Ofcom consults on Mobile Communications onboard Aircraft
Thursday 18 October 2007 13:10:37 by John Hunt

Ofcom has released a consultation today on the introduction of mobile services on aircraft that are registered in the UK. The current proposals see the introduction of GSM (and GPRS) in the 1800 MHz band, with a possible extension to further technologies such as 3G if it proves successful. Much work is occurring in Europe to try and introduce Mobile Communications onboard Aircraft (MCA) and the choice for GSM was made initially as it is a widely incorporated standard, with almost all European mobile phones being compatible. European wide standards are expected to be introduced which each member state will have to take on board for their own implementations.

Previously, restrictions were in place that limited the roll out of MCA based on safety concerns with regards interference with aircraft's communication and navigation systems, as well as interference to ground based mobile networks. Work has been taking place in this area with the EASA (European Aviation Safety Agency) granting the first airworthiness certificate for MCA to the Airbus 318 in June 2007.

The technical implementation of such a system is based around a pico cell located onboard the aircraft (with a leaky feeder antenna) utilising a satellite backhaul to link the service back to the ground network. The airline would operate the radio license for the service, and arrange suitable agreements for interconnection with the terrestrial mobile networks. Tariffs to the end user are likely to be higher than existing mobile calls and roaming charges due to the increased cost of running the system.

MCA will not be available for the entirety of a flight. Due to interference with ground based networks, the Electronic Communications Committee (ECC) has stipulated that the absolute minimum height above ground level for any transmissions should be no less than 3,000 metres, although in practice this may be set higher.

Several airlines have pre-announced plans to launch MCA, and it is a significant step forward in making communication ubiquitous. The proposals set out a starting block which will allow people to access mobile Internet based services from virtually anywhere in the world. With the possibilities of extension into higher speed services available via 3G, people will be able to make use of time in flight to get on with business as usual.

Would this not open up moe opportunities for terrorists?

Err ok and if that myth they tell us is true whats to stop an 1800 MHz single interfering with other aircrafts is the same airspace???

you sir, are an idiot.

Errr if im an idiot so must be the trained pilot of 30+ years that taught me to fly 5 years ago, because according to him any wireless signal from something like a mobile phone (which BTW 1800mhz is what many operate on) can not only affect the aircraft instruments you are on but also others around it... I always suspected what he and other flight officials etc say was BS and this confirms it.

Makes you think a bit eh!!

1) During 9/11 hundreds of phone calls where made from planes without this technology (FBI has them all on tape including the famous "Hello Mom, it's Mark Bingham here"

2) Not one of the planes crashed or had problems due to the phone calls

So why the need to spend fortunes on technology when it was working fine on aircraft over 15,000ft over 6 years ago

My point exactly Pigmaster :) personally it just stinks of yet another ofcom get their nose in the news to make it look like they are doing us all a favour type story.

All the mobile calls made from the 9/11 aircraft were on the older analogue (AMPS) system and at low altitude. GSM1900 was still in it's infancy in 2001 as it took the USA a long time to find out GSM was a superior land based system despite not working in low level aircraft. All cellular phone systems depend on frequency re-use and antennas that limit their area of coverage by tilting down from the horizon. Very little RF goes vertical and even at low altitude there will be a lot of co-channel interference due to the mobile receiving from distant cells on the same channels.
