Abstract

One of the key characteristics of the traditional Citizens Band (CB) radio system was that it was a location-based public information service. Due to the limited transmission range the user would inherently only hear other users who were physically close to their location. This enabled many users to use the same radio channels since only a limited number were ever within the same radio range and it meant that the information being shared who location relevant to the same group of users, for example a highway accident, etc. The problem is how to simulate this same geographically based system using a cellular device. The proposed solution is to utilize a centralized chat server that could track the location of mobile devices running the chat application based on cell tower location and/or GPS enabled device. This location could be updated on a time or a change of location basis. Users would send a message to the central server which would distribute that message to other users who were within "range." The range could be a user-selectable parameter based on a circle around their current location. Messages could be either text-based or recorded voice-based. An interesting option would be to offer the user the ability to select any location. This would enable a user to listen to chat sessions happening in their old home town, or many miles down the highway for example.
