Product definition 

SZ11-GW-LoRa is an IoT application-level gateway router based on low-power, wide-area LoRaWAN protocol. It can provide low-power, mobile and secure local two-way wireless communication services for IoT devices. It supports LoRa, 2G/. 3G/4G, WiFi and GPS wireless communication functions, customers can easily deploy their own IoT control system to achieve customized intelligent services. 
The SZ11-GW-LORA adopts a star architecture design. The front-end node device provides single or multiple SZ11-GW-LORA gateways to achieve wireless communication between the terminal device and the cloud server, and can also connect to the cloud server through standard IP. . Can be widely used in smart parking, smart fire, animal husbandry positioning management, movable property (mortgage) supervision, power cable monitoring, smart street lights, smart agriculture, smart environmental protection and other fields.

2. Gateway interface introduction


3. Gateway basic information 

1) Gateway LAN port IP:, the DHCP server is enabled by default;  
2) Web page user default: root, login password: WelcomeTo2018;  
3) WAN defaults to open DHCP client, need to connect router;  
4) 4G/LTE Three types, China Three Netcom, European LTE system, US 4G standard, default automatic dialing;  
5) Wi-Fi hotspot: GW5000_+ gateway ID 6 characters at the end, password: gateway2018better;  
6) WAN and 4G network, traffic default use WAN priority, 4G standby, WAN port does not work, switch 4G traffic; gateway needs network that can access the Internet normally, network delay (ping is less than 50ms, use Ethernet, network speed should be greater than 2M; use 4G card The monthly traffic package should be greater than 6G (depending on the number of nodes);  
7) TF card file format default FAT32, when the remaining capacity is lower than 2G, the oldest log file will be cleared;   
8) Gateway ID naming rules: The physical address of the xx02+WAN port, the first two digits represent the regional frequency band used by the gateway;  
Note: 00 for CN470-510; 01 for EU863-870; 02 for US902-928; 03 for KR 915-928; 04 for INDIA86 5-867; 05 stands for AS923; 06 stands for AU915-928; 07 stands for EU433.     
9) Support foreign server TTN;  
10) Support gateway timing reporting status (WAN, LTE, LoRa, WiFi, TF card);  
11) Support gateway to report LoRa configuration parameters periodically;  
12) Support remote delivery modification of LoRa parameters;  
13) Support Remote upgrade;  
14) support remote restart; 
15) Support remote administrator login, maintenance and repair;  
16) Support button or WEB operation to restore factory settings;  
17) For security reasons, root login SSH2 and serial port have been disabled, and the login SSH2 and serial port accounts are not open to the public.
