2.1.2. SPECTRUM
One sector antenna has 90° coverage. Four sector antennas with 90° coverage are used to
achieve 360° coverage. Each sector can utilize up to 500 MHz of frequency spectrum in
range from 69 000 MHz to 71 0000 MHz for downstream and 500 MHz of frequency
spectrum in range from 81 000 MHz to 83 0000 MHz for upstream. System allows different
combination of sectors from a single sector setup to a fully equipped 4 sector base station.
Number of sectors can be adjusted depending on geography and customer needs and is
part of network planning.
