Mobile devices are changing and are rapidly evolving - mobile phones, laptops, PDAs ……. all with an expectation to roam seamlessly without performance loss over the Wireless LAN.

After several year’s popularity in many sectors, wireless networking has now become embedded in the enterprise as a recognised form of connectivity and flexible way of working. Using an array of devices such as laptops, PDAs and mobile phones, companies have benefited from the productivity gains and cost savings of employees being able to work anyway within the organisation and gain access to information in real time.

Wireless networking offers many advantages to companies but the provision and management of a wireless environment presents its own challenges. Wireless security is critical as a WLAN offers another gateway into the organisation meaning rogue access points and unecrypted traffic can put sensitive data at risk from intruders, unauthorised users or cyber terrorists.

In addition, many mission critical applications are converting to wireless such as CRM, RFID and CCTV, and with new specific mobile applications, all require a resilient Wireless LAN infrastructure over which to run, and a Wireless Security policy to police access.
