It's a solution but it's not necessarily easy. There seems to be the mistaken belief that WiMAX was developed for rural areas. It was originally developed (just like LTE) for metro areas. It has been found that it (Revision E) works reasonably well in some rural areas but those towers, equipment and radio spectrum are not inexpensive. Once those towers are both in place and paid for it becomes a relatively inexpensive "last mile" solution.
