First Cellphone Use On Airplane Given OK

s31523 writes "With over 1 billion cell phone users worldwide, and with so many business travelers, using the cell phone on the airplane has been a recent hot topic. Emirate airlines is announcing they will give the OK for cell phone use on their planes, making them the first airline to do so. The FCC and FAA still ban the use, but are working to determine safety implications, if any."

Issues are technical, not just regulatory

Let's ignore the issues of cellphones interfering with the flight controls. We'll ignore that search for a random cellphone on some oriental airline long ago, purported to be messing up the landing.

From what I understand, cellphones work by associating themselves with "cells" of coverage. The closer they are, the less power they use, and so on. When the user moves cells, the network switches them over to the new cell.

From the air, a cellphone will see many, many different cells as being equally good. It will also have to switch across cells much faster than normal. Without the plane itself acting as a roving cell tower for the occupants, it seems to me that this would cause a lot of problems. Not only will all the cellphones be transmitting at full power, but the network will potentially have to handle many many more switches cell to cell, and faster than normal. There's evidence of this from TFA when it said some upscale, long-haul airlines are installing equipment onboard that will allow for cell phone use.

I'd love to hear from anyone in the business that could shed more light on these technical issues, and whether they are as big of a problem as I suspect if airlines were to just say "Sure! Use your phone!"

Not exactly news, but CNN thinks so

Emirates said months ago that they were going to add this service, which uses an on-board picocell and relays calls very expensively very satellite. Should run at least US$2.50 per minute for calls. I wrote about this in The Economist back in September (not Emirates news): RyanAir will launch in-flight calling by the second half of 2007 on hundreds of its planes. That will be the first major deployment.
