Wireless data transmission equipment, as the hub for information exchange between base stations and various mobile targets, is an important component of the entire vehicle dispatch. Its selection options include the following:
-Public network devices: GSM, CDMA, CDPD (wireless data public network)
-Cluster communication: such as 350M and 800M cluster systems used in public security
-Conventional radio station: using dedicated channels and wireless MODEM
Of course, some vehicle dispatch systems may not have communication systems, such as long-distance freight companies, which do not require real-time monitoring and scheduling, mainly determined by the application purpose of the system.
The key to choosing a suitable wireless data transmission device is to balance the following points:
1. Transceiver conversion time: It is directly related to the system capacity and is the first consideration when selecting a data link
Some high-end digital radio stations have a conversion time of only 10-20ms; The conversion time of conventional voice radio stations is generally longer, requiring 100-200ms;
2. Access method:
Network mode: The dispatch center is connected to the wireless communication network through a dedicated line, which has a large system capacity but high operating and construction costs. It is the only choice when establishing a large monitoring network.
Single machine mode: The dispatch center is connected to the communication network through wireless transceivers, which has a small system capacity but convenient expansion. Adding wireless transceivers can increase the system capacity, which is widely used when the system capacity is not large, and the construction and operation costs are relatively low.
3. Collision handling:
Conventional radio station: The information transmission of the terminal should achieve time division multiplexing and fully utilize frequency resources
Clusters and public networks: Communication systems allocate frequency resources for terminal information transmission requests
