Telling the packet to go out an ap connected to a 7* (up to 9* depending on location in the array) does NOT move the beam patern of the antenna.
All that seems to be happening is hooking a slug of ap's to a group of properly arrayed antennas and making sure that no packets are transmitted via an ap that they are not supposed to go to. No wasted power? Um, what, exactly, do you think that all that extra power that blows through buildings is gonna do to the ap's that are mounted outdoors??? Including other Vivato ap's. And I've not yet heard from anyone that's tried to use one of the vivato demo systems (including me) and gotten anywhere near the range that's been advertized. This could work, I'm not saying it won't/doesn't. I'm supposed to get my hands on some gear to test. If it lives up to the hype it'll be a great thing for high density areas. I just can't get the visions of .com boom baffel them with bs if you can't dazzle them with brilliance business plan out of my head........ I'm no phD but what I've seen of how high powered systems work in most cases has not been good. We all know of someone that put 1 watt amps on high gain antennas and then complained about poor range etc. Drop back down to a low (normal) output and all starts working fine. As a farmer it PAINS me to say this but: A bigger hammer is NOT always the best way to get something done. marlon ----- Original Message ----- From: "Oliver Shaw" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, May 30, 2003 11:55 PM Subject: Re: [smartBridges] bandstearing? > > Yes, vivato does steer the beam as well.
