range?
[edit]I was curious as to the range of this technology. And, maybe, bandwidth. I realize the answer is probably 'it depends'. But just some ballpark numbers would be really interesting... can you send voice communications 100 feet? 1000 feet? 10 or 100 miles? I have no idea and the article gives no clues, other than that diagram of a sub and a ship. OK so we know it probably works over 100 or 1000 feet. Example (i'm making this up cuz I dont' know):
The biggest factor in quality of transmission is the water current present at the time. During WW2, the JX99, a US navy sonar system between ships and subs, could carry 2-way voice communication 2000 to 3000 meters if the current was under 5 knots. Above 30 knots, distance was reduced to 250 meters, and above 50 knots, no communication was possible.
More recently, multi-transducer systems have allowed voice channels up to 10,000 meters, or 300kbps telemetry 2000 meters. —Preceding unsigned comment added by OsamaBinLogin (talk • contribs) 21:43, 17 March 2009 (UTC)
Ranges of 8 to 10 kms have been practically achieved and such systems are in use. the systems are designed fore more ranges but practically ranges above 8kms are rarely achieved--- girish — Preceding unsigned comment added by 27.54.188.44 (talk) 17:47, 17 January 2013 (UTC)

Merger proposal
[edit]- The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.
- Quiet consensus assumed. Result:Merge. Alan Islas (talk) 13:51, 27 August 2020 (UTC)
I propose to merge Underwater telephone into Underwater acoustic communication. I think that the content in the Underwater telephone article can be better explained within the larger context of Underwater acoustic communication. Underwater telephone is a very short stub and can be easily incorporated here. As a stand-alone article it struggles to meet notability and has other issues as well.
