Classic SM's associated with Advantage APs can get 14 mbps throughput but only on burst, it won't be sustained. So The Sm's will get full bandwidth for x amount of data bits....Advantage SM's get sustained thoughput and CIR configurations

Since your running advantage APs and non-advantage SM's do you still get 14mbps throughput on the AP but each subscriber can only receive 7mbps throughput. So your delivering 14mbps throughput to your group of associations? Or since your only running non-advantage sm's does the ap only deliver 7mbps throughput to the entire group?

What models? We only use 5.8GHz and when we looked at Canopy in the past they where expensive and had limited throughput. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of G.Villarini Sent: 18 January 2006 10:53 To: 'WISPA General List' Subject: RE: [WISPA] Multiple Radios on Single antenna Canopy isnt economic viable? Hmmm you can buy SM's @ $250 or less... and now the SM lite is out around $175. Its a tough call not to use Canopy. Gino A. Villarini, Aeronet Wireless Broadband Corp.

Charles, unfortunately Canopy isn't a financially viable solution at present. I have a rough idea of these 2 terms but I'll research them a little deeper to see if they shed some light. Anything else that may help on my quest? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Moldashel Sent: 18 January 2006 00:25 To: WISPA General List Subject: Re: [WISPA] Multiple Radios on Single antenna Ahhhhh......Lets do some math....... Lets say the radio has a +20 dB output. For this example there is no line loss. The antenna is rated at 30dB x-pole isolation. Here we go... +20 dB -30dB xpole = -10 dB receive level. In my book that is high enough to kill any link of the same freq on the opposite polarity....No??? Add to that a radio that needs to Rx and Tx on and off and you should have receiver blocking....... -B- Matt Liotta wrote: > Depending on various factors, you should see at least 15db of > attenuation between polarizations on a dual-pol antenna. > Theoretically, you should see 20db.
