There exist 4 classes of IRDA intended for short range. (1m) The speed or distance is limited due to the power received in 1 bit by the photo receiver.
The limits apply to standards, but you can always go slower.
SIR = 115kbps
MIR = 1.152 Mbps
FIR = 4Mbps
VFIR = 16Mbps
enhanced distance to a few m may be possible with VFIR 2Mbps using carrier modulation of ?8MHz carrier.
These must be treated as Class 1 lasers and the optical epoxy melts easier than most IC's so you must learn how to hand solder in < 2sec with flux and expert technique.
