Outdoor 4G and 5G Routers: The Complete Guide
Purpose-built weatherproof units, enclosure kits, PoE chaining, out-of-band management, rapid deployment, eSIM without a ladder, and how to choose the right SIM – everything you need to put reliable cellular connectivity outside.
Why put a router outside?
The physics of cellular signals favour an outdoor installation. Every material a radio signal passes through costs signal – brick walls attenuate 4G signals by 10-15 dB, and 5G at 3.5 GHz can lose 20 dB or more crossing a single external wall. That is not a marginal penalty. It is the difference between excellent signal and a router that struggles to hold a stable connection.
Moving the cellular radio outside eliminates that loss. The antenna is in clear air, the modem is receiving the strongest possible signal, and the connection to the local network comes back inside over a single Ethernet cable. One cable in, connectivity out. The market has organised itself around four distinct ways of implementing this, from purpose-built outdoor units to portable kits you can carry in a hard case.
Indoor router with external antenna cables versus purpose-built outdoor router – one cable replaces four, with no signal loss in coax.
Four approaches to outdoor cellular connectivity
Purpose-built outdoor unit
Designed from the ground up for outdoor mounting – weatherproof housing, internal antennas, PoE powered. One cable, cleanest install, best RF performance.
Indoor router in a branded enclosure
A proven indoor router (RUT200, RUT901, RUTX50 etc.) inside a purpose-built weatherproof kit from QUWireless or GTT Wireless, with integrated external antennas.
Indoor router in a generic IP box
Any compact router in an off-the-shelf weatherproof enclosure. Lowest cost, highest RF compromise. Fine for 4G monitoring; not recommended for 5G.
A fourth category sits apart from permanent installation entirely: rapid-deployment portable units – self-contained connectivity kits for temporary or emergency use, operational within minutes. Covered in its own section below.
Purpose-built outdoor routers
Purpose-built outdoor routers have expanded rapidly with 5G, for a clear reason: 5G MIMO antenna systems are more complex than 4G. Running four coaxial cables for 5G MIMO from an outdoor antenna array to an indoor router is slow to install, adds signal loss at every connector and metre of coax, and looks a mess. A purpose-built outdoor unit with eight internal antennas and one PoE cable back to the building is better on every dimension except unit cost.
Teltonika OTD140 – outdoor 4G
Teltonika OTD140
Teltonika’s entry-level outdoor router. Cat 4 and a single SIM – right for 4G applications where budget matters and dual-SIM resilience is not required. The dual PoE ports are a practical advantage: PoE-in from the building, PoE-out to a downstream device at the same pole. One Cat6 cable up, the OTD140 powered and a downstream camera or AP also powered. RMS-managed. Solid choice for sheltered outdoor positions.
Teltonika OTD500 – outdoor 5G with PoE-out and eSIM
Teltonika OTD500
The OTD500 is the 5G upgrade path from the OTD140, and it retains the dual PoE port architecture: one cable in from the building delivers both power and data to the router, and the second Ethernet port delivers PoE-out to a downstream device at the same mounting point – a PTZ camera, a LoRaWAN gateway, an outdoor access point. Dual SIM with auto-failover plus eSIM with up to 7 downloadable profiles. The 6kV lightning protection is standard specification for any exposed outdoor position. RMS-compatible for remote fleet management.
Zyxel NR7302 – 5G FWA outdoor
Zyxel NR7302
The NR7302 is squarely aimed at fixed wireless access: internet service providers and businesses replacing fixed broadband with 5G. Its 9 dBi gain antennas outperform most competitors’ integrated antennas; IP67 is a step above the OTD500’s IP55; the 2.5G Ethernet port means the backhaul cable is not a bottleneck even at peak 5G throughput. One of the most widely deployed outdoor 5G units in European FWA rollouts, which translates to mature firmware and broad operator support. eSIM support for remote profile switching.
