Comparison of 4G Cat.1 and NB-IoT Technologies:
| Communication function | 4G Cat.1 | NB-IoT |
| Band bandwidth | 20MHz | 200KHz |
| Peak speed(ULIDL) | 10Mbps/5Mbps | 126kbps/158.5kbps |
| Coverage enhancement | +0 dB vs GSM(similar to GSM) | +20 dB vs GSM(4 times stronger than GSM) |
| Delay | <100ms,real-time | Second level |
| Mobility | Full mode switching | Cell reselection |
| Voice | VOLTE/CSFB | Not supported |
| Low power capabity | Support DRXeDRX/PSM | Suppot DRXeDRX/PSM |
| RF antenna | Dual/single anten optional | Single antenna |
Summary:in terms of communication capability,Cat.1 has stronger ability and communication stability performance compared to NB-IoT based on mature LTE networks.In typical application scenarios,the power consumption of Cat.1 module products is close to NB-lT.
