The Weightless SIG has announced the deployment of Weightless-N Smart City networks from Nwave Technologies across Copenhagen and the south of Denmark around the city of Esbjerg. Copenhagen is Denmark’s capital and largest city and Esbjerg the second largest port city and a leading European offshore energy industry center.

    Nwave Technologies is collaborating with leading Accelerator organizations, Accelerace Management and Next Step City, in Denmark to roll out the country’s first Smart City networks. This announcement follows the recent publication of version 1.0 of the new Weightless-N open standard based on the low power wide area star network (LPWAN) architecture and the subsequent Weightless network deployment across London, England.

    Operating in sub-1GHz, license-exempt ISM spectrum using ultra narrow band (UNB) technology, Weightless-N offers best-in-class signal propagation characteristics, leading to excellent range of several kilometers, even in challenging urban environments. Very low power consumption provides for exceptionally long battery life measured in years from small conventional cells, and leading edge innovation in design minimizes both terminal hardware and network costs.

    Weightless-N is designed around a differential binary phase shift keying (DBPSK) digital modulation scheme to transmit within narrow frequency bands using a frequency hopping algorithm for interference mitigation and enhanced security. It provides for encryption and implicit authentication using a shared secret key regime to encode transmitted information via a 128 bit AES algorithm. The technology supports mobility with the network automatically routing terminal messages to the correct destination. Multiple networks, typically operated by different companies, are enabled and can be co-located. Each base station queries a central database to determine which network the terminal is registered to in order to decode and route data accordingly. The complete specification is available to Weightless SIG Members for immediate download from the organization’s website.
