Low Power Wide Area Networks (lpwan): Technology Review And Experimental Study on Mobility Effect

LORA GATEWAY

Symphony Gateway LL-BST-8 is an industrial grade gateway developed by Symphony
Link, which can connect to thousands of Symphony Link modules. It can perform various LPWAN features like uplink and downlink communication, security updates and many more while using the Symphony Link protocol. The gateway can operate with 3G cellular, WiFi or 4G LTE for data backhaul, thus making it the right choice for conducting experiments in the outdoor environment where WiFi is unavailable. The key features of the LL-BST-8 gateway are:

• 
  Data connection via ethernet, GSM or WiFi
  
• 
  Interference mitigation algorithm
  
• 
  LoRaWAN and Symphony link ready
  
• 
  IP67 Water proof outdoor enclosure available
  
• 
  Adaptive data rates
  
• 
  Operates in 868MHz or 915MHz bandwidth

1. GATEWAY CONFIGURATION

Configuring the gateway for first use involves the following steps:

1. 
   The gateway can operate in three modes Ethernet, WiFi and Cellular. We use the WiFi mode as we connect the gateway to WiFi so that it can communicate with the conductor application. We connect the WiFi antenna to the WiFi jack and 915MHz anenna to the Ultra High Frequency (UHF) antenna jack.
   
2. 
   After powering on the gateway, connect the PC with the gateway using an Ethernet
   

cable.

3. 
   Navigate to gateway’s local page in the browser to 192.168.3.3 and login using the username ‘admin’ and password ‘password’.

4. 
   The gateway local page as shown in Figure 21 is reached which provides with options like connect to Internet, register gateway with conductor, software updates and also shows the current status of gateway.
   
5. 
   Since we are using WiFi, we connect the gateway by selecting the wireless tab and using the WiFi SSID and shared key. The Link Status changes from Disconnected to Activated once the gateway is able to successfully connect to the internet.
   
6. 
   Next step is to register the gateway to the Conductor platform. This can be done by clicking the Register Gateway button on the gateway homepage.
   
7. 
   Doing so pops up a conductor login box. If this is a new user, then the create user button is clicked to create a new user or else the user credentials are entered.
   
8. 
   For a new application we can create a new network or use an already existing Open Gateway network. On clicking the create network button the conductor creates a new network with unique name and adds it to the list. This name can be modified if needed.
   
9. 
   Once the gateway is registered the prompt disappears and the registration section on the gateway homepage shows that the gateway is registered.
