Database Size Calculator Notice
"DB Growth per Month" calculations are based on Motorola's "Voice and Data Traffic Profile" from System Planner with the following parameters:
• High GPS: 60 sec GPS interval per user per 1 hour.
• High Voice: 3 Calls per user per 1 hour.
We recommend doubling the calculated size as a precaution.
Precise calculations can be made after monitoring the radio system for a month and analyzing transmission times and GPS traffic.
