Technology

WiMAX

Full Name

Worldwide Interoperability Microwave Access

Description

A wireless digital communication system projected for Metropolitan Area Network (MAN) as a packet-switched system.

Origin/Facts

Intel Corporation introduced the silicon chip which formed the core of WiMAX technology. This provided equipment manufacturers and carriers the ability to deliver next-generation wireless broadband networks around the world.

Unit

Data Rates

Uplink : 70Mbps(Max)
Downling : 70Mbps (Max)

Services Offered

1. High Data rates
2. Quality of Service (QoS)
3. Security
4. Mobility (VoIP)
5. Scalability

Range

Provides broadband wireless access(BWA) up to 30 miles in fixed stations and 3-10 miles to mobile stations.

Frequency/Channel

WiMAX operators with the following frequencies have been reported, from around the world:
2.3GHZ
2.5 GHz
3.3GHz
3.5GHz
5.8GHz

Advantages/Disadvantages

The speed and reliability of WiMAX makes it a true mobile broadband

Advantages:
It's More secure than either fixed WiMAX or 3.5G
Better coverage
Fixed WiMAX provides a wireless alternative to cable and DSL for "last mile" broadband access
Mobile WiMAX provides portable connectivity.
One of the significant advantages of WiMAX is spectral efficiency. Disadvantages:
Spectrum issues have yet to be overcomed.
A few technical issues, especially with regard to security regulations for mobile WiMAX also exist.
Available bandwidth is shared between users in a given radio sector, so performance could deteriorate in the case of many active users in a single sector.

Present/Future in SAMENA

The future of WiMAX is bright and will evolve around a mixture of fixed broadband alternatives, especially in regional areas and, with added mobility, as a 4G technology. WiMAX will become part of a number of networks, providing broadband wireless access in rural areas, offering backhaul services, offloading data traffic and making broadband mobile.
WiMAX revenue could grow from $21.6 million in 2005 to $3.3 billion in 2010.
Intel Asian broadband campaign is helping to set up WiMAX trials in South-east Asia to help fight poverty and hunger, and to achieve universal primary education.
