Re: PtP vs. PtMP and max EIRP
Yeah, I've seen justification for PtP EIRP on PtMP antenna arrays.
IMO that is not allowed.
The PtP regulations in Part-15 were designed so that narrow beamwidth systems could have more power. Because they are narrow their effect is less on the area.
True, you can multiples of these systems and spread them out over degrees, but they should still be dedicated PtP.
The beam steering antennas think that every client they talk to is PtP and use the higer EIRP. Some may even be certified this way. But their use should still be PtP and I think users are instead creating a large PtMP array out of these by adding more clients per array element within the antenna.
This goes against the reasoning in Part-15 IMO.
You do this in the upper 5Ghz band and you could push a LOT of power on a "smart" sector. Which would be way above the 36dB EIRP level for traditional PtMP sectors. |
