If it isn't spec'd, I'd say go to the FCC product database. I'd look it
up for you but I think Netgear makes crap so I have zero motivation to
do the research. I've had two Netgear die. [Yes i check the wall warts.
if only the failure were that simple.] I solved that problem by never
buying their crap again. The FCC product database isn't for the timid.
However, if you can dig up the FCC ID, then research is far easier.
So far this Buffalo wzr-hp-g450h is working well, but it isn't dual
band. If you feel you need dual band, the equivalent Buffalo has its
share of detractors on Newegg. That was one reason I avoided it. Also
the dual band router don't seem to have removable antennas in general.
With the single band buffalo, if I really wanted to do so, I could turn
off the MIMO and run one port, then put on a BAA (big *** antenna).
There are less options with dual band external antennas.
Incidentally I'm running DD-WRT on the Buffalo. It is completely factory
supported. Now that I have DD-WRT, I don't think I could ever go back to
proprietary software.
Out of curiosity, if Jeff is reading the thread, can you take a 3 port
MIMO and put 3 120 degree sector antennas on it?

The Netgear ID is PY311100156
I would fire the person at Netgear who submitted that unit to the FCC.
Seriously, the heat sink is visibly misaligned. You know with 100%
certainty the inside of the unit will be photographed. Is it my
imagination, or does that heat sink simply stay attached by the heat
sink grease?
There is some mystery RTV on the some components. Perhaps the RTV near
the inductor is to prevent a buzz, but the RTV on what I assume are
ethernet filters is just weird. I'm surprised at the amount of through
hole caps (other than electrolytics). But I don't have a router handy to
compare it to. [I've tossed the busted stuff.]
On page 8, is the solder mask messed up, or is that heat sink grease
that found its way to the bottom of the PCB?
OK, 2dbi on the antenna. Still it has a respectable output exceeding 20dBm.
Incidentally, this unit isn't dual band. It also isn't MIMO, but I don't
obsess about that.
Needless to say, I'm not impressed by the build quality.
Interesting in that the PCB has much unpopulated real estate. Presumably
it is used in more than one model.

Hell no. The whole idea behind MIMO is to have multiple paths (of
slightly different length) between the access point and the client
radio. If the paths are on 3 different antennas, pointed 3 different
ways, you'll never get more than one stream. Same with beam forming.
You can't beam form unless all the antenna patterns can be overlapped.
Even worse, when the radio drops down to 802.11g speeds, it kicks in
the usual diversity receive feature, which assigns one antenna as the
"MAIN" and another as "AUX". It sits on the "MAIN" antenna and only
switches to "AUX" if there are substantial errors that resemble the
symptoms of frequency selective fading.

Last weekend, I replaced a Netgear WNDR2000 v2 with a Linksys EN2500
at a house that was having range difficulties. I also brought along
my "reference" WRT54Gv3 router with DD-WRT for testing. The WNDR2000
went about half way through a rather long (120ft) and narrow house.
The EN2500 did somewhat better. The WRT54Gv3 was about the same. Not
the best range test, but enough to convince me that the WNDR2000 has a
problem.
The WNDR3400 is similar inside:
<http://images.wikia.com/infodepot/images/d/d7/Netgear_WNDR3400_FCC1p.jpg>
Dual band, two radios, and two antennas (diversity) per radio.
Ignoring the FCC data, my experience with PIFA antennas are that they
give a gain of -2dBi (note the minus sign) at best. Usually worse.
+17 to +20dBm is the typical power output. I think you'll find that
almost all the wireless routers that have internal antennas have
roughly the same specifications for antenna gain and tx power.
The problem is that you can always trade range, speed, and error rate.
At a given error rate (usually 1 in 10^6), if I double the speed, I'll
get much less range. If I want to go twice as far, the connection
speed slows down.
<http://wireless.navas.us/index.php?title=Wi-Fi#Performance_and_Speed>
It turns out that the limiting factors of speed and range is the noise
and garbage produced by the CPU in the typical router. Also, such
things like interference and reflections have a HUGE effect. CPU
speeds and MAC layer implementation problems also show up as
performance limitations. Only a few reviewers try to test routers
under somewhat realistic conditions. I suggest you look at the
reviews under:

If there were a different station in each sector, would they get one stream
each, total speed 3x1 stream, or would the aggregate throughput still be one
stream? To put it another way, would it be one client per stream, as if
there where three APs?

