What is Skyroute
?
SG Security Communications is pleased to provide to the security industry a new method
of communication for the transmission of event conditions. Unlike traditional methods of
communication that rely on a direct connection, such as regular phone lines, Skyroute takes
advantage of a breakthrough technology called Cellemetry Data Service. Cellemetry
enables alarm equipment to be remotely monitored in a secure, cost-effective manner by
using the existing cellular network control channels. Skyroute therefore offers improved
security, does not utilize phone lines and is not subject to sabotage or accidental phone
outages when lines are down. Combined with landline communication, Skyroute provides
dual path communication to the central station to ensure that “the alarm always gets
through” in case of emergency.
What is Cellemetry
SM
?
Cellemetry is a breakthrough technology that transmits short messages via the control
channels of the cellular network. The analog cellular network (AMPS) is divided into 790
voice channels and 42 control channels. The control channels are used to initiate cellular
telephone calls. Once the call is initiated, the cellular system directs the telephone call to
a voice channel.
The control channels are more robust than the voice channels for several reasons. First, the
control channels are digital, unlike the voice channels which are analog. This can be
compared to the superior quality of compact disc versus vinyl records. The control channels
also operate at higher transmission power than the voice channels, giving better coverage.
Finally, the cost of using the control channels is far less than the regular voice channels.
By using the cellular network, Cellemetry takes advantage of a proven technology used by
millions of cellular users and available virtually everywhere. By far, the analog cellular
network is the biggest radio network in the world and there are already 200,000,000 packets
of data transmitted over the control channels every day in North America. This represents
an average of only 10% of the maximum control channel capacity.
