Bill Trost once stated: =Slotted ALOHA is probably overkill for this task. You probably do not =want to try more than two nodes in the infrared network. The reason =is that IRdA ports have a fairly narrow beam width (30 degrees, as =I recall), and not that great a range (3 feet +/- 3 feet). As soon =as you add a third node, you will probably start running into hidden =transmitter problems. ALOHA would deal with that in the simple case, =but you more or less have to "know" that one node can reach all the =other nodes in the network. What if some new "hot/cool" laptop will come with IR port capable of talking to more then one other? Should FreeBSD be limited "in advance"? -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
