Subject: Re: [WISPA] Modifications of Parts 2 and 15 of the,Commission's
Rules for unlicensed devices and, equipment approval
Under the normal Part-15 rules, the only devices allowed to have a "non
unique" connector are devices labeled for and sold only to "professional
installers".
The problem is, there isn't really a good explanation of what a part-15
professional installer is.
What I've been told by the FCC is that the intent is that any device where
it's easy to mix and match parts (remember that you could only use
specifically certified antennas before 2005) was to only be sold to a pro
installer. Literally, it was illegal for a vendor to sell us an ap
without also including the cable and antenna for it.
To be a pro installer we're supposed to have been manufacturer trained on
a specific piece of gear (I was trained on p-com and wmux gear in the bad
ol' wpcs days). The reasoning was that it's possible to use a certified
combination of radio, cable, and antenna, and STILL exceed the EIRP
limits. So we're supposed to have been trained on the device so we'd not
accidentally assemble and configure an illegal version of a legal kit.
up to here I agreewith you.....
The new rules specifically say that these rules do NOT apply to a device
designed for a professional installer. If you're not sure that your
device is for a pro installer, look in the manual. If it's got an n
connector on it, it should also say that it's only available to
professional installers.
***************************************************************************************
From the new rule:
4. The modular transmitter must comply with the antenna requirements of
Section 15.203 and 15.204(c). The antenna must either be permanently
attached or employ a "unique" antenna coupler (at all connections between
the module and the antenna, including the cable). Any antenna used with the
module must be approved with the module, either at the time of initial
authorization or through a Class II permissive change. The "professional
installation" provision of Section 15.203 may not be applied to modules.
In other words it MUST ALWAYS have a unique connector
***************************************************************************************
This from part 15 says that the "unique" conector is NOT required if
intended for a "professional installer" The "N" connector is considered a
"unique connector"
Section 15.203 Antenna requirement.An intentional radiator shall be designed
to ensure that no antenna other than that furnished by the responsible party
shall be used with the device. The use of a permanently attached antenna or
of an antenna that uses a unique coupling to the intentional radiator shall
be considered sufficient to comply with the provisions of this Section. The
manufacturer may design the unit so that a broken antenna can be replaced by
the user, but the use of a standard antenna jack or electrical connector is
prohibited. This requirement does not apply to carrier current devices or to
devices operated under the provisions of Sections 15.211, 15.213, 15.217,
15.219, or 15.221. Further, this requirement does not apply to intentional
radiators that must be professionally installed, such as perimeter
protection systems and some field disturbance sensors, or to other
intentional radiators which, in accordance with Section 15.31(d), must be
measured at the installation site. However, the installer shall be
responsible for ensuring that theproper antenna is employed so that the
limits in this Part are not exceeded.
******************************************************************************************
That rule has been TOTALLY ignored by everyone. We are, as users of this
gear day in and day out, assumed to be professional installers so we don't
have to buy devices with only unique connectors or buy only in kits (like
a Linksys dsl router etc.).
TRUE..... all radios are to be sold with cable and antennas
Again, I'd LOVE to see a real mix and match capability where we could use
anyone's radio with anyone's amp and antenna. But they clearly aren't yet
ready to go there.
The mix/match can still ONLY be with antennas that were certified with the
radio module / firmware.....
Just to make sure I'm reading this correctly, I've asked for some time
with the head of OET (the FCC folks that write these rules). I'll pass
along what he says once I'm able to talk to him about it.
Thanks, looking forward to response.
Hope that helps,

I saw nothing about an N connector being disallowed. It simply says
that the connector(s) must be unique, and my contention is that an N
connector is just as unique as a U.FL or RP-SMA. Once something
becomes an Industry Standard it sort of loses its uniqueness.
Since every system must have an antenna and for maintenance purposes
that antenna must be removable. Just try and unsolder an antenna lead
while hanging off a tower. I doubt that is their intention and thus
they would certainly allow a removable antenna.
I do agree that they are worried about the consumer gear and having
Joe Schmoe hook up a larger antenna to his Dlink, LinkSys or Zcom
consumer router.
For the ISP market the rules must have a bit more common sense, and I
did see that in the document. I felt it was a very positive step and
one that will help the Industry in general.

I certainly DO want to mix and match. Hell, it's going on all over
anywhere, they're gonna have to legalize it sooner or later anyway. The
mix
and match "thing" is way beyond anyone's ability to enforce it anymore.
However, it's still the law and shouldn't be done.....
This is the specific clause that applies to us:
The "professional installation" provision of Section 15.203 may not be
applied to modules.
If it's got an N connector on it, as does most of our gear, it's for
professional installation only.
This new ruling is clearly aimed at the Dells, HPs, Toshibas etc. of the
world. Not at us. If you can find a source at the FCC that'll say
otherwise I'd LOVE to hear from them. 90% of the networks out there
have
changed something that will take them out of compliance, this rule would
bring almost all of them back into compliance.
