Usually when you want to buy a commercial quality two-way radio for your
business, you'll be required to obtain an FCC license. You can go two
routes to obtain a license. One is you hire someone to fill out the
paperwork for you at a cost of $400-$500. The second is to try to figure
out the paperwork yourself. Of course, like all government agencies, the
FCC doesn't make things simple.
Fortunately, one nice thing the FCC did do is set aside 5 frequencies in
the VHF business band that are unlicensed. These frequencies are called
MURS which stands for Multi-Use Radio Service. MURS radios have a power
limit of 2 Watts, but that is sufficient for most applications. MURS can
achieve ranges of several miles depending on the environment it is used
in. You can also use external antennas with gain and there are base
station radios that enable you to use a variety of available antennas.
There are lots of radio-types available for MURS. Not only are there
handheld two way radios and base station intercoms, but you can also get
wireless PA systems, vandal and weather-proof wireless call boxes,
customer service call boxes, and switch monitoring devices.
MURS is very lightly used in most locations so there isn't a lot of
competition for the frequencies. However, on each frequency there are 38
"quiet codes" that help eliminate interference from neighboring radios.
You simply assign one of these codes to all of your radios and even if
there are other people communicating on your channel, your radio remains
