Bandwidth usage

I going to be deployed soon to Afghanistan.  While away I wanted to use roll20 to continue running a campaign for my daughter.  The problem is that both connections will likely be satellite connections.  It isn't so much how fast the connection is, but rather the limits on how much can be sent for a given month.  Can roll20 handle a low bandwidth option?  I see you can do text, but I'm concerned I guess about how the maps work and how much data is being sent back and forth.

I have played roll20 over my phone's data plan which has a 5MB allotment and depending on what is used, you should be ok. I would recommend reducing the number of graphics used (aka don't use several hundred tiles and tokens per map page but one map and only a handful of tokens or go theater of the mind style) and do not use camera. I would be assuming you are using voice but text would be a lesser amount of data sent.

Thanks, I really appeciate the reply. 

Actually, of your plan, how much do you think you used...per hour say?

I really don't know as I didn't track it but I never exceeded my monthly allotment. I came close a few times but those times were when I used voice also. I ran text games and was lite on the number of tokens and maps (I mostly used an image for the scene only and occasionally used a battle map for combat if it was going to be complex).

I monitored a few of my own game sessions once, and a 3 hour game ran an average of about 60mb. But most of that was because we use Ventrilo for voice. If you go text only, you won't use nearly that much. Do you know where you'll be stationed? If you are staying in Bagram, you should be good. Anywhere outside of that, who knows. I spent most of my time at a remote COP in eastern Afghanistan. We had satellite through some "local" provider, but it was super slow. And super expensive. You could browse the web, but that's about it. When we were processing out of the country and moving through BAF, they had a subscription-base internet provider there that was pretty decent. 

The thing limited most by a slow/bad connection is voice and video. If you play a text-only game, you shouldn't have any problems at all.

Roll20 itself uses no more data then is required to download the images used, unless you voice/video/jukebox. I've used more data browsing the web then playing here. I would suggest using a different voice client such as ventrillo, mumble, discord, or teamspeak, as they only transmit data when you speak instead of constantly and depending on which you choose can control the bandwidth of voice data. The lag time can get annoying at times and you will probably end up speaking over each other, but be patient and it will work.
