Home Location Register is a database that contains data regarding authorized subscribers using a global system for mobile communication core network.

Full Duplex (FDX) is a type of communication system. In full duplex, there is a two-way communication between the sender and the receiver.

High speed downlink packet access (HSDPA), also known as 3.5G is an improved third generation telecommunication protocol.

The visitor location register (VLR) is a database which houses information about the subscribers whom have roamed within a mobile switching center’s (MSC) location area.

Half Duplex (HDX) is a type of communication system. In half duplex, there is a two-way communication between the sender and the receiver.

5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks.

An Embedded-SIM (eSIM) or embedded Universal Integrated Circuit Card (eUICC) is a rewritable Subscriber Identifier Module (SIM) card that is embedded directly in to an IoT device

A firewall is a network security system that prevents unauthorized users from having access to a network.

4G is the fourth generation of broadband cellular network technology, succeeding 3G. 4G works much in the same way as 3G, but simply faster.

A Base Station controller (BSC) is a telecommunication network component responsible for the control of one or more Base Transceiver Stations (BTS).

A base station is a radio receiver which may have one or multiple antenna. It was first used in mobile telecommunication networks.

Bandwidth is the maximum amount of data that can be transmitted over a network path in a fixed amount of time.

Backhaul in terms of telecommunication refers to the physical part of a network that is in between the backbone of the network and the individual local networks.

Code division multiple access (CDMA) is a multiple access scheme that relies on direct sequence spread spectrum communication techniques to facilitate radio communication.

Cellular Network also referred to as a mobile network is a network of radios distributed over land. These networks are distributed by cells.

A cell is a geographical area covered by the frequency emitted by a base station in a cellular network. The elements that transmit this frequency is called a cell site.

Dynamic Host Configuration Protocol (DHCP) is a network management protocol that provides a framework that allows the allocation of internet protocol (IP) addresses.

Ethernet is the most common type of Local Area Network (LAN) Connection in use today. Ethernet connects devices on a wired LAN, enabling them to communicate with each other using a common protocol.

Encryption is the method of encoding information. The process of encrypting and decrypting information is known as cryptography.

Frequency is defined as the number of cycles per unit time. Frequency is usually used to represent short and fast waves like sound and radio signals.
