A direct and effective brand name
This is a clear and simple business name, as many of the best brand names are. There's no ambiguity to the focus here: it's all about wifi. The clever contraction of the words wifi and definitive (or infinitive), don't just give this name its uniqueness - they also add a modern character and a suggestion of quality. The bonus that the word structure is reminiscent of the word infinity adds a real gloss to this bold, contemporary brand name.
