Critical Systems & ISM (was RE: [MLB-WIRELESS] Wireless 'cloud' may offer silver lining Or is it just 'pie-in-the-sky' technology?)

Actually the wireless interface has nothing to do with synchronization, but
allows trams & emergency vehicles to control the lights. I guess some upper

NOW THAT IS A SYSTEM WORTH CRACKING  :)

I've always wondered about them too; I know there's a system that allows the
PM's car to make the lights go green in city intersections, I've always
presumed these aerials were it..... know all we need to know is what
frequency they use and what the code is :-)
