THE MODERN MOBILE RETHINK HOW MOBILE AMATEUR RADIOS CONNECT TO MODERN
ELECTRONICS LADEN VEHICLES.  ALAN APPLEGATE, K0BG  MODERN VEHICLES ARE
ROLLING COMPUTERS, WITH SOME MODELS HAVING MORE THAN 100 CPUS CONTROLLING
EVERY CONCEIVABLE FACET OF VEHICLE OPERATION.  THE ENGINE CONTROL COMPUTER,
COLLISION AVOIDANCE SYSTEM, THE STABILITY AND TRACTION CONTROL SYSTEM, THE
NAVIGATION SYSTEM, HEATING AND AIR CONDITIONING, AND ABS AUTOMATIC BRAKING
SYSTEM ALL CONTAIN CPU BASED CONTROLLERS.  FURTHERMORE, EACH AND EVERY ONE
HAS A SET OF SENSORS FEEDING THEM INPUT DATA, MUCH LIKE A KEYBOARD ON A PC.
BY NECESSITY, ALL OF THESE CPUS ARE TIED TOGETHER VIA MULTIPLE DATA BUS
SYSTEMS LANS LOCAL AREA NETWORKS IN OTHER WORDS.  GOOD EXAMPLES ARE THE
WHEEL SPEED SENSORS.  THEY FEED DATA OVER A LAN TO BOTH THE VEHICLE
STABILITY SYSTEM AND THE ABS, BECAUSE THESE SYSTEMS MUST INTERACT.  BESIDES
THE LANS, WANS WIDE AREA NETWORKS ARE BECOMING COMMON.  THE BEST EXAMPLES
ARE GMS ONSTAR AND FORDS SYNC.  THEYRE THE MOBILE EQUIVALENT TO A HOME WI
FI, AND ARE COLLECTIVELY REFERRED TO AS TELEMETRICS.  WHILE NOT WIDELY
IMPLEMENTED, THESE WANS ARE ALSO CAPABLE OF TRANSMITTING OPERATING DATA TO
A REMOTE SITE.  FUTURISTICALLY SPEAKING, THEY COULD TELL A LOCAL LAW
ENFORCEMENT OFFICER THAT YOURE SPEEDING.  ASIDE FROM THE BIG BROTHER ASPECT
OF MOBILE COMPUTERIZATION, THIS COMPLICATES THE INSTALLATION OF AMATEUR
