No they aren’t. They will continue to use CDMA just as if Verizon will continue to use theirs. In the future, that may change to just their LTE, UMB or Wimax choices.

I only meant for their 4G deployment, not as a whole. And when I say CDMA Family, I mean the 3GPP2 Family.

There isn’t much a fundamental difference. Sprint will be going to 4G as an overlay to their current CDMA operations for their 4G choice. CDMA’s UMB isn’t really theirs and the same thing with GSM’s LTE. It uses very different transmissions. OFDM/A and MIMO. Wimax uses MIMO and OFDMA. LTE uses OFDMA/MIMO and what is known as SC-FDMA. UMB uses OFDM/A and MIMO.
