It is usually easy to be perplexed at the beginning.
I googled for development board, and found such companies as phytec, Micetek, embeddedplanet etc. MT8572-N provided by Micetek, including MPC8572 processor card and Type-N carrier, is just designed for network communication application.
It my be the right one i'm looking for.
I will appreciate, too, if you offer me more choices.
