In current generation networks, network nodes operate by replicating and forwarding the packets they receive. In network coding, nodes operate by combining received packets. This allows for a more efficient and robust network. This project aims to build on previous research as well as develop software that can be used for future research in network coding at Iowa State..

Wireless is Global. The standard radio frequencies run in the range of 3Hz to 300 GHz. There is other frequencies used for example the 222 MHz through 225 MHz is for amateur radio. If your interested in what frequencies your country is using for what? Take a look at the frequencies.
