Lightsquared had 30 wholesale customers even before their network was built! http://www.businessweek.com/news/2011-12-12/lightsquared-reaches-30-customers-as-service-still-faces-hurdles.html Clearwire ($CLWR) has a WiMax 4G network built already and they will have an TD-LTE network in 2013. They got 2 customers already, with FreedomPop and LEAP...I'm sure the other 28 will move to $CLWR soon as well.
