To be become a LTE Expert?

• Higher data rates (>100 Mbps DL, >50 Mbps UL)
– Increased mean data throughput across the cell
• Reduced latency in data transfer
– Important for VoIP and fast data transfer
• Spectrum flexibility (bandwidth 1.4 to 20 MHz)
– Greater spectrum efficiency than UTRAN
• Efficient Always-on Support
– Rapid transition from Idle to Active mode for Instant
messaging, PoC and Presence services (<100ms)
• User Connections maintained up to 350 km/h

LTE reuses the higher layer functional blocks from the 2G and 3G core networks.
The lower layers provide higher data rates than previously, rates up to 300Mbps downlink and 75Mbps uplink are indicated with the highest class mobile and using multiple antennas at the base station and mobile.
LTE also offers greater efficiency in the use of the available spectrum (3 or 4 times DL and 2 or 3 times better UL). The instantaneous data rate can be changed as the input data rate varies (eg web browsing) or to give the user a specific Quality of Service. Several services may be multiplexed onto a single connection.
Reduced latency (< 5ms one way in user plane) for user data is important for speech circuits but also for data transfer at high speeds on poor channels where repetitions of data are required.
The mobile does still fallback to an Idle mode, but the transition to Active is fast (<100ms) so classed as “Always on”. This is important for instant messaging, push to talk PoC and the Presence services
