Each Sensor Pack is activated
with a one time fee of $30 and data communication service is billed
monthly according to actual message delivery.
The system ensures maximum transmission
reliability by retransmitting redundant messages which are automatically
filtered and are not charged on your monthly bill. Low per message
pricing (pennies) per alarm message. Daily status messaging free.
Sensor Packs transmit only when triggered. Code Phase Division
Multiple Access (CPDMA™) technology allows the ground station
decoders to separate overlapping transmissions.
