Actual WiFi performance is highly dependent on the environment
you are connecting in. These 3 case studies performed by hField
Technologies demonstrate the Wi-Fire's performance as compared
to a state-of-the-art internal laptop adapter in different situations
you may use WiFi.
Wi-Fire enables you to connect to
your home or small office access point from outside the building,
from another home or office, or from your neighbor's pool.
In this study, Wi-Fire was used
to connect to an access point inside a frame and brick rural home
surrounded by many trees and hills.

| A1: 200 feet from AP |
Reception displayed by Windows XP
was one bar and the connection was
indicated to be at 1Mb/s. But normal
browsing was prohibitively long and
downloading video appeared
impossible. |
Wi-Fire connected at speeds varying
from 24 to 36 Mb/s showing a signal
strength at this location of -74 to -
77dB. Both browsing and video were
very similar to a wired broadband
connection experience. |
| A2: 490 feet from AP |
Could not connect.
Signal strengthshowing at -93dB but access point could be
detected only intermittently. |
Connected at -77dB
and 24Mb/s. Browsing was a normal high speed experience and
video streamed in. |
Use Wi-Fire's range extending, signal
enhancing performance to connect to your college's WiFi network.
This example is taken at a college
in a small city. The Access Point is located on the university
campus, directly outside a campus building. hField tested both
a Wi-Fire and normal internal adapter at three test points (C1-3)
in the neighborhood surrounding the university.

With Wi-Fire |
| C1: 420 feet from AP |
Connected at 18Mb/s and
-80dB. Experience was normal. |
Connected at -75dB and
36Mb/s. Experience was normal. |
|
C2: 880 feet from AP
|
Connected at 5.5Mb/s and
-93dB. Browsing was possible but very slow. |
Connected at -82dB and
varied from 36 to 48Mb/s. Browsing and video was normal, video
streamed in seamlessly. |
| C3: 630 feet from AP |
Could not detect access
point. Windows XP detected two access points in the area but
not the target. |
Wi-Fire displayed -84dB
for the target access point. Wi-Fire detected 36 access points
in the area. |
Wi-Fire maintains fast and reliable connections
even in settings with severe obstructions like brick or concrete block walls.
In this case study, Wi-FIre was used to connect to an access point located
in a heavily partitioned building with internal and external walls of concrete
block/masonry construction and limited windows or other side wall openings.
See below how Wi-Fire helps you get connected
even while taking a break outside on a nice sunny day.

B1: 130 feet from AP |
Connected at -92dB and
2Mb/s. Browsing was slow but okay. Video varied from slow
to unbearably long to download. |
Connected at -81dB and
54Mb/s. Quite normal experience including streaming video. |
B2: 130
feet from AP
Note: This is the same point as B1
but with the Wi-Fire pointing at 90 degrees counterclockwise
from the line of sight. This is a
simple exercise to demonstrate the value of wireless signal
reflections in almost any situation where you may have many
obstructions. |
Same as above. |
Connected at -90dB and
11Mb/s. Browsing was normal. Video took slightly longer to
download but playback was seamless. |
B3: 360 feet from AP |
Could not detect access
point. |
Wi-Fire connected at 2Mb/s
displaying a signal strength of -92 to -93dB. Browsing was
still normal. Video was slower in loading but downloaded continuously
and started playing seamlessly. |
B4: 130 feet from AP |
Spurious detection, displaying
-95dB. Could not connect. |
Connected at 18Mb/s showing
-82dB. Browsing and video experience was normal. |
B5: 130 feet from AP |
Could not detect access
point. |
Connected at 2Mb/s showing
-94dB, often a minimum for satisfactory performance for those
used to a broadband connection. Browsing was normal but video
loaded very slowly, with buffering slow enough to cause playback
to pause occasionally. |
