SG Wireless™ Confidential 1
1. Introduction
The SGW2828-EVK is a evaluation kit designed for the development and PoC testing of applications based
on the SGW2828-01A LoRa Module. With the associated PC software, testing is easily enabled when two or
more users are connected and using the same frequency channel. The PC software is supposed by Windows
operating systems (Windows 10).
2. Required Tools
The SGW2828 Module’s long-range and wall-penetrating capabilities are best demonstrated when testing is
conducted with at least two individual users.
Each user should be equipped with the following:
a. SGW2828-EVK LoRa Evaluation Kit
b. +2dBm SMA antenna
c. Micro-USB cable
d. PC with Windows 10 or above
e. SGW2828-EVK PC Tool program

3. Operation Guide
a. Preparation
1. Download the SGW2828-EVK PC software file at https://sgwireless.com/static/tools/SGW2828-PC-
Tool.7z. Extract the file for the SGW2828-PC-Tool program (SGW2828-PC-Tool.exe).
2. Prepare the SGW2828-EVK by screwing on the antenna, then connect the SGW2828-EVK to the PC
with the micro USB cable (Figure 2). Toggle the power switch to ON.
3. Run the SGW2828-PC-Tool program.
b. Configuration of PC Software
1. Select the COM port number assigned for the connected SGW2828-EVK, then click ‘Connect’. The
COM port number may be different for each user, and can be found through Device Manager > Ports
