EWM-NB157S01E designed to communicate with Mobile Network Operator infrastructure equipment using the 3GPP NB-IoT radio protocol.
- Integrated serial interfaces: UART
- Up to +20 dB extended coverage compared to GPRS (164dB Maximum Coupling Loss),equivalent to a 179dB link budget
- support 3GPP Rel.14 NB-IoT air interfaces and protocols
- Support Band 1,3,5,8
The system is designed to support a very large number of connected terminal devices (up to 55,000 per cell), and supports adaptive modulation coding and spreading schemes to enable a wide range of trade-offs between coverage and bit rate.
