Broadband Wireless Access (BWA) technologies provide high-speed communication access by wireless means to consumer and business markets. The most common example of BWA is Wireless LAN, but efforts are intensively continuing to deliver ubiquitous broadband network access by deploying adequate radio technologies like Metropolitan Area Networks, Cellular Networks, Radio LANs and Wireless Personal Area Networks (WPANs) which can even be combined in one single device to ensure seamless operation.
Broadband Wireless Access is also an attractive option to operators in areas that do not have a wired access network available. Savings in speed of deployment and in installation costs will ensure that interest in BWA standards continues.
Our Role & Activities
Broadband Wireless Access includes a large variety of radio technologies and corresponding services therefore several ETSI technical committees are active in this area:
Broadband Radio Access Networks (BRAN)
ETSI technical committee BRAN prepare and maintain Harmonized Standards for RLANs operating in the 5 GHz frequency band (EN 301 893), for Broadband Fixed Wireless Access (BFWA) using the 5,8 GHz band (EN 302 502), for White Space Devices (WSD) operating in the TV broadcast band (EN 301 598), for WPAN systems operating in the 60 GHz frequency band (EN 302 567) and for Broadband Direct Air-to-Ground Communications (EN 303 316 and EN 303 339). If new frequency bands are allocated to BWA communications then ETSI TC BRAN will most probably work on corresponding Harmonised Standards.
EMC & Radio Spectrum Matters (ERM)
ETSI technical committee ERM is responsible for the Harmonised Standard covering 'Wideband Data Links operating in the 2,4 GHz band', i.e. Radio LANs or Wireless LANs (EN 300 328). This standard is very widely used for demonstrating the conformity of Wi-FiTM, and similar licence-exempt data communications equipment with Directive 2014/53/EU.
Access, Terminals, Transmission & Multiplexing (ATTM)
The Working Group TM 4 of ETSI technical committee ATTM is responsible for specifications for point-to-point and multipoint radio systems in the fixed service, used in core and access networks, covering all equipment aspects including antenna parameters. These specifications address many frequency bands within the range 1,3 GHz to 86 GHz for point-to-point radio systems (EN 302 217-2) and 3,5 GHz, 10 GHz and 26 GHz for multipoint radio systems (EN 302 326-2).
Other Technical Committees
The following ETSI technical committees also work on specifications that can be used for Broadband Wireless Access:
- Digital Enhanced Cordless Telecommunications (DECTTM)
- Rail Telecommunications (RT)
- Third Generation Partnership Project (3GPPTM)
