WiFi Glossary: Your Connectivity Cheat Sheet

With the growing popularity of Wi-Fi and its ever-changing capabilities, it is important to understand the various terms, acronyms, and standards that are rapidly becoming a part of the lingo. To that end, we’ve put together this glossary of common terms that are used.

Connectivity

ADSL
‘Asymmetric Digital Subscriber Line’ is a type of DSL broadband communications technology used for connecting to the Internet. ADSL allows more data to be sent over existing copper telephone lines (POTS), when compared to traditional modem lines.
Broadband
Any high-speed Internet access that is always on and faster than dial-up access over traditional analogue or ISDN PSTN services
Cable Modem
Hardware device that allows your computer to communicate with an Internet service provider over a landline connection. It converts an analog signal to a digital signal for the purpose of granting access to broadband Internet
Dial Up
Access a computer system or service remotely via a telephone line.
DSL
‘Digital subscriber line’ is the way a computer connects to the Internet at high speeds using telephone lines.

VPN
‘Virtual Private Network’ is programming that creates a safe and encrypted connection over a less secure network, such as the public internet.

Network, Hardware & WiFi

2.4 GHz and 5GHz
5GHz provides faster data rates at a shorter distance and has 23 non-overlapping channels. 2.4GHz offers coverage for further distances, but may perform at slower speeds and nominally only has 3 non-overlapping channels.
Access Point
Device that creates a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a WiFi signal to a designated area.
Boosters
Extends WiFi network coverage space by boosting or amplifying existing signals.
Captive Portal
Web page that the user of a public-access network is obliged to view and interact with before access is granted.
DHCP
Dynamic Host Configuration Protocol (DHCP) is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network.
Ethernet
Traditional technology for connecting wired local area networks (LANs), enabling devices to communicate with each other via a protocol — a set of rules or common network language.

Connects to your network through a wired connection.
Firewall
network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules
IP address
‘Internet Protocol’ is a unique address that identifies a device on the Internet or a local network. It allows a system to be recognized by other systems connected via the Internet protocol. There are two primary types of IP address formats used today — IPv4 and IPv6
IPSEC
‘Internet Protocol Security’ or IP Security protocol, defines the architecture for security services for IP network traffic
LAN

Leased Line
Dedicated uncontended broadband service, meaning it is not shared with other properties in your local area
MAC address
Hardware identification number that uniquely identifies each device on a network.
Mbps
Megabits per second – a unit of measurement for bandwidth and throughput on a network. Each megabit is equal to 1 million bits
MBps
megabytes per second. MB is used in reference to file size, or the amount of data transferred. It takes 8 ‘bits’ of data to equal 1 ‘byte’.
Mesh network
Type of network topology in which a device (node) transmits its own data as well as serves as a
relay for other nodes. Routers are used to provide the best and most efficient data path for effective communication. In the event of a hardware failure, many routes are available to continue the network communication process

PPTP
‘Point-to-Point Tunnelling Protocol’ is a networking standard for connecting to virtual private networks, or VPNs.
QoS
Quality of service is the description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network
Repeater
Electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.
Router
Performs the traffic directing functions on the Internet. Data sent through the internet, such as a
web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.
Unified network
Integrates wired and wireless components, which share network elements and services where feasible, rather than existing as separate multiple networks.
VLAN
‘Virtual LAN’ is a subnetwork that can group together a collection of devices from different physical LANs. Larger business computer networks often set up VLANs to re-partition their network for improved traffic management. Several different kinds of physical networks support virtual LANs, including both Ethernet and WiFi.
WiFi and Wi-Fi
WiFi is a family of radio technologies that are commonly used for the wireless local area networking (WLAN) of devices which is based around the IEEE 802.11 family of standards. Wi Fi is a trademark of the Wi-Fi Alliance,
WLAN
‘Wireless LAN’, a network that allows devices to connect and communicate wirelessly. Unlike a traditional wired LAN, in which devices communicate over Ethernet cables, devices on a WLAN communicate via WiFi
