with a range of electricity, gas and water meters and
transmit wirelessly to eliminate installation costs.
To design a means of communicating over a PSTN to relay
data back to a central server
To provide trends analysis software to interpret results for
loyalty and marketing use. To create a user interface to report power usage and for
suppliers to advertise ‘buy now' low price power tariffs
based on client usage profiles

MLE Value AddODM 3
Ability to research and reverse engineer protocols used in
several utility meters; designing a bespoke V22 modem that can be used over a
PSTN to reduce cost and offer an OEM solution and using an
innovative processor-based power supply design to achieve low standby operation and long battery life.