MikroTik outdoor cellular range
MikroTik are a Latvian networking hardware company with an unusually broad outdoor cellular product range and a reputation for strong RF performance at lower price points than the industrial brands. RouterOS is their operating system – powerful and highly configurable, with a steeper learning curve than Teltonika or Milesight equivalents. For technically capable teams, the MikroTik range offers excellent value for money.
MikroTik ATL 5G R16
MikroTik’s first dedicated outdoor 5G router and a significant product. The ATL 5G R16 uses a 3GPP Release 16 modem with built-in eSIM and powerful directional antennas: four high-gain mid-band antennas and four low-band antennas including full Band 28 support at 700 MHz – the rural coverage band that matters most for UK deployments. IP66 rated. PoE-in. The directional antenna design means it benefits from accurate pointing towards the nearest mast, giving it an advantage over omnidirectional units at range.
MikroTik wAP LTE7 kit
An evolution of the popular wAP ac series – now with Cat 7 LTE, Wi-Fi 6, and an improved IP66 weatherproof enclosure. Compact wall-mount or pole-mount form factor. Fits the gap between a full industrial outdoor router and a basic consumer device: capable enough for a pop-up office, a construction site cabin, or an outdoor access point with cellular backhaul, at a price point that makes single-site deployments economical. Acts as a combined cellular router and wireless AP.
MikroTik LHG 4G kit
A high-gain directional outdoor 4G unit built around a 21 dBi grid antenna. Built for extreme rural locations where a standard outdoor router cannot hold a connection because the cell tower is simply too far away. Mount on a mast or rooftop, point at the nearest tower, and connect where mobile phones cannot. Cat 4, one Ethernet port, PoE powered. A narrow use case but there is no substitute when that use case applies.
MikroTik LtAP series
A weatherproof access point with a built-in cellular modem, three Mini-SIM slots for roaming management, RS232 serial port, USB, and a spare miniPCIe slot for a second LTE modem or a 5 GHz radio. Originally conceived for vehicle mounting but widely used in fixed outdoor positions – outdoor kiosks, traffic monitoring, and applications where the same unit needs to serve as both the cellular router and the local wireless AP.
Ubiquiti in outdoor cellular builds
Ubiquiti are best known for enterprise wireless, but their airMAX and UniFi product lines appear regularly in outdoor 5G builds – typically as the downstream wireless distribution layer behind an outdoor 5G router. The UniFi U6 Mesh and similar outdoor APs pair naturally with purpose-built outdoor cellular routers when local wireless coverage is needed across a car park, campus, or multi-building site. Ubiquiti’s outdoor PoE switching infrastructure also integrates cleanly with the PoE-out port on routers like the OTD140 and OTD500.
For installations using Ubiquiti’s UniFi management ecosystem, the practical architecture is: outdoor 5G router (Milesight UF51 or Teltonika OTD500) at the building exterior feeding a UniFi switch, with UniFi access points handling the indoor or outdoor wireless distribution. The cellular router handles the WAN; UniFi handles the LAN and Wi-Fi layer.
The Milesight UF51: the outdoor 5G router most specified for serious deployments
Milesight UF51
Ask cellular connectivity engineers across the UK what outdoor 5G router they keep specifying, and the same answer comes back: the Milesight UF51. It has earned that position through consistent real-world performance in deployments ranging from car parks and construction sites to SCADA substations and solar farms.
The UF51 is a cylindrical IP67 unit in polycarbonate and cast aluminium, 802.3at PoE powered from a single cable. Inside: a quad-core ARM Cortex-A55 at 2 GHz, 1 GB LPDDR4x RAM, 1 GB NAND flash, and a 5G NR SA/NSA modem with eight internal omnidirectional antennas covering all major UK 5G bands (N1, N3, N7, N28, N77, N78) plus full 4G LTE fallback. Peak downlink is 4.67 Gbps via dual carrier aggregation. Add built-in GPS, RS485 serial port, galvanically isolated digital inputs and outputs, and Node-RED running on-device for edge logic, and you have a unit that covers far more ground than a straightforward FWA box.
