This might be out of the realm of common knowledge, but I figured I'd ask anyway.

I know that most of the ship is blanketed with WiFi and that you can use that connection to access the internet on a pay-per-minute plan. My question is, does Celebrity limit clients who are connected to the access points from talking to one another?

The reason I ask is that we've got a large group going on a cruise next year, most of whom work in IT. Assuming the WiFi network permits internal communication, we can use our cell phones to communicate over the network peer to peer without needing internet or actual cellular coverage.

I don't have any personal experience with such a request, but I'd wager the onboard IT manager will say no, since it's only his/her job to be responsible for paying customers using the Internet, not folks who want to use the ship's wifi to communicate peer-to-peer.

I'll bet he or she could come up with all sorts of implausible scenarios in which your activities would mess up Internet access for everyone else -- for example, what if you spend hours a day videochatting between cabins! ;^> Not that you'd do anything like that, but all he or she will care about is the risk.

Well, the point would be not to be paying. Generally those type of networks are set up to keep people from getting out without paying, but not to regulate internal traffic. This just may not be answer we can get until we get there and try.

I think you may have misunderstood the OP's question, which hinged on the fact that the scarcity onboard isn't Wi-Fi per se but Internet bandwidth. Ideally, p2p traffic onboard would reflect that.

Montesn, give it a try! Maybe the IT manager will be in a charitable mood.

I wouldn't expect their IT manager to bend any rules on this. Basically either their network is totally locked down or they've only put thought into stopping people from getting outside the network and using their satellite internet. Either way, it either works or it doesn't, but it's not something we'd involve the staff in.

it would depend on how you were billed if you could log onto the network and not send traffic thru the WAN you would probably not be billed but I am not sure how you would talk with the phones you would need a walkie talkie type program since instant messaging goes back thru a server.

The company I work for makes software like that. I'd just have to have it loaded on a laptop. Assuming the network allowed internal communication, phones would just talk to the laptop.

I'm curious ... how would you communicate between phones within you group, using WiFi? Skype? Sounds like a great idea which our small group of six could try after we leave Hong Kong in April.

What I think it really comes down is whether the ship network has been configured with each connection getting its own stub subnet and unable to "talk" to the other subnets. I have not been impressed with the sophistication of Celebrity's IT group so I suspect they have not done that. And their concern seems to be protecting revenue streams, not each client. But, as said by others, it will have to wait for you to test it.

When is your cruise and on what line? I'd be courious to hear if it worked. I was thinking of trying out something similar by installing openfire, an xmpp server, on my laptop in the cabin, and xabber, an xmpp client, on mine an my wife's phone that connected to the server on the laptop. I think this will require their routers to assign an ip that starts with 10. so all connections can recoginize others no matter what router on the ship they are connected to, and to have the routers name be the same throughout so that you don't have to manually connect to wifi on the phone every time to move to another area.

I was able to test this in a hotel that had 2 routers and an ip that started with 10. The routers had different names though so it would be a pain if the ships routers have different names.

As far as I know you will have a few problems:

The use of the wi-fi network on the ship is limited to accessing the internet. You are billed at $0.75/minute for all minutes you are logged onto the system regardless of the amount of data, if any, being transmitted.
They almost always have access blocked to VOIP programs such as Skype and even if access wasn't blocked the internet bandwidth access speed is so slow that the connection probably wouldn't work in any event.

NCL has announced an experimental program that would allow phone to phone communications over their wifi system. But I read they are just planning on putting it on one ship as a test and don't know if it is up and running yet or not. so maybe some day.....

I tried to do this with my devices on our carnival cruise last December, I couldn't see the other devices on the ships wifi. I tried both a walkie talkie app, as well as setting up my own ventrillo server, no dice, the network is locked down, which is good, cause you don't know what virtual noro virus your computer might get. ;-)

I did see today that carnival is beta testing something that will do text messaging as well as walkie talkie functions on the breeze. I have also read that NCL and Disney have something similar available.

I was able to perform the previously stated message that I posted on the carnival breeze that I was on several weeks ago. In a nutshell, I had openfire, an xmpp server, on my laptop in the cabin always running and connected to their wifi, and xabber, an xmpp client, on my wife and I's phone that connected to the server on the laptop by specifying the ip address that my laptop was using. The only draw back was that when I was in an area of the ship that I was never in before I had to manually connect my phone to the wifi, but after the first time it would automaticly connect.

Dave...I'm curious if you had to pay to have your laptop/server connected to the wi-fi system. Also...did you happen to hear from anyone else using the Carnival Fun Phone App being tested on the Breeze? Or have any idea how much they were charging to use the app?

I will be going on the allure in Oct and will be bringing an iPad, 2 iPhones and a laptop. My experience on a previous cruise was that the Access points on the ship do not allow devices connected to them to communicate with each other. It is something that the access point can be configured to allow or not.

But I will see on the Allure if this does work. I am interested to see if it does.
