Doesn’t work on any unlicensed frequencies. 2.4Ghz and 5Ghz are absorbed by water. Militeary submarines use VLF frequencies. With a mile long antenna. So tether is the only real practical method.
- jacquesm 4y agoNo idea why this got downvoted, it is 100% accurate.
- BugsJustFindMe 4y agoIt's not 100% accurate to say that tether is the only practical method. Untethered AUV/UUVs are quite common in the industry.
- yardie 4y agoPlease point them out. All the UUVs/AUVs I've found are either tethered to a buoy or completely autonomous and only transmit when the surface. In all practicality there is no completely untethered ROV on the market. Acoustic controlled UUVs are still line of sight.
- vbezhenar 4y agoWhat about sound?
- yardie 4y agoThey operate at 100s of bits per second not fast enough to transmit live video so your back to line of sight.
- BugsJustFindMe 4y agoAcoustic modems are indeed common in underwater applications.
