I just came across this article.

http://apcmag.com/singapore-airlines...e-in-flight-calls-and-internet.htm

I am probably a bit late, like usual, but is this service already in operation on SQ or other carriers?

BA uses OnAir's technology on its A318s serving the LCY-JFK route, but only for inflight text and SMS capabilities, not voice calls. Access depends on whether your carrier has an agreement with OnAir -- in the United States, I believe that AT&T is the only provider with an agreement with OnAir. It also appears that the technology is available for use with GSM handsets only -- CDMA handsets are not compatible. Regardless, it's spendy and relatively slow: GPRS speeds for pricing similar to international roaming data, with is pretty expensive.

Air New Zealand are going to allow people to use Cellphones using OnAir technology on their new A320 (ZK-OAB).

Personally I don't really like this as I can definitely see myself getting annoyed if the person in front of me is yapping to her friends for the whole flight. Hopefully the high prices will stop that from happening often.

I agree that voice has little future on airplanes. We've been there, done that. It will not be the revenue generator which airlines are seeking. People are more willing to hold private conversations in public today than when phones were first added to planes, but I think the expense is going to be a huge factor just like it was before.

The question is will texting from cell phones on aircraft be used at a significantly higher rate. Personally, I'd take my granddaughter's cell phone away from her if she flew with us on a plane with these services. Might cost us as much as a new car by the time a long range flight landed!!!!

Apart from the fact if voice calls have a future or not does anyone know how reliable such a connection is?

I assume that sudden handovers take place between the land-based stations and the cell inside the airplae when the airplane ascends and descends. I work in this field and seen the speed and poor environmental conditions airplanes are subjected to, signal fading problems are enormous when the phone connects to a land-based antenna.

In fact the only technologies which handle these fading problems well are so-called OFDM/OFDMA based technologies. Newer communication systems like LTE,WIMAX and DVB-T make use of this technology precisely to handle these problems but this is not the case for GSM or CDMA.

I am just curious how fast an A320 or B737 decelerates in flight, descends banks or chances direction in normal conditions?

Won't happen on a US flag airline. We have gone before congress and all but blocked the thought from their minds.

But it isn't actually illegal, so I dont see why that matters.

The FAA doesn't require cell phones to be off in flight. The FAR requires that 800 mhz devices the "digital cellular" band not communicate with the ground in, it says nothing about devices in the PCS band (1900) or any of the other available allocations.

Since just about every cell phone sold in the US today can do the PCS band, if not several others, it should be fine. The carriers can waive the FAR for portable electronic devices and that would cover it.

At any rate the onboard coverage is either via an onboard base station or with specific ground based systems, the rapid handover is not an issue.

However all US based Flight Attendant groups have gone before Congress to fight any thought of Cell phone use inflight.

Then Congress would need to pass a law and the president would need to sign it.
