Term Stands For.... Meaning
RF Radio Frequency A portion of the electromagnetic spectrum in the frequency
range between audio and infrared: 100 KHz to 20 GHz. RF
measurements are expressed in Hz (unit for measuring
frequency); MHz = 1 Million Hz; GHz = 1 Billing Hz.
RFS Radio Frequency Subsystem A term for the antenna portion of the base station.
RH Relative Humidity The amount of water vapor in the air, given as the percent of
saturation humidity, generally calculated in relation to saturated
vapor density.
RMS Root mean Square The most common mathematical method of defining the effective
voltage or current of an AC wave
RS Reed-Solomon Reed-Solomon codes are block-based error correcting codes with
a wide range of applications in digital communications.
RSSI Receiver Signal Strength Indicator A term that describes the measure of the signal strength in
kilohertz or gigahertz between the transmission and the receiving
end.
Rx Receive An abbreviated way of expressing the term, receive, as in to
receive a transmission.
S-CDMA Synchronous Code Division
Multiple Access
Wireless technology based on data being transferred at a fixed
rate using Code Division Multiple Access algorithms.
SELV Safety Extra Low Voltage A secondary circuit which is designed and protected in such a
way that, under normal operative conditions or under a single
fault condition, its voltage does not exceed a safe value.
SLIP Serial Line Internet Protocol A TCP/IP protocol used for communication between two
machines that are previously configured for communication with
each other.
SMDS Switched Multi-megabit Data
Service
Connectionless service for MAN/WAN based on 53-
byte packets
that target the interconnection of different LANs into a public
switched network at speeds higher than T1.
SMS
1
Short Message Service or
2
Systems Management Server
1
A protocol that allows mobile users to send text-
based messages
from one devi
ce to another. The text appears on a device’s screen
and may be a maximum 160 characters in length.
2
A Windows
NT process that allows a network administrator to inventory all
hardware and software on the network, then perform software
distribution over the LAN.
SNMP Simple Network Management
Protocol
Standard management request-reply protocol for managing
TCP/IP networks. A device is said to be SNMP compatible if it
can be monitored or controlled using SNMP messages.
SNR Signal-to-noise Ratio Related to RSSI, a measurement of the intended signal being
transmitted against the other entities that can interfere with the
signal.
SO/HO Small Office/Home Office Small, remote office with a MAN or WAN connection back to a
larger corporate network and/or the Internet.
SoW Statement of Work A document outlining the general activities that must be
conducted in order to complete the installation and
commissioning tasks for a Ripwave Base Station
SSI Signal Strength Indicator See “RSSI”.
SW Software Computer instructions or data.
SYN Synthesizer Card A circuit card in the Navini BTS digital shelf that provides a
local oscillator and system clock with a single calibration
transceiver. The card is used to calibrate the Base Station so that
no external spectrum analyzer or signal generator is required.
SYNCH Synchronous Digital packets or signals that are sent at the same, precisely
clocked fixed rate of speed.
