• Signaling System 7 (SS7) network, which authenticates devices and transports

IS-41 signals – including the MicroBurst™ data packets – between Aeris.net’s

central hub facility and the cellular carrier switches.

• Internet and dedicated TCP/IP data links provide transport for the data traffic

between the Aeris.net hub and application host facilities, from which the

endpoint devices are remotely monitored and controlled

• Aeris.net central hub facility, which provides the central processing functions

for the MicroBurst™ service

• MicroBurst™ devices, which are application-specific, programmable

telemetry units that consist of a cellular transceiver (referred to as the

MicroBurst™ RF Module); a micro-controller with memory; MicroBurst-

specific firmware; a CMOS serial connection between the Module and micro-

controller; and sensors, as appropriate

MicroBurst™ service uses standard cellular control channels to transmit and receive

data to and from MicroBurst™ devices. There are two types of control channels:

Forward Control Channels (FOCC), which operate from the cellular switch out to the

MicroBurst™ device, and the Reverse Control Channels (RECC), which operate from

the MicroBurst™ device back to the switch.
