Group Call and All Call are two common calling methods in wireless communication, which are widely used in walkie talkies and other two-way radio devices. The following are their main differences:
Group Call:
Definition: Group call refers to a call initiated by a user in a specific communication group or channel that can be received by all members of that group.
Purpose: Group calling is usually used in situations where communication with specific groups or team members is required, such as work teams, emergency response teams, or other fixed groups.
Feature: Group calls are only for preset groups, and not all users on the channel can receive calls. This approach helps to reduce unnecessary communication interference and improve communication efficiency for specific groups.
Operation: Users initiate group calls by selecting the corresponding group channel or entering specific numerical codes.
All Call:
Definition: Full call refers to a call initiated by a user in a wireless communication system that can be received by all users in the system, regardless of which channel or group they are in.
Purpose: Full call is usually used in emergency situations or situations that require widespread notification to all users, such as issuing important announcements, emergency evacuation instructions, or searching for specific personnel.
Feature: Full call covers the entire communication system’s users and is not limited by channels or groups. This approach ensures that information can be quickly conveyed to all possible recipients.
Operation: The user initiates a full call through a specific full call channel or function key. In some systems, additional permissions or passwords may be required to use the full call function.
In summary, group calling is a communication method aimed at specific groups, while full calling is a broadcast communication method aimed at all users in the entire communication system. Both have their own applicability and importance in different scenarios and needs.
