SD-WAN is a relatively new wide-area network (WAN) solution, which uses software virtualisation to provide multi-site connectivity, similar to Multiprotocol Label Switching (MPLS) while merging multiple services into a single hardware appliance.
SD-WAN can be thought of as a ‘successor’ to virtual private networks (VPN), in that it is a software-based solution natively providing Internet Protocol Security (IPSec) standard security. However, while a standard VPN can only exist between two specified points, SD-WAN can connect any number of sites through a virtual network over the open internet.
SD-WAN includes a number of additional features, such as security, Quality of Service (QoS), local area network (LAN) and WiFi, removing the need for separate devices.
Find out about the things you need to consider when setting up a WiFi network for your business.
Where a decade or so ago business computing would have largely revolved around the desktop, in recent years there’s been a major shift towards the use of mobile devices. There’s greater emphasis on smartphones and tablets in the workplace and many companies have implemented bring-your-own-device (BYOD) policies, allowing staff to use their own personal devices to complete work tasks.
In setting up a WiFi network for your business, there are a number of things you need to consider. How many people will be using it? What sort of area does it need to cover? Do you need to provide guest access for contractors and other visitors? Do you plan on offering a public hotspot for casual visitors to your business?
When it comes to coverage, it’s important to consider the layout of the office space. Open plan spaces are easiest as there’s nothing to obstruct the signal, although you may need a number of access points to ensure even coverage over a large area. If your building is divided into smaller spaces, then brick or breeze block walls are likely to obstruct the WiFi signal far more than lighter partition walls and again, this may mean the need for more access points in order to get even signal coverage.
