What this software does is to combine multiple internet connections.
I am combining a bluetooth PAN and Wifi.
Blue tooth Pan from a Sony Z3 Xperia Compact phone on EE in the UK and Wifi hotspot from another same model phone on Giff Gaff (a MVNO running on O2).
I'm doing this to get better coverage on the train between London Waterloo and the south coast of England. All operators have their weaknesses (areas of no reception), but I have found that the weaknesses occur in different places, so combining 2 networks improves the overall internet connection to an extent.
