Hmmm. I don't think wireless speeds will keep up with wired, or Fios, speeds. Or reliability. But I still think it's a great field for Dish/Echostar to enter.
It really is a question of if the wired groups are willing to provide more bandwidth for a reasonable price. Thus far they are not. This is leaving a massive door open for an aggressive wireless provider. Currently the cable companies and the wireless companies are happy with the pies they are carving out as evidenced by their unwillingness to compete against each other. (both setting artificial caps on bandwidth, both using similar pricing models). If a player would come to the market with an aggressive pricing strategy and they are able to have wide national coverage, they have a good opportunity to acquire significant market share. 1st generation LTE services today are providing data rates of over 7Mbps and some reports regular 14-18Mbps rates all with low ping times. Price it right and that beats cable easy and way beyond DSL. Fios is too limited to be in the comparison.
