Any chance of 6GHz PMP450?

(Continuing the discussion from Could a 450M 3GHz support 3900 - 3980MHz?)

Additional to my question above about whether Cambium would consider a hardware revision for 3900-3980, I’m curious about Cambium’s ability to operate in the 6Ghz Band with the 5Ghz 450m(or an alternative) for Point to Multipoint purposes.

For background:
ISED Consultation

Item 93 in the 3800 consultation;
“In addition, ISED had been monitoring the U.S. process for the 5925-7125 MHz (6 GHz) band. In the Spectrum Outlook, ISED classified this band as a Priority 3 with a plan to monitor international activities, given that discussions in the U.S. had just begun at the time of its publication. However, ISED now considers the 6 GHz band as Priority 1 based on the developments taking place internationally, and will be developing a consultation on making this spectrum available in Canada.”

So naturally, I was curious if Cambium has a radio available that could utilize that spectrum? My guess would be the 5Ghz 450m. The spec sheet says up to 5925, but I’m sure it can go higher with software… but high enough is the question.
@CambiumMatt, are you able to comment on that? Any insight would be helpful for us Canadian’s in limbo right now, wondering about what our future spectrum might look like… and just what the heck we can do with it?

Thanks for the questions Neil…

With respect to 3 GHz, as noted above, there needs to be new hardware to support anything above 3.900 GHz. We are not yet working on anything, but there is potential for this in the future.

With respect to 6 GHz (5.925-7.125 GHz), we are working toward a new product (new hardware) that is capable of supporting this. The ePMP series product is based on 802.11 chipsets, and the 802.11ax chipset (also known as WiFi6e) will be capable of this band per the standard.

For 450, this is new development, but between the US market and other markets opening up globally, we believe we will be pursuing a new 450-based product for the 6 GHz band as well. We are really excited about this, as this will certainly be a big leap for the platform in both new spectrum and radio performance.

The current hardware will only support up to 5.925 GHz.


For a bit of additional color, the US market for 6 GHz will require AFQ (Automated Frequency Coordination) to protect encumbents (license holders). This makes things a bit more complex, and we estimate the band to be ready toward the end of next year (2021), or early in 2022.

This is around the same timeline we expect to have both ePMP 4000 and the “next gen” 450 available.


As a follow-up @CambiumMatt, ISED has posted a consultaion on the 6Ghz Band. Perhaps you are already aware of this, but if not I suppose it would be of Cambium’s interest.

Yes, I have seen that last week, and we are running that down to understand the differences between this and what the FCC is proposing… at first glance, they are quite similar.

More information from ISED…
The 6 GHz decision has been released. There is an Automated Frequency Coordination (AFC) ocmponent but the relevant standards and procedures still need to be developed. The ISED Decision indicates that they will adopt an AFC that is “harmonized with the U.S. to the maximum extent possible”
