Question: In Mission Critical Data (MCData) services, as per 3GPP specifications, what is a characteristic of the Short Data Service (SDS) capability for message transmission?
Option 1: Messages can only be sent over the media plane, ensuring lower latency.
Option 2: The MCData service allows messages to be transmitted over both the signalling plane and the media plane.
Option 3: Only text-based messages are supported with a maximum payload of 1000 bytes.
Option 4: Location information of the sending MCData user cannot be included in the message payload without explicit user consent.
Explanation: This is correct because the SDS capability within MCData services is designed for flexibility and reliability, allowing messages to utilize either the signalling plane (for more control and guaranteed delivery) or the media plane (potentially for faster transmission), depending on the service requirements. This dual capability supports various mission-critical communication needs efficiently.
