QoS - Quality of Service
The performance specification of a communications channel or sys-
tem. QOS may be quantitatively indicated by channel or system
performance parameters, such as signal-to-noise ratio (S/N), bit
error ratio (BER), message throughput rate, and call blocking prob-
ability. QOS is a subjective rating of telephone communications
quality in which listeners judge transmissions by qualifiers, such
as excellent, good, fair, poor, or unsatisfactory.

RF - Radio Frequency
RRU - Remote Radio Unit
RSSI - Received Signal Strength Indicator
The measured power of a received signal.
TDD - Time Division Duplex
A transmission method that uses only one channel for transmitting
and receiving, separating them by different time slots. No guard
band is used. This increases spectral efficiency by eliminating the
buffer band, but also increases flexibility in asynchronous applica-
tions. For example, if less traffic travels upstream, the time slice
for that direction can be reduced, and reallocated to downstream
traffic.
