Integrated 8-channel system
Works out of the box
Reliable and fully autonomous operation
The newly developed GUI based control software
Reduced the field setup time, increased the ease of operation
Suitable for operation by non-technical users
System performance based on field experiments
Average throughput with 8 channels is 18.6 Kbps, efficiency > 90%
Average round trip time using DAV modes is 1.4 sec, significantly less than 2 sec of Iridium-PSTN configuration
Average uptime with full capacity using DAV mode was 85 %; better than both non-DAV mode and PSTN mode
Percentage system uptime (at least one mode) was ~95% for all the modes
Average time interval between call drops is 60 mins and varies a lot.
In conclusion, the throughput and delay performance of the system using Iridium-Iridium DAV mode is better than other data modes.
