5G and IoT: what actually matters
Short answer
5G brings three useful things to IoT: RedCap (cheaper 5G devices with LTE Cat-4-like capabilities), network slicing (per-segment QoS guarantees), and URLLC (low, reliable latency for robotics and automotive). Massive IoT (mMTC) is still arriving; meanwhile, LTE-M/NB-IoT dominate.
5G RedCap: pragmatic 5G IoT
RedCap (Reduced Capability) is the mid-range 5G IoT profile: ~150 Mbps, reasonable module cost, lower power than high-end 5G. Replaces LTE Cat-4 in industrial gateways, cameras, and wearables. Commercially available 2025-2026 in Spain.
Network slicing
Lets you reserve a 5G 'slice' with contractually guaranteed latency, bandwidth, and availability. Useful in critical health, factory automation, and sensitive logistics. Premium cost and only where it's worth measuring.
URLLC for critical control
Ultra-Reliable Low Latency: <10 ms and extremely low loss. Collaborative robotics, autonomous vehicles, production automation. Only on 5G Standalone; infrastructure still growing.
- RedCap: gateways, cameras, wearables
- Slicing: contractual QoS
- URLLC: critical control
- mMTC: coming, slowly
- LTE-M/NB-IoT remain the base

Frequently asked questions
Should I jump from LTE-M to 5G now?+
In 2026, only if you need high throughput or URLLC. For telemetry and metering, LTE-M/NB-IoT remain cheaper and more efficient for several years.
Are 5G modules affordable yet?+
RedCap is cutting prices: €25-40/module in 2026 vs €60-100 for 5G sub-6. By 2027-2028, RedCap should displace Cat-4/Cat-6.
Will 5G sunset 4G?+
Not before 2030 in Europe. LTE-M lives in the 4G bands and will stay as long as that spectrum is alive.
