However, it's worth looking just at the associated capital, installation & support costs. The installation of a wireless solution has shown to provide up to 88% cost savings on capital & support costs, the cost of moves/additions/changes is virtually eliminated with an all wireless edge as the network seamlessly supports users who are presumed to be moving continuously.
INCREASED SECURITY WLANs are now protected with very strong authentication & encryption technology & they are able to identify & apply security policies based on who the user is, what type of device it is, how it is authenticating, when & where it is connecting & more. Some mobility controllers also integrate policy enforcement firewalls, enabling them to implement role-based access control, tying users to policies & roles defined in directory services.
CONVERGENCE & VOICE MOBILITY Mobile workers need to take their computers with them as they move about, which requires that their phone is "mobilised" as well. Voice over WiFi-VoFi implementations can deliver both internal phone system functionality & user mobility.
GREATER RESILIENCE & MANAGEABILITY Today's WLANs are usually built using a centralised architecture comprising a mobility controller & thin access points. Thin APs simply provide WiFi access & monitor the air for intrusion; all the intelligence & security is offloaded to the mobility controller. The entire WLAN can be managed from a single mobility controller & conseqtently WLANs with numerous controllers & thousands of APs can be managed with a small staff.
MOBILITY & INCREASED PRODUCTIVITY Finally & most significantly, an all-wireless edge enables mobility. This applies not only within the walls of a single building or across a campus, but extends to branch offices, workers' home & other locations across the WAN & the Internet. Users are provided with a consistent experience & secure access to voice & data resources.
