3.65Ghz FCC certification

Is there any way to get a MikroTik RB333 with a Ubiquiti XR3 card FCC certified to operate in the 3.65-3.70Ghz range?

They are great to work with. Very professional.

The last Mikrotik stuff we got certified is certified for 3 components:
1.antenna
2.Radio Card
3.Pigtail

It’s not as expensive as everyone thinks.

Justin,

If you believe everyone thinks incorrectly why not just tell us how much it was instead of making everyone ask the people in the link you gave which will cause them to raise the price because everyone bugs them?

Please just provide an approx amount…

Also, exact what did you get certified? Hit me directly if you want but I am very interested in knowing this. scott)*at(*brevardwireless.com

I just spoke with Jon Hartman from Agile Test Group, he is getting a quote put together for FCC certification of the XR3 on a RB333. He says it will definitely be under $10k but until he checks on a few things, can’t give a better price estimate.

btw Justin, What company did you get things certified under? He said they had no record of ever certifying anything MikroTik. I had him check to see if it would reduce the amount of testing required for us, but he turned up nothing.

I think if you added some standard stuff a large group of us could agree on we could go in together and have it be affordable and certified. Its a win-win for everyone involved. Now is the time to get some more peoples attention. Imagine price at 100 companies involved for several sets of normalized gear (AP / Client / Backhaul etc…)

I was thinking the same exact thing… I can’t justify more then a few hundred dollars to get the gear certified, but if we get 35 people (or less depending on the pricing estimate I hear back) that all chip in $300 to do so, we can all easily accomplish this.

the specs I was planning were as follows
RB333 (or maybe the RB600?)
ROS v3.x
Ubiquiti XR3

certified for standard contention protocol (i.e. not disableing CSMA) which allows for use in full 50mhz of the 3.65-3.70Ghz range

I’m hopeing that he tells me it can be used with any antenna less then nn dBi but if it has to be tied to a particular antenna as well, something in the 25-29dBi range (suggestions?)

7

I too would be willing to chip in to help get things going. I wander how many other configurations have already been certified.

8

Can this be applied to other frequencies as well? If we can get a handful of systems certified, I’m in. If its $10k per config, I’m not certain I’ll be using 3.65 anyway, so I wouldn’t really benefit.

Got some more information from Jon…

  1. confirmed that the antenna thankfully does not need to be part of the system certified so once we have a certified system, each user is free to pick the antenna most appropriate for their needs, as long as it does not violate the FCC power density limits of 1 watt per MHz of channel width for this band.

  2. Since UBNT is nearly complete getting a modular certification for the XR3, we only need to get the unit part 15 certified, which is closer to $3k estimate (official quote coming later today)

Can this be applied to other frequencies as well?

no, the certification is specific to the radio / board combination used, therefore the certificate will be for 3.65-3.70GHz only

10

none that I am aware of, I had them do some quick searching and he didn’t find anything related to MikroTik for any licensed bands, but it was not a comprehensive search and could have easily have missed something.

Official quote came back:

Reference: United States
Test Name: FCC Part 15, Subpart B – Unintentional Radiators
Price (US): $2,000.00

Tests performed:

15.107 Conducted Emissions
15.109 Radiated Emissions
Test Report

>
> This quote assumes that the Ubiquity module has prior approval from the FCC

They will not be able to perform the test until Ubiquiti gets their certification, which according to Robert from UBNT, is expected by the end of Feburary. Once that has taken place, they will be able to start the testing, and will take up to 30 days before we get the results (usually sooner)

We need 7-10 people (or more) to get together who are willing to pay between $200 and $300 to get a XR3 system part 15 certified so that we can register them as base stations for 3.65GHz.

Don’t you mean Part 90? Part 90 is for 3.65 and Part 15 is for the lower range.

according to the FCC certification company, we only need the Part 15, Subpart B, Ubiquiti is getting the Part 90 Modular certification, which means the only thing that needs to get certified is the assembled unit for a Part 15 (once ubnt received their certification.)

14

The way I understood it was:

The XR3 has to be certified with Part 15 and Part 90. Once that is done all we need to do is register to fcc with 3.65 license if you want it. Otherwise the part 15 frequency (public) you dont need to do anything else. Just use it. Can someone tell me if I am wrong?

I am going to experiment with the XR3 to make sure its going to work for me. Then I will decide if I am going to pay $300 to help the certification process. I ordered the product but have not yet received it. Dallas

16

I’ll pay the $300 bucks to help out. Has any one got any of the of bands certified, 2.4-5.8 ?
I’d be willing to pay those people some money to get those covered as well.

17

I’d be interested in participating in certification as well.

Would we need to get both AP and CPE devices put through the process, or only AP?

My opinion would be to try to get a batch deal:

RB532+XR3 - Maybe, maybe not? I guess this is now a “legacy” product that will be going away :frowning:
RB333+XR3 - This would be the one to use for omnidirectional sites
RB600+XR3 - This would be the one to use for multisector sites
RB113C or RB411 + XR3 - CPE Side

18

I though it only had to be the XR3 wireless card to pass the FCC. Am I wrong?

There needs to be a lot more clarification before people start writing checks to anyone.

We need absolute positive answers, so if you have an opinion, save it for another thread. If you have facts, based on real tangible FCC information then by all means please share it.

  1. From earlier posts it seems the routerboard and wireless card combination require certification (for whatever frequency you want certified). We assume XR3 since thats what this thread was about. Once that is figured out particulars can be applied to other freqs. I have heard other conflicting information that even a pigtail can’t be changed or the antenna. There is discrepancy of information on this, can someone clarify and provide the source for the information so I can cite it in my FCC folder I have.

  2. Every radio needs certification - not just AP’s. If there is to be a client radio – or any other combination of hardware it needs to be decided among those participating in this joint venture. Be careful with you selections, its $2000 per choice. You want XR3 with RB333 and RB600 and RB411 - $6000 It would be more economical to choose a single board like the RB333 due to it being the most flexible and middle of the costs points. The RB411 is a great economical choice too - even for backhaul use point to point. Any way, eveyone has opinions here, choices need to be ironed out.

  3. Does the rules for this freq regulate where in the US you can or can’t use it? Some freqs have coastal areas where you can’t use them. This needs to be clarified.

  4. Does the rules for this freq limit is usage in any way? (PTP / PTMP etc..)

Seems to me, Mikrotik and Ubiquity could lead in getting this stuff certified - after all they already deal with this stuff and the FCC on a regular basis. We are blindly struggling to figure out what we can do and its them who are selling the product. Must be nice :slight_smile:

Thanks, this could really be beneficial once the thread and ideas mature.

Here are the FCC regulations for 3GHz range.

Part 15 for public frequencies
http://wireless.fcc.gov/cgi-bin/wtbbye.pl?http://www.access.gpo.gov/nara/cfr/waisidx_07/47cfr15_07.html

Adding the 3Ghz public frequencies they on changed a couple things. It all fits on one page.

Part 90 for the 3.65 frequency
