SharkRF openSPOT is a standalone digital radio IP gateway designed mainly for amateur radio to reach DMR, D-STAR and C4FM/System Fusion networks
As digital radio is becoming more popular with amateur radio enthusiasts there is one limitation that is becoming more obvious. Radios, Repeaters and digital radio standards do not talk to each other.
Radios such as Icom and Kenwood support the D-STAR digital standard whilst Yaesu only supports System Fusion (C4FM) and then there is also DMR itself which leans more towards commercial radio use. To make matters worse I may have say a Yaesu radio but my local repeater tower only supports D-STAR or no digital at all.
So what the openSPOT does is it acts as a local compatible repeater. So my Yaesu radio would see it as a System Fusion (C4FM) compatible repeater connected via local UHF signal, and the openSPOT is in turn connected to the Internet and will connect to supported digital networks all around the world. It has built-in WiFi so will get its Internet connection via home WFi, your mobile phone or an Internet cafe.
My radio -> UHF -> openSPOT -> 2.4 GHz WiFi -> Internet -> Remote Repeater -> Remote Radio
The openSPOT2 uses very little internet traffic. Depending on the active connector, the data rate estimates are as follows:
* Quiet channel is 36-180 kB / hour
* Active channel is 3-6 MB / hour
