To get the most out of this arrangement the link needs to be fast and ‘always on.’ There are three cost effective ways of achieving this in the UK, all of which use modern broadband (meaning high speed internet) technology.

The first and simplest option is the home-worker to purchase an ADSL service from BT or an Internet Service Provider (ISP) The ADSL service is delivered to the house over an existing phone line where the signal is then split into voice for the phone and data for the computer. With an ADSL service the customer pays a fixed monthly fee for an ‘always on’ i.e. 24 hours a day internet feed.

The second and still fairly simple option is to connect the home-worker to the internet using a cable modem. Since the large scale installation of cable TV it has been possible to get a fast connection to the internet down the same cable that delivers the TV signal. Cable TV companies tend to offer a combined package of TV, high speed Internet and telephone line to consumers. The cable carries Internet data at speeds similar to an ADSL connection which makes it perfect for home-working.

Wireless Broadband
The third option for connecting the home-worker to the office is over a wireless broadband link. This option is more suited to rural areas where the cable based ADSL service is not available. There a number of companies offering this service across the country and although slightly more expensive it is proving very effective and popular. The provider places wireless access points in the local area and then a small antenna is placed on the outside wall of the house and aligned to the nearest access point. The radio signal then carries the internet service to and from the home-worker’s PC.

Office Internet Connection
For home-working to be viable the company office must be connected to the internet via an 'always on' high bandwidth connection. A leased line is preferred but a business grade ADSL link is also possible. If a leased line connection is in use it is most likely that you will be using a firewall to protect your data and this equipment can often be configured to handle in-coming secure connections.

Virtual Private Networks
The term for describing the secure channel set up between the home user and the office network is called a Virtual Private Network or VPN. The effect of creating a VPN is to scramble the information passing between the office and the home-user over VPN and then de-scramble it at the point of use. This process is called encryption and it keeps your corporate data safe from hackers and others. VPN's can be created by hardware, software or a combination of both depending on the level of security and convenience that is required.
