Abstract

A modular wireless communications platform is provided. The modular wireless communications platform has a modular host unit and a modular remote unit in communication with the modular host unit. The modular host unit and remote unit include a serial radio frequency communicator configured to convert serial digital data into RF sampled data and configured to convert RF sampled data into serial digital data. The modular host unit and remote unit also include an interface coupled to the serial radio frequency communicator and configured to allow transfer of the RF sampled data from the serial radio frequency communicator to a digital to analog radio frequency transceiver module.

Claims
