Re: [WISPA] Ubiquiti PTMP Antenna Selection
Then again there is that part about a 120* sector and the thinking that each cpe is in fact acting like a ptp system, since the ap only talks to one cpe at a time. Just to throw another log on the fire. The 120* part comes from what I understood from someone talking about this type of discussion from the FCC. -- Original Message -- From: Matt Jenkins Reply-To: WISPA General List Date: Tue, 15 Dec 2009 12:39:24 -0800 >They are perfectly legal until you connect up that second CPE then they >are operating in a PTMP fashion and you (the operator) are violating FCC >rules. > >Gino Villarini wrote: >> Yeap! how they are selling the units as APs with the sectors ...hmmm >> >> Gino A.

Re: [WISPA] Ubiquiti PTMP Antenna Selection
My head is cloudy here.. So 5.8 CPE can be used with a 30dbi antenna? I can see that but it that true that it can be considered a ptp just because it's only talking to one far point yet the AP is ptmp? I see the logic but the FCC will go for that?

No they have not. Most likely Ubiquiti has done this to avoid having to put peak power limits on their radio hardware. 26db radio + 7 dbi omni = 33db, less than 36db allowable limit. If they included larger sector antennas to be certified with the hardware, they might get asked to hardset reduce max power of the radios, to comply with FCC EIRP limits for that specific configuration. However, if a professional installer uses a higher gain antenns, such as a 20db sector, and manually sets the transmit power of the radio down to 16db, they are still within legal Part-15 EIRP rules. We've been through this before... individually the parts are FCC certified under modular component rules (example a mpci card in a laptop) and that might be all thats necessary to allow the parts to be legally sold and distributed. The same rules that would apply to StarOS, Mikrotik, or any OEM product apply in the same way to Ubiquiti. Allthough it might be evading the issue through a loop hole, it is the only possible way to enable a single product to be interchangeable between both a PTP and PTMP use, and not have the PTP use severally compromised when used in PTP. It should be noted that in 5.8G a CPE is allowed to follow PTP rules because it is being used in a PTP way, so a 30dbi antenna is certified for use on the CPE of a PtMP system. That is my take on it.

Re: [WISPA] Ubiquiti PTMP Antenna Selection
They are perfectly legal until you connect up that second CPE then they are operating in a PTMP fashion and you (the operator) are violating FCC rules.

Re: [WISPA] Ubiquiti PTMP Antenna Selection
> Have they relaxed the rules on certification? No they have not. Most likely Ubiquiti has done this to avoid having to put peak power limits on their radio hardware. 26db radio + 7 dbi omni = 33db, less than 36db allowable limit. If they included larger sector antennas to be certified with the hardware, they might get asked to hardset reduce max power of the radios, to comply with FCC EIRP limits for that specific configuration. However, if a professional installer uses a higher gain antenns, such as a 20db sector, and manually sets the transmit power of the radio down to 16db, they are still within legal Part-15 EIRP rules. We've been through this before... individually the parts are FCC certified under modular component rules (example a mpci card in a laptop) and that might be all thats necessary to allow the parts to be legally sold and distributed. The same rules that would apply to StarOS, Mikrotik, or any OEM product apply in the same way to Ubiquiti. Allthough it might be evading the issue through a loop hole, it is the only possible way to enable a single product to be interchangeable between both a PTP and PTMP use, and not have the PTP use severally compromised when used in PTP. It should be noted that in 5.8G a CPE is allowed to follow PTP rules because it is being used in a PTP way, so a 30dbi antenna is certified for use on the CPE of a PtMP system. That is my take on it.

Re: [WISPA] Ubiquiti PTMP Antenna Selection
Is that saying any antenna with less than 30dBi gain is within the rules? Have they relaxed the rules on certification? Just curious.
