Answer: Please see reference material below for a more in depth understanding. However,
here is the layman's version.

The WIFI-X-TENDER acts in 3 ways physically with the RF signal, impacts the Quality of
the NETWORK packets.
It allows tuned RF frequencies in the public spectrum to pass thru it in one direction
blocking others.
It reflects tuned RF frequencies in the public spectrum in the opposite direction
allowing others to pass thru it.
It acts as a Waveguide.

This accomplishes two things:

1. It allows the RF signal to pass thru it while blocking RF signals outside of the public
spectrum effectively reducing the RF noise floor.

2. It reflects RF signals in the public spectrum back to your WIFI/Cell phone antenna
that miss the antenna effectively adding more signal strength to the received signal
at your antenna.

How this works:

1. The RF noise floor is the amount of ambient RF noise or unwanted signal that
surrounds us all the time, from radio stations to ham operators etc.

2. This is referred to often as the SNR or Signal to Noise Ratio expressed in db, yours
may be anywhere from -60db to -90db as an example.

3. The RF frequency that you wish to receive is also referenced in db and may also
be in the range for example of -60db to -90db.

4. Please note that db (decibels) is very unusual in how it's calculated as it is an
algorithmic equation. So for example if I change the db of the signal I am sending by
3db towards the positive side, I have effectively increased the signal strength by 100%.
Conversely if I change the db reading towards the negative side by 3db I have reduced
the signal strength by 100%.

5. So what does this really mean to you. Quite simply put if we can reduce the ambient
RF noise by 1db IE go from a -90 SNR to a -91db SNR then we have reduced the ambient
RF noise by 33%. Also at the same time if we can increase the signal strength by 1db, IE
go from receiving a signal at -90bd to -89db, then we have increased the signal strength
by 33%.

6. So it is clear ( if you really want to understand db please see the reference materials
below) that we only need a small change in db on both the SNR and the Signal Strength
to really improve the RF portion of the equation by quite a lot.

The other portion of the equation, NETWORK packets.

1. All computer and cell phone WIFI signals are really transmitting data packets.

2. These data packets are formed in a very particular fashion, and must arrive at their
destination intact or they will be discarded.

3. Discarded packets on a cell phone sound like you are underwater or there is a lot of noise,
or even you hear the caller's voice disappearing and coming back, but packets are getting
thru to maintain the call.

4. Discarded packets for a computer have to be resent as they use TCP/IP and this
Transmission Control Protocol (TCP) ensures that the data that was sent is the data
that was received. If a data packet is discarded, then it has to be resent, this resend
(and when this happens, it happens a LOT) will reduce the overall performance of your
wireless network, reducing your thru put and making the network seem very slow.

Putting it all together:
1. So now we know what the elements of the problem are and the solutions we should be
able to take a look at what's happening.

2. By reducing the db of the signal we want closer to zero and increasing the db of the SNR
farther from zero we are creating a better quality signal.

3. This better quality signal allows more data and or cell packets to make it their destination
improving call quality and data reception by reducing retries.

4. Combined these can significantly improve your reception.

So what can you expect to see: DATA

1. If you are receiving a poor quality data signal and are connecting to a WIFI hot spot or
your home AP and are connecting at 6Mbps, you can expect to see an increase in your
connection speed anywhere from 12Mbps to 54Mbps, the fastest speed possible.

2. If you are already connecting at 54MBPS, you probably don't need our product, but what
you might see is an increase in the number of AP's or wireless hot spots near you if there are
any.

What you can expect to see: CELLULAR

1. Call quality will improve if you are in an area where there is poor RF reception.

2. If you have a good connection, you will see an increase in signal quality also, usually
indicated by more bars on your phone but not always.

3. Please note that each and every phone manufacturer uses a different algorithm to
calculate their BARS on their phones. This is due to the mw rating of the antenna and the
phone but basically 5 is TOPS and 0 is the worse so if you get 1 bar, you are getting a
signal, but not a good one and call quality may be poor, however you can also have 1 BAR
and call quality can be great, it really depends on the phone.

