Gaiacomm International Terahertz repeaters, are designed to provide indoor
and outdoor coverage in a wide variety of environments.
The Gaiacomm International Terahertz repeaters are true repeaters offering signal down
conversion to an IF (intermediate frequency). Repeaters are more effective than
BDAs because at this low IF, highly selective bandpass filtering effectively
rejects adjacent band competitors and interfering signals. Then, the signals are
up converted back to their original frequencies, amplified, and radiated via the Base Station server antenna.
Most other units in the competitor category are simply bidirectional
amplifiers (BDAs) that offer little or no band pass filtering. These
units will amplify and re-transmit competitor’s signals, using valuable RF power
that could be used to amplify the desired in-band signals.
Many people install inexpensive BDAs, and quickly find out that the coverage
area and overall signal levels are less than what they expected. This is because so
many other undesired signals are consuming the RF power in the BDA so that
little is left for in-band signals. A repeater will transmit only the desired signals,
so no RF is wasted. Also, a repeater is frequently competitively priced relative to
a BDA, especially if external bandpass filters must be added to the BDA to make
it rejects out-of-band signals.
