Transmitters and receivers for use in hybrid networks capable of supporting time-reversal division multi-access communication protocols are described. Wireless access points include a wireless receiver for receiving a wireless channel probe signal from a device and a wireless transmitter capable of supporting a time-reversal division multi-access (TRDMA) protocol and at least one other wireless communication protocol. A controller is used to control the operation of the wireless transmitter. Wireless terminal devices include a wireless transmitter for transmitting a wireless channel probe signal and a wireless receiver capable of supporting a TRDMA protocol and at least one other wireless communication protocol. A controller is used to control the operation of the wireless receiver. An example of the at least one other wireless communication protocol that may be supported is OFDMA. Network performance can be improved by using wireless access points and terminal devices that switch between supporting one wireless communication protocol or another or supporting multiple wireless communication protocols simultaneously.
