High powered USB wifi...WOW!

I'm typing this on my neighbor's wifi about 8 houses up the street I
can't even see on the netbook's little internal peanut whistle of a
wifi/antenna. He's already ordered his new Alfa just like it...(c;]

We have 12Mbps/2Mbps bandwidth from the same provider. The new Alfa
connected to his 802.11g Netgear with space diversity antennas easily
maxes out his bandwidth on speed tests. Google News simply goes blink on
his wifi up the street just like my wifi 8 feet from the adapter.

I'm headed out to do a little wardriving tonight to see how she does on
the road. GIF at 11.

POWER and a real antenna really ARE better....no doubt about it!

Install to WinXPSP3 was very easy. The new interface software has very
extensive interface with the device making antenna positioning MUCH
easier than the crapware Windows comes with. It graphs everything and
gives you real information on the radio and data statistics. Also very
nice.

No problem powering it from Samsung NC-10 netbook on ONE USB port. The
Alfa hardly gets warm...MUCH cooler than my Cricket A600 USB aircard
connected to Cricket on EVDO Rev A.

$32! I can't believe it is so cheap.

Oh, the little suction cup/big clip cradle for it is also very nice...

The Alfa-AWUS036N (get the high gain antenna) has FAR greater range than
the Alfa-AWUS036NH!

Few/no hotels or hotspots use N since it falls apart as it backs off
fast if any B/G devices are around. N may be fine for homes, useless
where there is ANY congestion!

Amazon

With 5DBi & 9DBi antenna

http://www.amazon.com/Alfa-802-11b-W...3463495&sr=8-1

Without High Gain antenna

http://www.amazon.com/Alfa-AWUS036H-...3463495&sr=8-2

Perhaps Googling "Alfa AWUSO36NH" will find better deals. I have Amazon
Prime and it's free two day shipping offsets shipping costs from many
other sources (not all).

Note the 9DBi antenna is heavy and will tip over the device or swivel
down by itself if you don't rig some support. Well worth the trivial
effort.

The standard antenna doesn't have this problem and serves all but
extreme situations.

Oops I meant Alfa AWUSO36H not NH.

The suction cup won't hold the 9DBI antenna upright without a little
assistance. (tape?)

The H model is 802.11b and g but not N, which is the NH model. The suction
cup held the 9db antenna upright 3 hours at Waffle House, tonight. Lick it
before you stick it to the window for better "hydraulic lock"...(c;]

The H model DOES have an advantage. You can buy a matching wifi router
that will only talk to the 036H adapter's command set that turns the 55mw
(actual FCC acceptance power measured only 55mw on 036H model, not 1000mw
advertised) 036H into a mobile repeater! Connect laptop to repeater, say
running off your car battery as it's 12VDC and use a webpage the mobile
router provides to tell the 036H which wifi to connect to from the car out
in the parking lot for even more range. 036NH won't talk to the mobile
router....yet.

If you go here:

https://fjallfoss.fcc.gov/oetcf/eas/...ericSearch.cfm

and enter UQ2 into the Grantee Code box at the top with nothing else
filled in, you get 17 FCC approved wifi units from Alfa in Taiwan, but not
the model numbers advertised. UQ2036NH is the 036NH model I have...two
listings with lots more information than other units made public.
UQ2AWUS036H is the 036H model information. Click DETAIL on them both to
get to all the pictures, data, schematics, etc., even internal
pictures...very nice to have. Click up the antenna both come with,
advertised as 5 dbi....but FCC has them listed as 2 dbi...another ad lie.
FCC even tested them at 2dbi because there is a limit on ERP (Effective
Radiated Power) the 9 dbi, if it is a 9dbi, would make illegal IF these
units were 1W and 2W, which they're not so it doesn't matter.

036H is on the 2nd page of the search results.

Data Alliance is where I bought my unit from. They have much more
information on these units, mostly correct except for the true output power
level FCC measured and approved. 036NH is here:

http://www.data-alliance.net/-strse-...S036NH-2000mW-
1000mW/Detail.bok

The really nice USB router Alfa makes for the 036H, but not 036NH, is here:

http://www.data-alliance.net/-strse-...-AWUS036H-R36-
wireless/Detail.bok

It's called R36. It, too, is higher than normal output power. The two
make a helluva nice combination for a mobile repeater. The router is
powered by DC and it's USB port powers the high powered USB adapter and
controls it. You logon to the R36 from your fav wifi computer, doesn't
matter if it's an iPhone, iPad, Android, Linux, Windows, OSX or Wii, then
call the router's control webpage from your browser to control which wifi
the 036H connects to. No special software driver in your
laptop/tablet/gamebox/etc., needs to be installed in repeater service. The
router also switches channels as far away from the AP channel to reduce
interference with the repeating operation, automatically. Really cool in
operation.

