Characteristics of Physical IrDA Data Signaling
Range: Continuous operation from contact to at least 1 meter (typically 2 meters can be reached).
Bi-directional communication is the basis of all specifications.
Data transmission from 9600 b/s with primary speed/cost steps of 115 kb/s and maximum speed up to 4 Mb/s.
Data packets are protected using a CRC (CRC-16 for speeds up to 1.152Mb/s and CRC-32 at 4 Mb/s)
