How is IEEE 802.11 bb different from IrDA ?...

[amal banerjee]

Very recently, IEEE released the standards for the IEEE 802.11bb, for
line-of-sight, secure communications between devices at near infrared.
How is this different from IrDA, the standards for which were released
around 1993. I did some investigation, but could not get anything concrete
about it.

IrDA is slow (comparatively speaking).
802.11bb is intended to be *really* fast.

IrDA was, essentially, a (cheap!) wireless means of communicating
with small \"peripherals\" -- like printing from your PDA.

802.11bb is intended to be a first-class communication protocol on a peer
with other networking technologies (albeit point-to-point).

Think: serial port

Think: NIC

Yeah, that\'s how it was used, but... I was always bummed that engine computers
used a special electrical connector, hidden somewhere inside the engine compartment,
when they could just as easily have been implemented in IRDA on the instrument panel, or
next to the vehicle number behind the windshield.

I suspect that would require more standardization and some sort of \"bridge\"
e.g., to allow CAN access.

It\'s actually amazing that so many things are standardized when you
think of the competing influences at play!

the OBD connector must be somewhere within reach when sitting in the drivers seat
