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>>https://www.dragino.com/downloads/downloads/LoRa_Gateway/LG308-LG301/LG308_LoRaWAN_Gateway_User_Manual_v1.4.2.pdf]]
36 * Examples free public LoRaWAN server is: [[The Things Network>>url:https://www.thethingsnetwork.org/]].
37 * TTN provides the [[integration instruction>>url:https://www.thethingsnetwork.org/docs/applications/integrations.html]] for how to connect to Application servers.

46 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:

53 (((
54 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.
55 )))
56
57
58 = 4. Case 3: Standard LoRaWAN connection~-~- use Gateway built-in LoRaWAN server to connect to external IoT server =
59
60 **Application Scenario**:
61
62 * There is already IoT server but no LoRaWAN server.
63 * Not willing to use public LoRaWAN server nor built own LoRaWAN server.
64 *
65
66 **Suitable Gateway:**
67
68 * LoRaWAN Gateway model: LPS8v2.
69
70 **How it works:**
71
72 * a) LPS8v2 already includes a LoRaWAN server (TTN Stack v3). Enable this server in Web UI.
73 * b) Input End Nodes keys in LPS8v2 LoRaWAN server.
74 * c) Configure LPS8v2, End Node and LoRaWAN server frequency plan.
75 * d) Configure local LoRaWAN server to forward data to external Application Server.

82 = 5. Case 4: Standard LoRaWAN connection~-~- without LoRaWAN server, use ABP LoRaWAN End node =
83
84 Recommand to use Case3 as replacement.
85
86 Below gateways support this mode:
87
88 * 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]]
89
90 How it works:
91
92 * a) LoRaWAN End Nodes runs ABP mode
93 * b) No LoRaWAN server involved.
94 * c) Gateway stores keys from node and decode end nodes' data locally
95 * d) Gateway sends end node data to Application Server.

101 LoRaWAN connection without LoRaWAN server
102
103
104 = 6. Case 5: None standard LoRaWAN connection~-~- without LoRaWAN server, none standard LoRaWAN protocol, no security =
105
106 This method is to encryption part from LoRaWAN protocol and make the server side simple.

114
115 = 7. Case 6: Private LoRa connection~-~- without LoRaWAN server, use Raw LoRa protocol =
116
117 Below gateways support this mode:
118
119 * 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]]
120
121 How it works:
122
123 * a) LoRa End Node send Raw LoRa packet base on pre-define format
124 * b) No LoRaWAN server involved.
125 * c) Gateway parse the packet and get sensor ID and data.
126 * d) Gateway sends these data to Application Server.
