5G Connectivity for Transport and Passenger Wi-Fi
Passenger expectations for on-vehicle Wi-Fi have risen substantially. Rail passengers in particular expect connectivity comparable to their home broadband. 5G provides the throughput needed to serve a full complement of passengers simultaneously – video streaming, video calls, and remote working – while also supporting the operational applications the vehicle requires.
SimWise supplies 5G routers, multi-network IoT SIM cards, and vehicle-rated antennas for the transport sector.
Passenger Wi-Fi on Coaches and Buses
Coach operators and bus companies offering passenger Wi-Fi need a 5G router that maintains connectivity while moving across a wide geographic area. A multi-network SIM ensures the router always connects to the best available network, providing continuous passenger Wi-Fi coverage across the route rather than dropping in lower-coverage areas.

Rail and Light Rail
Rail connectivity requirements include passenger Wi-Fi, CCTV transmission, real-time passenger information systems, and telematics. 5G routers with high-gain directional antennas can maintain connectivity at line speeds where standard router antennas struggle. Multi-network SIM cards are essential for routes that traverse areas with varying network coverage.
Real-Time Vehicle Telematics
Fleet operators use cellular connectivity for real-time vehicle tracking, driver behaviour monitoring, remote diagnostics, and tachograph data upload. 5G provides the bandwidth for richer data streams and faster upload of stored data when the vehicle is in coverage.

Multi-Network SIMs for UK-Wide Transport Routes
A coach or lorry travelling from London to Edinburgh crosses areas where EE, Vodafone, O2, and Three each have different coverage profiles. A multi-network IoT SIM card that automatically roams to the strongest available network provides the most consistent connectivity across the full route, rather than depending on a single carrier that may have gaps in rural parts of the route.
External Antennas: Do You Need One?
Every 4G and 5G router ships with stub antennas attached to the ports on the casing. In many installations these are perfectly adequate. In others – particularly inside metal-framed buildings, below ground level, or in rural areas far from the nearest mast – an external antenna can make a significant and measurable difference to both signal quality and sustained throughput.
Before purchasing an external antenna, we recommend working through a structured test process:
- Baseline test with supplied antennas in the intended location. Install the router where it will live in normal operation. Note the RSRP value from the router diagnostic page – this is a more reliable indicator than signal bars. Run a speed test and record the results.
- Try different positions within the same space. Cellular signal varies considerably within a single room. A window-mounted location can outperform a cabinet in the centre of the same space by 10-15 dB. Try several positions before concluding signal is poor.
- Test outdoors on a dry day. Take the router outside – clear of the building envelope – and run the same tests. Building fabric, particularly reinforced concrete, metal cladding, and low-emissivity glass, can attenuate signal by 20 dB or more. If outdoor results are substantially better, an externally-mounted antenna is the right solution.
- Test each network in turn. If you have a multi-network IoT SIM, lock the router to each available network and test each one. Coverage and performance vary significantly by network at any given location. EE frequently outperforms in rural areas; Three tends to be strongest in urban environments.
- Consider a directional antenna if signal is marginal. An omni-directional antenna captures signal from all directions but lacks gain. If you know the direction of the nearest mast, a directional or panel antenna aimed at the mast can provide 5-9 dBi additional gain over a standard stub – the equivalent of moving the router significantly closer to the mast.
Antenna Connection Note
Most 4G and 5G routers use SMA or TS9 connectors. Check your router specification before ordering an antenna and cable. For cable runs over five metres, use low-loss coaxial cable – standard RG58 introduces approximately 1.5 dB of loss per metre at LTE frequencies, which can negate the benefit of the antenna. Speak to SimWise before specifying a long cable run. Browse our antenna range.
