This part of ISO/IEC 14908 covers the complete physical layer (OSI layer 1) including the interface to the Medium Access Control (MAC) Sub-Layer and the.LoRaWAN is a media access control (MAC) protocol for wide area networks. A media access control address is a unique device address and each device or component in a network has a MAC address on the basis of which we can. MAC Address: Data-link layer supervises the physical addressing system called the MAC address for the networks and handles the access of the assorted network components to the physical medium.It receives IP traffic from gateways. Network Server #The network server manages the entire LoRaWAN network. The following figure shows a LoRaWAN gateway attached to a tall metal pipe (mast).Figure: A Kerlink outdoor gateway is installed at the port of Amsterdam.Usually, the receiver sensitivity of an outdoor gateway is higher than the receiver sensitivity of an indoor gateway. This type of gateway is intended for deployment places like cellular towers, the rooftops of very tall buildings, metal pipes (masts) etc. Indoor gateways provide coverage in difficult-to-reach indoor locations and are therefore suitable for use in homes, businesses and buildings.Outdoor gateways are suitable for providing coverage in rural, urban, and dense urban areas.
Message routing - forwarding uplink application payloads to the appropriate application server, forwarding downlink messages coming from any application server to the end device, forwarding Join-request and Join-accept messages between the devices and the join server (in v1.1 and 1.0.4). Message deduplication - eliminating duplicate messages received by multiple gateways Over-The-Air-Activation - see chapter End Device Activation Join Server #The Join Server processes join-request messages sent by end devices. The collected data can be interpreted by applying techniques like machine learning and artificial intelligence to solve business problems. A LoRaWAN network can have more than one application server. It also generates all the application-layer downlink payloads and sends them to the connected end devices through the network server. Acknowledgement of messages - providing acknowledgement of confirmed data messages and some MAC commands.The application server processes application-specific data messages received from end devices. Ti83 emulator macYou will learn how the Join Server processes the join-request message in the chapter End Device Activation. The Join Server is introduced in LoRaWAN 1.1 and 1.0.4.
