The intricacies presented by the underwater environment are far more compared to the terrestrial environment. The prime reason for such intricacies are the physical characteristics of the underwater environment that have a big impact on electromagnetic EM signals. Acoustics signals are by far the most preferred choice for underwater wireless communication. Because high frequency signals have the luxury of large bandwidth BW at shorter distances, high frequency EM signals cannot penetrate and propagate deep in underwater environments. The EM properties of water tend to resist their propagation and cause severe attenuation. Accordingly, there are two questions that need to be addressed for underwater environment, first what happens when high frequency EM signals operating at 2.
View Full Version : 2. Has anybody tryed the new 2. The theory says that with this change in order of magnitude higher in freq the penetration should be lowered.
Pages:  2. Using radio control underwater. Hello, I am trying to control a RC submarine under 2 meters of clear water or very slightly salted, much less than the sea. I would need to send about three servo channels at least four times per second, plus three binary channels bps at the very least I tried a 2. The range is about 10cm underwater I expected worse , then the signal drops.
