Brad ‘RenderMan’ Haines is one of the more visible and vocal members

of the wardriving community, appearing in various media outlets and speak-

ing at conferences several times a year. Render is usually near by on any

wardriving and wireless security news, often causing it himself. His skills have

been learned in the trenches working for various IT companies as well as his

involvement through the years with the hacking community, sometimes to

the attention of carious Canadian and American intelligence agencies. A ﬁrm

believer in the hacker ethos and promoting responsible hacking and sharing

of ideas, he wrote the ‘Stumbler ethic’ for beginning wardrivers and greatly

enjoys speaking at corporate conferences to dissuade the negative image of

hackers and wardrivers.

His work frequently borders on the absurd as his approach is usually

one of ignoring conventional logic and just doing it. He can be found in

Edmonton, Alberta, Canada, probably taking something apart.

Michael J. Schearer is an active-duty Naval Flight Ofﬁcer and Electronic

Countermeasures Ofﬁcer with the U.S. Navy. He ﬂew combat missions

during Operations Enduring Freedom, Southern Watch, and Iraqi Freedom.

He later took his electronic warfare specialty to Iraq, where he embedded

on the ground with Army units to lead the counter-IED ﬁght. He currently

serves as an instructor of Naval Science at the Pennsylvania State University

Naval Reserve Ofﬁcer Training Corps Unit, University Park, PA.

Michael is an active member of the Church of WiFi and has spoken

at Shmoocon, DEFCON, and Penn State’s Security Day, as well as other

forums. His work has been cited in Forbes, InfoWorld and Wired.

Michael is an alumnus of Bloomsburg University where he studied

Political Science and Georgetown University where he obtained his degree

in National Security Studies. While at Penn State, he is actively involved in

IT issues. He is a licensed amateur radio operator, moderator of the Church

of WiFi and Remote-Exploit Forums, and a regular on the DEFCON and

NetStumbler forums.

Exploring Past

Discoveries That Led to Wireless

Wireless technology is the method of delivering data from one point to another without

using physical wires, and includes radio, cellular, infrared, and satellite. A historic

perspective will provide you with a general understanding of the substantial evolution

that has taken place in this area. The common wireless networks of today originated

from many evolutionary stages of wireless communications and telegraph and radio

applications. Although some discoveries occurred in the early 1800s, much of the

evolution of wireless communication began with the emergence of the electrical age

and was affected by modern economics as much as by discoveries in physics.

Because the current demand of wireless technology is a direct outgrowth of

traditional wired 10-Base-T Ethernet networks, we will also brieﬂy cover the advent

of the computer and the evolution of computer networks. Physical networks, and

their limitations, signiﬁcantly impacted wireless technology. This section presents

some of the aspects of traditional computer networks and how they relate to wireless

networks. Another signiﬁcant impact to wireless is the invention of the cell phone.

This section will brieﬂy explain signiﬁcant strides in the area of cellular

communication.

Discovering Electromagnetism

Early writings show that people were aware of magnetism for several centuries before

the middle 1600s; however, people did not become aware of the correlation between

magnetism and electricity until the 1800s. In 1820, Hans Christian Oersted, a Danish

physicist and philosopher working at that time as a professor at the University of

Copenhagen, attached a wire to a battery during a lecture; coincidentally, he just

happened to do this near a compass and he noticed that the compass needle swung

around. This is how he discovered that there was a relationship between electricity

and magnetism. Oersted continued to explore this relationship, inﬂuencing the works

of contemporaries Michael Faraday and Joseph Henry.

Michael Faraday, an English scientiﬁc lecturer and scholar, was engrossed in

magnets and magnetic effects. In 1831, Michael Faraday theorized that a changing

magnetic ﬁeld is necessary to induce a current in a nearby circuit. This theory is

actually the deﬁnition of induction. To test his theory, he made a coil by wrapping a

paper cylinder with wire. He connected the coil to a device called a galvanometer, and

then moved a magnet back and forth inside the cylinder. When the magnet was
