The Milesight UR75 is an industrial-grade 5G router built for M2M and IoT deployments where high throughput, serial connectivity and environmental resilience all matter in the same box. It’s the flagship of Milesight’s Ultra Series, pairing 5G Sub-6GHz connectivity with Wi-Fi 6, dual SIM failover and a proper industrial spec sheet — wide temperature range, IP30 metal enclosure, DIN rail mounting.
Where the smaller UR32/UR35 routers cover most everyday 4G connectivity jobs, the UR75 is aimed at sites that need real bandwidth: HD video backhaul, multi-site VPN aggregation, or just future-proofing a deployment against the eventual retirement of 4G in a given region.
Quick Take
A serious step up from Milesight’s 4G range — genuine 5G throughput, Wi-Fi 6, and the serial/IO ports that make it a proper industrial gateway rather than just a fast modem. Worth the premium over the UR32/UR35 if your site actually needs the bandwidth or you want 5G headroom built in now.

Good to know The UR75 is available in standard and PoE-output variants (4 of the 5 Ethernet ports supplying PoE PSE on the latter) — useful if you’re powering cameras or access points directly off the router rather than running separate injectors.
Applications
CCTV & Video Backhaul5G throughput handles multi-stream HD/4K camera feeds from remote or temporary sites without the bandwidth ceiling of 4G.
Smart Grid & SubstationsWide temperature range and DI/DO make it suited to outdoor cabinets and unmanned grid infrastructure.
Industrial AutomationRS232/RS485 and Modbus gateway support connect directly into PLCs and SCADA systems.
Multi-Site VPN AggregationDual SIM failover plus a full VPN stack suits retail, banking or distributed branch networks needing reliable always-on connectivity.
Digital Signage & MediaHigh-speed downlink supports media-heavy digital signage and kiosk deployments at scale.
Fleet & TelemetryBuilt-in GNSS variants support vehicle tracking and remote telemetry equipment.
About Milesight
Milesight is a global IoT manufacturer producing industrial cellular routers, LoRaWAN sensors and gateways, and AIoT camera systems. The Ultra Series routers (which the UR75 belongs to) sit at the high-performance end of their cellular router range, built around the same DeviceHub management ecosystem used across their other product lines — so a fleet of UR75s can be monitored, configured and updated alongside other Milesight hardware from a single platform.
Other Routers in the Milesight Range

SIM Cards for Industrial Routers
An industrial router is only as reliable as the SIM behind it. For deployments like the UR75 — multi-site, often unattended — a standard consumer SIM usually isn’t the right fit. Worth considering instead:
- Multi-network SIMs that roam across several mobile networks automatically, so a single dead cell doesn’t take the site offline.
- Fixed IP SIMs, which simplify direct VPN tunnels back to a router without needing a dynamic DNS workaround.
- Data-only M2M SIMs with pooled data plans across a fleet of routers, which tend to work out considerably cheaper than consumer tariffs at scale.
Antennas
The UR75’s 5G performance is only as good as the antennas feeding it. For fixed installations, a higher-gain external 5G/4G antenna mounted clear of the cabinet — rather than relying on stub antennas screwed straight onto the unit — usually makes a meaningful difference to signal stability, particularly in steel cabinets or basement plant rooms. Where GNSS is in use, a separate GPS antenna with clear sky view is worth the extra cable run.
