 The
Wardriving package is intended for
road warriors who drive around looking for hotspots and wireless
networks. Most WiFi devices available in the market offer a gain of 15dBm (or 25mW), which
could do a pretty good job if you are close to an access point nearby, but hardly
capably of maintaining a wireless connection from blocks away or
sometimes even
just opposite the road.
The TurboTenna 007GT
is a +12dBi directional antenna with a beam
 width of 30 degrees capable
of picking up the WiFi signals from a remote spot. You may scan the signals
by slowly changing the beaming direction until you capture the cluster
of SSID with the strongest and stable signals. The lower diagram shows
that 23 SSIDs were captured by the TurboTenna at channels 1, 4, 5 , 6,
10 and 11, an excellent accomplishment for a low-cost high performance
antenna. The green SSID indicates a pretty good signal strength for
stable connection; yellow gets a bit speed bump yet still stable; both
orange and grey are borderline that needs a bit of steering to get a
working
 connection.
If your Centrino laptop or PCMCIA adapter
does not support an external antenna, don't worry! The Buffalo
WLI-CB-G54S 54/ 125MHz* High Speed Mode PCMCIA
card is one of the few in the market that does, and it works as good as
the 802.11b Orinoco Gold card with a
TurboTenna 007GT
but runs faster on its 54/125MHz High Speed Mode.
The Wardriving package consists of a
TurboTenna 007GT
with a tripod,
a Buffalo WLI-CB-G54S 802.11b/g PCMCIA card and a 6Ft LMR-100A RF
cable. Other sizes and types of pigtails and RF cables are available.
Setup is simple, you can install the Buffalo card to your laptop and
connect to the TurboTenna 007GT
using the RF cable. Some users told us that they brought the kit along
wherever they travel, and it worked wonderfully whenever they need a
wireless connection.
So, how does the TurboTenna 007GT
different from a Yagi antenna? Why choose the TurboTenna for Wardriving?
Although both of them are directional
antennas, the TurboTenna offers exceptional performance gain and
signal-to-noise ratio, smaller in size, lighter in weight and
affordable, which are important attributes for mobility. The
Yagi, on
the other hand, is intended for point-to-point wireless signal backhaul
and fixed installation.
