3004B-MI Neon Remote Logger Iridium Short Burst Data
The 3004MI Neon Remote Logger Iridium
SBD is a Neon Remote Logger in the
3004M range which has a smaller form
factor than the standard metal enclosure
3004. It is housed in a polycarbonate case
and utilises the high reliability Iridium
satellite network short burst data
subsystem. It is a high reliability message
based system, providing reasonable cost
satellite communications and a low latency.
This service is ideal if you have a requirement for short messages to report sensor data. Latency
from such systems is in the order of minutes and the satellite airtime costs reflect this low latency
service.
