An APN can be used as a primary link to connect devices that are based in remote locations where other connectivity options (ADSL, leased lines) are not available. It can also be used as a secondary link (failover).
APN’s are becoming widely deployed in businesses throughout South Africa and the rest of the globe. They have found their place across various business platforms including corporates, telemetry applications and point-of sale networking. They provide Inter-branch GSM connectivity for business of all size, backup of traditional leased & ADSL lines and various other platforms.
From cost benefits to ease of deployment, APNs provide a fast, secure alternative for business in the arena of wide-area connectivity.
As the communication protocol (3G, edge) is provided on the mobile operators network, redundancy is provided via the cellular provider, lowering cost to client tremendously.
The APN service can either function with standard contract SIM cards or via a cheaper data bundle deployed across multiple SIM cards.
Every cellular network provider offers a public APN which allows users to connect via a SIM card. A public APN allows full access to all subscribers. In other words a public network allows all subscribers access to the Internet by default. When a subscriber connects to the internet via your smartphone, tablet or 3G laptop, a connection is made to the public APN of your cellular provider. When a SIM card is provisioned for data use, the public APN of the provider is added by default (eg: APN Vodacom). As the name suggests, this APN is open to general subscribers.
A private APN is effectively a private cellular network which as acts a gateway to a company private (LAN). Private APN’s are built on top of a public GSM networks. Although a private APN makes use of the basic infrastructure offered by cellular providers, it runs independently of public networks, with it’s own set of communication rules and protocols. A private APN is highly customizable to suit customer requirements including: type of network connection, allowed IP addresses and security methods to be used.
A variant of a private APN, a corporate APN is a business connectivity solution providing secure, private and customized remote access to your company LAN through a GSM network. Corporate APN’s bypass public cellular networks and offers the client a private cellular network to allow remote employees to access their company’s private network with total security. This increases productivity & efficiency by enabling employees to remotely access corporate emails, documents and business applications, thus eliminating the need to be in the office. Employee’s use a SIM card which has been authenticated (allowed) on your APN, to gain access to your company’s private LAN. Once a connection has been established, the GSM device is able to exchange data with the customer’s private network. Two tiers of security are provided:
