Multiple Talk Group Types Customized to Meet Customer Needs

Personal Groups are created by a user and are only visible from the creator’s Group List. Only the creator may initiate a call to a Personal Group.

Member Groups (Group Size Limit is 250):
Member Groups are visible in all member’s Group Lists. Any member of the group may initiate a call to the group.

Enterprise Open Groups (Group Size Limit is 250):

Law Enforcement Surveillance Channel (Group Size Limit is 250):
Surveillance Channel Groups were created for use by Law Enforcement personnel whose typical profile requires long calls, that cannot be automatically ended after brief periods of inactivity.

Public Safety Unicast Channel (Group Size Limit is 250):
Unicast Channels provide a means for Public Safety agencies to broadcast important audio feeds, such as NOAA Weather, Air Traffic Control, and any LMR network in a “monitor only” mode.

Enterprise Dispatch Groups (Group Size Limit is 250):
Enterprise Dispatch Groups have definable time of day/day of week shifts associated with them. The members of the group can change for each shift. Also, the owner/manager of the Group may or may not be a participant in the Group and there may be more than one Group Manager. Users with a Dispatch Group in their Group List need only to call the group and it will be routed to those members of the group that are on shift at the time.

Broadcast Groups (Group Size Limit is 60,000):
Broadcast Groups are used to deliver high priority messages. Broadcast Group calls are high priority unicast voice messages. Broadcast messages will re-try until all messages have been delivered.

Adhoc Groups (Group Size Limit is 250):
Adhoc Groups are not pre-configured groups, but rather a selection of multiple Contacts from the Contact List. Once the Contacts are highlighted, the user presses the PTT button to establish a call.
