New IrDA Spec Shoots for 100Mbit/s Data Rate 111
An anonymous reader writes "According to an article at DeviceForge, the Infrared Data Association has adopted a new high speed IR communications protocol. This new protocol promises to deliver possible speed up to 100Mbit/s transfer rates. From the article: 'Of note, existing IrDA-enabled devices can be upgraded to the new protocol, thus offering the opportunity to accelerate the IrDA data transfer rates of devices in the field via a software update.'"

bluetooth is more convenient since irda requires line of sight
well, we always talk about a trade off between convenience and security, and there is the tradeoff right there
so i think broadband irda has a blockbuster future
because security concerns are nothing to sniff at in a marketplace full of it departments spooked by security scares

That is a gross over-simplification. IR doesn't "just work", except perhaps in Windows XP. Even if you do get it going, it's still limited to modem-like speeds. Getting "Fast IR" (4meg) working is a joke; I once worked in a laptop factory and had to monitor the IRDA testing setup down on the production lines. In controlled-conditions, with single-tasking custom testing software, we still had problems getting reliable communication from otherwise perfect built products. I investigated things like distance, ambient light etc in order to bring down the high erronous failure rate. In the end I think 7 inches was the opimum distance for Fast IR.
So, this is me, in a lab with two laptops (one known-good) hooked up on a specially designed test harness. And it still is unreliable! Good luck getting it to work reliably on the street!
Granted, newer OS's make this all easier and it runs "out-of-the-box", but IRDA has thoroughly earned it's "piece of shit" ranking in my mind. Maybe I'm just bitter at it's complete imcompatibility with "consumer IR" protocols; if it could interface with TV's etc and input stimulus from other remotes, it might have had a use over the years. This simple functionality was omitted for some reason or other. Now, BT and WiFi kick it's butt up and down the ball-park in the things that matter; speed and reliability. IR will have to nail both of these to stand a chance however I don't think your "fire and forget" use will be popular enough to make it mainstreem.
