VoIP On A/C, Would It Work

With the concerns of of cell phones and wireless electronics on board an A/C, with a service such as Conexion by Boeing or using the phones as an internet access point, would VoIP pose any threat to communications? If it doesn't, wouldn't the F/A's probably not know what it is and ask you to turn in off anyway. If it is possible with something like Conexion, I am sure airlines wouldn't want you getting around their expensive phone services...

I can't recall exactly, but I think I read it in a magazine (Business Traveler?) about someone using VoIP and it working very well. I will post a link if I find it.

Best,

I dont care if it works and doesnt interupt service, people talking on phones on a plane are still going to piss mee off and the majority of the passengers off too.

From a technical standpoint, the main problem is latency. I'm not talking about bandwidth (how much data can be pushed through in a given time period) here. Latency == response time, or the time it takes for interactive data to make a round trip (an example being ping time). For instance, streaming video is highly dependent upon bandwidth but not so much on latency. Web surfing is moderately dependent upon bandwidth and moderately dependent on latency. Voice doesn't require much bandwidth at all (using H.323 or SIP) but because it's real time, needs low (fast) latency. Any time your aircraft broadband goes through satellite, or even multiple terrestrial hops, latency can be an issue.

I used a program called Paltalk on an SK flight last week. It is a webcam/voice chat program. It did pretty well with the limited bandwidth. It took a little while for the people in the room to figure out where I was. It kinda blew their mind.

You can use Skype with a webcam if your aircraft has Connexion on it.

I don't think it will piss people off - do you hear people complaining about other passengers talking in flight? You can't hear them above the engines normally anyway.

I would however object to cell phones ringing in flight - that noise would drive me up the wall!

I've used skype out on an LH flight to and from Japan with a laptop and headset, latency was not an issue. Our flight was running late and I called home to let them know. With a headset you don't shout and the call is made at low volume levels, only the person next to you would know you are calling. As long as it is used with consideration for other pasengers there's no problem. The other question is do the next generation cell phones, which are WLAN compatible, work with Connexion?

I've used both Skype and Vonage over Connexion. I was in Business and First classes and didn't need to raise my voice to be heard. There was no indication that any other passenger could even hear me, let alone be annoyed -- except one teenager sitting next to me whose comment was "totally cool!"

Latency was quite noticable -- about 2 to 3 seconds return trip. It was useful to say "Over" at the end of each transmission, though not essential.

I have used SKYPE a number of times on SQ LHR-SIN/SIN-LHR. Works great. I didn't notice any latency problems at all.

Sounds very interesting and I think could become the next big thing with travellers once more people discover onboard internet and VoIp. I don't think the voices would bother me at all because it would be just like someone talking to someone else on the plane except without the other person, which would be in fact quieter than a conversation on the plane.

I agree about the low latency, but the requirement for low latency comes from the codec used (e.g. G.729a, etc) as opposed to the call control protocol used (e.g. H.323, SIP, MGCP, H.248, et al).

I'm glad to hear that the airlines are not using filtering to block VoIP calls.

If this was my teenager I would hope you'd be thrilled that there are such nice, enlightened and polite young adults out there. Your comment was not thoughtful nor considerate that there are just as many irritating adults on aircraft in First and Business Class.

I don't see why you would want to use 729. Bandwidth is not an issue in the case of Connexion, so 711 would be fine. As long as the latency is under 150ms, you should not notice a degradation in voice quality.
