Ofcom WRC-15 Consultation Responses

Logo WRC RA 2015The RSGB report responses to the Ofcom consultation on WRC-15 prepared by the Society and affiliated groups including AMSAT-UK are now available in the WRC-15 Special Focus section.

In addition to supporting Agenda Item 1.4 for a 5MHz allocation, the detailed responses cover amateur radio interests across several VHF and Microwave allocations. This includes amateur bands affected by other agenda items, ITU procedures for nano- and pico-satellites, and preferences for future agenda items that may be proposed for WRC-18.

IARU position on nanosatellites and picosatellites Resolution 757

IARU_LogoDuring a teleconference in mid-May, the IARU Administrative Council authorized the distribution of a paper which sets forth the IARU positions on the agenda items that will be considered during the World Radiocommunication Conference in 2015. The agenda items that impact amateur radio and amateur-satellite services including the IARU position on each of those agenda items have been published in the IARU E Newsletter for May 29, 2013.

Agenda Item 9.1.8 – Regulatory aspects for nanosatellites and picosatellites (Resolution 757 (WRC-12))

Resolution 757 calls for the results of studies of the procedures for notifying space networks that presently apply to nanosatellites and picosatellites to be reported to WRC-15. Because of the possible implications of these studies for the amateur and amateur-satellite services, the IARU is following the progress of these studies attentively. Nanosatellites and picosatellites that are properly licensed in the amateur-satellite service and are operated consistent with the purposes of the amateur and amateur-satellite services as defined in Nos. 1.56 and 1.57 may utilize the provisions of Resolution 642.

Ofcom 2400 MHz Consultation

AMSAT-UK_Bevelled_LogoThe UK communications regulator Ofcom has published a call for inputs relating to spectrum use by licence exempt devices in the 2.4 GHz band. 2400-2450 MHz is an ITU Amateur and Amateur Satellite Service allocation.

The Ofcom announcement says:

This band is close to radio spectrum in the 2300 MHz band, which the Ministry of Defence (MoD) plans to release for new civil uses.

The MoD has therefore commissioned work to audit licence exempt uses in the 2400 MHz band, in particular to identify the full range of possible uses of this spectrum. The call for inputs introduces two audit reports that explore licence exempt use in the 2400 MHz band.

It also invites stakeholders to identify any other uses that may need to be considered to understand any technical coexistence.

The public consultation closes on June 19, 2013.

ARRL 9 cm Band Plan Updated

Outside of ITU Region 1, the Amateur Satellite Service has a 9cm band allocation of 3.400 GHz – 3.410 GHz on a non-interfering basis. No current satellites are active on this frequency range at present. The new band plan reserves allocations for EME and amateur satellite operation.

The detailed graphic of the 9 cm band plan and accompanying article is posted on the ARRL web at:

In ARRL Bulletin 14 ARLB014, released on June 5 the report reads:

The ARRL Board of Directors has unanimously voted to approve the 9cm band plan, as presented by the ARRL UHF/Microwave Band Plan Committee. Earlier this year, the committee asked radio amateurs for comments on a proposed 9 cm band plan, explaining that the purpose of these band plans is to share information about how the amateur bands are being used and to suggest compatible frequency ranges for various types of application. The committee also recognized that local conditions or needs may necessitate deviations from a band plan, and that regional frequency coordinating bodies may recommend alternatives for use in their respective regions.

The new 9 cm band plan includes the following notations:

* This band plan includes all other emission modes authorized in the 9 cm amateur band whose necessary bandwidth does not exceed the suggested bandwidths listed.

* Weak Signal Terrestrial legacy users are encouraged to move to 3400.3-3401.0 MHz, as time and resources permit.

* Broadband segments may be used for any combination of high-speed data (e.g. 802.11 protocols), Amateur Television and other high-bandwidth activities. Division into channels and/or separation of uses within these segments may be done regionally, based on need and usage.

* Per ITU RR 5.149 from WRC-07, these band segments are also used for Radio Astronomy.  Amateur use of these frequencies should be first coordinated with the National Science Foundation.

A global Amateur-Satellite Service allocation at 3400-3410 is one of the objectives of the IARU.

Nano and picosatellite resolution at WRC-12

RA-WRC-12-LogoWouter Jan Ubbels PE4WJ provides an update regarding the attendance by ISIS at the World Radiocommunication Conference.

At the conference, ISIS has managed to write a last-minute resolution which was submitted by a group of countries, led by The Netherlands. The aim of this resolution is to propose an agenda item for the next WRC (2015), which proposes to conduct studies to identify the spectrum needs of nano-and picosatellites, and furthermore to study the associated regulatory constraints. After the discussions at the WRC, the resolution got partially accepted by the conference (only the regulatory aspects will be studied), and not for the WRC-2015 but for the WRC after that, which will be in 2018. The provisional final acts of WRC2012 has been published, I quote:

“2.2 to consider the appropriate regulatory procedures for notifying satellite networks needed to facilitate the deployment and operation of nano- and picosatellites, in accordance with Resolution COM6/10 (WRC-12); ”

TIES users can download the provisional final acts at http://www.itu.int/md/R12-WRC12-R-0001/en

This is very good news, and could mean that the ITU notification process for nano and picosatellites can become greatly simplified in the future. We first of all would like to thank all the supporting administrations for their support and would like to invite the community to, through their administrations, participate in the studies, so that the outcome will be as much as possible line with the needs of the community.

We will continue to work on this subject and keep you updated through these lists and at the various small / nano / picosatellite conferences and workshops.

kind regards,
