Though it may have passed most of the international news channels by, the world's radio spectrum regulators and associated government departments and ministers have just signed away the results of the 2019 World Radiocomminication Conference (WRC-19) held in Sharm El Sheikh, Egypt. This 4 week long event is where international decisions on the use of the radio spectrum take place. Or at least that's the theory. All 'decisions' have to be driven by consensus, which means that everyone must agree and with so many divergent views on topics as wide ranging as more spectrum for 5G mobile services, to globally harmonising spectrum for railway communications, there is lots to discuss. There were around 20 items on the agenda for the conference.

Of particular interest to radio amateurs was agenda item 1.1, which concerned:

the allocation of the frequency band 50-54 MHz to the amateur service in Region 1

Radio amateurs have requested that the whole frequency range from 50 to 54 MHz is allocated to them on a primary basis in ITU Region 1 which is Europe, the Middle East and Africa. At present, in the ITU Radio Regulations, which dictate which frequencies are allocated to which services, 50 - 54 MHz is allocated to radio amateurs on a primary basis in Regions 2 (the Americas) and 3 (Asia/Pacific), and the idea was to align the band in every region. In Region 1 the frequencies are allocated to broadcasting as well as (in some countries) to radiolocation, land mobile and fixed (point-to-point) services, but not to radio amateurs (unless national administrations have unilaterally decided to allow them). Only in Botswana, Eswatini, Lesotho, Malawi, Namibia, the Democratic Republic of Congo, Rwanda, South Africa, Zambia and Zimbabwe does the band have any allocation to radio amateurs in the existing Radio Regulations.

Following the machinations at WRC-19, the radio amateurs have been granted a secondary allocation across Region 1 in the frequency range 50 - 52 MHz, with primary allocations in some or all of the range 50 - 54 MHz in a limited number of new countries. A secondary allocation means that the amateurs must not cause interference to any primary services (i.e. broadcasting and land mobile) and must accept interference from them, but it's a step forwards towards a global expansion of the 6 metre band.

This does not mean that the band will be available in each and every country immediately. First, each country's administration or regulator needs to update their national frequency allocation table to include the new band. This can take anything from a few months to a few years. There are still some countries who have not yet implemented the results of the previous WRC in 2015, despite it being completed 4 years ago. So don't hold your breath hoping to use the band when on holiday in Ouagadougou, it may be a long time before this new band is widely available.

The next task for the International Amateur Radio Union (IARU) who work tirelessly on behalf of radio amateurs at events such as WRC-19 is to deal with Agenda Items 1.2 and 9.1.2 of the next WRC in 2023. Agenda Item 1.2 is entitled:

to consider identification of the frequency bands ... 10.0-10.5 GHz for International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis... (N.B. this applies in Region 2, i.e. the Americas, only)

This includes a secondary Amateur allocation between 10.0 and 10.5 GHz, and a secondary Amateur-Satellite allocation between 10.45 and 10.5 GHz (as used by the already infamous Es'Hail-2 (a.k.a. QO-100), the first geostationary satellite with an Amateur radio transponder. Whilst the allocation of the band for IMT (5G) services does not preclude the Amateur service, in reality, a band full of a dense network of base stations and handsets would make it nigh-on impossible to be used for amateur radio and the band may be lost, in exactly the same way that the 2.3 GHz and 3.4 GHz bands were.

Agenda Item 9.1.2 is entitled:

Review of the amateur service and the amateur-satellite service allocations in the frequency band 1 240-1 300 MHz to determine if additional measures are required to ensure protection of the radionavigation-satellite (space-to-Earth) service operating in the same band...

The IARU will need to stave off pressure to remove (or otherwise reduce) the radio amateur secondary allocation on the frequencies 1240 - 1300 MHz (the 23 cm band) as it is claimed by the European Commission that amateurs may cause interference to their Galileo satellte navigation system. Not, it is worth pointing out, the everyday service used by smart phones and in-car sat-navs, but an additional service for specialist users.

The argument goes that there was once an amateur television repeater in the band which caused interference. Once - and it was resolved very quickly. But that is enough to raise concerns of potential wider future interference problems. The Commission therefore want to throw the amateurs out of the spectrum. The amateur allocation is secondary, so they must not cause interference, and so the Galileo service is already protected, but that is not always enough for everyone. The ITU giveth with one hand, and threaten to take away with two others. Was it ever any different?
