Question: Which of the following UTRA/TDD frequency band options ONLY includes a specific subset of frequencies for the 1.28 Mcps TDD option, differing from its general uplink and downlink transmission range?
Option 1: Band c) 1 910 – 1 930 MHz
Option 2: Band a) 1 900 – 1 920 MHz & 2 010 – 2 025 MHz (with a specific condition for 1.28 Mcps TDD)
Option 3: Band e) 2300—2400 MHz
Option 4: Band f) 1880 - 1920 MHz
Explanation: The correct answer highlights that for Band a, only the frequencies 2010 - 2025 MHz are used for the 1.28 Mcps TDD option, demonstrating a specific condition altering the typical transmission range for this particular TDD option within Band a.
