. 6.
Maintenance of equipment after taking over
from project. 7. Executing AMC with the
Vendor.
25
Role of Project Circles
1. The four Project Circles will be responsible
for coordinating the installation and
commissioning of WiFi eqpts, under their
