1 Introduction
1.1Overview
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.
1.2Type of Small Cell
LTE small cell has a core similarity with WiFi technology where both system provide wireless traffic in
residentials and hotspots as inFigure 1. Difference is that WiFi uses ISM band while LTE small cell uses
commercial frequency band operating within the commercial LTE network.Generally, small cell can easily be
installed like WiFi AP while Picocell is recommended to be installed after cell planning by wireless operators.
Figure 1: Types of Small Cell
1.3Benefits
To satisfy the customer needs, LTE system must provide fast packet transmission with low cost to support high
speed multimedia data service. With LTE small cell deployment, existing public Internet network can be shared
wirelessly, thus it can offload the data traffic as Wi-Fi does. It can also provide the coverage extension effect
with providing LTE service inside the buildings. The high efficiency with low cost makes the LTE small cell
attractive to wireless operator to create new business model. Therefore, it brings better service experience to
their customers.

1.4Network 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. S-GW is connected to
P-GW (PDN-Gateway) for external network access including Internet service.
JLT733A supports IPSec with Security-GW when it is deployed in public network. It carries out either USIM-
based or Certificate-based authentication procedure for creating IPSec tunnel to Security-GW located in front of
HeNB-GW. Security-GW may co-locate with HeNB-GW. In addition, it has been proved in the field to work
seamlessly with our cutting-edge management system HeMS and SON server for plug and play-based
configuration including automatic parameter setting, alarm reporting, statistics gathering and interference
mitigation.

2 System Features
The JLT733A is Pico Base Station which supports a wide range of LTE interfaces. It provides an ideal cost-
effective 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.

RF signal from transceiver enters Power AMP module through BALUN and a Filter. In Power AMP module,
the signal is generated as the maximum level and this signal is transmitted via ANT after passing Filter (out
of band’s noise removal)
B. Uplink (Rx)
The RF signal from ANT enters filter (out of band’s noise removal) and then enters Power AMP module.
This signal is amplified via LNA and then enters Transceiver via a Filter and BALUN.

2.8Digital block Description
JLT733A is equipped with 4Giga Byte DDR3 SDRAM and CPU(Intel/T3300) operating at 1000MHz
A. Modem Chip
Intel’s T3300 Wireless Base Station System on Chip (“Transcede “T3300”) delivers the required
performance for next generation wireless networks such as Long Term Evolution (LTE), in a single System
on Chip (SoC).
This SoC combines the latest Reduced Instruction Set Computer (RISC) processor technology with a high-
performance Digital Signal Processing (DSP) array supporting a simplified programming model. The device
offers hardware acceleration for application specific tasks, and a rich set of interfaces and features, which
allow the Transcede 3300 to provide a completely integrated solution covering the needed processing
capability from Internet Protocol (IP) (for example, S1) packets to IQ samples at extremely low power.
B. IEEE 1588v2
IEEE 1588v2 is a standard for precision time synchronization in local area networks. It works using
exchange of special Precision Time Protocol (PTP) frames.
C. Ethernet

JLT733A has two external ports: WAN, MGMT ports.
D. RF
This block communicates with the RF transceiver (AD9363) and the baseband chip (T3300) is controlled by
RF-SPI, and I/Q data is controlled by LVDS interface.
E. Power
The voltage range of power supplied by external source is 9V. It goes into power IC (DC/DC step down
converter and LDO etc.)
