K

Kb/s Kilo Bits per Second - 1000 bits/second. A measure of transmission speed. See also bps & Mb/s.

Ku-BandA frequency band used for satellite communications. For terrestrial earth stations the receive frequency band is in the range 10.95 – 12.75GHz and trans- mit 14.0 – 14.5GHz. See also C-band.

L

L-BandA frequency band commonly used as an IF for satellite systems using block up/ down conversion. Usually 950-1450MHz.

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, usually with an L-band (typically 950-1450MHz) 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.
