Mobile broadband is becoming ubiquitous throughout many parts of the Americas. To meet this growing demand for mobile broadband services, operators are making plans for deployment of LTE Frequency Division Duplex (FDD) technology. It is important, however, that operators, regulators, license holders and investors closely consider deployments of LTE for unpaired Time Division Duplex (TDD) spectrum. The LTE ecosystem supports FDD and TDD operation. Fifteen paired (for FDD operation) and eight unpaired (for TDD operation) spectrum bands have already been identified by the 3rd Generation Partnership Project (3GPP) for LTE. This means an operator can introduce LTE in new spectrum bands where it is easiest to deploy 10 MHz or 20 MHz to carriers and eventually deploy LTE in all bands.
