High Frequency Standardization
Figure 1 shows the trend of the use of higher frequency bands by the
fixed radio transmission systems, which is illustrated by the release
date of the RF frequency arrangements by the ITU-R F Series
Recommendations.
In 2012, ITU-R F series recommendation about the radio-frequency
channel and block arrangements in the 71-76, 81-86 GHz bands
(ITU-R Recommendation F.5B313), and 92-95 GHz band (ITU-R
Recommendation F.5B307) were adopted. Moreover, ITU-R Report
that covers up to 134 GHz (ITU-R Report F.2107) was approved in
2011.

High Frequency Standardization
Figure 2 shows the channel spacing trend for fixed radio transmission systems. This is
illustrated by the approval dates of RF frequency arrangements in the ITU-R F Series
Recommendations.
Prior to 2002, the maximum channel spacing has been 220 MHz in 18 GHz-band. In 2012,
the radio-frequency channel and block arrangements in the 71-76, 81-86 GHz bands (ITU-R
Recommendation F.5B313) the allocated channel spacing is about 5GHz enabling multi-
gigabit data transmission per channel per link.

Within a Macro area O2
absorption does not protect
Average attenuation for the band 57 – 63 GHz
In rare situation with highly congest
dense environment, attenuation
due to O2 absorption may not be
enough if parallel links use shared
frequency channel. Such situation
should be avoided with the aid of
radio links planning.

mmW Transmission industry still in its
early phase
Big investments necessary to deploy new
features, new frequency bands
Products ranging from
Enterprise level to Carrier-class
Still high costs from lack of key components
Timid and unclear strategy for mmW deployment, still in
evaluation of the technology and small volume deployment
lack of confidence
mmW spectrum not regulated yet, with very different
licensing approaches (even in countries with strong
microwave tradition)

Agenda
Millimetre Wave (mmW) background: Spectrum & Industry
ToR of millimetre Transmission (mWT) ISG
Planned Initial WIs and deliverables
Motivation of ETSI mWT ISG
The mWT ISG aims to facilitate the use of the V-band (57-66
GHz), the E-band (71-76 & 81-86 GHz) and in the future higher
frequency bands (from 50 GHz up to 300 GHz) for large volume
applications in the back-hauling and front-hauling to support
mobile network implementation, wireless local loop and any other
service benefitting from high speed wireless transmission..
ToR of the mWT ISG
mWT is intended to address the whole industry value chain with particular
emphasis on:
• Current and future regulations and licensing schemes for the use of suitable
spectrum in different countries
• Putting in communication the whole industry chain to share and circulate
public information regarding the applications in field in order to favor faster and
more effective decisions on investments needed to provide new technologies,
features and equipment
• Influencing standards for the deployment of the products
• Enhancing the confidence of all stakeholders and the general public in the use
of millimeter-wave technologies
ToR of the mWT ISG
The purpose of the ISG mWT is to provide a platform and opportunity for
companies, organizations and any other stakeholder involved in the microwave
and millimeter-wave industry chain to exchange technical information as follows:
• Sharing pure technical information (i.e. on trials aimed at propagation channel
model verification, interference simulation,..) in order to prepare White Papers
and Presentations to increase the level of confidence by the operators
worldwide in the use of millimeter-waves and
• Making it possible for all stakeholders involved in the industry to obtain the
latest technical information including latest research results, promoting
cooperation and technical progress but always avoiding commercial issues and
always under compliance with the relevant competition laws.
The ISG mWT aims to be a worldwide initiative with global reach.

Agenda
Millimetre Wave (mmW) background: Spectrum & Industry
ToR of millimetre Transmission (mWT) ISG
Planned Initial WIs and deliverables
mmWave Transmission Forum: high priority topics
1. 60 GHz band regulation: the very fragmented approach in terms of spectrum allocation
and licensing model (despite it’s unlicensed band) is preventing small cell backhaul
applications in some Countries
2. Enhance the confidence in the use of millimetre-wave technologies: sharing the
amount of information derived by trials and early roll-outs on E-band regarding
propagation impairments and availability calculation methods can improve Operators
confidence
3. Definitions of key requirements for most important transmission applications:
macro backhaul, small cell back-haul, front-haul, etc.
4. Identification of most suitable (target) mmW bands for most important transmission
applications
5. ……
Initial planned WIs and deliverables
Following list of initial deliverables has been identified as a high priority for the ISG mWT but is not meant to be exhaustive.
White paper on the 60 to 95 GHz bands regulation: Survey of the actual deployments and the status of international and national regulation worldwide. The result would be presented in a white paper. A live database may need to be maintained and updated on a regular basis.
White paper to ‘Enhance the confidence in the use of millimetre-wave technologies’: sharing the amount of information derived by trials and early roll-outs on V-band and E-band regarding propagation impairments and availability calculation methods which can improve Operators confidence.
Technical report ‘Define the relevant use cases of mmW Transmission’. In this report key requirements for most important transmission applications shall be identified.
Technical report to ‘Identify the most suitable (target) mmW bands in relation to most important transmission applications’.
