Glossary
• 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
processing) 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
LTE 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 providers, competing with other ISPs. 5G also opens up new IoT and M2M
possibilities. 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 — Access Point Name. The name of a gateway between a mobile network and another
computer network, often the Internet.
• 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 channels can carry video, voice, and data simultaneously.
• CHAP — Challenge Handshake Authentication Protocol. Protocol used in conjunction with
Point to Point Protocol (PPP) to provide security and authentication to users of remote
resources. CHAP does not use username/password, but uses a challenge method for
authentication. Initiator sends a logon request to the server. The server sends back a challenge
to the client. The challenge is encrypted and sent back to the server. The server compares the
value from the client, and if it matches, allows the session. If the compare fails, the session is
denied and the request restarts.
• DHCP — Dynamic Host Configuration Protocol. Software found in servers and routers that
automatically assigns IP addresses and other configuration data to computers, tablets, printers,
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 converting host names and domain names into IP
addresses on the Internet or on local networks that use the TCP/IP protocol.
