Is there anyway to see this type of information through a Windows based
computer. I would like the see the tx and rx bit rate.

But not necessarily in-home. Higher gain only comes from a more directive
antenna. An "omni" gain antenna has a pancake pattern.

We are deploying a DSL network, and Broadcom is the leader in the DSL
chipset market. So most all these modems we are using have a Broadcom SoC
design with the VDSL2 modem, 802.11N 2x2 MIMO, Ethernet Switch, and CPU all
built in. The only thing the modem manufacturers change is the power output

All of the UBNT AC products use broadcom.

Depending on how fancy Broadcom's 802.11 implementation is in devices being
tested, there is also the Transmit Power Control (TPC) feature of 802.11h,
although that is normally (exclusively?) intended for 5.8GHz band, i.e. as
part of DFS.

You are correct. It never will. Rx can only be improved by a bigger
antenna to listen with. Antenna gain always has and will be better than
raw power.
Unless you include the other side's Tx, in which case more power and gain
will help. In the Wifi world you're totally screwed because it's a

Awesome, I am already learning so much from this mailing list. So it sound
like the author was right. So boosting the power output on the AP will more
than likely boost the TX (downlink) speed on the AP side, but do nothing on
the RX speed side of the AP since nothing from the clients sending

Yes, radios will negotiate different rx/tx rates to each other, so up to 2
distinct rates for a single link. On the open source mac80211
linux-wireless driver you can see this explicitly. The rx/tx on one radio
is the tx/rx on the other.

In my situation, we are assuming we are dealing with a location with one
and only one AP (typical home) and most devices are tablets and smartphones
who's antenna's and power output can't be modified. Can be either a 1 or 2

So, how much truth is in this article:

Going from 20 dB to 26 dB will allow the AP to
be heard (with the same reliability) at double the distance away.
Yes. If the client power (actually the client EIRP which includes
the antenna gain) stays the same then the "uplink" distance from
client
You have the right idea. It is only when you increase power on both ends that
the distance increases.
Tablets in particular only have about 10 - 15 mW radios so that is the lowest
common denominator. If you have radios with removable antennas, you can
sometimes use different antennas to improve
So going from a regular powered 100mw (20db) to a high powered 400mw (26db)
is a 6db increase in output power. So you are saying going from regular to
high powered is a double in coverage size?
Doesn't increasing the power output at the AP only increase how loud the AP
can "shout" which in term dic

To double the communications distance
(everything else holding steady) requires an additional 6 dB.
Knowing this, you can do the math with the various antenna gains
and power levels to determine performance.

We are comparing multiple SOHO routers and modems that have the same
Broadcom chipsets. All of them have 802.11N 2x2 configuration. The only
differences between them are if they have internal or external antennas and
the gain of the antennas (either 2, 3, or 5dbi ratings). In addition, some
