NB-IoT/LTE-M Dual-mode Communication Wireless I/O Module

Deeper and Wider Network Coverage

The coverage of NB-IoT is theoretically 20 dB stronger than traditional GPRS and LTE, offering stable reception quality

Secure Encrypted Transmission

Follows the security approaches of 4G LTE, ensuring that data is transmitted safely during communication

Lower Power Consumption​

The operational life of nodes is extended by low frequency, low power consumption, and low chip complexity designs

Using NB-IoT, a new wireless communication technology designated as an international standard under the 3rd Generation Partnership Project (3GPP), AD-WISE-4671 offers data transmission rates around 100 kbps in NB-IoT mode. NB-IoT is up to 20dB stronger than traditional GPRS and LTE, providing stable reception quality even with buried lines or when underground. Both NB-IoT and LTE-M feature long distance transmission across wide area networks—making AD-WISE-4671 an ideal edge solution for applications performing remote transmission.

AD-WISE-4471/WISE-4671 follows MQTT's publish and subscribe messaging model which is ideal for low bandwidth, high latency, and data limits. Additionally, as an IoT device, AD-WISE-4471/WISE-4671 also supports lightweight protocols such as CoAP, which are suitable for small devices that are unable to communicate efficiently with limited resources.

As MQTT and CoAP are popular standards in the market, the data format can raise concern over messaging protocols. Accordingly, AD-WISE-4471/WISE-4671 also supports the LwM2M protocol which has the management interface built on top of CoAP to enable device management operations.

There is also the official publication of OMA LwM2M2 Objects and Resources to alleviate data inter-compatibility concerns. LwM2M is a protocol offering flexible and scalable device management with improved time to the market; especially for low power devices with constrained processing and storage capabilities.
