Cat-1 vs LTE-M
TL;DR
Cat-1 wins if you need more bandwidth (CCTV, POS, gateways) or your target coverage is international without LTE-M guarantee. LTE-M wins if battery or deep indoor coverage is the priority and you can live with its bandwidth limits.
Comparison table
| Criterion | LTE Cat-1 | LTE-M |
|---|---|---|
| Throughput | Up to 10 Mbps DL | Up to 1 Mbps DL |
| Latency | <100 ms | 100-500 ms |
| PSM power | Higher (no full LPWA) | Much lower |
| Indoor coverage | Standard LTE | +15 dB over LTE |
| Global support | Universal where 4G exists | Only where the carrier deploys it |
| Module cost | 8-15 EUR (Cat-1 bis very cheap) | Similar or slightly higher |
When Cat-1 / Cat-1 bis is the right call
Any product needing bandwidth or guaranteed reach on standard LTE worldwide. The pragmatic 3G replacement.
- ·POS terminals
- ·Industrial 4G routers
- ·Low-res IP cameras
- ·Multi-protocol gateways
- ·Tracking with short video recording
When LTE-M is the right call
Battery-powered devices or those needing coverage in basements where standard LTE drops. Wearables, portable alarms, and critical sensors.
- ·Medical wearables
- ·Battery-powered portable alarms
- ·Multi-year-life trackers
- ·Sensors in weak-coverage areas
Verdict
In 2026, Cat-1 bis is the default for general-purpose IoT (3G replacement, POS, gateways). LTE-M is reserved for real LPWA cases or essential deep coverage.
FAQ
Does Cat-1 work as a 2G/3G replacement?+
Yes, the natural migration for general-purpose IoT when NB-IoT/LTE-M do not fit or are not deployed.
Are there dual Cat-1 + LTE-M modems?+
Yes; several vendors have Cat-1 with LTE-M fallback. Useful for mixed international fleets.
More comparisons
LTE-M vs NB-IoT
LTE-M wins when the device moves or needs low latency (asset trackers, alarms, wearables). NB-IoT wins when the device is static and needs multi-year battery with deep indoor coverage (meters, parking, sensors). When in doubt, check real coverage at your deployment country before standard specs.
eSIM (eUICC) vs SIM tradicional
eSIM (eUICC) wins on flexibility and long-term cost, especially when the product ships across countries. Traditional SIM still wins on simplicity and upfront price when the carrier will not change and volumes are low.
APN privado vs VPN
Private APN controls where device traffic exits and which IPs they get. VPN encrypts the path between that exit point and your data center. The norm in serious IoT: both together.
