Wireless remote transmission NB-IoT module

Product ID.：WL335

Communication mode：NB-IoT

The WL335 module is a functional remote transmission module based on NB-IoT. Combined with specific industry applications, users can complete the process of developing mass production deployment in the shortest time without concern for the specific protocols and applications of NB-IoT. Based on the established server IP, the application layer data transparent interaction with the remote data center can be realized. This module is an excellent choice for low cost, low power, high performance, long range communication solutions for AMR/AMI/IoT applications.

  • Main Functions
  • Technical Parameters
  • Anti-jamming function. The design adopts low noise, high sensitivity receiver and advanced data encryption and decryption technology, which has strong anti-interference ability and ensures high communication speed.
  • Wireless communication environment analysis function. The RSSI of the inter-node communication link can be queried by instructions to identify the current communication quality.
  • Support for user device access. The system separately allocates an UN channel for user equipment communication, extending the interaction with the user.
  • Parameter configuration. Parametric read and write access to distributed terminals is possible.
