wifiSometimes known as Wi-Fi or 802.11 networks, they let computers talk to one another using a radio link similar to cordless phones.
The problem is that most wireless network equipment, when it comes out of the box, is not protected against the threats below in order to make it easy to set up. This means you have to configure the network yourself to make it secure. The following are some potential threats to a wireless network not installed correctly:

Eavesdropping Listening to the information as it is transmitted over the air. To protect from this information on the network must be encrypted.
Hacking Anyone in range can connect to the network. The network must be restricted to known and trusted users and computers.
Freeloading Where a wireless network is used to share a broadband internet connection, there is a risk that unauthorized users will use your connection without permission.

Our engineers have set up wireless networks in a wide range of locations and understand the importance of security without losing site of performance.
