Milesight Routers: A Guide to the Industrial Cellular Router Range
Milesight is a growing name in industrial IoT networking, offering a range of 4G and 5G cellular routers built for M2M, remote monitoring and industrial automation. Here's an overview of the Milesight router lineup and where each model fits.
Who Are Milesight?
Milesight is a Xiamen-based IoT manufacturer that produces industrial cellular routers, LoRaWAN gateways, IoT sensors and video surveillance products. They've built a strong presence across smart metering, energy and utilities, transportation, retail and smart city applications, with deployments spanning Europe, Asia Pacific and the Americas.
In April 2026, Milesight formally launched Milesight Networks as a dedicated industrial networking division, signalling a deeper commitment to the cellular router and connectivity side of their business. The division focuses on industrial-grade routers for surveillance, energy, banking, transportation and smart retail.
Their router platform runs on a Linux-based OS with a web GUI, supports a wide range of VPN protocols (OpenVPN, IPsec, WireGuard, DMVPN, GRE, L2TP, PPTP, ZeroTier), and integrates with Milesight's own cloud management tools: MilesightVPN and DeviceHub.
The Milesight Router Range
Milesight's industrial routers fall into three tiers: Lite, Pro and Ultra. Each is built around an NXP or Qualcomm industrial-grade processor, housed in an IP30-rated aluminium enclosure, and rated for operation from -40°C to +70°C.
Lite Series: UR32L and UR32S
The UR32L is Milesight's entry-level industrial 4G router, designed to be compact and cost-effective. It provides a single SIM slot, 2 Fast Ethernet ports and 4G LTE connectivity. There's no Wi-Fi on the UR32L, which keeps the price down and makes it well suited to simple, space-constrained installations like data cabinets, ATMs and kiosk enclosures.
The UR32S adds Wi-Fi (802.11b/g/n) to the Lite formula, giving you wireless client connectivity on top of the cellular backhaul.
Both models support the full suite of VPN protocols, hardware watchdog for automatic recovery, and remote management via DeviceHub.
Typical applications: ATM connectivity, vending machines, data cabinet backup, point-of-sale, basic remote monitoring.
Pro Series: UR32 and UR35
The UR32 steps up to dual-SIM with auto-failover, 2 Fast Ethernet ports, Wi-Fi, RS232 (RS485 optional), digital I/O and a Python SDK for custom application development. It's the workhorse of the range, balancing capability with a compact form factor.
The UR35 builds on the UR32 with 5 Gigabit Ethernet ports (vs 2 Fast Ethernet on the UR32), RS232 and RS485 serial ports as standard, and enhanced I/O. It also supports DLMS protocol for smart metering, making it a natural fit for energy and utility deployments where Modbus or DNP3 integration is needed.
Both models are programmable via the embedded Python SDK, support MicroSD expansion, and are managed through DeviceHub or MilesightVPN.
Typical applications: smart metering, substation monitoring, industrial automation, oil and gas telemetry, rail freight monitoring, CCTV backhaul.
Ultra Series: UR75
The UR75 is Milesight's flagship 5G industrial router. It runs on a Qualcomm quad-core ARM Cortex-A55 processor with 512MB RAM and 8GB flash, and supports 5G Sub-6GHz with download speeds up to 4.67 Gbps. It also provides Wi-Fi 6 (dual-band, up to 1.8 Gbps), 5 Gigabit Ethernet ports, dual-SIM failover, RS232, RS485, digital I/O, GPS/GNSS and USB 3.0 (Type-C).
The UR75 is designed for high-bandwidth, low-latency applications where 4G isn't enough: HD video streaming from vehicles, real-time industrial control, high-density passenger Wi-Fi and smart city infrastructure.
Typical applications: 5G CCTV and video backhaul, public transport connectivity, industrial automation, smart city, high-bandwidth remote sites.
5G CPE: UF51 and UF31
Alongside the UR router series, Milesight also offers the UF51 (5G indoor CPE) and UF31 (5G USB dongle). These are simpler devices aimed at providing 5G fixed wireless access rather than full industrial routing. The UF51 is suited to offices, retail sites and temporary locations that need fast 5G broadband without a fixed line.
Remote Management: DeviceHub and MilesightVPN
All Milesight routers integrate with DeviceHub, a free cloud-based management platform that lets operators monitor device status, push firmware updates, configure settings and troubleshoot remotely across a fleet of routers. MilesightVPN provides secure remote access to devices without requiring a public IP address.
For operators managing large numbers of sites, DeviceHub offers user role management, alarm configuration, batch operations and operation logging. It's a comparable proposition to Teltonika's RMS, though with a different feature set and pricing model.
How Milesight Compares to Robustel
If you're evaluating industrial cellular routers, Robustel is another manufacturer worth considering alongside Milesight. The two ranges overlap in several areas: the Milesight UR32L competes with the Robustel R1511 (compact, cost-effective 4G with serial ports), the Milesight UR35 sits in similar territory to the Robustel R1520 (dual-SIM 4G, multiple Ethernet ports, serial I/O, programmable OS), and the Milesight UR75 goes head-to-head with the Robustel R5020 (industrial 5G, Wi-Fi, GNSS, dual-SIM).
Both manufacturers run proprietary Linux-based operating systems (Milesight's MilesightOS vs Robustel's RobustOS), both support a comparable set of VPN protocols, and both offer free cloud management platforms (DeviceHub vs RCMS). The differences tend to come down to specifics: Ethernet port count, Gigabit vs Fast Ethernet, analogue I/O support, Wi-Fi generation, global certification coverage and the depth of the SDK for custom application development.
The right choice depends on the project. Both brands produce solid, industrially rated hardware with good UK availability.