4. You should see fewer dropped calls, and improved voice quality regardless.

Decibel: A unit used to express relative difference in power or intensity, usually between two
acoustic or electric signals, equal to ten times the common logarithm of the ratio of the two
levels.

Question 1: Why does your product not work for me?

Answer: There are just some circumstances where a little more is just not enough. Since the
WIFI-X-TENDER is a passive product, it really can't overcome a very negligible or no signal
condition. Additionally there are environmental factors it can't overcome too. This is why we
have a very generous return policy. If our product does not help you, we don't want you to
keep it, and we will happily refund your purchase price, and even make a recommendation of
how you can resolve your problem if you ask us.

Question 2: Why don't you refund shipping?

Answer: We have a similar policy as every other business in this regard. We are selling the
product, not the shipping. If you want to drive over to the office and pick one up, we won't
charge you shipping. If you ask us to ship it to you we have to pay to ship it and we pass
that charge along. We try to keep it clear that the two are separate things. Wal-Mart does
not pay your gas to go to the store to return a product, neither do we. We cannot refund
shipping. Additionally, as we see on eBay for example, there are people who will going on
spending sprees's and purchase without regard to their need for the product, or to boost
their buyer/seller ratings and then just return the products unopened for a refund. We do
not wish encourage this Gorilla buyer who is actually driving up the cost of the products
to everyone else.

Question 3: Will this work on any phone or laptop?

Answer: Yes, we have sporadic reports from end users that x or y brand does not work with
it, but after trouble shooting, we usually end up finding that they have a very, very, high
SNR or too weak of a signal to do anything with and it was not the device at all. Again this
is why we have a 30 day return policy, if it does not work for you where you are needing it
to, send it back for a refund.

Question 4: Will it damage my computer or cell phone if I remove It.?

Answer: No, just clean the surfaces with a mild detergent or alcohol after you remove it.

Question 5: I got a new laptop; can I move this from my old laptop to the new one?

Answer: Yes, you will just need to be very gentle and very patient and go slowly but it can
be done, with cell phones too. Product life expectancy is about 3 years.

Question 6: Will it help if I put more than one on my laptop?

Answer: Yes it will, but one should be enough for 90% of applications.

Question 7: What's your product made of?

Answer: I'm sorry that is proprietary.

Did WIFI-X-TENDER work for me worksheet for Data.

Before installing the WIFI-X-TENDER product, fire up your laptop and go to your network
settings for your wireless adaptor and select the site monitor. In the wireless site monitor
select the SSID that is yours. Monitor the db of the SNR and Signal for a few minutes and
record the high and low for each during this time frame, say 5 minutes. Also record your
connection speed. See example below. Remember the db's will all be negative numbers, so
the higher the number the lower the signal strength and the lower the number the higher the
signal strength.

Before SNR in db High = -90
Before SNR in db Low = -91
Before Signal in db High = -79
Before Signal in db Low = -80

Connection speed before = 12Mbps

Install the WIFI-X-TENDER and monitor for 5 min and record the highs and lows the same as
above.

After SNR in db High = -91
After SNR in db Low = -93
After Signal in db High = -77
After Signal in db Low = -78

Connection speed After = 24Mbps

Then to calculate your average performance improvements do the following.

Subtract all the before's from all the afters.

SNR BEFORE HIGH = -90 minus SNR AFTER HIGH = -91 = 1
SNR BEFORE LOW = -91 minus SNR AFTER LOW = -93 = 2

Now do the same for the Signal Strength db for your site SSID

SIGNAL BEFORE HIGH = -79 minus SIGNAL AFTER HIGH = -77 = 2
SIGNAL BEFORE LOW = -80 minus SIGNAL AFTER LOW = -78 = 2

As you can see we reduced the SNR on average by 1.5 db = 48% (1+2=3 3 divided by 2 = 1.5)

We also changed the average signal by 2db = 66% (2+2=4 4 divided by 2 = 2)
After connection speed = 24Mbps minus before connection speed =12Mbps = + 12Mbps

As you can see a very small change in the average db of the Signal and the SNR equate to a
measurable change in the signal quality and connection speed. In this instance the connection
speed doubled with an increase of 3.5db total change.
