摘要： Detection of a locomotive or other vehicle is enhanced by transmitting an RF alert signal from the vehicle when the vehicle approaches a heightened alert area such as a railroad crossing. The RF alert signal is received by communication unit(s) carried by pedestrian(s) or residing in vehicle(s) approaching the heightened alert area, thereby providing an alert that supplements train whistles, gates, horns or other warning mechanisms known in the art. The RF alert signal may also be transmitted to infrastructure devices such as logging devices. In one embodiment, the RF alert signal is transmitted from a locomotive upon detecting operation of a train whistle associated with the locomotive and/or coincident to receiving an external alert signal or automatic vehicle location (AVL) information indicating that the locomotive is near a heightened alert area.

摘要： A method and apparatus for simulcasting within a communication system is provided herein. During operation, each base site will be equipped with a plurality of radios capable of transmitting on various frequencies. Base sites within the communication system will be capable of communicating on a predetermined number of channels, which may differ among base sites. A number of channels will be shared by the base sites. When a simulcast is desired, the participants are located, and a common channel is determined for communication. Thus, call participant location information is used to determine the best channel to use to meet the group's coverage needs.
摘要翻译：本文提供了一种在通信系统内同时广播的方法和装置。在操作期间，每个基站将配备有能够在各种频率上发射的多个无线电装置。通信系统内的基站将能够在基站之间可能不同的预定数量的信道上进行通信。基站将共享一些频道。当需要同时播放时，参与者被定位，并且确定通信的公共信道。因此，呼叫参与者位置信息用于确定用于满足组的覆盖需求的最佳信道。
