Two Way Radio Communication over 100 miles from antenna

A client utilizes two-way radio communications in the field. The headquarters is located over 100 miles away from the antenna and repeater. Is there a way to put a base in the headquarters that would be able to communicate live over the two way radio? I've heard of an internet solution, but not much more than that. Does anyone have any suggestions on if I posted this correctly? The reason for two-way radios is there is hardly any cellular phone coverage, and the ease of use for field employees using two-way radios.

You want to put another repeater at the office is that what you are saying? I don't follow what you mean by base.

I guess what I meant was a receiver and the ability to communicate back. Like hear what they are saying and communicate back over the two-way radio signals. I am not sure what radio band we received from the FCC but I can find that out, although for this it shouldn't be relevant. By base I just mean like a microphone and speaker. I think the internet solution used tunneling. I am dumbfounded when it comes to this kind of communication issues.

Also the reason we do not want to install repeaters is because of cost issues. It would be very expensive to install a repeater on say 5 towers due to licensing and leasing fees.

You may still have to license the transmitter at the office, but I don't see why you cant. Just get elevation on the antenna and a powerful amp should improve things. May be one repeater or two. Thing is it just depends on the power you are transmitting.

Don't you think that would be an issue with licensing though? Because it's not like it is communicating directly to the next repeater which is over 100 miles away. Are in the Appalachian Mountains. So it is rather hilly.

I would think a satelite internet link would be a much more affordable solution than maintaining your own 2 way radio system of repeaters. Do they currently have internet access in the remote location and the central office?

There is internet access at the office location where the transmitter is. But since in the field the employees are constantly changing locations, it is difficult to say if they will have internet on a given basis, and my experience with satellite is that if there is any cloud or precipitation you're screwed.

It might be worth giving satellite another look. They have come a long way in the last few years. I used a satllite phone last year and was very impressed with the quality even in cloudy and rainy conditions.

If you only need 2 way radio and it is around 100 miles then a 2m Radio solution might work. You would need a radio specialist to do a site survey in order for you to get a hard estimate for equipment. It also depends on how important communication is. If it is critical that communication is always available in a huge area it will cost much more than a solution to work in most areas.

2m radios require a license to operate but it is not terribly difficult to pass the operators test. The radio's themselves are not very expensive (you can get a good one around $350 - $500).

Here is a link to the wiki on the 2m radio band.
