Point
Mapping
Prior to the visualization of network fields, it is often useful to
map networks directly from the point file collected by Netstumbler.
This technique has already been used by many 'stumblers to map network
locations upon a vector road map. Here, we use aerial photography
as a background due to its visual appeal and easy interpretation. |

This image shows a large collection of wireless networks detected
while driving in Lawrence, Kansas. Each unique hardware address
is indicated by a different colored point. The left column shows
a subset of these MAC addresses.

Individual
Network
Using
the techniques documented in the Procedure
page, the point data collected for a single network may be represented
as a signal strength field.

Multiple
Networks
If many networks are located in close proximity to one another, they
may all be mapped within the same scene. |

Multiple
Access Points
It is also possible to map multiple access points (AP's) for the same
network. This is accomplished by subdividing the network by the unique
MAC addresses (provided by Netstumbler) of each AP.
Note: these maps were created with a walking scan for finer resolution. |

Small

A single network composed of nine access points (AP's). Each
AP is denoted by an asterisk. The complete network coverage
is shown by the shaded area while the unique field for each
AP is bounded by its respective color.

In this image a single AP is isolated from the network and
a signal strength field is shown for this device.
