Most certainly! However the 6GHz SAS being developed is far more simple than FCC’s 3GHz CBRS SAS. The main hold up has been the FCC finalizing the AFC rules. It keeps getting pushed back. Best guess is Q1 2023 now? That being said there are multiple operators beta testing ePMP 4600 now (including myself). I know that there’s a 6GHz roadmap for PMP450m(v), but I don’t have any updates on the timeline for those radios.
Just briefly reading over the DBS-06 doc provided, it seems similar to what the FCC is working towards. You may be a bit disappointed to know that EIRP is limited to a max of 36dBm (low of 21dBm) for both AP and clients and this is contingent upon adjacent incumbent licensed users and NOT other users using the AFC database (from what I understand). This basically drastically reduces the uplink EIRP from FCC american rules that classify AP’s under PtMP EIRP rules (36dBm), and the client under PtP EIRP rules (like 51dBm IIRC?). So on the plus side… you’ll (at least initially) have nice clean 6GHz spectrum to choose from, but on the bad side, you’ll have lower total link budget then with traditional 5.8GHz devices.
WARNING! I’m not an EIRP expert, please do your own research. I’m sure someone will follow up with a “Well, technically speaking…” addendum to what I’ve said.
You are correct. I am hoping we can get authorizations for remote areas for a higher eirp, it should be pretty trivial with the system. Some of these areas would literally have nobody else using the spectrum for 100+km.
US rules for 6 GHz do not permit clients to go higher than 36 dBm. Clients and Fixed Client Devices (which use the AFC) are both limited to 36 dBm EIRP, and the AFC is not currently allowed to take antenna directionality into account. We at WISPA have asked for those changes, which the FCC resisted in the initial order, but it will require a further round of rulemaking after the band is up and running, which looks now to be maybe next summer (due to all of the AFC testing, lab and field, the FCC requires).
Canada’s rules mirror the US rules rather closely.
Thanks for the commentary Fred. We at Cambium are also lobbying and working with WInnForum and the FCC to get the rules updated to properly account for antenna directionality at a minimum, and perhaps even allowing higher EIRP for client devices (though I believe that one is a tougher sell).
Can Cambium clarify the requirements of GPS on the 6ghz clients. In the CDN docs it appears to require GPS at both the AP and SM.
If that is the case, will 6ghz SMs have built in GPS or what is the plan.
I can’t speak to the 450 SM GPS support, but I know that on the ePMP 4625 SM’s have a USB port where a GPS sync radio and puck can be added. Optional external USB GPS antenna -
GPS Puck Antenna: Part # N000940L001A
I would imagine that Cambium will do something similar for the 450 6GHz SM.
