Plano, TX | Spectrum is the key Most operators utilize FDD spectrum (frequency division duplex) in auctioned buys. That means spectral transmit and recieve are separated on different channels.
Sprint has a significant holding in sprectrum that is TDD (Time division duplex). Meaning the transmit and recieve are on the same channel and you give time to get transmit and then give time for the uplink.
LTE is currently a FDD technology, not slated to be built for TDD for 2 years.
WiMax is a TDD technology intrinsically so was a perfect match for the spectrum holding that Sprint/Clearwire owns.
May not be as difficult an answer as some think. |
