Singapore, 25 February 2005
In a nutshell, wireless broadband access (WBA) is an access technology which offers high-speed data access over the air. In other words, high-speed connectivity anytime, anywhere.
In today's market, there are various technologies offered for the provision of wireless broadband access (WBA) services operating in both licensed and license-exempt frequency bands.
Generally, WBA can be divided into two broad categories:
The leading fixed wireless broadband standard and technology today is IEEE 802.16-2004 endorsed by the WiMAX Forum. WiMAX or World Interoperability for Microwave Access Forum, is an organisation set up by industry players to promote the deployment of fixed broadband wireless access by using a global standard IEEE 802.16. WiMAX is also chartered to certify the interoperability of WBA products and technologies.
Other fixed WBA offerings include proprietary technologies such as those developed by SOMA Networks.
Mobile WBA can be used for the delivery of both fixed and mobile broadband services.
The mobile WBA market as it stands today is highly fragmented. A mobile WBA standard has yet to be finalized by the industry. Leading companies involved in developing mobile WBA technologies include ArrayComm (iBurst), Flarion Technologies, IPWireless, Navini and Samsung.
The 4 primary groups working on a mobile wireless broadband standard are: UMTS-TDD (also known as WCDMA-TDD), 1x EVDO, WiMAX (802.16e) and 802.20 (MobileFi) (Source: Arthur D Little Mobile Broadband Wireless Report 2004).
For a compilation of the various fixed and mobile WBA technologies in the market today, please refer to the attachment. Information gathered here have been gathered from various sources such as industry reports and vendor websites for this quick snapshot of WBA technologies today.
