Wireless communication system
First Claim
1. A wireless transceiver, comprising:
- an antenna;
a re-transmitter connected to the antenna, the re-transmitter incorporating a modulator; and
a data processor including a data sink and a data source, the data sink being connected to receive signals from the antenna and the data source being connected to the modulator to provide modulation of data onto re-transmitted signals.

Abstract
An apparatus to facilitate wireless communication where one side of the link is designed for ultra-low power consumption. The apparatus comprises two types of transceivers: a full function transceiver (called the “Controller”) and a reduced function transceiver (called the “Terminal”), which are normally connected in a “star” network configuration (i.e. several Terminals communicating with one Controller). The Controller communicates with Terminals directly using chirp signals which contain the modulated data to be transmitted. The Terminal communicates with the Controller by re-transmitting “carrier” chirp signals which have been sent to it by the Controller. In this way the Terminal does not generate any of its own RF signals, thereby reducing its power consumption. The Terminals may not communicate directly with each other, only indirectly through the Controller.

6. A method of wireless communication between transceivers in which the transceivers include at least a controller and a terminal, the method comprising the steps of:
-
the controller transmitting signals to the terminal according to a protocol;
the terminal processing the signals in a re-transmit mode and a data processing mode;
in which, in the re-transmit mode, the terminal modulates and re-transmits signals received from the controller; and
in the data processing mode, the terminal demodulates signals received from the controller. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
