Teltonika OTD140 for Outdoor Cellular Connectivity
27. May 2026 | Planegg
The compact outdoor 4G router OTD140 by Teltonika Networks is designed for installations requiring protected cellular connectivity outside buildings, directly at exposed mounting points, and in technical infrastructure environments.
Thanks to the weather protected enclosure in a compact form factor, the router can securely bring both LTE connectivity and Ethernet-based power delivery for technical infrastructures directly to the installation site. The platform supports 4G LTE with data rates of up to 150 Mbps downlink and 50 Mbps uplink, with fallback to 3G and 2G.
For flexible deployment topologies, the router integrates one PoE-In-Port and one PoE-Out-Port, allowing the device to be powered over Ethernet while also powering and connecting an additional PoE capable endpoint. In combination with RutOS functions such as routing, firewall, VLAN, failover, VPN and remote management, the OTD140 fits into both standard network infrastructures as well as technical or industrial communication environments.
With two Mini-SIM slots and automatic SIM switching, the OTD140 can support carrier redundancy and backup scenarios, particularly relevant for outdoor sites requiring stable data transmission under changing network conditions.
More information about the Teltonika OTD140 is available in the ATE Store. Atlantik Elektronik also provides a variety of solutions for connected charging systems, smart city infrastructures, and industrial IoT applications where the OTD140 can be integrated.
