A variable data rate wireless transmitter configured to receive input of data from a plurality of input channels and transmit at least some of the data over a variable data rate wireless point-to-point communication link, wherein portions of the data are associated with priorities, and the wireless transmitter is configured to change transmission of at least some of the portions of the data, based, at least partly, on the priorities associated with the portions of the data, and on a data rate configured for transmitting the portions of the data over the variable data rate wireless communication link. A variable data rate wireless receiver configured to receive data over a variable data rate wireless point-to-point communication link, including a delay compensation buffer configured to maintain a substantially fixed delay between input of the data into a wireless transmitter transmitting the data and output of the data from the delay compensation buffer, by maintaining a suitable output rate of the data from the delay compensation buffer. Related apparatus and methods are also described.
