1.6 Frequency Bands and Sub-bands
Much of the circuitry in the base station is common to all frequency bands,
and is therefore covered by a single description in this manual. In some
cases the descriptions refer to specific bands or sub-bands, and these are
identified with the letters listed in the following table.
In Brazil, for K band, the TB9400 is considered to be configured as a base
station with retransmission of received signals.
