105
106 ~1. Register LPS8v2 gateway to TTN so provide a LoRaWAN coverage. See section “[[Gateway Registration for Semtech UDP ~~-~~-~> Primary LoRaWAN Server>>url:http://wiki.dragino.com/xwiki/bin/view/Main/Notes%20for%20TTN/#H2.A0GatewayRegistrationforSemtechUDP]]” 
107
108 2. Register LA66 Shield to TTN and uplink Temperature to TTN. See section “[[Example: Log Temperature Sensor(DHT11) and send data to TTN, show it in Node-RED>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20LoRaWAN%20Shield%20User%20Manual/#H1.7A0Example:LogTemperatureSensor28DHT1129andsenddatatoTTN2CshowitinNode-RED.]].”
109
110 3. Register LA66 USB to TTN and track people location. See “[[Example: Use of LA66 USB LoRaWAN Adapter and mobile APP>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.9A0Example:UseofA0LA66USBLoRaWANAdapterandmobileAPP]]”
