Teltonika RUT281, RUT981 & RUT986: New Global LTE Cat 4 Routers with Telit Modems — Full Technical Review

In February 2026, Teltonika Networks launched three new industrial cellular routers built around a single global Telit LTE Cat 4 modem: the RUT281, RUT981, and RUT986. These aren’t incremental refreshes — they represent a fundamental shift in how Teltonika approaches its LTE Cat 4 lineup, consolidating regional modem variants into one global hardware SKU per model.

This article breaks down exactly what’s inside each router, covers the part numbers and ordering codes, examines the Telit modem and band support in detail, lists the full regulatory certifications, compares each model against its predecessor, and explains where each fits in real-world IoT and industrial deployments.

Everything in this article is sourced directly from the official Teltonika datasheets (v1.00) published in February 2026.

Why Global Matters: The Shift to Telit

Historically, Teltonika shipped multiple regional variants of its LTE routers. A RUT241 destined for Europe carried a different modem configuration to one shipping to North America or Asia-Pacific. That meant separate SKUs, separate stock, and careful ordering to match bands to deployment regions.

The new RUT281, RUT981, and RUT986 each use a Telit LTE Cat 4 module that covers a broad set of 4G, 3G, and 2G bands across all major global markets in a single piece of hardware. For integrators, distributors, and managed service providers deploying across multiple countries, this is a significant operational simplification.

All three models share the same band configuration:

• 4G LTE (FDD): B1, B2, B3, B4, B5, B7, B8, B8_US, B9, B12, B13, B14, B18, B19, B20, B25, B26, B28
• 3G UMTS: B1, B2, B4, B5, B6, B8, B19
• 2G GSM: B2, B3, B5, B8

That covers the core LTE bands for Europe (B3, B7, B8, B20, B28), North America (B2, B4, B5, B12, B13, B14, B25, B26), Asia-Pacific (B1, B3, B5, B8, B18, B19, B28), and Latin America. Band 13 and Band 14 inclusion is notable for US FirstNet and Verizon deployments. Band 28 covers the increasingly important 700 MHz APT band used across Asia-Pacific and parts of Europe.

The 3GPP Release 10 compliance confirms LTE Cat 4 performance: up to 150 Mbps download and 50 Mbps upload on 4G, with 3G and 2G fallback.

Teltonika RUT281 — Compact Global LTE Cat 4 Router

The RUT281 is the smallest and most cost-effective of the three. It’s positioned as a compact, entry-level industrial LTE router for space-constrained deployments where a reliable global cellular connection is needed without the bells and whistles of serial ports or GNSS.

Part Numbers & Ordering Codes

HS Code: 851762 | HTS: 8517.62.00

Hardware Specifications

What’s in the Box

The standard package includes the RUT281 router, quick start guide, 9W PSU (region-specific), 2 x mobile SMA antennas, 1 x Wi-Fi SMA antenna, 1.5m Ethernet cable, and SIM adapter kit.

eSIM & SIM Architecture

The RUT281 has one physical SIM slot (Mini SIM 2FF) plus a built-in consumer eSIM supporting up to 7 downloadable profiles. This is not a dual physical SIM design — it’s SIM + eSIM with automatic failover between them based on signal strength, data limits, roaming status, or network availability.

The eSIM supports bootstrap provisioning, allowing initial profile download without needing a pre-inserted physical SIM. This is a significant advantage for zero-touch deployments managed through Teltonika’s RMS platform.

Software & Protocol Support

Despite its compact size, the RUT281 runs the full RutOS (OpenWrt-based) stack including:

• Routing: BGP, OSPF v2, RIP v1/v2, EIGRP, NHRP, policy-based routing
• VPN: OpenVPN (27 encryption methods), IPsec (IKEv1/v2, 14 encryption methods), WireGuard, GRE, PPTP, L2TP, Stunnel, DMVPN, SSTP, ZeroTier, Tinc
• Industrial Protocols: Modbus TCP (client/server), OPC UA (client/server), DNP3 (station/outstation via TCP), DLMS/COSEM (client via TCP), Modbus MQTT Gateway
• Security: WPA3, 802.1x, RADIUS, TACACS+, VLAN, DDoS prevention, certificate management (including Let’s Encrypt and SCEP)
• Cloud: RMS, Azure IoT Hub, AWS IoT Core, ThingWorx, Cumulocity
• Management: Web UI, SSH, SNMP v1/v2/v3, TR-069, MQTT broker, JSON-RPC, FOTA

Note that the RUT281’s Modbus and DNP3 support is TCP only — there are no serial ports on this model.

