Cellular Router Accessories
Semtech Gateways and Routers connect remote infrastructure securely to the enterprise network, and allows for remote configuration, deployment, monitoring and management of these assets with cloud-based or on-premises management systems. AirLink gateways and routers are engineered to be deployed out-of-the-box without additional programming and have the intelligence to stay connected.
Semtech AirLink J1939/1708 Telemetry Scanner Kits are designed to accompany MG 90 devices. The kit expands the capabilities of the device for advanced fleet management. It allows the routers to collect OBD-II vehicle telemetry data.
Semtech Router Accessory Asset Tags are active RFID tags tracked using Wi-Fi AP. They link up with AirLink oMG and MG90 routers and gateways and enables users to register and locate assets for tracking. They also include temperature sensor capabilities.
Basics of Switches, Routers & Hubs
Ethernet hubs, switches and routers connect computers to networks, devices and other computers.
Ethernet hubs are the least intelligent of the three devices. They simply take any message that is received and transmits it to every other device connected to that hub. For example, if CPU 1 on a network wants to send a message to CPU 5, it will send that message through the hub.The hub will then take that message and send it out to every connected device on that hub regardless of the intended target. When CPU 5 receives that message and wants to respond, it will send its response through the hub which sends it to every connected device. Ethernet hubs do not manage any data that is sent and tend to bog down networks. They also do not offer much security for the network. For these reasons, Ethernet hubs are are being replaced with network switches.
Switches transmit data from one device to another on the same network. Unlike a hub, switches use a switch table to learn where data came from and where to send it. Switch tables store Mac addresses and device ports. By storing this data, a switch can operate more efficiently than a hub, greatly reducing the traffic within the network.
Routers transfer data between devices while learning the location of those devices within the network. They are also a junction between two or more networks. An example of this would be a home router where the home network is connected to the Internet. Another example would be when the router connects two or more networks with different business functions. In addition to connecting two or more networks, a router offers important security features that help protect the network.
