Trailer Tracking Unit (STT) uses Aeris.net as its data transmission network.
The Aeris network can be described as an umbrella network for local
and regional analog cell phone networks. It provides one of teh largest
coverage areas available. Users of this network typically only need to
locate their trailers a few times per day, once a week or only when the
trailer and its cargo have been stolen.
Aeris has formal agreements
with cellular carriers throughout North America to support the deployment
of MicroBurst® technology, enabling the wireless transmission of
data. This network covers
over 98 percent of the U.S. population and 100 percent of the populations
of Canada and Mexico. The MicroBurst technology operates completely within
current established cellular networks, piggybacking on unused channels.
