4. A note on other wireless networks.
There is a tool available as freeware known as “network stumbler” This is a
PC based package that allows you to discover other networks which might
exist. The software is free and downloadable from www.netstumbler.com.
The software can be run on a laptop and shows instantly what channels
are in use, the signal to noise ratio of the devices in question etc. It is
highly recommended that this program is run on a wireless capable laptop
at show time to show the presence of any other wireless networks.
5. Running a show
To enable maximum flexibility at show time it is recommended that a
wireless networked enabled laptop is present and running both the WAP
configuration software and the latest version of netstumbler. This allows
for identification of rogue wireless networks and offers the instant ability to
switch channels instantly.
At the end of the day the likelihood of interference depends on where you
are in the world. A wireless networks convention would not be the place to
use a wireless network without the ability to switch channels instantly.
Conversely an outdoor festival on an airfield would be ideal. The level of
protection that you afford is dependant upon how much safety equipment
and backup you deploy, if a cable can be run safely then this will
inherently be more secure than any wireless system, however if there is
the risk of damage to the cable or running it is impossible then the eDMX
system gives you a highly secure system.
