Re: [nycwireless] Wireless Census THIS WEEKEND
Awesome! I won't be around, but please take photos, and keep documentation! This is huge! Also, do you know how you're going to gather people's data?

Re: [nycwireless] Kit followup: which setup?

[nycwireless] Kit followup: which setup?
Hi: I'm trying to settle on hardware for the upcoming wireless census and I have a question about wireless receivers. We want something that'll work on the greatest range of laptops and OS'es (MAC, PC, Linux), so we're standardizing on USB connections (not serial or PCMCIA) and devices that'll work on all platforms. I'm trying to decide between the Orinoco USB (~100mw) and the Senao USB (200mw): http://cgi.ebay.com/Orinoco-Gold-USB-powered-Wardriving-w-RP-SMA-NEW_W0QQitemZ120016738108QQihZ002QQcategoryZ61816QQssPageNameZWDVWQQrdZ1QQcmdZViewItem http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=34250675&category=45002#ebayphotohosting My question: for optimal reception, is it better to have a highpowered card with a basic antenna (senao) or a lower powered card with an excellent antenna (orinoco)?
