Seamless integration of Wi-Fi and LTE is important for offloading data traffic from cellular networks to Wi-Fi networks, which can help improve network capacity and performance.
LTE: Changing the Face of NewsgatheringPraveen Kumar
Richard Pattison discusses how LTE technology is revolutionizing Sky News' newsgathering capabilities. Previously reliant on expensive satellite trucks, Sky News can now use smaller, cheaper cellular bonding devices and smartphones to transmit live video over 4G networks. Key developments include testing early 4G networks in 2012-2013, securing large data plans from mobile providers, and deploying Aviwest cellular bonding devices which provide stable, high quality live streams. Sky News now has 24 cellular devices matching the number of satellite trucks, demonstrating how LTE has transformed their newsgathering abilities.
The document discusses network sharing opportunities in LTE mobile networks. It describes how network sharing can help reduce costs for mobile service providers facing increasing data traffic and changing revenue models. The standards allow for two types of network sharing - national roaming, where one operator's customers access another's network, and eUTRAN sharing, where operators share active network elements like base stations. eUTRAN sharing has two approaches defined in 3GPP - Multi-Operator Core Network (MOCN), where the shared network connects to separate core networks, and Gateway Core Network (GWCN), where the shared MME is also shared. Customer cases illustrate how different sharing models may apply depending on the market situation and operators' objectives.
Difference in Rrc procedures lte and 3GPraveen Kumar
- RRC in LTE has only two states - RRC_IDLE and RRC_CONNECTED, compared to five states in 3G. This simplifies RRC state handling and RRM algorithms.
- Signaling radio bearers are simplified to SRB0, SRB1, and SRB2 (still being finalized) compared to four SRBs in 3G.
- RRC procedures and messages are simplified in LTE compared to 3G. This reduces signaling overhead and complexity.

Mimo and smart antennas july 2013 finalPraveen Kumar
The document discusses MIMO techniques and antenna configurations used in LTE networks. It describes how LTE supports 1-8 transmit antennas at the base station and 2-8 receive antennas at the UE. The most common configuration is 4x2 MIMO where the base station uses 4 transmit antennas and the UE uses 2 receive antennas. MIMO can increase peak data rates through spatial multiplexing but works best for users with high SINR close to the base station. Open loop MIMO is used for high mobility while closed loop MIMO relies on channel feedback for better performance but only works well in low mobility environments.
