Re: [WISPA] 5MHz Channel Drawbacks?
I replaced mine with some Mikrotik dual band cards . They rock in the laptop, suck up on the AP. Shows me 2.4 and 5ghz. But still, I use the CDMA on the UBNT so they won't talk. - Original Message - From: "Mike" To: "'WISPA General List'" Sent: Monday, May 10, 2010 9:28 PM Subject: Re: [WISPA] 5MHz Channel Drawbacks? > Can't you just replace the laptop card with a Ubiquity card? > > One item I've built and use lately is one radio inside a rootenna, with a > power strip and another wireless router fastened to the back plate.

Re: [WISPA] 5MHz Channel Drawbacks?
I've started putting a 411 board in my AP boxes with a rubber duck antenna at 2.4ghz and a low power setting just so I can roll up and connect to the backhaul cause I'm just plain lazy. Works like a dream though. I used to use a cat5 jack on the side of the box but haven't needed it since the 411 board was stuck in there.

Re: [WISPA] 5MHz Channel Drawbacks?
Can't you just replace the laptop card with a Ubiquity card? One item I've built and use lately is one radio inside a rootenna, with a power strip and another wireless router fastened to the back plate. The main radio can be set to synch to whatever AP you want, (the ssid "any" can be convenient) and the second radio lets you connect with your laptop. I just keep that device in my Jeep. It will connect to my towers, or give me brief Internet access when I need it. I can plug in an extension cord and use it as a site survey tool, or plug the cord into an inverter in the car for the second use.

Re: [WISPA] 5MHz Channel Drawbacks?
Yeah, changed the AP to all 10MHz but still having fade outs. Spectrum analyzer shows a few consistnt holes I could drop into that should work perfectly with 5MHz. I'll try it on 2 sectors for a bit.

Re: [WISPA] 5MHz Channel Drawbacks?
Yeah, I thought about that. I've been having interference issues at 20MHz and switched to 10MHz but still having some issues off and on. I'm thinking of pulling two of the sectors down to 5MHz and try it for a week or so. Not many users on those 2 so we should be okay on the throughput. It's a rural area, shouldn't realy have much RF but it's there.

I'm not sure about all U-NII bands in the US, but in some countries one might exceed power spectral density limitations(dBm/MHz) using narrow channels.