Two variants: the UF51-504AE (Ethernet only, 4.8W typical) for feeding a downstream switch or indoor AP, and the UF51-504AE-W4 (adds dual-band Wi-Fi 6 with 4×4 MIMO on both 2.4 GHz and 5 GHz, 9.9W typical) for when the outdoor unit also needs to provide local wireless coverage – a car park, a site entrance, a rooftop position serving an outdoor area. Fleet management, firmware updates, and remote configuration are handled through the Milesight Development Platform, the unified management layer for Milesight’s full IoT and cellular hardware range.
Approach 2: branded enclosure kits for indoor routers
Before purpose-built outdoor units became widely available – and still for integrators who prefer to choose router and enclosure independently – the standard approach has been to house a proven indoor industrial router in a weatherproof enclosure with integrated antennas. Two UK-relevant suppliers have built dedicated products around this concept.
QUWireless outdoor enclosure kits
- Compatible routers: Teltonika RUT200, RUT241, RUT901, RUT956, RUTX11, RUTX12, RUTX50, RUTM50
- Antenna: Integrated MIMO omni, matched per router model
- IP rating: IP67
- Power: PoE-in, single cable entry
- Mounting: Pole, wall, mast
- Variants: 4G and 5G; optional GPS patch antenna
Pre-cut and pre-drilled for specific Teltonika models – the router slides in, connections are made internally, and the unit is sealed. No external coax runs, no antenna matching guesswork. A popular choice for integrators already standardised on Teltonika hardware who want a clean outdoor solution without switching to a different router platform entirely.
GTT Wireless outdoor enclosure kits
- Compatible routers: Teltonika RUT901, RUT956, RUTX50, RUTC50; universal plate for Robustel, Digi and others
- Antenna: Integrated 2×2 MIMO omni covering 4G through 5G; dual-band Wi-Fi; optional GPS
- IP rating: IP67
- Power: PoE-in, single cable
- Variants: Outdoor omni kit (router-specific), universal omni kit, Raspberry Pi outdoor development kit
GTT take a broader approach than QUWireless – their universal enclosure accepts routers from multiple manufacturers, not just Teltonika. For integrators using Robustel, Digi, or other brands alongside Teltonika, the universal kit provides a consistent enclosure platform across different router choices. The Raspberry Pi development kit is useful for custom outdoor IoT applications where a cellular module on a Pi is the right architecture. See the IoTPortal GTT Wireless review for full detail.
Approach 3: indoor router in a generic weatherproof box
The lowest-cost option: any compact industrial router in an off-the-shelf IP65 or IP67 enclosure, with the router’s supplied stub antennas positioned inside the box. This works. For 4G Cat 1 monitoring applications with modest data requirements, it is often adequate. But the RF compromise is real – stub antennas are not designed to radiate through sealed enclosures.
If you use this approach: always choose polycarbonate or ABS plastic over metal (metal adds significant additional attenuation), and position the transparent face of the enclosure towards the cell tower. A clear polycarbonate lid in the right direction is measurably better than an all-metal box in the same location. For 5G FWA where throughput matters, this approach will disappoint and is not recommended.
PoE daisy-chaining: one cable, two powered devices
Getting more from a single Ethernet cable run
Some outdoor routers include both a PoE-in port (receiving power from the building) and a PoE-out port (delivering power to a second downstream device at the same mounting point). This is a feature that significantly changes what is possible with a single cable run up a pole or across a roof.
