Two Way Radio System

The radios are hand held and when cued in close proximity to the laptop the lap top crashes

Computers are electrical equipment and susceptible to interference. Try using the radio next to an LCD TV. or a hi fi to see if you pick up interference.

This radio is cool...... Houston Communications Inc 1-866-406-7688 www.houstoncommunications.com

By wireless, I mean wireless earpiece and mic....

Preferably? What, you are considering a system with wires? That might prove to be problematic.

Joking aside, what are known as PMR446 radios are available in the UK and have a range of between one and three miles. I think that should be more than adequate. You can identify them by the fact that they will have 8 channels and 38 subchannels.

Especially good for volunteer fire and ambulance departments with a limited budget (work as good as products from Motorola or Siemens but cost 1/5th the price).

then, do you need to run a loop? How far can you go before you need a splice?

I really don't remember the exact length a single or multi-mode fiber can be run before needing a splice. I am sure that youcan find that answer in google under fiber specifications. Or TIA/EIA fiber specs. I do know that it is a very long distance.

Price: $99.99

New Advanced Digital Technology gives you Private and Secure Communications, no eavesdeopping and cannot be scanned
10 Billion Channels

SMS Text Messaging between Radios

That all depends on what you want to do with the two-way radio systems. You can get a couple of cellphones for next to nothing ... they use UHF.

As for detailed tech specs: you have to be much more specific what you're looking for. But you already (ought to) know that if you're serious.
