Term 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 identifi 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 identifi 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 confi 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 specifi cally to allow the data bandwidth
required for contribution with more effi 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 simplifi cation of the network
architecture to an IP-based system with signifi 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 identifi er assigned to network interfaces, such
as the
NewStream transmitter, for communications on the physical network
segment. A Wi-Fi Access Point’s MAC address is used as the identifi er of
a Basic Service Set [BSSID]. The MAC address of the NewStream IDU is
also the BSSID for the wireless access point. When prompted, NewStream’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.