The architecture is straightforward: a single Cat6 cable runs from the PoE switch or injector inside the building up to the outdoor router. The router takes its power from that cable, and its second Ethernet port delivers 802.3af PoE to whatever device is mounted alongside it. That downstream device could be:
- A PoE-powered IP camera or PTZ camera – a single cable up the pole delivers both internet connectivity for the router and power for the camera
- An outdoor Wi-Fi access point – extending wireless coverage from the same pole without a separate power feed
- A LoRaWAN gateway or other IoT sensor hub requiring a network connection
- A PoE-powered environmental or industrial sensor
- A second outdoor access point in a chained configuration
The Teltonika OTD140 and OTD500 are the clearest examples of this in practice. Both include a PoE-in port (802.3af/at) and a PoE-out port (802.3af). In a car park CCTV installation, for instance, the OTD500 mounts at the top of a lighting column: one Cat6 in from the base, 5G connectivity to the internet, and a PoE-out cable down to a camera bracket 30 cm lower on the same column. Two powered devices, one cable, no cable tray, no additional power feed at the column.
What to check: the PoE-out budget on these routers is typically 802.3af (up to 15.4W), which covers most IP cameras and compact outdoor APs but not higher-power 802.3at devices. Check the power draw of the downstream device before specifying. Also confirm that the PoE injector or switch feeding the router is 802.3at (PoE+, 30W) to cover both the router and the PoE-out budget simultaneously.
Powering outdoor routers: passive PoE, active PoE, and what to buy
Active PoE (802.3af / 802.3at)
Active PoE is the IEEE standard. An 802.3af switch or injector negotiates with the powered device before applying power. 802.3af delivers up to 15.4W; 802.3at (PoE+) delivers up to 30W. Most purpose-built outdoor routers – the Milesight UF51, Teltonika OTD500, Zyxel NR7302 – are 802.3at PoE PD devices. If you have an existing PoE+ switch, the outdoor router plugs straight in.
Passive PoE
Passive PoE applies a fixed voltage without negotiation. Many compact indoor industrial routers in weatherproof enclosures accept passive PoE as an alternative to their DC power input. A passive injector combines mains and Ethernet data signals and delivers both over a single Cat5e/Cat6 cable. Check the required voltage for your specific router before buying a passive injector – typically 12V, 18V, or 24V depending on the model. Most Teltonika RUT models accept 9-30V DC.
If you have an active PoE switch and need passive PoE output
A PoE converter bridges the two standards. This Ubiquiti active PoE to passive PoE converter takes standard 802.3af/at input and outputs a fixed passive voltage – widely used for exactly this scenario, and compatible with most passive PoE industrial router installations.
Out-of-band management: the use case people forget about
Reaching your network when the primary link is down
Out-of-band management – OOB or OOBM – is the use of a secondary, independent network path to access and manage infrastructure when the primary connection is unavailable. The scenario is familiar to anyone who manages remote sites: a leased line or fibre link goes down, and suddenly you cannot reach the router to diagnose it, because the router is what has gone down. If a cellular router provides an independent management path into the same location, you can still SSH in, push a config fix, reboot a device, or check whether the problem is at your site or the ISP’s end – without leaving the office.
The cellular link is independent of the primary WAN at every level: different physical medium, different infrastructure, different last-mile provider. It does not share the same trench, the same exchange building, or the same ISP routing chain.
Why outdoor routers are particularly suited to OOB:
- An outdoor cellular router on the building exterior is physically separate from the indoor switching and routing equipment it is managing. If the comms room loses power or an indoor device fails, the outdoor router on a UPS-backed PoE switch can still provide access.
- Dual SIM (OTD500, UF51) adds SIM-level resilience on top of the physical independence – if one mobile operator has an outage, the OOB link stays up on the second SIM.
- Industrial outdoor routers with RS232 or RS485 serial ports (the Teltonika RUT956, OTD140, and Milesight UF51 all have serial) can connect directly to the console port of a primary router or switch, giving engineers console-level access to a failed device over cellular even when IP networking on that device is not functional.
For enterprise IT environments that need a purpose-built OOB platform rather than a general-purpose industrial router, Opengear (a Digi International company) produce dedicated console servers with integrated 5G cellular – the CM8100-10G-5G being the current flagship. These provide managed serial console access, power control, and zero-touch provisioning across a fleet of network devices, with cellular as the out-of-band path. Cellular OOB is also built into the management proposition of Ericsson Cradlepoint‘s NetCloud platform and Peplink‘s InTouch remote management system.