RUT281 vs RUT241: What’s Changed?

The RUT241 was Teltonika’s long-standing compact Cat 4 router, shipped in multiple regional variants with a Quectel modem. The RUT281 replaces it with:

• Global Telit modem — one SKU worldwide instead of regional variants
• Integrated eSIM — the RUT241 had no eSIM capability
• Full industrial protocol stack — Modbus, OPC UA, DNP3, DLMS/COSEM were not available on all RUT241 firmware versions
• Same compact form factor — the 83 × 25 mm footprint is maintained
• Same 10/100 Mbps Ethernet — no upgrade to gigabit at this tier

For existing RUT241 deployments, the RUT281 is a direct physical replacement with expanded software capabilities and global connectivity.

Best Use Cases

The RUT281 is ideal for distributed IoT deployments requiring compact hardware: CCTV backhaul, vending machine telemetry, digital signage, POS terminals, kiosk connectivity, remote monitoring of small cabinets, and backup WAN links in tight enclosures. Its ultra-low power consumption (under 4W max) makes it suitable for solar-powered or battery-backed installations.

Teltonika RUT981 — Global 4G Router

The RUT981 steps up to a mid-tier platform with quad Ethernet ports, 2×2 MIMO Wi-Fi, dual physical SIM slots, and the same global Telit Cat 4 modem. It’s positioned as a versatile commercial and light-industrial router for deployments that need more LAN connectivity than the compact RUT281 can offer.

Part Numbers & Ordering Codes

HS Code: 851762 | HTS: 8517.62.00

Hardware Specifications

What’s in the Box

Standard package includes the RUT981 router, quick start guide, 9W PSU, 2 x mobile SMA antennas, 2 x Wi-Fi SMA antennas, 1.5m Ethernet cable, and SIM adapter kit.

Key Differences from RUT281

The RUT981 adds several capabilities that matter for more complex deployments:

• Dual physical SIM slots — two 2FF Mini SIM slots plus eSIM, enabling physical SIM failover alongside eSIM profiles
• 4 x Ethernet ports — 3 LAN + 1 WAN (configurable) for connecting multiple wired devices
• 2×2 MIMO Wi-Fi — improved wireless throughput and reliability compared to RUT281’s single-stream radio
• Up to 100 simultaneous Wi-Fi clients — versus 50 on the RUT281
• 3G speeds up to 42 Mbps — the RUT981’s modem configuration supports DC-HSPA+ at 42 Mbps download, compared to 21 Mbps on the RUT281
• Hotspot 2.0 (Passpoint) — seamless Wi-Fi onboarding for enterprise environments
• EoIP and OpenConnect VPN — additional tunnelling options not available on the RUT281

Software & Protocol Support

The RUT981 shares the same RutOS foundation as the RUT281 but adds:

• Hotspot 2.0 for enterprise Wi-Fi roaming
• EoIP (Ethernet over IP) for MikroTik interoperability
• OpenConnect VPN client
• Data to Server with custom Lua scripting capability

Industrial protocol support mirrors the RUT281: Modbus TCP, OPC UA, DNP3 (TCP only), DLMS/COSEM (TCP only), and Modbus MQTT Gateway. Without serial ports, all industrial protocol connections are IP-based.

RUT981 vs RUT951: What’s Changed?

The RUT951 was one of Teltonika’s best-selling mid-tier 4G routers, available in numerous regional variants. The RUT981 replaces it with:

• Global Telit modem — eliminates the need for EU/US/APAC-specific SKUs
• Integrated eSIM — the RUT951 required physical SIM cards only
• Simplified ordering — five order codes cover all markets
• Same physical platform — 110 × 50 × 100 mm form factor maintained

One important note: the RUT981 datasheet specifies 10/100 Mbps Ethernet ports. Some Teltonika marketing materials reference 10/100/1000 Mbps, but the detailed technical datasheet consistently states 10/100 Mbps for both WAN and LAN ports. Verify with your distributor if gigabit Ethernet is critical to your deployment.

