about LTE

1. Basic & RF Tuning Training

2. LTE ADVANCED (4.5G) REFRESHMENT : MIMO 4x4 Transmit Diversity Spatial Multiplex Beamforming Carrier Aggregation Carrier Aggregation Concept Type of CA and Component Carrier CA and Protocol Layer CA Activation LTE (ADVANCED) REFRESHMENT

3. MIMO Technology

4. Transmit Diversity : - To improve radio Quality by it’s Transmit Diversity or Receiver Diversity antenna capability Spatial Multiplex - User’s Data can be transmitted in different stream or layer that can increase data rate MIMO Technology

5. MIMO – UE Feedback (RI, CQI, TM) and Antenna Port

6. MIMO – Beamforming Antenna Element Solution for Active Antenna with radio Integrated (AIR) Unit is named “AAS”(Advanced Antenna System). Beamforming is achieved when the same signal is sent to different (correlated) elements of the antenna with well defined phases and amplitudes. AIR 1641 Deployment (MIMO 16x16 ) Passive vs Active Antenna MIMO 4x4 Passive vs Active Antenna MIMO 8x8

7. LTE Carrier Aggregation

8. LTE Carrier Aggregation Transmit user’s data using more than one carrier in Downlink , but possible also to do the same in Uplink. Carrier Aggregation Types CA Basic Concept

9. LTE Carrier Aggregation and Protocol Stack CA Component Carrier LTE Maximum Component Carrier Carrier Aggregation in MAC Layer Carrier Aggregation is used to multiplex the components carrier data on MAC layer (LTE Protocol Stacked Layer 1/2)
