The original system was to have used 2.3/2.4 gHz transponders with
SpringBok software. We're talking NYCTA 'L' R143 Kawasaki trainsets.
SpringBok was dumped...7 million down the toilet. From 2.4 to inductive to now I see 900 mHz part 15 unlicensed operation. Dumb.
Oh, I filed my protests with FCC and ARRL which remain on record.
System should have gone strictly optical IR. Cheap and less interference prone than RF or inductive comm. I cannot supply the history of the project, just my interest as I was #12 on SM list.
There is also 'team ATS' of NYCTA which remains a lock-out on the internet. Too many chefs...Siemenns system in Paris worked well
since 1999 with one UNBRAKED WHEEL. CI peter
