Re: [WISPA] Maximum sector power?
Do not forget OOB and the likes. I have been using AirView for a while to check on my sites and some were unacceptable to me (5mhz but still hitting 10 or 20mhz at -85) so I replaced the cards (all MT sites). I am unsure if the cards are bad, going bad, or just how they were working from day one. Swapped them, and they look much better. I have been hunting down interference (most of it not self, only 2 links were over lapping and that due to the spread on the cards). I noticed that some sites had a higher then expected noise floor. I tracked it down to pretty much all of my NS5's (non M's). There is a pretty high bleed from a number of them. The linked airview screen shot shows a site with nothing but a nano5 in AP WDS mode with no clients connected. It is set for 5mhz and ch 164. The step to -...@5.810 is present with in 30 seconds of powering the nano. The next step down, to about -...@5.793 a bit after that (60~90sec). This was taken with a rocket and 120* 16db sector about 10ft in front and 10ft below the nano. The nano is running stock firmware and will be replaced with a nano5m. http://img718.imageshack.us/img718/8832/snapshot3v.png On Wed, Jun 23, 2010 at 9:12 PM, Robert West wrote: > Stick with the rules, dude.

Re: [WISPA] Maximum sector power?
We are running RocketM2's and RocketM5's and we have set policy's on the 120 sectors to limit the power on the radios to 17db they seem to act better then setting them to 20. Oddly enough much stronger signal's at 17 than at 20.. We have one site where we have the radios set to 13 and they work beautifully.

I'm just a little surprised at how easy it seems to break them, even inadvertently. The PtP/PtMP distinction does create interesting ambiguity. But then the FCC is terrible at drawing lines. Their whole approach to rulemaking is to pick out point cases and decide them, and then leave it to everyone to figure out which point case is closest to the problem at hand. I largely work in the CLEC space and the rules for intercarrier compensation are totally whacked-out. Some are from 1984, some from 1996, some from 2001, and there's newer case law all over the place, and none make any sense in the real world. So they are probably viewing PtMP as your basic home 802.11b access point, which they don't want tricked out too far, and PtP as your basic dish-to-dish microwave hop. Anything else is left to interpretation. They are apparently pretty strict about the shared bands in the 5.4 GHz range. At 5.8, it's ISM, which is basically a junque band, like 2.4, so the rules are less strict and I'm guessing there's less enforcement. But that's not a reason to design outside of the rules. >Bob- > > > >-Original Message- >From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On >Behalf Of Fred R.

[WISPA] Maximum sector power?
I'm just a little confused about some of these nice-looking access points. The UBNT Rocket M5, for instance, can put out +27 dBm. It plugs *right into* a nice 19dB sector antenna. Okay, the smaller, 120 dB sector is only 16 dB. Now math is not really my thing but I get a total ERP there of +43 to 46 dBm. FCC Rule 15.247 states that the maximum transmitted power output for digitally-modulated intentional radiators in the 5725-5850 MHz band ("ISM") is 1 watt, and the maximum antenna gain is 6 dBi. Each additional dB of antanna gain means one less dB of power. So the maximum ERP is 4 watts (+36). Point-to-point is an exception in that specific band; it is allowed unlimited antenna gain. But "point-to-multipoint systems, omnidirectional applications, and multiple co-located intentional radiators transmitting the same information" are under the cap. So am I correct in assuming that everybody who uses the Rocket M5, or any other similar PtMP system for subscriber access, turns the transmitter power REAL low (~+20 + feedline loss), in order to keep the ERP below +36? Or are we assuming that since you're technically only transmitting and receiving to one end user at a time, it's really PtP? SkyPilot's legal hack, of course, is to have eight 45 degree sector antennas and only use one at a time, so it is legally PTP even with +42 EiRP.
