UK Amateurs Losing Access to Part of 2.3 GHz and 3.4 GHz Bands
15-04-2014
ON4AVJ
UK telecommunications regulator Ofcom has announced that it’s ending Amateur Radio access to significant portions of the 2.3 and 3.4 GHz bands.
The action, announced on April 7, came in the wake of a year-long “consultation” — a rule making proceeding — that involved the release by the Ministry of Defence of 40 MHz of spectrum at 2.3 GHz and 150 MHz of spectrum at 3.4 GHz. Amateur Radio is secondary on the bands.

Amateur Radio will lose privileges on frequencies in the two bands that overlap with spectrum that Ofcom plans to award for “new civil uses” — 2350 to 2390 MHz and 3410 to 3475 MHz. The announcement gives radio amateurs at least 12 months’ notice, but radio amateurs must comply immediately with procedures to avoid interfering with other users; ham radio occupants of 2310 to 2350 MHz will have to register their use and provide details to Ofcom.

Amateur Radio will retain access to the adjacent bands, but Ofcom has put procedures in place to remove even those frequencies from Amateur Radio access, if necessary in the future. Ofcom said earlier this year that with military and other government use of the 2.3 and 3.4 GHz spectrum ending, “we believe an award of the spectrum for high power use is likely to deliver greater benefit to UK consumers and citizens than continued amateur use.” Ofcom was required by the Ministry of Defence to adequately protect its systems from Amateur Radio interference in both the released spectrum and in adjacent bands.

“The MoD’s plans are part of a government commitment to release 500 MHz of spectrum by 2020,” Ofcom explained in its order. “This commitment to opening up spectrum for new civil uses is based on growing demand from UK consumers for spectrum-hungry devices such as smartphones and tablets.” Ofcom said that use of mobile data devices more than doubled in the 18 months leading up to January 2012. “Indeed, the 2.3 and 3.4 GHz bands are identified in Ofcom’s ‘mobile data strategy’ as having the potential to support even better mobile data services for citizens and consumers in the coming years,” the regulator said.

Ofcom said it was making 2300 to 2302 MHz available for amateur use, but licensees first must obtain a Notice of Variation to their licenses. Hams in the US have secondary access to 2300 to 2310 MHz, 2390 to 2450 MHz, and 3300 to 3500 MHz. — Thanks to RSGB, Ofcom

The final Ham Video Commissioning Pass 4 is planned Sunday April 13 at 18.23 UTC.

Configuration 4 will be used:
  • ARISS antenna 43
  • Frequency 2395 MHz
  • Symbol rate 2.0 MS/s
Koichi Wakata will operate OR4ISS.
Ground stations F6DZP and IK1SLD will receive the signals and stream the video over the BATC server.
The video is expected to be received during 5 minutes.

This will mark the end of the Blank Transmissions.

We thank the operators who filed reception reports of blank transmissions. Your participation to the Ham Video testing campaign has been invaluable.

No decision has been taken yet on the future use of Ham Video. We will keep you informed on any progress.

  • ARISS antenna 43
  • Frequency 2369 MHz
  • Symbol rate 1.3 Ms/s
Reports on reception of blank transmissions are very welcome. Reports can be filed via this webpage: http://www.spaceflightsoftware.com/ARISS_FSTV/submit.php.

Participants using the Tutioune receiving software can record as well as stream detailed parameters of the received signal. Please see: http://www.vivadatv.org/.

Reports are available at http://www.vivadatv.org/viewtopic.php?f=66&t=294&p=785#p785.

Thank you for your participation to the Ham Video testing campaign.