Rapid deployment: connectivity in minutes, not days
Not every outdoor cellular installation is permanent. Utility engineers attending a major incident, IT teams standing up a temporary site office, construction project managers on a plot with no infrastructure, emergency services at an unplanned location – none of these can wait for a planned installation with cable runs and switched PoE. The rapid-deployment category exists for this: pre-configured, self-contained 5G connectivity that is operational within minutes of arriving on site.
The concept is straightforward. Take a 5G router, combine it with a pre-provisioned SIM and VPN configuration, add a power source that does not require mains infrastructure, and house it in something that can be carried and deployed by one person. The sophistication varies by price point and application, but the underlying principle is the same: power on, connect, done – with no on-site configuration required.
Several large enterprise networking vendors have formalised this as a product category. Ericsson Cradlepoint is the most enterprise-credible name in this space. Their NetCloud platform – the cloud management layer across the full Cradlepoint hardware range – is designed around zero-touch provisioning: a device pre-registered in NetCloud connects automatically when powered up, with no on-site configuration required. BT Business uses Cradlepoint as its primary hardware partner for its 5G Fixed Wireless Access solution, deployed across 33 countries – the BT Business overview of the Cradlepoint 5G FWA partnership gives a clear picture of how enterprise-scale rapid 5G deployment works in practice.
Peplink take a similar approach with SpeedFusion and InControl 2. Their rapid-deployment line includes multi-cellular bonding routers that aggregate multiple 5G and 4G connections simultaneously – useful when peak reliability matters more than raw throughput from a single link. Their InTouch platform adds out-of-band management capability on top of the primary connectivity. Digi International (which also owns Opengear) serve the industrial and utility rapid-deployment market with ruggedised hardware managed through Digi Remote Manager – the IX40 and IX25 series are common in utilities, transport, and government deployments.
Below the enterprise tier, a growing number of UK integrators build bespoke rapid-deployment kits around standard outdoor 5G routers – typically a Milesight UF51 or Teltonika OTD500, a PoE injector, a battery pack with suitable runtime, and a pole-mount bracket, all housed in a weatherproof transit case. These do not appear in product catalogues but they are the practical solution for utilities, events teams, and construction project managers who want rapid connectivity without enterprise-level procurement. The key principle is identical: pre-configure everything before it leaves the office so the person on site has nothing to set up.
eSIM and outdoor routers: SIM switching without a ladder
SGP.22, SGP.32, and what eUICC actually means in practice
Swapping a physical SIM in an outdoor router mounted on a wall or pole means getting a ladder out. For one site, a minor inconvenience. For a fleet of 50 outdoor routers across 50 sites, a meaningful cost. The eUICC (embedded Universal Integrated Circuit Card) standard removes this by allowing the SIM profile to be changed remotely, over the air, without physical access to the device.
There are two GSMA eSIM specifications relevant to outdoor routers, and the distinction matters:
SGP.22 is the consumer eSIM standard – the same specification used in smartphones. It assumes a user is present to initiate profile changes, typically by scanning a QR code or using an app. Most outdoor routers that describe themselves as “eSIM-equipped” – including the Teltonika OTD500, Zyxel NR7302, and MikroTik ATL 5G R16 – implement SGP.22. In practice, for a managed fleet of outdoor routers, the operator can initiate profile changes remotely through the router’s management platform (Teltonika RMS, for example), which overrides the consumer assumption of a user being present. SGP.22 with a cloud management platform delivers the key practical benefit – remote SIM switching without a site visit – even though it was not designed specifically for this use case.
