Glossary
3G
— Third Generation. 3G refers to the third generation of mobile telephony technology.
4G LTE
— Fourth Generation. 4G LTE refers to the fourth generation of mobile telephony technology.
802.11 (b, g, n)
— A set of WLAN communication standards in the 2.4, 3.6 and 5 GHz frequency bands.
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.
CDMA
— Code Division Multiple Access. It is the underlying channel access method used by some
mobile phone standards.
DHCP
— Dynamic Host Configuration Protocol. Software found in servers and routers that
automatically assigns temporary IP addresses to clients logging into an IP network.
DHCP Server
— A server or service with a server that assigns IP addresses.
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.
Firmware
— A computer program embedded in an electronic device. Firmware usually contains
operating code for the device.
Hotspot
— A WiFi (802.11) access point or the area covered by an access point. Used for connecting
to the Internet.
HTTP
— Hypertext Transfer Protocol. An application-level protocol for accessing the World Wide Web
over the Internet.
IEEE —
Institute of Electrical and Electronics Engineers. An international technical/professional society
that promotes standardization in technical disciplines.
IMEI
— International Mobile Equipment Identity. Used in LTE networks to identify the device. It is
usually printed on the device and can often be retrieved using a USSD code.
IP
— Internet Protocol. The mechanism by which packets are routed between computers on a
network.
IP Type
— The type of service provided over a network.
IP address
— Internet Protocol address. The address of a device attached to an IP network (TCP/IP
network).
ISP
— Internet Service Provider. Also referred to as the service carrier, an ISP provides Internet
connection service. (
See
Network Operator)
Kbps
— Kilobits per second. The rate of data flow.
LAN
— Local Area Network. A type of network that lets a group of computers, all in close proximity
(such as inside an office building), communicate with one another. It does not use common carrier
circuits though it can have gateways or bridges to other public or private networks.

LTE
— Long Term Evolution. A wireless broadband technology designed to support roaming Internet
access via cell phones and handheld devices. Because LTE offers significant improvements over older
cellular communication standards, some refer to it as a 4G (fourth generation) technology along with
WiMax.
MAC Address
— Media Access Control. A number that uniquely identifies each network hardware
device. MAC addresses are 12-digit hexadecimal numbers. This is also known as the physical or
hardware address.
Mbps
— Megabits per second.
MSID
— Mobile Station IDentifier. A number for a mobile phone that identifies that phone to the
network. These numbers are carrier specific.
Network Operator
— The vendor who provides your wireless access. Known by different names in
different regions, some examples are: wireless provider, network provider, and service provider.
Network Technology
— The technology on which a particular network provider’s system is built; such
as CDMA or EVDO.
Port
— A virtual data connection used by programs to exchange data. It is the endpoint in a logical
connection. The port is specified by the port number.
Port Forwarding
— A process that allows remote devices to connect to a specific computer within a
private LAN.
Port Number
A 16-bit number used by the TCP and UDP protocols to direct traffic on a TCP/IP
host. Certain port numbers are standard for common applications.
PRL
— Preferred Roaming List. A list that your wireless phone or device uses to determine which
networks to connect with when you are roaming. (Network operator specific).
Protocol
— A standard that enables connection, communication, and data transfer between
computing endpoints.
Proxy
— A firewall mechanism that replaces the IP address of a host on the internal (protected)
network with its own IP address for all traffic passing through it.
Rev A
— CDMA EV-DO Rev. A is a leading-edge wireless technology with higher data rates and higher
system capacity. It is a fully backward compatible standard and remains interoperable with deployed
EV-DO networks and devices around the world. The increased data rates on Rev. A’s physical layer
enable richer applications and services. For more information, visit

.
Router
— A device that directs traffic from one network to another.
SIM
— Subscriber Identification Module. Found in GSM network technology, the SIM is a card
containing identification information for the subscriber and their account. The SIM card can be moved
to different devices.
SSID
— Service Set IDentifier. The name assigned to a WiFi network.
TCP/IP
— Transmission Control Protocol/Internet Protocol.
The set of communications protocols used
for the Internet and other similar networks.
USB
— Universal Serial Bus. A connection type for computing device peripherals such as a printer,
mobile modem, etc. USB connectors may be used for data transfer or charging.

USB Port Types
— The USB ports on computers and hubs have a rectangular Type A socket, and
peripheral devices have a cable with a Type A plug. Peripherals that do not have an attached cable
have a square Type B socket on the device and a separate cable with a Type A and Type B plug. Ports
and connectors are available in different sizes (for example, standard, mini, and micro).
VPN
— Virtual Private Network. A secure private network that runs over the public Internet.
Commonly used to connect to an office network from elsewhere.
WWAN
— Wireless Wide Area Network. A public network that extends beyond architectural,
geographical, or political boundaries (unlike a LAN, which is usually a private network located within a
room, building, or other limited area).
WEP
— Wired Equivalent Privacy. An IEEE standard security protocol for 802.11 networks. Superseded
by WPA and WPA2.
WiFi
— Wireless Fidelity. Any system that uses the 802.11 standard developed and released in 1997 by
the IEEE.
WiFi Client
— A wireless device that connects to the Internet via WiFi.
WPA/WPA2
— WiFi Protected Access. A security protocol for wireless 802.11 networks from the WiFi
Alliance.
