Industry Specification Group (ISG) on Millimetre Wave Transmission (mWT)

Chairman: Renato Lombardi, Huawei Technologies (UK)

Facilitating the use of the 6 - 42 GHz and 50 - 300 GHz bands for large volume backhaul and fronthaul applications to support mobile network implementation, wireless local loop and other services that benefit from high speed wireless transmission.

The deployment of 4G, the future needs of 5G and the number of connections required for massive machine-type communications in the Internet of Things are making unprecedented demands on radio access networks and backhauling.

Millimetre wave bands (30 - 300 GHz) offer enormous amounts of under-utilized bandwidth – as well as more spectrum for radio transmission than lower bands, and wider channel bandwidth, with fibre-like capacity. As a source of largely untapped spectrum resource, millimetre wave technologies are expected to be a major enabler of future mobile communications. 

In 2018 our Industry Specification Group (ISG) on millimetre Wave Transmission (mWT) published a Group Report analysing spectrum, license schemes and network scenarios in the D-band to facilitate deployment of high capacity backhaul systems and decongest heavily-loaded networks.

Much of the group’s attention focused on exploring how microwave and millimetre-wave backhaul could meet the requirements of 5G deployment. Building on a previous white paper, our Group Report on 5G Wireless Backhaul/X-Haul gained extensive industry and media interest.

In the final stages of preparation in 2018, another Group Report provides a performance management overview, detailing metrics needed to describe the error performance related aspects in radio equipment.

It is anticipated that communication links in the V-Band will be used for access and transport applications, including street level connectivity, urban/suburban fixed broadband residential access and business connectivity. We thus published a Group Report presenting a 3D ray-tracing interference analysis based on an urban scenario.

In 2018 the group made preparations for a successful SDN Northbound Interface PlugestTM event, carried out at ETSI in January 2019.

Look out for in 2019 – ISG mWT work in progress:

  • Group Specification (GS) on Definition of a Wireless Transport Profile for Standard SDN Northbound Interfaces
  • Group Report (GR) on FS RF frequency ranges above 174,8 GHz
  • GR on current status of standards and activities in RF bands above D-band
  • GR on W-Band - Performance Management overview, covering metrics needed to describe error performance related aspects in radio equipment used for FS
  • Miscellaneous Work Item - survey of E-Band deployments and status of international and national regulation worworldwide
