The Applications 
The mobile edge is an enabling technology for new applications that can deliver increased productivity, cost savings, security improvements, and faster access to information that ultimately leads to better decision making. The mobile edge enables several major applications in the areas of mobility, security, and convergence.
Mobility
Guest Access Provides controlled Internet access, both wired and wireless, to authorized visitors while keeping the internal network secure.
Internal WLAN Hotspots Wireless LAN access for employee and visitor convenience in strategic locations such as conference rooms, lobbies, cafeterias, and auditoriums.
Enterprise-wide WLAN Pervasive, highly-available, high-performance wireless LAN access throughout an entire enterprise building, campus, or extended enterprise.
Remote/Branch Office Access Secure extensions of the mobile edge to remote and branch offices using the Internet or enterprise WAN as transport.
Small Office, Home Office, and Road Warrior Access Extends the mobile edge anywhere a user travels through portable, personal remote access points.
Secure Mobility for Legacy WLANs Extends the life of existing wireless LAN deployments through enhanced security, roaming, and management.
Location Tracking Uses an enterprise-wide WLAN deployment to provide precise location tracking of any Wi-Fi device in the facility.
Security
Identity-based Security Enhances security by identifying the business role of the user and then allowing only network access appropriate to that role.
WLAN Intrusion Prevention Prevents radio-based security breaches by identifying threats to the network from attackers and uncontrolled wireless devices.
Endpoint Integrity Ensures a defined level of client security, such as anti-virus, anti-spyware, or personal firewall software is present before network access is granted.
External Security Services Integrates best-of-breed security appliances, such as anti-virus, content filtering, and IDS as interior network services that are client-independent.
L2 Security for Wired LANs Delivers mobile edge solutions such as encryption, mobility, and identity-based security to legacy wired LANs.
Convergence
Telephony Solutions Provides the cost advantages of Voice over IP with the mobility benefits of cellular voice.
Voice Instant Messaging Enables hands-free voice communication through an innovative new class of voice instant messaging devices, enhanced with proximity sensing.
Converged Mobile Devices Delivers quality of service and access control to unified communications messaging devices integrating multi-media services such as voice, data, email, and fax.
Fixed-Mobile Convergence Unifies public and private voice networks by providing seamless handoffs between networks for dual-mode cellular/Wi-Fi voice devices.
