INTRODUCTION



• WiMAX stands for Worldwide Inter-operability for Microwave Access.

• A wireless metropolitan area network (MAN) system.• The technology is based on the Institute of Electrical

and Electronics Engineers (IEEE) 802.16 standard. • 802.16-2004 is often called 802.16d, since that was the

working party that developed the standard. It is alsofrequently referred to as "fixed WiMAX" since it has nosupport for mobility.

• 802.16e-2005 is an amendment to 802.16-2004 and isoften referred to in shortened form as 802.16e. Itintroduced support for mobility, amongst other thingsand is therefore also known as "mobile WiMAX".

• A 4G (Four Generation) technology.



HISTORY



• In 2001, the WiMAX forum was established to market

and promote the 802.16 standard. There they coined the

term WiMAX (Worldwide Interoperability for

Frequency plan



BENEFITS of

WiMAX



• Wireless

• Long range• Low cost

• High bandwidth

• Tow types of service

• Can provide service in remote place

• Flexible

1. Non Line-of-Sight

2. Line-of-Sight



LIMITATION of

WiMAX



• Obstacles can reduce the range.

• To provide WiMAX service there is need of moreelectricity.

• For cellular connection there is need of special

types of mobile like Wibro.



CONCLUSION



• BTRC held an open tender last year on the 24th of

September for WiMAX license.

• From June 2009 WiMAX is going to be launched in

Bangladesh.

• WiMAX is going to be a dynamic provider of

communication to link distant places.• Our country holds many prospects, what is required is to

understand the technology and utilize them in the best
