WRC 2019 Agenda Item Details

Agenda Item: Agenda Item 1.1
Resolution(s): Resolution 658 [COM6/6] (WRC-15)
Description of work:

This agenda item relates to consideration of an allocation of the frequency band 50-54 MHz to the amateur service in Region 1, in accordance with Resolution 658 [COM6/6] (WRC-15) which resolves to invite the 2019 World Radiocommunication Conference to consider the results of the studies below and take appropriate actions, including spectrum allocation, with the ITU-R to study spectrum needs and sharing with the mobile, fixed, radiolocation and broadcasting services.

The ITU-R is invited to study:

  1. the spectrum needs in Region 1 for the amateur service
  2. taking into account the spectrum needs, study sharing between the amateur service and the mobile, fixed, radiolocation and broadcasting services
Comments: The Resolution notes that there is an allocation to the amateur service in Regions 2 and 3 and this AI would assist in promoting harmonization while protecting existing services in Region 1. The AI deliberately does not say whether the allocation be primary or secondary.
Lead Working Party(s): WP 5A
Involved Working Parties: WP 3K, WP 3M, WP 5B, WP 5C, WP 6A
How Visualyse products can help: Visualyse Professional can model sharing between amateur services and the mobile, fixed and broadcasting services to ensure they are protected from allocation to amateur services. This analysis can be static, area, dynamic or Monte Carlo including adjacent band studies. A range of propagation models could be used including Hata / COST 231, P.1546, P.1812, P.2001 or generic dual or triple slope.
How Transfinite consultants can help: We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at ITU-R Working Parties. Using our in house Visualyse Professional we can quickly model a very wide range of systems, services and scenarios.