MIMO spatial diversity works with a single MAC address at each end.
The access point will have 2 or more streams with the same MAC address
connected to a client radio with a single MAC address. There's no
provision for handling multiple MAC addresses at the client end. If
it's one MAC address, the MIMO chipset will combine and conglomerate
the streams into what looks like a single 802.3 ethernet connection,
encapsulated inside 802.11 packets. In order for that to work, the
client radio has to be "seen" by all the radios and antennas. With a
sector antenna arrangement, each client will only be (theoretically)
heard in one sector, and therefore only one stream will be available.
On the other foot, beam forming will work with any number of client
radios. Each one gets a peak in the pattern, with a corresponding
null in the direction of interference sources. If it's 802.11g
(non-MIMO), it will only get a 1x1 stream, but it will still benefit
from the beam forming by improving the signal strength and SNR.

Sorta. To do spatial diversity (multiple streams), you need to have
all the transmitters on at the same time. It wouldn't make any sense
to send the data sequentially on each stream, as the total thruput
would be the same as a single stream. So, it gets sent simultaneously
on multiple radios.
If you wanna do just beam forming, you only need to have all the
antennas operating at the same time, but with only one transmitter at
a time. The antennas are phased to form peaks and nulls.
To the best of my limited knowledge, spatial diversity and beam
forming are not done at the same time. I don't see any way to do both
at the same time but maybe I missed something. I don't wanna read the
IEEE specs. It turns my brain to mush.
Some clues:

I'll read the papers when my brain is more alert. For the beam forming,
it is far easier to play the phasing game during modulation (three
different modulators) and just feed the antennas without any phasing
circuits. [You can phase them simply with digital delay if narrow band,
or Hilbert transformers if you want to get fancy. Or just generate I&Q
and do phase with a vector sum.] I'm thinking back to my sonar days, but
the idea is the same. Just a different frequency and medium. The ocean
is a really lossy medium that needs to be equalized, so in a way RF is
easier.
Having all the transmitters on at the same time does match the RF safety
section of the FCC report.

I don't see a problem:
<http://www.xirrus.com/Products/Wireless-Arrays.aspx>
16 radios, 48 antennas, PCI-e(2.5Gbits/sec) interface, one box.
<http://www.xirrus.com/Products/Wireless-Arrays/XR-Series/XR-6000-Series#Specs-tab>
<http://blog.tmcnet.com/blog/tom-keating/wireless/new-xirrus-xr-wireless-array---faster-wi-fi-with-modular-pricing.asp>
You can choose a 8-slot (XR-4000 - $2500) or 16-slot
(XR-6000 - $4000) "UFO" chassis and for the radios
you can choose 300Mbps ($250) or 450Mbps ($300) radios
depending on your budget.
So, a fully loaded 16 radio access point would be $8,800.

Looks like Xirrus measures one xmitter and multiply by the number of
active xmitters. Xirrus is grantee code SK6. There are 96 items
listed.

I fished these comments out of the MPE (max permissible exposure)
calculations:
5.15 GHz Band
Four non-overlapping 20MHz channels available, or two
40MHz channels. Total EIRP in the band is restricted
to 23.0dBm. output power per radio is reduced as soon
as more than one radio is operational in the band to
ensure the 23dBm eirp is not exceeded.
So, they have power control available. Nice.
As there can only be a maximum of 12 radios operational
at any time (3 in the 2.4 GHz band, 5 in the 5.7GHz band
and 4 in the 5.15 GHz band) the total eirp for the device
is the sum of the highest eirps in each band:
# Radios and Band EIRP (dBm) EIRP (mW)
3 radios in 2.4 GHz band 36.0 3981.072
5 radios in 5.7 GHz band 33.5 2238.721
4 radios in 5.15 GHz Band 23.0 199.5262
Total EIRP 38.1 6419.3
The rf exposure calculation using an EIRP of 38.1 dBm gives a
minimum separation distance of 22.6cm (see below). The user’s
manual requires a minimum separation of more than 25cm.
Yep. Each xmitter measured individually and added together.

