How to Use RoIP in Commercial Communication

"Hey boss, I tried to call Jimmy on the radio but he didn't respond. I called him on his cell phone and he said he didn't get the radio call. Can you fix our radios to help us talk when we need to?"


Little Construction Guy on RadioHow can the boss help out Jimmy, Frank and the rest of the radio users communicate when necessary? The solution is as simple as RoIP (Radio over IP). 
"Frank, I'll see what I can do to help you and Jimmy communicate. Do you know anything about this RoIP communication deal?"

What is RoIP? In our past blog, Radio over IP - What is it?, we defined Radio over Internet Protocol (RoIP) as a two-way communication method which involves trans-reception of radio communication signals over internet protocol (IP).

Why 220 MHz for Amateur Ham Radio, V2.0?

Why 220 MHz for Amateur Ham Radio, V2.0?

220 MHz amateur radio boasts of a long and colorful history, affording it a special place in the hearts of amateur radio enthusiasts. 

Conceptually, amateur radio repeaters are not too different from public safety devices (fire, first response, police) or those in use at federal, business or military services. However, they are often assembled (power supplies, transmitter, receivers, antenna etc.) or commercially packaged to operate only within amateur RF (radio frequency) bands, like 222-224.995 220 MHz band.

History

The Federal Communications Commission (FCC) approved VHF bands as early as 1938, one of them being 1.25 meters (224 MHz) band. Amateur radio activity spiked rapidly in 1960s and 1970s, as 2m and 70cm bands swiftly rose to prominence in the hobby. The commercial spectrum of the VHF and UHF bands became the backbone of emergency service communications like police, fire and ems. The 1.25m band however, escaped the commercial popularity - partly due to lack of enough commercial frequency allocations. Add to it, commercial radio equipment for the band has been scarce. Amateurs willing to go live on this band have had to build their own equipment or buy specialized amateur radio equipment from designated manufacturers.

Repeater Basics: What is a 2-way radio repeater and how is it used?

Repeater Basics: What is a 2-way radio repeater and how is it used?

What is a Repeater?

In the world of modern communication there is an ever increasing need for providing higher outreach. The traditional portable radios offer limited coverage area. However, a dedicated transceiver can help us achieve the requisite coverage.

A repeater is essentially a communication device which acts as a link between two radio operators to cover a large area. If you need a large coverage area like your 50,000 acre ranch, city, county or even an entire state, a repeater system comes in handy.

How it Works?

It is a two-way radio frequency communication system which receives a frequency from portable two-way radios, and re-transmits it at another frequency in real-time, albeit at a higher wattage than typical portable radios. This mechanism allows repeaters to broadcast to a much wider reception spectrum. Since it is capable of both transmitting and receiving at the same time, it is also called a ‘Transceiver’.
