Just wondering what the difference is between what UNW offer, and what SKG offers now through BigAir Australia as announced yesterday.

Both offer wireless broadband in the city of 10mps using wirelss technology. Obviously SKG and Big Air have a much larger footprint in terms of presence, revenue and size than UNW. As of yet, UNW have done very little business. Only $300k revenue as of last report. Thats not much for a $250 million company.

What am I missing? SKG and BigAir seem to be well ahead of UNW, yet UNW have share valuation of $250 million but SKG only around $14 million.
