Which option is NOT listed as a dispatch method?

• A. Hard Wired
• B. Data Link
• C. Microwave Link
• D. Cellular Network

Answer: (D)

Dispatch methods are the communication channels designed to deliver urgent information reliably and without relying on public networks. Hard wired is a physical, dedicated connection like copper or fiber. Data link refers to transmitting data over a controlled link, and Microwave Link is a fixed wireless, line-of-sight connection used for point-to-point dispatch. A Cellular Network, while widely used for everyday communications, depends on public cell infrastructure, introduces variability in latency and availability, and is not typically listed as a standard dispatch method in systems designed for dependable, prioritized dispatch. So cellular network is the option that is not listed as a dispatch method.
