The backbone of the scanning system is a Sony Vaio Laptop.
Specs: PII 366, 128megs ram, 12.1in. display, 1in. thick, 3.5lbs.

Just like your parent's ethernet card, but signals are transmitted in the 2.4GHz range instead of over physcial cable. Once a wireless LAN PCMCIA card is placed into the laptop, we are ready to start receiving wireless network signals.
The software that makes wardriving work. As the program scans for wireless networks it logs each unique signal it receives along with a variety of other information about the network. See the Procedure section for more details on our use of the software and get the complete scoop at Netstumbler.com
ANTENNA - Orinoco 10dbi Omni-Directional
To boost the wireless signals detected by Netstumbler, a 10dbi omni antenna was connected to the wireless network card. The antenna was mounted proudly atop the vehicle to maximize signal reception. An omni-directional antenna is preferred over a directional for mapping, as the antenna's orientation does not effect the received signal.
GPS - Garmin GPS II Plus
After connecting a Global Position System (GPS) unit to the USB port of the laptop, Netstumbler can log geographic coordinates along with each wireless network signal it detects. An external antenna was connected to this unit and mounted outside of the vehicle for more accurate signal reception.

TRUCK - Dodge Dakota
Load all of the above gear into a pickup truck and you have a complete mobile scanning unit that can map almost any network you throw at it.
Specs: 1993 V-6 with 113,712 miles (02/05/2002), maroon and tan exterior, brown interior, stock stereo, new radiator, new battery, four 80lbs. sand bags, white aluminum topper and one small American flag for solidarity.
