The RUT901 is positioned by Teltonika as an industrial cellular router and brings the feature set of the RUT9-series platform to applications requiring dependable cellular connectivity and network redundancy. Its dual-SIM capability allows automatic SIM switching based on conditions such as weak signal, data limits, roaming, network availability, or failed data connections.
4G LTE Cat 4 Connectivity
The RUT901 supports 4G LTE Cat 4 connectivity with theoretical cellular speeds of up to 150 Mbps download. It also supports 3G and 2G cellular technologies, depending on the specific hardware version, supported bands, and mobile operator.
Teltonika provides cellular monitoring information including signal strength, SINR, RSRP, RSRQ, connected band, IMSI, ICCID, and transmitted or received data. These features can help administrators monitor cellular link quality and troubleshoot connectivity issues.
Dual SIM with Automatic Failover
One of the key features of the RUT901 is its dual-SIM configuration. The router can automatically switch between SIM cards according to configurable conditions such as weak signal, data limits, SMS limits, roaming, unavailable network, network denial, or failed data connection.
This provides an additional layer of connectivity redundancy for remote sites, industrial equipment, transportation systems, and other installations where maintaining an internet connection is important.
Four Ethernet Ports
The RUT901 includes four 10/100 Mbps Ethernet ports: one WAN port and three LAN ports. The WAN interface can also be configured as a LAN port, providing additional flexibility when designing the network. All Ethernet interfaces support auto MDI/MDIX.
The Ethernet interfaces can connect industrial controllers, computers, surveillance equipment, network switches, automation systems, and other wired devices to the cellular or wired WAN connection.
Wi-Fi 4 Wireless Connectivity
The RUT901 supports IEEE 802.11b/g/n Wi-Fi and can operate in Access Point or Station mode. Teltonika specifies support for up to 100 simultaneous Wi-Fi connections, making it suitable for local wireless access in business, industrial, and remote-site deployments.
Wireless features include multiple security modes, SSID management, MAC-based access control, client separation, captive portal functionality, hotspot capabilities, and support for external RADIUS authentication.

WAN Failover and Network Backup
The RUT901 supports automatic network failover using available connectivity sources. Mobile, wired, and Wi-Fi WAN connections can be incorporated into backup scenarios, allowing the router to switch to an available connection when the primary path fails.
This makes the router useful for businesses, industrial facilities, remote monitoring systems, and branch locations where uninterrupted network access is important.
Routing and Network Management
The RUT901 supports static and dynamic routing, including protocols such as BGP, OSPF v2, RIP v1/v2, and NHRP on supported firmware. It also supports IPv4, IPv6, DHCP, DNS, PPPoE, VRRP, VLAN, MQTT, SSH, and other network protocols.
Traffic management and QoS features can be used to prioritize traffic based on source, destination, service, protocol, or port. Connection monitoring functions include Ping Reboot, Wget Reboot, periodic reboot, LCP, and ICMP-based link inspection.
Security Features
The RUT901 provides firewall, NAT, NAT-T, DMZ, access control, VLAN separation, MAC filtering, and attack-prevention features. Teltonika documents protection mechanisms for threats including SYN flooding, SSH attacks, HTTP/HTTPS attacks, and several types of port scanning.
Authentication options include pre-shared keys, digital certificates, X.509 certificates, TACACS+, and RADIUS, depending on the selected service or configuration.
VPN and Remote Management
The RUT901 supports VPN and secure remote-access functionality as part of its networking feature set. It is also compatible with the Teltonika Remote Management System (RMS), allowing supported devices to be remotely monitored, accessed, configured, and managed.
Remote management is particularly useful when routers are deployed at unmanned or geographically distributed locations where physical access is difficult.
Industrial I/O
The RUT901 includes one digital input and one digital open-collector output. These interfaces can be integrated into suitable monitoring and automation applications, allowing the router to interact with external industrial equipment or status signals.
SMS and Cellular Management
The RUT901 provides extensive SMS functionality, including sending and reading SMS messages, scheduled SMS, SMS autoreply, SMS-to-email, email-to-SMS, SMS-to-HTTP, and other supported messaging functions. Cellular management also includes APN configuration, operator lists, band management, and SIM-related controls.
Industrial Construction
The RUT901 uses an aluminum housing with plastic panels and supports DIN-rail as well as flat-surface mounting. This construction makes it suitable for industrial cabinets, automation panels, network enclosures, and other professional installations.
The router is designed for professional environments where cellular connectivity, network redundancy, remote management, and industrial installation options are required.
