In dispatching centers it is common for eight or more radio base stations to be connected to a single dispatching console. Dispatching personnel can tell which channel a message is being received on by a combination of local protocol, unit identifiers, volume settings, and busy indicator lights.
It should also be borne in mind that one cannot possibly define everything. At some stage in the definition process the words used in the most basic definitions have to be taken as undefined — or in other words, they have to be understood intuitively.
AUTONOMOUS CARS CAN DETECT SURROUNDINGS USING A VARIETY OF TECHNIQUES SUCH AS RADAR, LIDAR, GPS, ODOMETRY, AND COMPUTER VISION. ADVANCED CONTROL SYSTEMS INTERPRET SENSORY INFORMATION TO IDENTIFY APPROPRIATE NAVIGATION PATHS, AS WELL AS OBSTACLES AND RELEVANT SIGNAGE.
Professional base station radios are often one channel. In lightly used base stations, a multi-channel unit may be employed. In heavily used systems, the capability for additional channels, where needed, is accomplished by installing an additional base station for each channel. Each base station appears as a single channel on the dispatch center control console. In a properly designed dispatch center with several staff
members, this allows each dispatcher to communicate simultaneously, independently of one another, on a different channel as necessary. For example, a taxi company dispatch center may have one base station on a high-rise building in Boston and another on a different channel in Providence. Each taxi dispatcher could communicate with taxis in either Boston or Providence by selecting the respective base station on his or her console.
