5G Connectivity for Manufacturing and Industry 4.0
5G's combination of high throughput, low latency, and high device density makes it a natural fit for smart manufacturing environments. Where Wi-Fi suffers from interference in harsh industrial environments and wired Ethernet is impractical for mobile equipment and robot cells, 5G provides a reliable, managed wireless connectivity layer for manufacturing applications.
SimWise supplies 5G routers and SIM cards for manufacturing facilities requiring cellular connectivity for production monitoring, machine telemetry, and Industry 4.0 applications.
Applications in Manufacturing
Production Monitoring and OEE
Overall Equipment Effectiveness (OEE) platforms collect data from production equipment in real time. 5G routers connecting machinery to cloud-based OEE systems provide reliable, low-latency data transfer without the limitations of factory Wi-Fi in metallic environments.
Machine Telemetry and Predictive Maintenance
Vibration sensors, temperature monitors, and power quality meters on production equipment communicate continuous telemetry over cellular connections. 5G provides the bandwidth and low latency required for high-frequency sensor data from multiple machines simultaneously.
Connected Workers and Wearables
Industrial wearables – smart glasses, body-worn cameras, and biometric safety monitors – need reliable wireless connectivity throughout a factory floor. 5G provides the device density and bandwidth that Wi-Fi struggles to deliver in complex industrial environments.
Private 5G vs Public 5G for Manufacturing
For large manufacturing facilities, a private 5G network (using CBRS or shared spectrum) may be the long-term solution. For facilities that need cellular connectivity now, public 5G from the UK networks via a 5G router is the practical near-term approach. SimWise can advise on both options and the transition path from public to private 5G as coverage and hardware matures.
ERP and MES Connectivity
Enterprise Resource Planning (ERP) and Manufacturing Execution Systems (MES) require reliable, always-on connectivity for production floor terminals, barcode scanners, and handheld devices. A 5G router with a business SIM card provides the backbone connectivity for these systems in areas where Wi-Fi coverage is inconsistent.
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.
