Working with Ofcom

Broadcaster information is now flowing smoothly at the UK spectrum regulator Ofcom thanks to a new database created by ATDI


ATDI won a contract to streamline its central database of all radio and television stations for the UK as well as international coordination. It was a task that required the melding of a disparate range of sources.
“For decades, Ofcom had been working with a variety of non-standard and ad hoc data sources. The main one of these was in the Microsoft Access format but others were contained in Microsoft Excel spreadsheets and as Ascii format files tables and, occasionally, text files,” says ATDI lead engineer Alex Krasnojen. “In addition, Ofcom works closely with the BBC and broadcast infrastructure company Arqiva and the three organisations use a database format unique to them – UKPM.”
The variety of data formats used by Ofcom made both internal and external data exchange an issue.
ATDI was tasked with unifying the information and presenting it in a standard, easily-accessible format. The basis for doing this was the company’s software tool ICS Manager. ICS Manager is in use by regulators worldwide to tabulate the abundance of details about the radio services. ICS Manager is tailored to the needs of the user, so ATDI engineers worked extensively to ensure Ofcom’s version of ICS Manager met the organisation’s requirements as closely as possible.
The result is that there is now a central Ofcom database which works with the different formats for the maintenance, processing and transfer of data. The database encompasses all Ofcom’s activities, processes, tasks and types of data. Its implementation has smoothed workflows and made each of Ofcom’s processes simpler and more efficient.
Alex notes: “Something very gratifying about this project is the degree to which we have been able to work and communicate with Ofcom. A situation like the one we found, with broadcaster information in various locations and in differing formats, was very complex. Our approach was to talk to Ofcom and identify a robust solution has been most pleasing on both sides.”


OFCOM (UK) Broadcast Spectrum Management Solution: ICS telecom EV + ICS manager

As EE continues to develop its 4G – LTE – network, its focus turns to operations in the 2.6 GHz band, where it needs to ensure its next-generation services for its mobile phone customers do not interfere with vital systems such as air traffic radars operating at 2.7 GHz.
Spectrum regulator Ofcom has produced an exacting framework for this process, seeking to guarantee both that safety is not compromised and that EE, which has committed huge resources to buying the spectrum rights and building its network, actually gets value for its investment.
As part of the framework, Ofcom is stipulating that not only must operators consider current radars but also future developments such as the migration of radar systems to S-band.
To help achieve this, EE has used ATDI’s flagship planning and modelling tool ICS telecom as well as the company’s 20 years of expertise in dealing with both the current situation and the one to come.
“There’s an element of politics here as well as engineering,” comments ATDI managing director Peter Paul. “EE needs its network to operate into the long term; air traffic controllers need radar to operate into the long term. Making those two imperatives sit together, particularly as radars move one at a time into the S-band, takes discussion and some diplomacy – as well as extremely precise modelling.”
A 4G/LTE signal has the power to saturate a radar receiver thereby rendering the system useless. To help customers avoid such problems, ATDI has built a new function into ICS telecom specifically tailored to the needs of EE and other 4G operators when trying to coexist with radars.
“The development of ICS telecom has been driven by customer needs since it was launched two decades ago,” Peter notes. “Everything in it now is of profound practical value to the people using it. That’s the wonderful flexibility of being a smaller company.”

HTZ warfare and ICS telecom introduce the Ofcom notice of coordination procedure required under spectrum access licences for the 2.6 GHz band


When planning its network deployment, the 2.6 GHz licensee must check whether
the protection thresholds set out in this document would be exceeded as a result of
any proposed 2.6 GHz deployment. To do so, the 2.6 GHz licensee will need to
calculate the communications signal and the out of band noise at the relevant
Protected Radar location(s) (see section 4). If these calculations show that the
relevant threshold(s) will not be exceeded as a result of the planned deployment,
then deployment can go ahead. If the calculations show that the relevant threshold(s)
would be exceeded as a result of the planned deployment, the 2.6 GHz licensee may
consider adjusting the deployment.
