all- just to follow up on this before i forget about it. the slides from andy warner's presentation at the last wireless users meeting are available for your perusal[1]. i haven't seen anything regarding this on the lists so i figured i would get the content online. for those of you that missed it, andy gave a really nice presentation regarding RF technology as it applies to wireless networking. the slides are well worth the review. references ---------- http://www.tc-unwired.net/misc-docs/rf_primer.pdf -- steve ulrich sulrich at botwerks.org PGP: 8D0B 0EE9 E700 A6CF ABA7 AE5F 4FD4 07C9 133B FAFC
