Has anyone found a solution for a stand-alone WIMAX 4G Repeater / amplifier? I only get 0 to 1 bars of 4G at home on the EVO even though I'm in a geographic 'best' coverage zone and am trying to find a way to amp this up to be usable. Searching around I've only found ones that are super expensive (commercial grade, $2000+) as opposed to CDMA repeaters that run $200. Stopped at the sprint store today and they have nothing available and have not heard of anything coming. Clear also does not report any devices being available.
