Re: [WISPA] 900 radio
I have a link that I tested with 2.4. I could get about a -88 signal. It might have worked. Ap is 17 dB with a 13dB 120* sector. CPE was a lucent radio with 24dB grid. That same link is now running Trango wireless. 8 dB integrated antennas and 26dB radio output. We get -75ish with the 900 mhz gear. 900 is cool stuff if there's ANYTHING in the way! laters, Marlon (509) 982-2181 Equipment sales (408) 907-6910 (Vonage)Consulting services 42846865 (icq)And I run my own wisp! 64.146.146.12 (net meeting) www.odessaoffice.com/wireless www.odessaoffice.com/marlon/cam - Original Message - From: "Matt Larsen - Lists" <[EMAIL PROTECTED]> To: "WISPA General List" Sent: Wednesday, July 12, 2006 4:56 PM Subject: Re: [WISPA] 900 radio I run every email through my BGLASS model fact checker - that takes care of the facts. :^) I haven't installed any yet.

I have also begun to use Mikrotik products (router-only, no wireless). What's with the CM9 and the RouterBoard? Is there a 900MHz solution using the RB500 series as the AP and RB112 as the client?
