An underwater RF signal propagation path is created by utilizing a
plurality of individual RF transceivers such as MEMS RF transceivers.
Each MEMS RF transceiver has a predetermined buoyancy. A stream of the RF
transceivers are released to form a line of RF transceivers underwater
such that the individual RF transceivers have an RF transmission and
reception distance greater than the distance between the RF transceivers
whereby an RF signal can be repeatedly retransmitted down the line of RF
transceivers.
