Appendix I - Glossary I-5
K
Kb/s Kilo bits per second – 1000 bits/second. A measure of transmission speed. See
also bps & Mb/s.
Ku-Band A frequency band used for satellite communications. For terrestrial earth
stations the receive frequency band is in the range 10.95–12.75 GHz and the
transmit frequency band is 14.0–14.5 GHz. See also C-band.
L
L-Band A frequency band commonly used as an IF for satellite systems using block up/
down conversion. Usually 950–1450 MHz.
LAN Local Area Network
LLA Low Latency Application
LNA Low Noise Amplifier – An amplifier with very low noise temperature used as
the first amplifier in the receive chain of a satellite system.
LNB Low Noise Block – A downconvertor so called because it converts a whole
band or “block” of frequencies to a lower band. It is similar to LNA.
LNC Low Noise Converter – A combined low noise amplifier and block down
converter, typically with an L-band IF.
LO Local Oscillator
M
M&C Monitor & Control
MAC Media Access Control – A protocol controlling access to the physical layer of
an Ethernet network.
Mb/s Mega Bits per Second – 1 Million bits/second. A measure of transmission
speed. See also bps & kb/s.
Modem MODulator and DEModulator units combined.
Multicast Transmitting a single message simultaneously to all recipients.
