Over the years, I've come up with many oddball ideas.
The idea I had most recently was of a Networked Radar Detector. The Networked Radar Detector would not only detect radar and laser but have GPS and Bluetooth connectivity.
What it would do is, when radar or laser is detected, it communicates this to other people's Networked Radar Detectors via the wireless telephone network. Obviously, you'd need a Bluetooth-enabled mobile phone.
For example, if you were traveling down I-12 eastbound and you are detecting Ka Band, this would be relayed to other NRD users down the road behind you and ahead of you. Their units could say something like "Ka detected 5mi".
You could be able to configure the detector to alert you only if the other detector's alert meets your criteria, for example, you could set it so you only get a network alert if the signal is "x" strong. You could select how far of a warning you'd like (e.g., 5mi, 10mi, etc...) If such a detector were to have a feature similar to the "Truelock" on the new Escort unit, it would not only block out the false signal from your detector but it would filter out network alerts, too, provided that it meets the same criteria (frequency and GPS coordinates.)
Such a device would have caveats, though. If you were going over an overpass, for instance, and you detected Ka ahead, then the detectors in the cars passing underneath would get a warning, too. If it were possible to determine from which direction the signal was coming from, then the warnings could be delivered based on GPS data. Additionally, it'd be worthless unless there was enough users out there to make it worthwhile. I'd imagine something like this would be expensive to make plus there'd have to be some type of monthly fee for the network alert feature in addition to requiring a mobile phone.
Well, that's the idea. What do you think of it?
