Sierra Wireless Modems has been awarded a contract by Pro Tech to track offenders using GPS satellites and real-time wireless data.

Pro Tech will use wireless modules to transmit information in monitoring the location of offenders under community supervision such as probation and parole.

Sierra was selected by Pro Tech Monitoring as part of their patented "offender satellite surveillance system". The SB 220 OEM module is located in the portable tracking device (PTD) that transmits wireless data back to the Surveillance Data Centre.

"Our business aims at taking offender monitoring into the 21st

century and Sierra Wireless was a clear choice of partner in our

integrated, breakthrough wireless solution," said Bob Martinez, PTM,

President and former Governor of Florida.

"This contract highlights Sierra continued strategy to deliver

practical, effective wireless solutions to new segments of the public

safety market," said Jason Cohenour, Sierra Wireless Vice President

of Sales. "The SB 220 allows us to deliver a compact, feature rich

product in the smallest form factor."

"The SB220's flexible form factor and easy configuration made it

the perfect option for our complete wireless solution," said Hoyt M.

Layson Jr., Vice President, PTM and Inventor of SMART.

How the Wireless Solution Works

The offender is fitted with an ankle bracelet and given a PTD

that monitors the proximity of the ankle bracelet. Global

Positioning System (GPS) satellites track the PTD's location 24 hours

a day. Corrections personnel can declare any area off-limits and

establish a daily schedule for the offender. Off limit areas and

daily schedules are programmed to the offender's PTD using cellular

communications. If the "hot zone" is violated, the offender is

notified of the violation and a wireless message also advises the

supervision agency of the violation.

Victims at risk also receive advance warning that the offender is

in the hot zone, giving the victim the necessary time to move away

from the offender. Victim notification can occur via fax, pager or

cellular telephone.

The wireless data is currently transmitted via circuit-switched

cellular (CSC), which is based on the amps networks used on today's

cellular phones. Future implementation of Cellular Digital Packet

Data (CDPD) network is planned.

The SB220 OEM Module

The SB220 represents the smallest form factor with multi-mode

access capability. Chosen by leading developers of mobile computing

solutions, the module equips your system with dual wireless data

modes (CDPD or CSC) and wireline and fax as standard.
