I'm helping set up some systems in a large open office where there's _lots_ of RF in the area, messing up 802.11.
Running ethernet cable to each desk is pretty painful.
Way, way, back there were infrared transceivers you could hook up for data transmission. True, they were quite slow by today's standards...
Any suggestions for something avaiable today? Speed isn't too critical as these are mostly work stations with text material back and forth.
