1. Overview
S3-915M is a standard LoraWan node Module designed and manufactured by BuildingLink, working frequency
band 902-928MMHZ, supports CLASS-A/CLASS-C node type, supports ABP/OTAA two network access modes, and at
the same time, this module With a variety of low-power modes, the external communication interface uses a standard
UART. Users can easily access the standard LoraWan network through AT commands, making it an excellent choice for
IoT applications.

1.2 Parameter Description
When designing the power supply circuit for the module, it is recommended to reserve more than 30% of the
remaining amount, and the whole machine is conducive to long-term stable operation；
The current required for the instant of launch is large but often because the launch time is extremely short, the total
energy consumed may be smaller；
When the customer uses an external antenna, the impedance matching degree between the antenna and the module
at different frequency points will affect the magnitude of the emission current to varying degrees;
The current consumed by the RF chip in the pure receiving state is called the receiving current. Some RF chips
with communication protocols or developers have loaded some self-developed protocols on the whole machine,
which may cause the receiving current of the test to be too large；
The current in the purely receiving state is often mA level, and the "receiving current" of the μA level needs to be
processed by the developer through software;
The shutdown current is often much smaller than the current consumed by the power supply part of the whole
machine at no load, without being overly demanding;
Since the material itself has a certain error, a single LRC component has an error of ±0.1%. However, since a
plurality of LRC components are used in the entire RF loop, there is a case where error accumulation occurs,
resulting in a difference in emission current and reception current of different modules;
Reducing the transmit power can reduce power consumption to some extent, but reducing the transmit power
emissions for a number of reasons reduces the efficiency of the internal PA.

2. Terms and definitions
2.1 LoRa
LoRa is one of the LPWAN communication technologies, the full name is Long Range Radio; the company that currently
dominates the technology is the semtech company;
LoRa's main ISM brand is available worldwide for free bands: 433MHz, 470MHz, 868MHz, 915MHz, etc.
Features: Low power consumption, long distance, low cost.
2.2 LoRaWAN
The LoRa Alliance is an open, non-profit organization led by Semtech in March 2015. The Alliance publishes a
low-power WAN standard based on the open source MAC layer protocol: the LoRaWAN protocol standard.
Network topology: star structure
Network composition: LoRa module, gateway (Gateway or base station), Server (including Network Server, Network
control, Application Server).
LoRaWAN divides the LoRa nodes into three categories: A/B/C:
Two-way transmission terminal(Class A)：
Class A's terminal will follow two short downlink receiving windows after each uplink to achieve two-way
transmission. The terminal arranges transmission time slots based on its own communication requirements, with a small
change on the basis of random time (ie, ALOHA protocol). This Class A operation provides the lowest power
consumption end system for the application, and only requires the application to perform downlink transmission of the
server in a short time after the terminal uplink transmission. The downstream transmission of the server at any other time
has to wait for the next uplink of the terminal.
Two-way transmission terminal delineating a reception slot(Class B)：
Class B terminals have more receive slots. In addition to Class A's random receive window, Class B devices also
open other receive windows at the specified time. In order for the terminal to open the receiving window at a specified
time, the terminal needs to receive a time-synchronized beacon (Beacon) from the gateway. This allows the server to
know when the terminal is listening.
Two-way transmission terminal that maximizes the reception slot (Class C)：
The terminal of Class C basically keeps the receiving window open, and only closes briefly when sending. Class C
terminals consume more power than Class A and Class B, but the delay from the server to the terminal is also the
shortest.
Note: The E78-470LN22S supports both Class A and Class C device types.
2.1.3 ADR
ADR Chinese is called adaptive data rate. In the loraWan network system, in order to maximize the battery life and
overall network capacity of the terminal device, the LoRaWAN network server separately manages the data rate and RF
output of each terminal device through an adaptive data rate (ADR) algorithm, through ADR technology, In the
LORAWAN system, the server automatically updates the rate of setting the node according to the signal receiving
capability of the node. The distance is far, the rate is low, and the distance is high, so the actual bandwidth greatly
improves the effective bandwidth and load capacity of the network.