Router - $53
036H - $32
complete with cables and antennas.
This is the way to get long range wifi connected to locked up crap like
iphone/cellular locked devices/ipad without jailbreaking/hacking them.
Their wifi doesn't know it's a repeater.

data-alliance.net support and service is FIRST CLASS! Very fast shipping,
too.

Of course, if you want even MORE range, they have that covered, but
probably not suitable for use in a restaurant with the antenna pointed at
the next table...hee hee...(c;]

That's a monster! Longest dick on wifi!

There is yet another version of what appears to be that B/G adapter, with
yet a different name, on that site, for about a buck more, as well as a
B/G/N variant...

The b/g/n adapter has a whole different chipset, very new. It also has a
separate RF power amp the IC maker rates at +28dbm, short of the +33dbm
Alfa says it is but very respectable compared to a laptop's measily
peanut whistle.

A whole different chipset and at least with current FW, significantly
less performance (distance) than the B/G only variant. Via real distance
tests I performed to 5 access points in a wireless distribution system
at a campground) At ~1500+' the B/G was rock solid, the B/G/N connected
to 2 of the 5 points but dropped constantly. (using a 9DBi antenna).

You won't find N in most any commercial system, interference (even non
WiFi) destroys any advantage and cross channel repeaters don't work with
N. Actually, interference might be the reason the N version drops
connections, FW not falling fully back to G.

I have not tried the B/G/N version in a home environment which may have
far less interference. But my AP is close enough for my laptop's built
into to work anyway. That is when my neighbor's N with bonded channels
is not active.

BTW, inSSIDer

Is a great FREE scanning tool!

In any data radio system, the biggest enemy-of-the-thruput is multipath
propagation. On a microwave link, for instance, we get very long ranges at
quite high data rates by forming the radio link into as tight a beam as we
can logically get, trying to eliminate all radiated signals NOT pointed in
a tiny, powerful beam at the other end of the link...on both ends. Old
farts will remember those microwave repeater towers that replaced long
distance wiring before data became important. Feedhorns pointed into very
sharply focused parabolic reflectors that were huge! This kept the
feedhorn in the "dark" from stray RF. It was pointed UP, not out.

The propagation physics of RF radiation never changes, no matter how much
advertising hype and fanboi dreaming is applied. Any radio system that is
omnidirectional in nature, i.e. your wifi system, is soon eaten alive with
signals reflecting off any conductive object from a flagpole to a
mountainside. To get any speed, one only has to make the reflections so
weak they aren't readily received. So, FCC limits wifi transmitters to 1
watt, supposedly, ERP. More powerful the transmitter, the more things the
signal bounces off and just eats other channel users alive with
interference crashing the data packets that must be resent, ad nauseum.

Wifi won't work for miles....not at those speeds. The slower the speed,
the less effect propagation and reflections have on the thruput. Voyager 1
out in the Oort Cloud and beyond now sends 15bps....Fifteen bits per
second....

N will never work over any distances across the parking lot....which is why
it was invented....reduce user operating distances so we can SELL HIM
SERVICE he'd otherwise get for free....

Attenuation at higher frequencies is a bigger limitation than multipath
in many cases. That's the main reason wireless A never really caught
on. Your lucky to get 5MHz to pass through anything.

In my area Sprint's PCS frequencies grossly reduce coverage over the
800+MHz Verizon signals. Both are CDMA DATA, but we have trees and rain
around here.

There also is an issue with Voyager. A low power antenna, an antenna
beam width greater than zero, space is not a pure vacuum...

I doubt reduced range was the goal with N. Actually, it commonly has
greater range over relatively small interference free areas. It just
handle any interference well and directional antennas don't work with
it.

I haven't followed Voyager's system webpage in a few years, but last time
I did logon to it, then, both Voyagers were STILL using the SAME
traveling wave tube final power amplifier in the microwave link to Earth
and STILL using the same data cassette tape cartridge they left Earth
running in 1967!

So much for digital being better than analog. Both the TWT and cassette
tape are analog devices...(c;] Whoever made both should get an extra
NASA bonus for every year it continues to run near absolute zero. Pity
Voyagers don't have a better nuclear power plant aboard, but the greenies
were stomping their feet at the launch as it was.....
