First TV White Space Database for Ireland

A preliminary TVWS database is now available for Ireland, here. This database has been created Spectrum Bridge using technical information which describes the Irish digital terrestrial TV system.

The database is also available as an App for iPhones or Android-enabled devices.

Spectrum Bridge has developed this tool to allow potential users and developers of White Space solutions to estimate the amount of available White Space that might be available after the transition to digital TV is complete in 2012.  The estimates do not guarantee the present or future availability of White Spaces.  The proposed rules, policies, implementation guidelines and underlying data are subject to change.  The tools offer some flexibility in adapting ACLR and C/I ratios to determine the potential effects of these parameters on availability.

However, these kinds of TVWS databases are emerging as the preferred spectrum policy tool to protect the incumbent TV services from new users of the TV frequencies. New wireless devices will likely be required to check such a database before transmitting in order to receive regulatory permissions.

This first estimate of Ireland’s TV White Spaces should serve to flag the potential of this shared spectrum opportunity.

TV White Spaces -Tech & Op Requirements Consultation

Main message from this post – two reports have been released for public consultation that relate to technical issues for uses of the TV White Spaces. Hence they may be of interest to this community. They are worth taking a look at – though we will post some points at a later stage.

What are they?

  • Draft ECC Report 185 “Further definition of technical and operational requirements for the operation of white space devices in the band 470-790 MHz”;
  • Draft ECC Report 186 “Technical and operational requirements for the operation of white space devices under geo-location approach”.

Where are they?

You have to go to this page and then download them. They are part of a longer list of reports on very many other things. Scroll down to Report 185 and 186.

Where did they come from? 

The 62nd meeting of WG SE has approved the two draft ECC Reports developed by SE43 for submission to the Public Consultation process. Yes a whole load of acronyms for those not from this space. The ECC (Electronic Communications Committee) is one of three autonomous business committees under CEPT (European Conference of Postal and Telecommunications Administrations) and is responsible for electronic communications matters. The ECC has working groups including a working group on Spectrum Engineering (SE) and SE 43 explicitly looks at White Spaces & Cognitive Radio Systems.

What should you do about them?

The  above reports will be in the public consultation phase until November 14, 2012. CEPT administrations as well as any other interested parties  are free to comment. There is a template online for comments which should be forwarded to Mr. Jean-Philippe Kermoal, ECO (jean-philippe.kermoal@eco.cept.org) by e-mail.

Embrace the New: Sharing Spectrum, Building Networks

Linda Doyle gave a talk at TEDxDublin on September 8th, 2012. Organised by Science Gallery as part of their HACK THE CITY exhibition, the event featured an array of speakers addressing a myriad of topics.

Linda’s talk addressed the advances in radios and networks that underpin many of the objectives of White Spaces Ireland. The talk gives an overview of the kinds of changes that are happening within radio technology and within the economics of ownerhip and consumption of spectrum and networks.

As the talk conludes, Linda notes that it’s time to Occupy Spectrum. To embrace the New.

Soundings on White Spaces

Luke Clancy, creator and presenter of Culture File [ @CultureFilePod ] on RTE Lyric FM was at Filling the White Spaces last week. He did a really nice piece on the event for Culture File which can be downloaded as a podcast from the here. What makes this especially great is the fact that Luke has brought the idea of white spaces to a very different audience. Radiowaves and issues around wireless communications are by their nature invisible to the wider public, while at the same time being part of their everyday lives. Culture File describes itself as the essential daily dose of arts, culture and play. Roll on the Spectrum Playground.

 

Filling the White Spaces

Our first event was the Filling the White Spaces event, hosted by CTVR and the Science Gallery on September 26th. Speakers from Adaptrum, BSkyB, Fairspectrum, Microsoft, Neul and Spectrum Bridge described the TV White Space Trials in which they were involved. The event was very well attended by a cross section of Irish Industry, academia and public service bodies. Details of the event including overviewpresentationsdiscussion notesdemos and photos are available on this site.
