RMC
Receive Multicoupler. A device for amplifying the input received from a single antenna and providing multiple outputs for a group of receivers.
RSSI
Received Signal Strength Indicator. A measurement of the received RF signal strength measured at the base station or the subscriber terminal. It is expressed in dBm.
SAT
Supervisory Audio Tone. A tone of 5970, 6000, or 6030 Hz which modulates the AMPS voice channel along with voice audio. It is generated by the cell site and is repeated by the mobile back to the cell site. The repeated SAT is checked by the cellular system to confirm the continuity of the complete RF path from the cell site to the subscriber terminal and back to the cell site.
SCC
SAT Color Code. The datafill values corresponding to the various SATs: 00 for 5970 Hz, 01 for 6000 Hz, 10 for 6030 Hz.
Sector
A theoretical
Sectorization
A cell site configuration that consists of two or more sectors in which a different control and voice channel assignment is given for each sector. In this arrangement, the datafill and channel assignments for each sector are tailored to meet the system operational requirements, providing more flexibility in the cell site configuration compared to an omni configuration but with a decrease in trunking efficiency.
Signal (RF)
Radio frequency energy associated with a particular or desired frequency.
SINAD
A standard measurement of detected audio quality that is related to
