 4G LTE —Fourth Generation Long Term Evolution. LTE is a standard for wireless data
communications
technology and an evolution of the GSM/UMTS standards. The goal of LTE is to
increase the capacity and speed of wireless data networks using
new DSP (digital signal
proces
sing) techniques and modulations that were developed around the turn of the
millennium. A further goal is the redesign and simplification of the network architecture to an IP-
based system with significantly reduced transfer latency compared to the 3G architecture.
The
L
TE wireless interface is incompatible with 2G and 3G networks,
so that it must be operated on a
separate wireless
spectrum
 5G—Fifth Generation. The successor to 4GLTE technology,
offering greater bandwidth and
higher download
speeds. In addition to serving cellular networks, 5G networks can be used
as
internet service provider
s, competing with other ISPs. 5G also open
s up new IoT and M2M
po
ssibilities. Wireless devices must be 5G enabled to use 5G networks.
 802.11 (a, b, g, n, ax) — A set of WLAN Wi-Fi communication standards in the 2.4 and 5 GHz
frequency bands.
 APN — Acce
ss Point Name. The name of a gateway between a mo
bile network and another
computer network, often the In
ternet.
 bps — Bits per second. The rate of data flow.
 Broadband — High-capacity high-speed transmission channel with a wider
bandwidth than
conventional modem lines. Broadband c
hannels can carry video, voice, and data simultaneously.
 DHCP — Dynamic Host Configuration Protocol. Software found in
servers and routers that
automatical
ly assigns IP addresses and other configuration data to computers, tablets, prin
ters,
and other devices connection to the IP network.
 DHCP
Server — A server or service with a server that assigns IP addresses.
 DMZ — DeMilitarized Zone. A sub-network that contains and exposes an organization's
external-facing services to an untrusted network, usually a larger network such as the Internet.
 DNS — Domain Name System. A system for converti
ng host names and domain names into IP
addre
sses on the Internet or on local networks that use the TCP/IP prot
ocol.
 Firmware —
A computer program embedded in an
electronic device. Firmware usually
contains operating code for the device.
 FT
P — File Transfer Protocol. A standard network protocol used to transfer co
mputer files
between a client and server.
 GB — Gigabyte. A multiple of the unit byte for digita
l information storage. Usage depends on
context. When referring to disk capacities it usually means 10
9
bytes. It also applies to data
transmissi
on quantities over telecommunication circuits.