SGP.32 is the GSMA’s purpose-built IoT eSIM standard, published in 2023. It is designed specifically for headless, unattended devices – no user interface, no QR code, no assumption of anyone being present. Profile changes are initiated server-side by an eIM (eUICC IoT Manager), not by a user action. SGP.32 also introduces CoAP over UDP transport for constrained devices, and removes the HTTPS dependency that makes SGP.22 impractical for low-power NB-IoT sensors. For outdoor router fleets, SGP.32 means profile provisioning and switching is handled entirely at the infrastructure level – cleaner, more scalable, and designed to work at the scale of thousands of devices. Commercial SGP.32 deployments are live as of 2026, with Telenor IoT among the most advanced. For the full technical picture on SGP.32 architecture, hardware support, and UK network availability, see sgp32.co.uk. For the broader eUICC standard context, see euicc.co.uk.
What this means for an outdoor router deployment today: if you are specifying a fleet of outdoor routers and SIM management at scale is a requirement, choose units with eSIM support and confirm whether they implement SGP.22 (most current hardware) or SGP.32 (emerging). Either removes the need to visit each site to swap a physical SIM. SGP.32 is the cleaner long-term architecture as the hardware and network support matures.
5G FWA: the biggest outdoor router application
Fixed wireless access is the use case that has driven most of the outdoor 5G router market in the last three years. The premise: a 5G connection delivered to a building exterior replaces a fixed broadband line. No trenching, no waiting for fibre build, no landlord permission for ducting. The outdoor 5G router mounts on wall or pole, connects to 5G, and delivers gigabit-class internet inside over a single Ethernet cable.
For UK businesses in areas with strong 5G coverage, this is a genuinely viable alternative to leased lines and FTTC. The key considerations are cell tower proximity and line of sight (both matter more for 5G at 3.5 GHz than for 4G at 800 MHz), operator coverage at the specific postcode, and whether the application needs a fixed IP address. 5G FWA typically uses unlimited data SIMs – data volumes for business premises are in the terabyte range, beyond the practical range of most IoT SIM tariffs. For a full technical and commercial breakdown of 5G FWA in the UK, see 5gfwa.co.uk.
Indoor router vs outdoor router: the honest comparison
| Factor | Indoor router + outdoor antenna | Purpose-built outdoor unit |
|---|---|---|
| Installation complexity | Higher – 2 to 4 coax runs, weatherproof glands, cable management | Lower – one Cat6 through wall, one hole |
| RF performance | Reduced by insertion loss in cable (~0.5-1 dB per metre at 4G; more at 5G frequencies) | Maximum – antenna in free air, zero cable loss |
| 5G MIMO | 4 cables for 4×4 MIMO – expensive and messy to route | 8 integrated antennas, no external cabling |
| SIM access | Easy – SIM slots are indoors, accessible without climbing | Requires dismounting unless eSIM equipped |
| Indoor Wi-Fi | Good – router is indoors, signal not attenuated through walls | Requires downstream indoor AP via Ethernet |
| Outdoor Wi-Fi | Attenuated through building fabric | Excellent on Wi-Fi variant (UF51-W4, wAP LTE7) |
| PoE daisy-chain | Not applicable | Available on OTD140, OTD500 – powers a second device from same cable |
| Out-of-band management | Cellular router provides OOB path regardless of indoor position | Optimal – physically and electrically separate from primary WAN |
| Power | Mains adapter at indoor location | Single PoE cable from any 802.3at switch or injector |
| Best for | Existing indoor deployments, when indoor Wi-Fi coverage is the priority | New builds, 5G FWA, large sites, any deployment where RF performance matters |
Real-world applications
5G fixed wireless access
The largest growth application. An outdoor 5G router on a building exterior or pole delivers gigabit-class internet to an entire premises over a single PoE cable. Replaces FTTC or FTTP where fibre is unavailable or uneconomic. Most effective with clear line of sight to a 5G mast at Band 77 or Band 78.
Car parks and ticketing infrastructure
A classic case for PoE daisy-chaining. An outdoor 5G router at the top of a lighting column – one Cat6 cable in from the building, PoE-out to a camera on the same column. The router handles the WAN, the existing indoor switch handles the LAN, and the camera has both power and connectivity from a single run of cable.
