| 23 | ((( | ||
| 24 | This is a standard LoRaWAN connection. Gateway will forward all end nodes' data to LoRaWAN server. The LoRaWAN server stores the sensor data and communicate with Application server. The Application server in charge for data process for different industrial solutions. | ||

| 35 | * Gateway set up instruction to LoRaWAN server. [[Gateway User Manual>>url:http://www.dragino.com/downloads/index.php?dir=LoRa_Gateway/LG308-LG301/&file=LG308_LoRaWAN_Gateway_User_Manual_v1.1.3.pdf]] | ||

| 48 | Basically, this is the same network topology as above, except users build the LoRaWAN server themselves. Below are two open source LoRaWAN servers commonly used: | ||

| 55 | ((( | ||
| 56 | Please note LoRaWAN server is for managing device and store sensor data, you still need to link the LoRaWAN server to an application server for your IoT solution to better analize the data and show to final clients. | ||

| 60 | = 4. Case 3: Standard LoRaWAN connection~-~- without LoRaWAN server, use ABP LoRaWAN End node = | ||
| 61 | |||
| 62 | Below gateways support this mode: | ||
| 63 | |||
| 64 | * LoRaWAN Gateway model: [[LPS8>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/148-lps8.html]], [[LG308>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/140-lg308.html]], [[DLOS8>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/160-dlos8.html]] | ||
| 65 | |||
| 66 | How it works: | ||
| 67 | |||
| 68 | * a) LoRaWAN End Nodes runs ABP mode | ||
| 69 | * b) No LoRaWAN server involved. | ||
| 70 | * c) Gateway stores keys from node and decode end nodes' data locally | ||
| 71 | * d) Gateway sends end node data to Application Server. | ||

| 80 | = 5. Case 4: None standard LoRaWAN connection~-~- without LoRaWAN server, none standard LoRaWAN protocol, no security = | ||
| 81 | |||
| 82 | This method is to encryption part from LoRaWAN protocol and make the server side simple. | ||

| 91 | = 6. Case 5:Private LoRa connection~-~- without LoRaWAN server, use Raw LoRa protocol = | ||
| 92 | |||
| 93 | Below gateways support this mode: | ||
| 94 | |||
| 95 | * LoRaWAN Gateway model: [[LG01-N>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/143-lg01n.html]], [[OLG01-N>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/144-olg01n.html]], [[LG02>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/135-lg02.html]], [[OLG02>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/136-olg02.html]] | ||
| 96 | |||
| 97 | How it works: | ||
| 98 | |||
| 99 | * a) LoRa End Node send Raw LoRa packet base on pre-define format | ||
| 100 | * b) No LoRaWAN server involved. | ||
| 101 | * c) Gateway parse the packet and get sensor ID and data. | ||
| 102 | * d) Gateway sends these data to Application Server. | ||
