Just needs bigger antenna, Fred. However, I'll be damned if I can find antenna with what I'd consider appropriate gain. I deploy 5 Ghz systems with 18 - 20 dB at the AP and 25 dB at the CPE. UBNT 900 has an AP of 13 and a CPE of 11. That's 15+ dB of less margin than I'd deploy elsewhere. How well of a 900 MHz system could you run with an additional 15 dB of gain? Not only is your signal a lot hotter, but you're also hearing less noise.
Sure, those antenna would be large. However, if it's worth doing, it's worth doing right. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: "Fred Goldstein" <[email protected]> To: [email protected] Sent: Thursday, August 22, 2013 9:36:48 AM Subject: Re: [WISPA] Latest trend for heavy wooded areas On 8/22/2013 10:14 AM, Mike Hammett wrote: Almost every time someone has detailed their installations to me, there just isn't enough signal to do anything. They're getting a -76 and wondering why it doesn't work. Increase that another 15 dB and try again. The Canopy will work a little better because it requires less signal, but it also has nowhere near the same throughput, so they're really apples and oranges. The spec sheet makes it sound as if -76 is more than adequate, and in a PmP environment, it's often hard to get a stronger signal. Are the poor results from trying to run at too high a rate, like MCS5, such that running at say MCS1 would improve results? Or is it just not very sensitive, with a higher noise temp than Cambium? -- Fred R.
