Single mode
fiber
A fiber where the light at a specified range of wavelengths only have a single path
through. This is required for analogue modulated systems such as the DeltaNode Fiber-
DAS system
SMA
SubMiniature version A. A Type of RF Connector.
Switch
A network switch is a computer networking device that connects devices together on a
computer network.
TETRA
Terrestrial Trunked Radio. TETRA uses Time Division Multiple Access (TDMA) with four
user channels on one radio carrier and 25 kHz spacing between carriers.
UL
See “Uplink”
UMTS
Universal Mobile Telecommunications System is a system where broadband signaling
and packetized data are used. The standards are handled in the 3GPP group and the
most common type of modulation is WCDMA.
Uplink
The signals that are transmitted from the terminal (phone) towards the base station.
SC-PC
A type of fiber-optic connector which is not angled and should not be used with
DeltaNode Fiber-DAS
SC-UPC
Ultra-polised fiber-optic connector. Not recommended with Deltanode Fiber-DAS
RF
Radio Frequencies, denominates the range of transversal electromagnetic waves with a
frequency from 3 kHz to 300 GHz. The upper end of the spectrum is often referred to as
microwave frequencies.
WCDMA
W-CDMA
Wideband Code Division Multiple Access is a technology employed by base station
manufacturers who make UMTS base stations. This technology is commonly used in 3G
networks and the main modulation employed in Europe.
