Defi nition
IMEI
The International Mobile Station Equipment Identity [IMEI] number is used to
identify 3GPP [i.e., GSM, UMTS and LTE]. The IMEI number is used by the
GSM network to identify valid devices and has no permanent relation to the
subscriber. The subscriber is identi
fi
ed by transmission of an IMSI number;
stored on the SIM card.
IP Address
An Internet Protocol [IP] address is a 32-bit number [for example, 123.45.67.89
for IP version 4] or a 128-bit number [for IP version 6] that identi
fi
es the network
device that is sending or receiving information that is transmitted across a local
area network [LAN] or the Internet.
LAN
Local Area Network [LAN] is a network that provides data communications
to users within a con
fi
ned geographic area such as a building or complex of
buildings; TCP/IP is the typical transport protocol.
LMS-T
Link Modulation Scheme -Terrestrial
This modulation type has been designed speci
fi
cally to allow the data bandwidth
required for contribution with more ef
fi
cient error correction and more effective
use of spectrum. LMS-T is particularly suited for rapidly changing channels, so it
can be at the higher frequencies 6,7,8 GHz and at higher speeds, where DVB-T
is compromised. LMS-T has been used at 574km/h [356mph] on the French
TGV, while setting the train speed record.
LQ
Link Quality is a feature provided in COFDM receivers that analyzes signal-
to-noise ratio and other important digital signal parameters as supplied by the
COFDM demodulator circuit. The Link Quality feature calculates an integer
value from 0 [no signal] to 9 [highest possible quality].
LTE
Long Term Evolution
LTE is a standard for wireless data communications technology and an evolution
of the GSM/UMTS standards. The goal of LTE was to increase the capacity
and speed of wireless data networks using new DSP [digital signal processing]
techniques and modulations that were developed around the turn of the
millennium. A further goal was the redesign and simpli
fi
cation of the network
architecture to an IP-based system with signi
fi
cantly reduced transfer latency
compared to the 3G architecture. The LTE wireless interface is incompatible
with 2G and 3G networks, so that it must be operated on a separate wireless
spectrum.
MAC Address [BSSID]
The Media Access Control Address
The MAC Address is a unique identi
fi
er assigned to network interfaces, such
as the
NewS
tream
transmitter, for communications on the physical network
segment. A Wi-Fi Access Point’s MAC address is used as the identi
fi
er of
a Basic Service Set [BSSID]. The MAC address of the
NewS
tream
IDU is
also the BSSID for the wireless access point. When prompted,
NewS
tream
’s
connection information retrieval returns the MAC address and BSSID of the Wi-
Fi client, which is displayed in this
fi
eld.
MIMO
Multiple-Input and Multiple-Output
MPEG
Moving Picture Experts Group
A working group of ISO that establishes standards for digital video and audio
compression.
