This paper will outline how mobile operators can prepare their networks to support 4G broadband services that will improve the user experience and yield new revenue opportunities. Specifically, we will discuss how Cisco can assist UMTS operators in their move toward Long Term Evolution (LTE), a 3rd Generation Partnership Project (3GPP) standard that represents a significant advancement in mobile technology.

With industry-leading mobile infrastructure solutions from Cisco operators can:

• Gradually transition from 2G/3G to 4G without a comprehensive network upgrade
• Support 2G/3G and 4G functionality on a single platform
• Meet LTE requirements for increased data rate capacity, reduced latency, and improved spectral efficiency
• Provide transparent roaming between High Speed Packet Access (HSPA) network and LTE network
• Take a phased approach to migrating the HSPA network to LTE by upgrading the core network to Evolved Packet Core (EPC) elements without an overlay Radio Access Network (RAN)
