I am looking for a under water wireless communication, distance up to 3000 meters. For this I quickly did some research on it and found out that Acoustic communication would be the best solution since they travel longer distance under water. I found these modems from EvoLogics (link)
I would like to know what are the things I need to keep in mind before I start making such communications. What can be the major problems on these type of communication or during the communication setup? I can already imagine of something that can cause problem which is the wave of the water if the water is not still, this can carry away the wireless modem which will result in lost of communication. Is there more things that can make the communication difficult?

Any of the underwater acoustics companies would be able to advise on likely performance and potential problems with a bit of detail about your application, typical considerations (as others have noted) include:
If you add more details about your application, you might get more specific advice about the real-world problems you might face, for example can you give a little bit more information on:
There are a number of suppliers of equipment, targeted at a range of applications, from modem suppliers through to acoustic positioning and control (off the top of my head, these include Kongsberg, Nautronix, Sonardyne, Linkquest, Evologics (in no particular order!)). Each optimises performance for their application area so there isn't a list of 'major problems' that you can consider, each trades off one limitation for another.
[Disclosure, I work for one of the above companies, but I'm confident there's nothing in this answer which any of the others would disagree with]
