- The APT700 band plan for using spectrum between 703-803 MHz for LTE has received strong global support from industry and regulators representing nearly 4 billion people. - The band plan uses a 2 x 45 MHz frequency-division duplex (FDD) configuration standardized by 3GPP as Band 28, with 10 MHz of guardband between the uplink and downlink frequencies. - Adoption of the APT700 FDD band plan by 42 countries has created major opportunities for near-global spectrum harmonization, increasing economies of scale for devices and improving capacity and international roaming capabilities for LTE networks.
