ATDI 4G CONTEST awards ceremony has been successfully accomplished at Universidad Rey Juan Carlos (Fuenlabrada) de Madrid.

 

With the full support of of Universidad Rey Juan Carlos, the excellent presentations of Mr. Ignacio Urrutia, Gerente Service Demand Management from Orang and Juan Perdro Fernandez Cuartero, vocal de la Junta del Gobieerno del COIT, the awards ceremony has gained an overwhelming responses from all participants.

ATDI is proud of this competition which helps engineering students open their first page of career and make more possibilities on the use of 4G network femtocells.

Special thank to Javier Ramos, Director of Telecommunications Engineering school from the Universidad Rey Juan Carlos I, whose premises was held, also attended, during development, the presence of representatives of the French and Finnish embassies and Fanny Bergé, the photographer.

Digital dividend in Brazil (700 MHz for new 4G mobile services)

BIG COUNTRY, BIG PLANS

ATDI is helping to expand the burgeoning Brazilian economy with a plan that will enable people to watch television and talk on the phone at the same time.

Brazil is planning to re-use its digital dividend 700MHz frequencies for new 4G mobile services. These will be in a band adjacent to existing television signals and ATDI has been tasked by the GSMA, which represents the interests of mobile operators worldwide, to plan and model the re-shaped spectrum usage to identify and mitigate potential interference issues.

“Terrestrial, free-to-air television is particularly significant in Brazil given the country’s modest uptake of cable and satellite services. A lot of people would be at risk of being very unhappy if we had been anything other than entirely accurate in our planning and modelling.”

A complicating issue is that analogue television had to be factored into the equation due to the envisaged long transition to digital.

“It has been a very challenging but very rewarding task.”

ATDI has now delivered a report which examines ways to mitigate interference between the proposed new mobile signals and the existing and planned television services. It presents a number of options for ensuring clear signals including filtering and minimising TV transmission powers in channels immediately adjacent to LTE services.

“The advent of fourth-generation mobile services globally has meant we have now conducted this kind of survey and report in places from the mountains of north Europe to the icecaps of Iceland to Brazil, It is exciting to know we can develop techniques that work no matter what the terrain, the climate or the population density.”

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.”
