If both the access point and client have 200 mW or high gain/focused antennas then range can be extended. The Emags-antenna theory of "reciprocity" applies here also. If the access point has a high-gain antenna that appears in both the transmission and reception equation, then the range can also be greatly extended. >Is LOS really needed?

It's the opposite of what you might think. Right now, the word on the street is that the 802.11a devices are not terribly useful in non-LOS applications. Virtually no Hot Spots support the a-Standard. So my guess would be that zero Starbucks support 5ghz. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Soham Shah Sent: Monday, November 10, 2003 9:34 PM To: [EMAIL PROTECTED] Subject: Re: [SOCALWUG] Range on 200mw cards So if I hook up an 8 dbi omni antenna on both location with this Senao CB3 will that do the trick?
