Mobile phone glossary

A glossary of terms to help you understand mobile phones

What is 3G? How does a cap plan work? We'll answer all of these mobile phone questions for you.

2G: 2G is a second-generation mobile phone network.

3G: 3G is a third-generation mobile phone network that supports higher data capacities, enabling features such as mobile Internet access. A 3G network is also capable of video calling.

Bluetooth: Bluetooth is a wireless technology that provides a way to connect and exchange data between mobile phones and other devices.

Capped plan: A capped plan is a monthly contract where you only pay a certain amount per month if your usage doesn't exceed a maximum value.

GSM: Global System for Mobile communications. GSM is the most popular standard for mobile phones in the world.

HSDPA: High-Speed Downlink Packet Access. HSDPA is a 3G mobile protocol that offers higher data capacity and transfer speeds. This means that more information -- such as video -- can be transferred wirelessly to your phone at faster speeds.

Infrared: Infrared (IrDa) is a short-range wireless technology that provides a way to connect and exchange data between mobile phones. It has largely been succeeded by Bluetooth.

MMS: Multimedia Messaging Service. MMS is the sending of messages that include multimedia such as images, audio, video and text.

Pre-paid: Pre-paid is a mobile phone account where credit for phone calls is paid up front, and not billed by the month.

Push e-mail: When new e-mail is sent to you, it is instantly transferred (or “pushed”) to a mobile phone handset.

SIM card: Subscriber Identity Module card. A SIM card is a removable “smartcard” that is inserted into a mobile phone. SIM cards store the service provider details and identify the customer to the mobile network. You need a SIM to connect to a mobile phone network and make calls.

Smartphone: A smartphone is a mobile phone with computer-like features that can include e-mail, an Internet browser, a personal organiser, a touch screen or a keyboard.

SMS: Short Message Service. SMS is the sending of short (160 characters or less) text messages, to and from mobile phones. Receiving SMS messages is free of charge, but sending them costs 25 cents across all networks in Australia. Some networks may offer discounted rates for SMS messages sent across their own network.

WAP: Wireless Application Protocol. WAP is an Internet-like service for a mobile phone. WAP is not the same as using a browser on a computer.

Wi-Fi: Wi-Fi stands for Wireless Fidelity and is a wireless technology that allows connection to the Internet when in range of an “access point”. It is normally associated with accessing the Internet from a computer, but many mobile phones -- particularly business smartphones -- have Wi-Fi as a feature.

I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
