5G routers for business, IoT and industrial sites

A 5G router connects a site to the mobile network and shares that connection with everything on it. These guides explain how 5G routers work, which type suits which job, and how to get the antennas, SIMs and failover right on UK networks.

What is a 5G router?

Short answer. A 5G router is a router with a 5G cellular modem built in. It takes a SIM or eSIM, attaches to the nearest suitable mast and shares that connection over Ethernet, Wi-Fi or industrial interfaces such as RS485.

Business and industrial 5G routers are a different class of device from the white box a network sends out with home broadband. They have external antenna connectors, a firewall and VPN you can configure, failover between two SIMs or a fixed line, and remote management for whole fleets. Most are unlocked, so the router and the SIM are chosen separately.

Nearly every 5G router also works on 4G and drops back automatically where 5G is weak. That matters outside towns, where a router may spend much of its life on 4G or on 5G running in a low band. Read the complete 5G router guide for the full picture.

How a 5G router connects a site

How a 5G router connects a siteYour equipment connects to a 5G router, which uses antennas to reach the nearest 5G mast. The operator core checks the SIM and assigns an IP address, then traffic reaches the internet, a VPN or a private APN.AT THE SITEYour equipmentPCs, tills, CCTVPLCs and sensors5G routerRouting, firewallVPN and failoverAntennasFour for 4x4 MIMOoften externalMOBILE NETWORKRADIO LINKN78, LOW BAND 5G OR 4G5G mastNearest suitablecell siteOperator coreChecks the SIMassigns an IP addressInternet or VPNCloud, head officeor a private APN
The router sits between your equipment and the mobile network. Most performance problems are at the antennas or in the choice of SIM, not inside the router.

Types of 5G router and where each fits

All 20 guides

The modem inside many 5G routers is similar. The case, interfaces, power input and software are what make one suited to an office and another to a cabinet on a pumping station.

Business and office 5G routers

Main broadband or backup for offices, shops and branches, with Wi-Fi, a WAN port for fibre and a firewall you can configure.

Typical use · Offices, retail, failover

Industrial 5G routers

DIN rail mounting, wide DC input and an extended temperature range for cabinets, substations and plant rooms that run unattended.

Typical use · SCADA, utilities, telemetry

Outdoor 5G routers and CPE

Weatherproof units fixed to a wall or mast, close to the signal, fed by a single PoE cable from inside the building.

Typical use · Rural sites, FWA, farms

IoT and RedCap 5G routers

Compact gateways for connected equipment, including RedCap models that trade peak speed for lower cost and power draw.

Typical use · EV charging, signage, vending

Dual SIM and dual modem 5G routers

Two SIMs, or two complete modems, so a site stays online when one network has a fault or a coverage gap.

Typical use · High availability, payments

5G routers for CCTV

Upload headroom, remote access and local recording for cameras on building sites, car parks and farms.

Typical use · Security, remote video

How to choose a 5G router

Full buying checklist

Work through it in this order and most of the decisions make themselves. Comparing router models comes last, not first.

  1. Check real coverage

    Test at the site with a device on the networks you are considering. Coverage maps are optimistic, especially indoors and for 5G in the n78 band.

  2. Plan the antennas

    Decide where the router and antennas will go. Four connected antennas for 4x4 MIMO on a short run of good cable usually beat a more expensive router.

  3. Settle the SIM and IP

    Work out what needs to reach the site. Inbound remote access needs a public IP SIM, a private APN or an outbound VPN.

  4. Decide on resilience

    How much downtime you can accept decides single SIM, dual SIM or dual modem, and whether 5G backs up a fixed line.

  5. Pick the hardware class

    Office, industrial or outdoor. Power input, mounting and temperature range rule out most of the market quickly.

  6. Compare models last

    Only then compare specific routers, their remote management platform and how long the vendor keeps shipping firmware.

Where UK 5G routers get their signal

4G vs 5G routers
Where UK mobile broadband sits in the spectrum A frequency scale from 600 MHz to 4 GHz. Low bands at 700, 800 and 900 MHz give reach. Mid bands at 1800, 2100 and 2600 MHz carry most 4G. The n78 band from 3.4 to 3.8 GHz carries most UK 5G capacity. Main 5G bands Bands mostly used for 4G 700 800 900 1800 2100 2600 n78 600 MHz 1 GHz 2 GHz 3 GHz 4 GHz Low band: reach and getting through walls Mid band: capacity and speed
Most UK 5G capacity sits in n78 at 3.4 to 3.8 GHz, which is fast but short-ranged and struggles through walls. Operators also run 5G in some lower bands, which is one reason a 5G router can show a 5G connection and still perform like 4G.

5G router questions

More in the complete guide

What is the best 5G router for business?

There is no single best model. The right 5G router depends on coverage at the site, where it will be installed, what needs remote access and how much downtime you can accept. Settle those first, then compare routers with four external antenna connectors, dual SIM, a VPN you can configure and a remote management platform.

Are 5G routers unlocked?

Business and industrial 5G routers almost always are, so you can use any compatible SIM and change network if coverage is poor at a site. Routers supplied with home broadband contracts are usually locked to that network.

What is the difference between a 5G router and 5G CPE?

CPE, or customer premises equipment, is the general term for the box that delivers a service at a site. In 5G it usually means an indoor or outdoor unit built mainly for fixed wireless access. A 5G router normally adds routing, firewall, VPN and failover features. Many products are both.

Can a 5G router work without a SIM card?

It needs a mobile subscription, but that does not have to be a plastic SIM. Routers with an eSIM, or eUICC, can download operator profiles remotely, which suits fleets where swapping SIMs would mean a site visit.

Do 5G routers need an external antenna?

Not always, but often. A router near a window in good coverage may be fine with its own antennas. One in a cabinet, a basement or a steel-framed building usually needs external antennas to get anywhere near its potential.

Is a 5G router worth it over a 4G router?

If you move video, replace a fixed line or serve many users, usually yes. For small amounts of telemetry, a 4G Cat 1 or LTE-M device is cheaper and uses less power. A 5G router also works on 4G, which helps the hardware stay useful for longer.
