walks a beat wirelessly and silently  Aether Systems' PocketBlue
application on a wireless personal digital assistant or notebook
PC lets law enforcement officers query databases and communicate
with each other securely and silently.  Designed for state,
local and federal law enforcement, PocketBlue can search
official records of license plates, guns, people and stolen
articles. If a query turns up a violation, the software alerts
all officers in a PocketBlue group for possible backup.  The
messages and queries are secured by 256-bit Advanced Encryption
Standard technology. Each handheld or notebook has an IP address
that can be turned off in about 30 seconds. This renders a
device ineffective if it's reported stolen.  Because only law
enforcement officials can buy PocketBlue, the GCN Lab reviewed
the software and service in a demonstration version, on both a
Palm V with a Novatel Wireless Minstrel V modem and a Research
