3. INTRODUCTION
There are basically three different options:
BROADBAND ACCESS
WIFI ACCESS
DIAL-UP ACCESS
The main problems with broadband access are
that it is pretty expensive & it doesn’t reach all
areas.
The main problem with WIFI is that hot spots are
very small, so coverage is sparse.

4. New Technology WiMAX
This new Technology would provide:-
That is less expensive than cable
Much easier to extend to rural areas
Broad coverage like cell phone networks.
 WiMAX is a wireless digital communications
system also known as IEEE 802.16.

5. Working
 There are two parts:
WiMAX Tower
WiMAX Receiver
WiMAX stations connect directly to the internet
with a wired connection.

6. TYPES OF WIMAX
FIXED WIMAX:
Fixed WIMAX
deployments do not cater
for hand off between
base stations, therefore
the service provider
cannot offer mobility.
MOBILE WIMAX:
Mobile WIMAX
implementations can be
used to deliver both fixed SAMSUNG MOBILE WIMAX DEVICES
& mobile services.

7. ADVANTAGES
Bandwidth Flexibility
Pricing + Contract Flexibility
Quick Installation
Interpenetration
DISADVANTAGES
WiMAX can operate at higher bitrates or over longer
distances but not both.
Omni directional antennas are used.

8. BROADBAND ACCESS
Many companies are closely examining WIMAX
for “last-mile" connectivity at high data rates.
The resulting competitions may bring lower
pricing for both home & business customers, or
bring broadband access to places where it has
been economically unavailable.

9. FUTURE
Anywhere, Anytime, Connectivity
Cost Effective
High speed of Broadband service

11. Mobile WIMAX Broadband

12. Conclusion
Within five years, we expect WiMAX to be the
dominant technology for wireless networking. By that
time it will be fully mobile, as well as providing low-
cost, fixed broadband access that will open up regions
where internet access has no far not been practical.
