Nextel has the direct connect walkie-talkie service.
The idea is to add the locator that is low range say 5 miles in radius. This locator will show the direction from where your buddy is calling (Only if enabled by him). This will be helpful in malls, crowded city locations, etc.
This feature will
be on the cell phone and what it shows is the direction and distance of the caller. If the tracking option is turned, it continuously monitors the distance and direction so that you don't miss each other narrowly.

I think you'll find that in order to get direction you'll need to use triangulation - having more than one receiver. You could, however, have a low-quality indicator of distance if the broadcasting strength is known. |

If you both have mobile phones, why don't you just call your buddy and ask where he is? |
|
| |
See link for a very similar concept (I would say a redundant one). |
|

no, these ideas are differnt. this one is a directional finder ranging 5 miles. and the other one is non directional and limited to a mere 50 feet. |

Oh, be serious. If trivial details like that could make an idea different, we'd have 100,000 duplicate ideas on here (most of them involving car tail-lights). |

Trivial details like that do, in some cases, make ideas here different. I've never fully understood the whys and wherefores of it, but that's why I leave MFDs to moderators. |

Just remind everyone that "Buddy List" is a registered trademark of AOL in the United States, that should cut down on its use via lawsuit-phobia. (MFD removed). |

If U speak Spanish and live in Europe, this site will locate your buddy if he has a mobile phone switched on: http://www.step.es/personales/jms/localizador/localizador.htm |
