WiMax is a wireless technology that provides broadband connectivity over long distances at speeds up to 70 Mbps. It operates between 2-66GHz and can connect users within a radius of 50 km. Pakistan has seen significant adoption of WiMax, with the largest network operated by Wateen Telecom covering over 17 major cities. Key benefits of WiMax include long range, high speeds, low cost of deployment compared to wired networks, and ability to provide connectivity to remote areas. While interference and lack of widespread adoption present challenges, WiMax is projected to become a dominant wireless technology for connectivity within the next 5 years.

2. What is Wimax?
 Worldwide Interoperability for Microwave
Access
 Wimax in simple terms is wireless broadband
access.

Allows communications over long distances,
covers approximately 50 km.

Operates on frequencies between 2-66GHz

Transfer rate of 70mbps.

3. “Wimax is actually not a technology,but
rather a certification mark,or ‘stamp of
approval’given to equipment that meets
certain confirmity and interoperability tests
for the IEE802.16 family of standards”.

4. WiMax Forum
• It is a non-profit industry body dedicated to promote
the adoption of wimax.
• It ensures that different vendors’ products will
interoperate.
“WiMAX Forum Certified™ means a service provider
can buy equipment from more than one company and
be confident that everything works together”

9. Working

10. Working of WiMax
•
Wi-Max works similar to Wi-Fi
– Use radio signal to send data from one computer to another
– Offers higher speed
• WiFi provides 54 Megabits per second
• WiMax provides up to 70 megabits per second
– Covers long distance
• WiFi range 100 feet.
• WiMax range 50 Km
– More number of users
– Availability of internet at remote areas
•
Supports two type of connections
– Frequency Division Duplexing(FDD)
– Time Division Duplexing(TDD)

11. Parts of WiMax
• WiMax system consist of two parts
– Transmistter
• Wi-Max tower is used to transmit data and can cover
up to 3000 square miles
– Increased range is due to frequency and power
– Weather and large buildings can effect coverage
– Receiver
• Receiver could be a small box or build into a laptop
• Encrypted data keys to prevent unauthorized users
from stealing access.

12. Two types of transmit/receive
• Non-Line-of-sight
– Device on our computer connects to the tower.
– Uses low frequency range 2 GHz – 11 GHz.
• Line-of-sight
– Operates at higher frequency (66 GHz).
– Data is sent from pole to pole using a
microwave link
– It is strong , stable and without errors

23. Benfits of WiMax

24. Benefits of WiMax
• Long Range
The most significant benefit is its range which is 5 miles (NLOS) 30
miles (LOS) which can cover up to 3000 sq miles (enough to blanket an
entire city)
• Cost Effective
WiMax is an high speed broad band, so no longer have to rip up
buildings or streets to lay down expensive cables
•
High Speed
It can provide 70Mb/s enough bandwidth which can support more than
60 businessess at once. Also supports thousand homes at DSL speed
connectivity

25. Benefits of Wimax
• Quick Deployment
As no wires need to be laid Wi-Max can be easily deployed.
• Service
It provide two wireless services
Non Line-Of-Sight
Operates at 2 to 11 GHz reverse compatible with existing Wi-Fi
technology.
Line-Of-Sight
Can go as high as 66 GHz since signal is more stable and strong
which leads to greater bandwidth.

26. Problems of WiMax
• Hesitancy
Companies are hesitant to use Wi-Max base station it has not reach
to widespread use yet.
• Research and development
In order for Wi-Max to succeed New products must be researched &
developed to incorporate Wi-Max.
• Interference
Other wireless electronics can interfere with Wi-Max connection and
some time cause reduction in data throughput

27. Future of WiMax
• Future looks bright in remote areas and specially in
China.
• The biggest market of Wi-Max is in China. Chinese
government making Wi-Max as a national standard for
fixed broadband wireless access at 3.5GHz.
• Wi-Max will become the dominant technology for wireless
networking within next 5 years, by 2009 industry anlayst
project that WiMax market worth between 3 to 5 billion$

28. Future of WiMax
• Intel produce chips embedded with Wi-Max technology
and they also stated to introduce Centrino laptop
processors in next 1or 2 years.
• In Pakistan, Wateen telecom has announced WiMax
(fixed wireless service) covering more than 17 major
cities of Pakistan.
•
In short, Wi-Max opens the doors to numerous services
and All developing countries could take advantage of this
efficient, cost effective technology.
