Mom actually doesn't live at the bottom of the valley. More like halfway up. 95th and Mission is potentially line of site except for trees, houses, etc. Strangely enough the Wimax is strongest in the southeast corner, must be because of trees. It also varies substantially by time of day, like the cells are overloaded. How many connections can LTE handle at once? Hopefully more than EVDO or Wimax. I've always wondered if it was a capacity issue.
