� Spectrum flexibility:– Use of new, re-farmed or unused spectrum– FDD and TDD– Variable channel bandwidth
� Performance:– Higher peak rates– Higher bandwidth– Designed for ”always on applications” from start
� Cost:– IP-based flat Network Architecture
(no circuit switched domain)– Low OPEX– Simpler operation with less to configure and higher degree
of self configuration
Driving forces behind LTE
