Frequently Asked Questions

What is M2M?

M2M is an acronym for Machine to Machine. From the name, proactive human involvement is seldom part of the one or two-way communication process.

The idea behind the technology is to streamline the way data is collected from physical devices and incorporated into IT systems without having to rely on people to intervene within the process.

What is a SIM?

A Subscriber Identity Module (SIM) on a removable SIM Card securely stores the service-subscriber key (IMSI)

used to identify a subscriber on mobile telephony devices (such as computers) and mobile phones.

What is an IP Address?

Every machine on the Internet has a unique identifying number, called an IP Address. A typical IP address looks like this:

To make it easier to remember, IP addresses are normally expressed in decimal format as a 'dotted decimal number' as illustrated above.

What is a Public IP Address?

Public IP addresses are IP addresses that are visible to the public.

Because these IP addresses are public, they allow other people to know about and access the device, like a Web server.

What is a Private IP Address?

An IP address is considered private if the IP number falls within one of the IP address ranges reserved for private uses by Internet standards groups. These private IP address ranges exist through the following ranges: through through (APIPA only) through through

What is a dynamic IP Address?

This in simple terms is the opposite of a fixed IP address. When a machine connects to the network, an IP address is assigned to it. However, when the machine disconnects, it loses the IP address.

The next time the machine connects, it will pick up a new IP address.

What is GPRS?

GPRS stands for General Packet Radio Service. It is a wireless technology used by GSM (Global System for Mobile) networks which enables Internet and other data communication.

Because it is packet-based, you can stay online for an unlimited amount of time as only downloaded data is monitored with this service.

What is 3G?

3G stands for third generation, a generic wireless industry term for high-speed mobile data delivery over mobileular networks. 3G networks allow users to send and receive bandwidth-intensive information such as video, video conferencing, high quality audio and web data on-demand, virtually anytime and anywhere.

What is 4G?

4G is a communications standard intended to replace 3G, allowing wireless Internet access at a much higher speed.


High-Speed Downlink Packet Access (HSDPA) is a new mobile telephony protocol and is sometimes referred to as a 3.5G (or 3½G) technology. HSDPA provides a smooth evolutionary path for Universal Mobile Telecommunications System (UMTS) networks allowing for higher data capacity (up to 14.4 Mbit/s per cell in the downlink and 2 Mbit/s in the uplink per cell).

High-Speed Uplink Packet Access (HSUPA) is a 3G mobile telephony protocol in the HSPA family with up-link speeds up to 5.76 Mbit/s.

What is GSM?

Global System for Mobile communications, the second generation digital technology originally developed for Europe but which now has in excess of 71 per cent of the world market.

Initially developed for operation in the 900MHz band and subsequently modified for the 850, 1800 and 1900MHz bands. GSM originally stood for Groupe Speciale Mobile, the CEPT committee which began the GSM standardisation process.

What is HLR?

HLR stands for 'Home Location Register', and is the network database that holds details of every customer SIM card. When a customer wants to access a service, the network checks the HLR to see whether the customer is authorised to do so.

It also keeps track of customers' locations so incoming calls and SMS' can be connected.
