MMX: Microwave Modem Transceiver
Welcome to the MMX project site
The MMX project aims to design and build a radio modem, operating in the 5.8 GHz amateur radio / ISM band. The system will provide the physical and link layer components upon which a network protocol can be run (for example, TCP/IP).
The design goals for the system are to provide a (relatively) simple, open, robust and low cost basis for the development of ad-hoc point-to-point links to be deployed in local, metropolitan and rural broadband applications. Schematics and design documentation will be available to the public in order to foster interest and invite community participation in the field of microwave radio.
By designing for operation in the shared ISM / amateur radio band, the system can be deployed by end users. Operating at 5.8 GHz requires careful electronic design to mitigate problems due to radiative effects and the nonlinear behaviour of circuit components at high frequency, but avoids the noise of the 2.4 GHz band and takes advantage of some favourable licencing conditions (at least in Australia) at that frequency.
