Broadband Wireless Access (BWA) technologies provide high-speed communication access by wireless means to consumer and business markets.
License exempt Wireless Access Systems including Radio Local Area Networks (WAS/RLANs) represent the primary BWA technologies used for wireless internet access. With billions of devices already in operation, and the rapid growth expected to continue for the foreseeable future, and the demand for greater throughput to support Gigabit internet access and advanced wireless applications, the current spectrum allocations are insufficient to maintain an acceptable level of performance users are accustomed to.
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 prepares and maintains Harmonised 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), for WAS/RLANs operating in the band 5 925 MHz - 6 425 MHz (EN 303 687) and for Wideband Data Transmission Systems (WDTS) for fixed network radio equipment operating in the 57 GHz to 71 GHz (EN 303 722). 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, 26 GHz, 28 GHz, 32 GHz and 42 GHz for multipoint radio systems (EN 302 326-2). Consideration for the introduction of other bands, newly allocated or made available to fixed service use, is routinely carried on, as appropriate.
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)
