J Plus, Inc 1 Introduction 1.1 Overview JLT733A is Pico LTE small cell. LTE small cell is a wireless network system based on 3GPP LTE (Long Term Evolution) technology; LTE small cell improves 3G technology’s shortcomings of relatively slow transmission speed with high cost. This new generation wireless network system provides high speed data throughput with relatively economic cost using the existing Internet line or low cost backhaul. 1.
J Plus, Inc 1.4 Network Block Diagram Pico LTE small cell, JLT733A, provides wireless access to LTE UE, and it is connected to MME (Mobility Management Entity) for control plane signaling via S1-MME logical interface. For the user data service, JLT733A is connected to S-GW (Serving-Gateway) via S1-U logical interface. Connection between EPC and LTE small cells may go through HeNB-GW instead of directly getting connected to EPC.
J Plus, Inc 2 System Features The JLT733A is Pico Base Station which supports a wide range of LTE interfaces. It provides an ideal costeffective alternative to macro deployments for coverage and capacity needs, suitable for vertical market business including smart grid network and services at railways, campuses, mines, oil drilling sites, bay area, and harbors. 2.1 JLT733A System Main Functions 2.1.1 3GPP Standards JLT733A supports 3GPP Release 10 and complies with following specifications.
