yes, it will depend on physical characteristics of the water and strength of the signal. thus, a large antenna is required. read Prospects and Problems of Wireless Communication for Underwater Sensor Networks, Liu et al, 2008
Attenuation
Attenuation distortion is the distortion of an analog signal that occurs during transmission when the transmission medium does not have a flat frequency response across the bandwidth of the medium.
Attenuation occurs in all copper cable regardless of whether it is twisted or not. This is because the copper atoms actually 'resist" the electrical voltage being applied (a physics principle).
Attenuation
It is the loss of data from the coaxial cable during transmission .
Water affects the travel of radio frequency in terms of attenuation. For example, sea water has high attenuation, causing communication hardly possible.
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.
6 dB is a "good" attenuation.
We can reduce attenuation effects bt using repeaters
breast attenuation correction meethods
Attenuation means the reduction of signal strength during transmission. If one is looking for information about attenuation, it can be found on the Wikipedia website.
Because race car.
Water
when water is your ear
How can hot water be frozen - where does this happen?
longer cable lengths have greater signal attenuation
