In radio communications, what does simplex mode allow?

• A. Simultaneous two-way communication
• B. One-way transmission only
• C. Continuous connection
• D. Full duplex capabilities

Answer: (B)

In radio communications, simplex mode allows for one-way transmission only. This means that communication can occur in a single direction at any given time. A transmitter can send signals, but there is no capability for the receiving end to respond back simultaneously while the transmission is ongoing. This characteristic is important in scenarios where communication is often about sending broadcast information without the need for immediate feedback, such as in emergency broadcasts or certain types of public announcements. The other options describe different modes of communication. Simultaneous two-way communication describes duplex modes, while continuous connection and full duplex capabilities imply that both parties can talk and listen at the same time, which is not possible in simplex mode.
