We use a notebook computer at our racetrack for timing.  The software
we use displays the driver?s times on the screen.  I would like to
display what is on the notebook monitor screen on a monitor screen in
the pits.  The pits are 300ft away from the timing computer.  What
equipment do I need to display the timing data on both monitors?

I'd say install a wireless network card in the laptop, put an access
point and a second computer in the pits and use remote desktop
software like VNC to display the laptop's screen on the pit's computer
monitor.

Will the wireless network card transmit 300+Ft?  This has been tried
and with the fences and trailers the signel dose not alway get
through.

I just check tigerdirect and you can get a 300' cable for abour
$60.00. Just run it through a wall and pipe it underground to where
you want it. If the exact distance is 300 foot I would consider buying
a larger cable.

Wireless networking.
Q7 Should I use Wireless Networking Equipment?
Wireless Networking has become very popular over the last few years as
the equipment to install one is easily affordable at around £80 for an
access point and £30 per PC adaptor. Wireless Networking is therefore
set to replace conventional cabled networks completely in the near
future - or so its proponents would have us believe. I don't think so
but I may well be proved wrong. Mobile phones use a similar technology
and have already exceeded the number of landline phones in Finland and
could soon do so in the UK.

Wireless Networking is certainly useful when:-
   It's very difficult or expensive to run cables - such as between
buildings separated by a public street. (Wireless Networks work well
within a 100ft range and, with a good aerial, can operate up to 300ft
or more.)
   A network installation or extension is only needed for a few weeks or months. 
   You have laptop users who want to roam around the office while
remaining connected to the network and Internet.

Wireless Networking its not without its problems:-
   The maximum speed of Wireless networking devices is 56mbps (many
only operate at 11mbps or 22mbps) compared with cabled networks that
usually operate at 100mbps with 1000mbps gradually becoming the norm.
A Wireless Network's bandwidth is shared between all the PCs accessing
it at any one time while, when using network switches, cabled networks
allow full-bandwidth point-to-point connections between any two
computers.
   You can't get a simpler, more reliable connection than copper
wires. Wireless Networks are inherently more complicated and subject
to interference and poor reception problems. The frequency range used
by wireless networking, 2.4 gigaHertz, is used by many other devices
such as cordless phones.
