Speed through the air is becoming a growing imperative as ATDI helps both a mobile network and commercial flights reach maximum potential.
Network operator EE has now developed its tri-carrier LTE-Advanced structure to the extent that a demonstration was conducted at Wembley Stadium at the end of February delivering more than 400 Mbps. The system has been built using ATDI’s flagship planning and modelling software ICS Telecom to ensure it does not interfere with air traffic radars operating in the 2.7 Ghz range; EE’s LTE-Advanced utilises a combined 20 MHz of 1800-MHz spectrum with 20 MHz of 2.6-GHz spectrum, and another, separate 15 MHz chunk of 2.6-GHz spectrum. The 1800MHz band does not affect radars.
“Clearly, it is imperative that EE gets value for its investment by having a network that works for its customers and nobody needs telling how important it is to have air traffic control radars operating without interference,” notes ATDI operations director Paul Grant. “EE’s use of ICS Telecom has been an integral part of ensuring both those things happen. Indeed, EE is continuing to take technical support from ATDI to make certain its engineers are getting the most out of ICS Telecom’s 2.6GHz coordination feature.”
The LTE-Advanced signal has the power to saturate a radar receiver thereby rendering the system useless. Many of the air traffic control radars have now had filters installed so possible interference areas are limited to areas close to the radar head.
EE’s Wembley Stadium demonstration created what the company called an interactive gig experience involving an audio-visual installation featuring multiple 4K and HD screens and high-quality audio streaming.
Aeronautical functions in ICS telecom:
Multilateration (multi-ranging / passive)
RADAR (monostatic, bistatic, multistatic)
RADAR coordination (2.6 / 3.4 GHz)
