Here are some of the frequently asked questions received by Wireless Logic – it’s not an exhaustive list, but it is designed to address many of the areas often raised by customers and partners.
M2M is an acronym for Machine to Machine. As the name describes, 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.
A Subscriber Identity Module (SIM) on a removable SIM Card securely stores the service-subscriber key (IMSI)
Access Point Name or APN is the name of an access point for GPRS/3G/HSDPA/HSUPA.
- An Internet network to which a mobile can be connected
- A set of settings which are used for that connection
- A particular option in a set of settings in a mobile phone
A Private APN gives a customer direct access to their LAN and allows them to specify certain parameters such as the private address space allocated to the devices & RADIUS server attributes for user authentication.
The benefit is that the traffic is secure and never goes on to a public network, staying completely on GPRS/3G. This lessens complexity in the communications path and is one less point of failure in the system.
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.
Public IP addresses are IP addresses that are visible to the public.
Every network provider has a public APN. When the SIM card is enabled for data e.g. GPRS/3G etc the public APN is added by default.
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:
10.0.0.0 through 10.255.255.255
169.254.0.0 through 169.254.255.255 (APIPA only)
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255
A fixed IP address is sometimes known as a static IP address. It is an address that is assigned to a computer by an Internet service provider (ISP) to be its permanent address on the Internet.
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.
With a fixed Public IP address, you can connect to your device from any machine anywhere. You do not need to set up a VPN tunnel. This is an ideal solution for customers who do not have a firewall or do not require to set up a VPN tunnel of some type. However, as it is a public IP address, the device is open for anyone to connect to if they know the IP address.
The IP address for the device is ‘hidden’. As a result the device cannot be accessed from any machine anywhere unless there is a secure VPN tunnel set up between the device and the machine.
A VPN is a private network that uses a public network (usually the Internet) to connect to devices with Private IP addresses from a machine on your LAN or from home. Instead of using a dedicated, real-world connection such as leased line, a VPN uses ‘virtual’ connections routed through the Internet from the company’s private network to the remote device.
A site-to-site VPN tunnel is where two firewalls are used to create a VPN tunnel. At Wireless Logic, we use IPSEC VPN tunnels. We configure a firewall on our side and then send the config parameters to the customer. The customer would then needs to enter the config parameters onto their firewall/router.
For those customers who require a Private IP address but do not have a hardware firewall/router, they can download our Sonicwall NetExtender VPN client. We would set up the customer with a username and password. the customer would then enter that when to start up the VPN client.
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.
3G stands for third generation, a generic wireless industry term for high-speed mobile data delivery over mobile 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.
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).
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.
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.
Is a number uniquely identifying a subscription in a GSM or a UMTS mobile network. Simply put, it is the telephone number to the SIM card in a mobile/cellular phone.
4G is the mobile phone network using the Internet with speeds five times faster than 3G. It is suited to more volume data applications.
SIMPro is the engine behind a user’s complete visibility, control, billing and management of SIM estates, regardless of mobile network. Designed to view the activity of large SIM estates, SIMPro is integrated within every all customers’ managed services packages when combined with SIM subscriptions.
As part of the SIMPro platform BillPro empowers users to manage their billing administration in line with their own systems and procedures. Users can view their latest invoices instantly, download usage reports at the click of a button, view GPRS, SMS and CSD usage in monetary value, search and sort high data SIMs by username or CTN as well as drill down data usage by time, date, duration and bytes.
In the latest version of our SIMPro platform, we have introduced the concept of a ‘Customer Solution’; which is an activation profile. This solution contains all of the details needed to activate the SIM to the customer unique configuration.
