What Can You Do with 45 MHz of Additional Spectrum?

Commissioner Pai suggests only 45 MHz of the 75 MHz total be dedicated to Wi-Fi. While it’s as yet uncertain exactly which rules this added spectrum would follow, he did state it would be contiguous to the existing 5.8 GHz spectrum, meaning 5850 to 5895 MHz. If the FCC decides to follow the same rules as the existing 5.8 GHz band, this would be very advantageous for fixed wireless deployments.

For existing Cambium Networks customers using either ePMP or PMP 450, this is very welcome news. These products were already designed to support frequencies higher for regulatory regions outside the United States. Therefore, they support these frequencies with optimal performance, and will only require a software update in order to take advantage of these frequencies, which are not currently being used by anyone.

A LOT.

I have read about Wi-Fi 6 (or Wi-Fi 6E) an increasement of the bandwith to "free" part of the the 6 GHz.

If is true, our devices support that kind of frequence?

"In 2020, we will finally get it: A big chunk of new wireless spectrum in the 6 Gigahertz (GHz) band – potentially from 5.925 GHz up to 7.125 GHz."

https://www.testandmeasurementtips.com/what-you-should-know-about-wi-fi-6-and-the-6-ghz-band/

The 6-GHz frequency band, also called mid-band spectrum, spans 5.925 GHz to 7.125 GHz. It is divided into four bands:

UNII-5: 5925-6425 MHz (500 MHz)
UNII-6: 6425-6525 MHz (100 MHz)
UNII-7: 6525-6875 MHz (350 MHz)
UNII-8: 6875-7125 MHz (250 MHz)

As mentioned in the OP... the band "would be contiguous to the existing 5.8 GHz spectrum, meaning 5850 to 5895 MHz"... so it wouldn't actually be hitting 6ghz.

PMP450i's radio is capable of tuning between 4900 - 5925 MHz

PMP450's radio is capable of tuning between 5400 - 6000 MHz

e3k's radio is capable of tuning between 4910 – 5980 MHz

e2k's radio is capable of tuning between 5150 - 5970 MHz

e1k's radio is capable of tuning between 4910 – 5970 MHz

If the FCC allow use of this new band with little change to the rules or mechanisims to access it, it's highely likely that all of Cambium's existing 5GHz radios could be certified for use of this new band. If the FCC decides to make access to the band more complex, like it did with 3GHz and CBRS, by requiring a SAS, this might make it more difficult and expensive to utilize.

The article's author, Matt Mangriotis w/Cambium states:

"For existing Cambium Networks customers using either ePMP or PMP 450, this is very welcome news.

I continue to be optimistic that the FCC will act on this in the near future. It's a very good thing for WISPs using Cambium equipment in the US.

Telemar - When you refer to Wi-Fi 6, this is the chipset capability, not necessarily the regulatory environment. For example, in the US, opening 6 GHz has been talked about, but there will be vary large hurdles to doing so... even opening this additional 45 MHz has caused a stir among amateur radio operators (HAM radio folks), but this may be a bit misguided or confused.

It seems like a lot has happened since January 2020. Is there somewhere on the Cambium web site that describes the vision for 6 GHz? I’m particularly interested in the PMP-450 and I’m Canadian so I would welcome any thoughts on the opportunites and challenges around the ISED decision as well as the FCC decision.

Thanks

Not exactly what you are looking for, but there is a bit more discussion of 6GHz here:

Thanks for the reply. I also see that 6 GHz shows up in the Animal Farm presentation as part of the 450 “plan of intent” in 2nd half of 2022.

that would make the upper 5Ghz band usable for an 80Mhz ptp link and still not hose the rest for an AP or two! Hell, 40Mhz of clean spectrum means no more getting stepped on by other systems (5Ghz boosters! yuk!)
