Adverts and promos sent direct to your mobile might seem like a spammer's dream but Cambridge group OnMyMobile want to make sure consumers keep control of what they receive with opt-out services.

The OnMyMobile system uses small servers with a local area network connection for uploading and downloading files. These servers could be plonked anywhere from shops to bus shelters and work over distances of up to 10 metres.

The system will only send out messages to people who have spent a certain amount of time gazing into a shop window and works on any network or handset.

The picture shows a mock-up of a cinema. The mobile phone user wanders past and can find out information about what's on and whether the film is fully booked, as well as downloading video clips of the flicks they want to see.
