YMMV, of course: Realistic throughput on a 802.11g is usually a lot less than the theoretical one. Like half. And it depends on distance, antenna configuration, intervening structures, interference, the phase of the moon, etc. The encryption takes up a very small amount of actual bytes transmitted, but it does require calculation (CPU) overhead on both ends to en- and de-crypt. Of course, the cost of getting your information intercepted unencrypted might be a lot higher ;) And you are planning on using WPA2, not the old WPA, right? Newer encryption schemes keep everyone from cracking your transmissions in seconds. It's worth reviewing the current state of the art (start at http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access) before you roll out something that's more window dressing than real protection. -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