The bottom of my WNDR3400v2 router says FCC ID: PY311100155.
I called the FCC at 888-225-5322 to get the antenna gain & transmit power.
The didn't know what I was asking & suggested I call the OET:

It works for me. Did you put the py3 in the first box and
the 11100155 in the second?
The result is a report, completed on May 21, 2011 & submitted to the FCC
by SPORTON International Inc, No. 52, Hwa Ya 1st Rd., Kwei-Shan Hsiang,
containing a description of the antenna and chips and wiring.
This is the antenna gain that I could glean from that report:
5GHz Antenna 1 = 1.95dBi
5GHz Antenna 2 = 3.48dBi
5GHz Band 1: MCS0 (20MHz): 16.78 dBm,
5GHz MCS0 (40MHz): 16.57 dBm
802.11a: 24.48 MHz, 16.75 dBm
Never was the 5GHz conducted power greater than 16.75dBm (and it was as
low as 14.16dBm).
Interestingly, the actual tested data rates never even got close to the
claimed data rates on the box, but that isn't the topic of this thread.
I couldn't find the antenna gain for the 2.4GHz antenna.
All I saw was the gain for the two 5GHz antennas 1 & 2:
Antenna 1:
Antenna 2:
So, what do you think the antenna gain is for 2.4GHz?
Re: Where can I get the transmit power & antenna gain of the NetgearWNDR3400 router?
It uses dinky patch antennas. And it is from Netgear. I would look for
another unit.
Again, do you really need dual band? Less is more. Unless you have
interference issues, I would avoid the 5.8G units. I find the radios
aren't as good as single band 2.4G units.
I read some of the docs and they're really hard for me just to find the
antenna gain and transmit power - but I agree it's all there (somewhere).
My Netgear FCC ID is one less than yours: PY311100155
Here's what a friend told me when I mailed him the 5GHz report for the
Netgear WNDR3400v2 router.(I haven't found the 2.4GHz report yet).
1. This is the test of the 5GHz band (5150 to 5725 MHz).
2. The same antennas are used for both 2.4 GHz and 5 GHz.
Note that an antenna with a broad enough bandwidth to range from 5.15 GHz
to 5.725 GHz would have half the gain at half the frequency, and would
easily operate at slightly lower than half the frequency, because it
can't be sharply resonant and still have that broad a frequency response.
3. The antennas are just PC board traces. Roughly L shaped traces on the
PC board.
4. Conducted power is power leaked into the AC power cord in one test, and
power into the antenna in another test. The power going into the
antennas is a hair over 16 dBm when 20 MHz channels are used.
5. The 26 dB bandwidth refers to the rule that says that an emissions
outside of the band limits must be 26 dB lower than the intentional
transmission limits.
One antenna is deliberately low gain, so that links to equipment above
and below the PC board can be made. The other antenna has about 3.5 dBi
of gain in the plane of the PC board to get some reasonable distance
horizontally. Combining 16 dBm of power into a 3.5 dBi antenna gets you
19.5 dB of EIRP. Adding a bit for the 1.95 dBi gain antenna gets you a
nominal 20 dB of EIRP at 5GHz.

I suppose if you had interference on 2.4G, you could go to 5.8G. I'm
always 20db more than any nearby system. I suppose if you were in an
apartment, the margin would be less.
I still like the Buffalo that I posted about on this group. It is MIMO
with three detachable antennas. The antennas are monopoles that I run
vertically polarized. The unit supports DD-WRT. I was hacking a bit and
set up an open guest account with a virtual wireless access point,
isolated from the rest of the network. I took it down since potentially
I don't know what the hell I'm doing, but it sounds like a good way to
set up wifi for guests without having to give out passwords.
It is hard to make good dual band antennas for both wifi bands since
they are not harmonic.
Just about anything new you boy will be dual band. In my case, I have
legacy gear that I am not willing to toss, so I will be running 2.4G for
a while.

More channels than the three non-overlapping channels available at 2.4GHz,
with the proviso that your client devices are actually capable of operating
on the 5GHz band.

Yawn... The part that mentions Xirrus starts at about 7:30 and ends
at 19:20. They repeated basically the same general discription
several times. No real numbers but a fair description of what it does

UPDATE:
So far I've found from the FCC site that the Netgear WNDR3400v2 router
5GHz transmit power is 16dBm and the antenna gain is 3.95dBi for a total
EIRP of 20dB.