Out-of-band management
An outdoor cellular router on the building exterior, physically separate from the primary WAN equipment inside, provides an independent management path for network engineers. When the primary internet connection fails – ISP outage, fibre cut, misconfigured route – the OOB cellular link stays up. Engineers reach the affected equipment and restore service without a site visit.
Construction sites and temporary offices
Sites move; permanent infrastructure does not make economic sense. An outdoor 5G router on a site hoarding or Portakabin roof delivers internet to the site office, security systems, and connected plant monitoring. For temporary deployments, a pre-configured unit in a transit case with a battery pack is operational in minutes.
Industrial and SCADA sites
Water pump stations, substations, solar farms, and pipeline outstations frequently require outdoor cellular installations. The UF51 and OTD140 both include RS485 serial ports for direct connection to SCADA RTUs and PLCs without a separate converter. See the IoTPortal guide to remote SCADA access for the full architecture.
CCTV and security systems
Deployable CCTV towers and fixed outdoor camera systems use outdoor routers as the cellular backhaul. On units with PoE-out (OTD140, OTD500), the router powers a downstream PoE camera directly from the same cable that powers the router – one Cat6 up the pole, two powered and connected devices at the top.
SIM cards for outdoor router deployments
5G FWA – premises broadband
A single-network unlimited data SIM from EE, Vodafone, O2, or Three. 5G FWA prioritises throughput. A second SIM from a different operator in the router’s second slot handles failover. Identify the operator with the strongest 5G signal at the specific postcode before buying.
IoT, industrial and OOB
A multi-network IoT SIM roaming across all four UK operators. Coverage reliability matters more than peak throughput for SCADA, monitoring, and out-of-band management. Fixed IP is often required. IoTSims.co.uk provides multi-network IoT SIMs with fixed IP options suited to outdoor industrial deployments.
Mobile and multi-site deployments
For outdoor routers that move between locations – construction sites, events, rapid-deployment kits – a roaming SIM across multiple operators is the practical answer. RoamingSIM.co.uk covers UK multi-network roaming SIM options with data management portals for fleet use.
For a full explanation of IoT SIM options, multi-network SIMs, fixed IP, and private APN, see the IoTPortal IoT SIM guide and the IoT SIM card directory.
What to check before buying an outdoor router
- IP rating: IP67 for fully exposed positions; IP55 acceptable for sheltered mounting under eaves or inside vented cabinets. Do not use IP44 or below outdoors in UK weather.
- PoE standard: confirm the router is a PoE PD and the wattage required. 802.3at (30W) is most common. Match to your switch or injector output, particularly if using PoE-out to power a downstream device.
- PoE-out: if you need to power a second device at the same mounting point, confirm the router has a PoE-out port and check its output wattage (typically 802.3af, 15.4W maximum).
- 5G bands: for UK deployments, N77 and N78 (3.5 GHz) are the primary 5G bands. N28 (700 MHz) is the rural coverage band. Confirm the router covers all three.
- Dual SIM: strongly recommended for any unattended outdoor deployment. Single SIM is a single point of failure for OOB and industrial applications.
- eSIM: for large fleets or difficult-to-access positions, eSIM (SGP.22 or SGP.32) allows remote profile switching without a site visit. Check which standard the router implements and confirm compatibility with your management platform.
- Serial port: RS485 is needed for direct SCADA and industrial device connection. Not all outdoor routers have this – the UF51 and OTD140 do; the Zyxel NR7302 does not.
- Lightning protection: mandatory for rooftop and pole-mounted installations. The OTD500 and NR7302 both include 6kV integrated lightning suppression.
- OOB management capability: confirm the router supports your chosen management platform over cellular independently of the primary WAN – Teltonika RMS, Milesight Development Platform, RouterOS, or a third-party console server platform.
