Description of "Infra-Red"

[pmanson]

Hi all,

I need a description of infra-red for a peice of work i'm doing at the mo.

EG. GSM - "Short for Global System For Mobile Communications. GSM uses narrowband TDMA, which allows 8 simultanious calls on the same radio frequency"

I also need to know the following about it:

If there any hardware requirements
If there are any contention ratios
The distance it can cover
Rough guestimate of cost


Cheers Guys!

Do you mean infra red as in light of a wavelength lower than red or IrDA?

IrDA i assume (As in comms solutions eg. Bluetooth, WiFi etc)

[zumbruk]

In`fra`red´
a. 1. (Physics) Lying outside the visible spectrum at its red end; - said of rays having a longer wavelength (and thus less refrangible) than the extreme red rays, specifically those electromagnetic waves having a wavelength of between 700 nanometers and 1 millimeter.
2. relating to, using, or producing infrared radiation.
3. affected by infrared radiation; as, infrared detector; infrared film.

What this has to do with GSM, who knows...

I'm creating a matrix of terminologys for all the different comms solutions at work so GSM was just an example of one I had already done.

I've already done things like VPN, Leased Lines, WiFi, GSM etc etc.

The idea is that we can give the list to the user if they don't understand what we're talking about. (When do they ever understand - All they say is HOW MUCH?!?)

You can cut it down still further...

'Matrix of terminologies (MOT)' = GLOSSARY

Nowt like English






Now, where are those TLAs?
