Actually all cells can send and receive signals. For example every cell has a CD95(FASr) which receives signals from natural killer cells or T cells and results in cell death. Also all cells send signals through cell membrane receptors to neighboring cells. These signals prevent neighboring cell colonies from growing too big.(The lack of these signals is one of the problems with certain cancer cells)
no.
Mobile phones transmit and receive date and calls in the microwave section of the radio spectrum.
Yes they do. Mobile (cell) phones transmit and receive radio signals in the microwave portion of the radio spectrum.
The medical term for root-like structures of a nerve that receive impulses and conduct them to the cell body is "dendrites." Dendrites are specialized extensions of nerve cells that branch out to receive signals from other neurons and transmit these signals to the cell body for processing.

Receptors are proteins on the cell membrane that are used to receive signals
Neurons transmit and receive signals in the nervous system
Half duplex communication means that a system may transmit and receive signals, but not at the same time. It has to switch over from transmit to receive, and vice-versa. Think of an analogy of a walkie-talkie; when you press the transmit button you cannot hear or receive a message until you release the transmit button.
Dendrites: Unlike most axons, they receive signals from other neurons and pass the messages to the cell body of the neuron. Axons transmit impulses away from the cell body toward the axon endings/ terminals