Best Use Cases

The RUT981 suits SME branch connectivity, retail networks requiring multiple wired POS or CCTV devices, EV charger communication modules, building management system (BMS) gateways, and any deployment where you need four Ethernet ports with reliable cellular failover. The 2×2 MIMO Wi-Fi makes it a capable wireless access point for small commercial spaces.

Teltonika RUT986 — Industrial Global LTE Cat 4 Router

The RUT986 is the flagship of the new global Cat 4 range. It adds everything an industrial deployment demands: RS232 and RS485 serial interfaces, multi-constellation GNSS, comprehensive analogue and digital I/O, a relay output, micro SD card storage, USB connectivity, BACnet routing, and VRF support.

This is a full industrial gateway, not a connectivity router.

Part Numbers & Ordering Codes

HS Code: 851762 | HTS: 8517.62.00

Hardware Specifications

What’s in the Box

Standard package includes the RUT986 router, quick start guide, 9W PSU, 2 x mobile magnetic SMA antennas, 2 x Wi-Fi magnetic SMA antennas, 1 x GNSS adhesive SMA antenna, connectors set (for I/O and serial), 1.5m Ethernet cable, and SIM adapter kit.

Industrial I/O in Detail

The RUT986’s I/O capabilities go well beyond basic digital switching. The galvanically isolated digital input (0–30V range) protects the router from ground loops and voltage transients common in industrial environments. The analogue input with 4–20 mA current loop capability enables direct connection to industrial sensors — flow meters, pressure transducers, temperature transmitters — without needing an external converter. The SPST relay output rated at 40V/4A can switch loads directly, whether that’s a warning light, a ventilation fan, or an external contactor coil.

All I/O events can trigger actions: email alerts, SMS notifications, RMS events, or custom Lua scripts via the I/O juggler.

Serial Gateway Capabilities

The RS232 and RS485 ports transform the RUT986 into a proper serial gateway. The serial interfaces support:

• Console access to connected devices
• Serial over IP tunnelling
• Modem emulation
• Modbus RTU gateway — bridging Modbus RTU devices on serial to Modbus TCP over the network
• NTRIP Client for GNSS correction data

RS485 supports both full duplex (4-wire) and half duplex (2-wire) configurations at baud rates from 300 to 115,200 — covering everything from legacy SCADA equipment to modern industrial controllers.

Industrial Protocol Stack

This is where the RUT986 separates itself from the RUT281 and RUT981. Because it has serial interfaces, it unlocks the full depth of Teltonika’s industrial protocol support:

• Modbus RTU (RS232, RS485) and Modbus TCP — client and server modes
• DNP3 — station and outstation modes over RS232, RS485, TCP, and USB
• OPC UA — client and server over TCP
• BACnet Router — over RS485 and TCP, making the RUT986 suitable for building automation integration
• DLMS/COSEM — client mode over RS232, RS485, and TCP for smart metering
• Modbus MQTT Gateway — bridging Modbus to MQTT brokers for cloud integration
• Data to Server — HTTP(S), MQTT, Azure MQTT with custom Lua scripting

The combination of Modbus RTU/TCP, DNP3, and BACnet in one device covers the three most common industrial communication protocols across energy, water, building automation, and manufacturing.

GNSS & Location

The five-constellation GNSS receiver (GPS, GLONASS, BeiDou, Galileo, QZSS) provides accurate positioning data accessible via the web UI, SMS, NMEA 0183 output, or RMS. Geofencing with multiple configurable zones enables location-based triggers, and NTRIP support allows the router to receive RTCM correction data for centimetre-level accuracy when paired with compatible equipment.

Advanced Networking

The RUT986 adds capabilities not found on the RUT281 or RUT981:

• VRF (Virtual Routing and Forwarding) — initial support for network segmentation at the routing level, critical for multi-tenant or utility deployments
• Port Mirroring — for network traffic monitoring and diagnostics
• BACnet Router mode — for building automation protocol bridging

RUT986 vs RUT956: What’s Changed?

The RUT956 was Teltonika’s established industrial LTE Cat 4 gateway with serial, GNSS, and I/O. The RUT986 builds on it with:

• Global Telit modem — single worldwide SKU replacing multiple regional variants
• Integrated eSIM — remote carrier provisioning without physical SIM swaps
• Consistent global band support — the same 18 LTE bands across all markets
• Same proven hardware platform — matching dimensions and I/O layout

For energy sector deployments — solar PV monitoring, BESS telemetry, EV charger management, substation communications — the RUT986 is the direct upgrade path from the RUT956.

