Wireless Mouse - Is Frequency a problem for other systems nearby?

I have not been able to find enough information about the frequency
settings for a Wireless Mouse. The proposal is to have 5 computers in
close proximity. The worksurface** will be positioned on the arms of
Wheelchairs, so may be a few feet away from the Tower etc. (These will
be put in a Day Centre for disabled users to access).

I am trying to find out if each mouse has its own frequency and can
that be altered.

The thought in my mind is that there would be interference between the
different set-ups.

Would it be safer to have 5 different makes or would they be faced
with the same problem? Am I worrying unnecessarily?

** that is another issue. Does anyone know of a purpose made shelf
suitable for fitting and adjusting so that wheelchair arms can be used
to support keyboard and mouse. I can visualise making something out
of, say, laminated flooring, but wonder if there is such a product on
the market. Have been unable to find any web site selling such a
product.

All I can say about this is that I have 4 systems that all have different
ones and there is not a problem. I have one HP, I don't have the exact model
number available at this time but I will supply it if you desire, that
displays an icon in the tray indicating channel selection so I imagine that
would be useful if needed. This one I got a Big Lots for $10.00.

At one time they used 27.xx MHz, not sure if that's still
the case. Some brands like Logitech are known to have
multiple channel support, and a button on the device(s) to
sync it with the base. I don't recall if there are 5
channels, you might check Logitech's website or send them
an email.

I believe the recommended distance between receiver units for cordless
RF devices is 12 to 15 feet. Most have only a 6-foot range, fade out in
a foot or so, but have been seen to interfere with each other if within
a dozen feet or less. Bluetooth is around 30 feet for its working
range.

In a work environment with cubicles, you often don't get much more than
a few feet apart between desktops. Most times the cordless devices will
ignore each other but not always. I had a user with a roving mouse
pointer on his screen while his mouse was untouched that was caused by a
user up one floor and almost 50 feet away. Hitting the sync button on
the receiver and then the mouse/keyboard fixed the problem as it resets
them to use different ID or security codes (their frequency doesn't
change) so they won't interfere. Some brands provide a larger range of
codes than others, with some having 256 codes over 1 channel and others
having 12-bits to provide 4096 codes over 2 channels
(http://snipurl.com/logitech_cordless). If that doesn't work, you can
try using a mix of different brands of cordless devices.

If you want to standardize on one brand and model, get one that provides
a lot of security codes, maybe multiple channels, and use the sync
button on the receiver and cordless device to eliminate conflicts.
