1. RE: [Karlnet] Bandpass filters (score: 1): Author: "Travis Brown" <travis@netwaveva.com>; Date: Mon, 1 Jul 2002 09:52:43 -0400; Tony, Thanks for the reply. So, this may not help me... Hmmm... What's the real use of the filter, then. What good does it do to isolate my frequency? I knew it wouldn't help with noise right on my c; /archives//html/Karlnet/2002-07/msg00001.html (8,832 bytes)

RE: [Karlnet] Bandpass filters (score: 1): Author: "Tony " <tonylist@wwwbiz.com>; Date: Tue, 2 Jul 2002 02:06:57 -0400; Travis Ah this is a good point if you can find notch filters for each channel, 22Mhz wide each this would help to isolate antennas that are close to each other in side the 2.4Ghz band.

[Karlnet] Bandpass filters (score: 1): Author: "Travis Brown" <travis@netwaveva.com>; Date: Thu, 27 Jun 2002 09:40:51 -0400; Anyone using bandpass filters on your base gear due to dirty tower sites and such? We have a base (AP-1000) that shows very high noise at the tower site, and I'm hoping a very narrow bandpass filter; /archives//html/Karlnet/2002-06/msg00282.html (8,675 bytes)

RE: [Karlnet] Bandpass filters (score: 1): Author: "Charles Chia Sheng Wu" <cwu@cwlab.net>; Date: Thu, 27 Jun 2002 13:34:08 -0500; it all depends on notch size - there's a company in Ohio that makes a nice amp w/ a 22 MHz notch - think they're called Rflinx or something -Charles --Original Message-- From: karlnet-admin@WISPNotes; /archives//html/Karlnet/2002-06/msg00285.html (9,650 bytes)

6. RE: [Karlnet] Bandpass filters (score: 1): Author: "Travis Brown" <travis@netwaveva.com>; Date: Thu, 27 Jun 2002 15:09:49 -0400; Mel, One typical customer off this base as a s/n of -64dbm/-79dbm. On our "quiet" bases, we see customers at similar distances and CPE setups having something like -58dbm/-95dbm. Clean, quiet, and FA; /archives//html/Karlnet/2002-06/msg00287.html (13,012 bytes)

Etheridge" <mele@enia.net>; Date: Thu, 27 Jun 2002 16:40:36 -0400; So could you use this to filter all but just one freq set in the 2.4 ISM band? Say channel 1 or 6 or 11?

8. RE: [Karlnet] Bandpass filters (score: 1): Author: "Travis Brown" <travis@netwaveva.com>; Date: Thu, 27 Jun 2002 16:54:48 -0400; Yes. The filter can be set to, for instance, 2.427GHz (channel 4) with a 22 MHz bandwidth (+/- 11 MHz from the center frequency), which is the optimum bandwidth for an 802.11b channel.

RE: [Karlnet] Bandpass filters (score: 1): Author: "Tony " <tonylist@wwwbiz.com>; Date: Fri, 28 Jun 2002 21:03:06 -0400; Travis For the most part bandpass filters will not help if the interface is within the 2.4Ghz band (IE the channel you are on). It will just "Notch" out the frequencies you are working with. It does; /archives//html/Karlnet/2002-06/msg00291.html (8,628 bytes)
