SWIFT "Store and Forward" - Full Swift report (up to 60 coordinates per report, without additional parameters) takes 2 seconds of transmission per Subscriber on Time-slot.
Report with 30 or less coordinates without additional parameters, takes 1 second of transmission per Subscriber on Time-slot.
With report every 120 seconds - 120 radios can send full report (up to 60 coordinates in report) utilizing Time-slot per minute.
With report every 120 seconds - 240 radios can send half report (up to 30 coordinates in report) utilizing Time-slot per minute.
More information on "Store and Forward" feature can be found on our site.

Note!
Default parameter 120 seconds for report send is based on the average optimal ratio, which in it's turn is based on the empirical experience of using the solution.


Regular GPS – Takes 1 second of transmission per Subscriber on Time-slot.
With report every 30 seconds - 60 radios can send report utilizing Time-slot per minute.

Enhanced GPS (windows 5-10) - Supports for up to 360 location responses per minute per repeater using both slots, while running at 90% capacity, hence takes 1/3 of second of transmission per  Subscriber on Time-slot
With report every 30 seconds - 180 radios can send report utilizing Time-slot per minute.

Enhanced GPS (window 1) - Supports up to 1808 location responses per minute per repeater using both slots, while running at 90% capacity, hence takes 1/15 of second of transmission per Subscriber on Time-slot
With report every 30 seconds - 900 radios can send report utilizing Time-slot per minute.

Enhanced GPS (window 2) - Supports up to 896 location responses per minute per repeater using both slots, while running at 90% capacity, hence takes 1/7,5 of second of transmission per Subscriber on Time-slot.
With report every 30 seconds - 450 radios can send report utilizing Time-slot per minute.

Note!
TRBOnet console has built-in Enhanced GPS calculator available in GPS trigger settings when Scheduled GPS type is selected.