Best Use Cases

The RUT986 is engineered for serious industrial applications: substation SCADA connectivity, solar farm inverter monitoring via Modbus RTU, building management system integration via BACnet, water treatment plant telemetry, traffic management systems, smart metering infrastructure (DLMS/COSEM), and any deployment combining serial equipment connectivity with cellular backhaul.

The Telit Modem: Why It Matters

The choice of Telit as the modem vendor is significant for several reasons beyond just band coverage.

Long-term availability. Telit has a strong track record of maintaining modem module production for extended periods — critical for industrial products with 5–10+ year deployment lifecycles. Teltonika explicitly positions these routers around “dependable long-term availability.”

Global carrier certification heritage. Telit modules carry pre-existing carrier certifications across numerous operators worldwide. While the router itself still requires its own regulatory approvals (which all three models carry), having a Telit module inside streamlines the carrier approval process.

Proven industrial reliability. Telit modules are widely used across industrial M2M applications. The RF stability and thermal performance of Telit Cat 4 modules is well-established in harsh environment deployments.

Single SKU logistics. By using a module that covers all target bands in one hardware design, Teltonika eliminates the regional variant problem entirely. This is better for distributors, better for integrators maintaining spares, and better for end users who may redeploy hardware across markets.

Shared Software Platform: RutOS

All three models run RutOS, Teltonika’s OpenWrt-based industrial Linux operating system. This provides:

• Firmware customisation via SDK (Busybox shell, Lua, C, C++)
• GPL customisation for white-label firmware and web UI branding
• Package Manager for installing additional software
• FOTA updates via RMS for fleet-wide firmware management
• Configuration backup and profiles for rapid deployment
• Web API (beta) for programmatic device management

The consistent software platform across all three models means configurations, VPN profiles, and management workflows are transferable between the RUT281, RUT981, and RUT986 — useful when deploying a mix of models across a network.

Practical Deployment Considerations

Antenna Selection Still Matters

A global modem doesn’t eliminate the need for careful antenna selection. The wide band range (from 700 MHz to 2600 MHz for LTE alone) means broadband antennas are essential. The included SMA antennas are suitable for benchtop testing, but production deployments — especially in enclosures or outdoor cabinets — should use properly specified wideband LTE antennas covering all required bands with appropriate gain patterns.

For external antenna installations, SMA and RP-SMA connectors are standard, but consider cable loss: keep LTE antenna cables as short as practical and use low-loss coaxial (LMR-195 or LMR-400 equivalent) for runs over 1 metre.

eSIM Provisioning at Scale

The consumer eSIM on all three models supports up to 7 downloadable profiles, but does not include data plans. You’ll need an eSIM management platform or an eSIM-capable MVNO/carrier to provision profiles remotely. Combined with Teltonika RMS, this enables true zero-touch deployment: ship the router, power it on, provision the eSIM profile remotely, and configure the device — all without a site visit.

Power Supply Planning

All three models accept 9–30 VDC, making them compatible with standard 12V and 24V industrial power systems. Passive PoE (Mode B, 9–30 VDC, non-standard) is available on LAN1 for cable-powered installations, but note this is not compatible with IEEE 802.3af/at/bt standard PoE.

Summary: Which Model Do You Need?

Choose the RUT281 when you need a compact, low-power global LTE router for simple IoT connectivity. Ideal for CCTV, vending, signage, and single-device backhaul where space is tight and requirements are straightforward.

Choose the RUT981 when you need multiple Ethernet ports and stronger Wi-Fi for branch networks, retail environments, or multi-device installations. The dual SIM slots and 2×2 MIMO make it a more capable platform for commercial deployments.

Choose the RUT986 when you need industrial-grade integration: serial device connectivity (Modbus RTU, DNP3 over RS485), GNSS positioning, analogue sensor inputs, relay control, or BACnet routing. This is the right choice for energy, utilities, SCADA, and building automation.

All three share the same global Telit Cat 4 modem, eSIM capability, RutOS software stack, and comprehensive regulatory certifications. The choice comes down to how many interfaces and industrial features your deployment requires.
