| 244483 | 2004-06-14 22:05:00 | Hi there, I'm about to get an USB IrDA 1.1 receiver, but was hoping someone could explain to me the difference between this and a 1.3 version. I assume it's simply speed or something. The IrDA 1.1 claims it is compatible with "FIR 4 Mbps, MIR, SIR and ASK 56 Kbps" while the 1.3 claims "IR data rates from 2.4K to 115.2Kbps (SIR Mode), 576K to 1.152Mbps (MIR MOde) & 4Mbps (FIR Mode)". To me they seem to be the same.... Any help would be much appreciated, Cheers, Jonathan. |

They both seem to handle up to the 4Mbps speed. I can't see any obvious difference without going to the www.irda.org and looking at the standards. ("irda 1.1"and "irda 1.3" to Google will get you started). I've found irDA an "interesting" experience. @#$$%%^#$@ :_| It seems to be OK if you are using only one external device. If you use a PalmPilot, and get lucky with a connection, you would be extermely fortunate to use a Pocket PC immediately afterwards. ;-) |

| 244485 | 2004-06-15 02:46:00 | Cheers Graham. I'm soon to be getting a Nokia phone which has IR capabilities. Do you think I keep with my IrDA 1.1 or chuck in the extra money for 1.3? I haven't yet purchased the 1.1. But I doubt the Nokia is hardly picky about which it prefers. I'm interested in hearing more about your experiences with IrDA - I'm a complete newcomer to it. Cheers, Jonathan. |
