Just like somebody explained long back... " lower the frequency longer the distance" ... :-))

It is a proven theory that a LTE 700 MHz is going to be a killer in case of LTE Services before 450 MHz can make a pitch in the competition. Because many of the major LTE markets are already having strong push to deploy 700 Mhz spectrum.
Both FDD/TDD modes are available in 700 MHz spectrum.
The below pictures are self explanatory of benefits/advantages over other spectrum...
