A communication system comprising a base station and two or more terminals configured for communicating with the base station by means of a communications protocol, wherein: the communications protocol operates in a frequency band to which unlicensed access is permitted and the terminals are configured for unattended operation with the base station. The system can be used to enable utility meter readings to be communicated back to a base station over the unlicensed white space frequency band (400 to 800 MHz), usually used for television broadcast. The system can also be used for Machine Type Communication or Machine to Machine Communication (MTC or M2M). |
