  1. While Googling about LTE, I came across this document on the FCC's website. The tidbit I found most interesting was the section on bandwidth options. It listed the standard 6 options (1.4, 3, 5, 10, 15, 20) and then the "occupied bandwidth" for each carrier size (1.08, 2.7, 4.5, 9, 13.5, 18). I'm curious as to what exactly that means, and it brings up several questions. Since the occupied bandwidths and channel sizes for 5 MHz and above are proportional, does this mean that there is no "waste" from using two 5 MHz carriers instead of one 10 MHz carrier? For example, the 5 MHz carrier would have a peak speed of exactly half of the 10 MHz carrier. Is the unoccupied (so to speak) bandwidth required to be completely empty for the channel to work properly? If not, what is stopping Sprint from using the unoccupied bandwidth for CDMA carriers in ESMR? A configuration where the LTE carrier is sandwiched between a 1x and an EVDO carrier would fit into the 7 MHz they have in most places. The .25 MHz "extra" on each end of the LTE carrier would be shared with the CDMA carriers. It would look like this: |1|.25|4.5|.25|1|. I've read about an Australian carrier doing something similar with WCDMA and GSM when they refarmed either the 900 MHz or 850 MHz band.
