nWave
nWave is one of several open standards for low power WANs( LPWAN) that transmits in the sub- GHz frequencies of 433 MHz and 868 MHz( EU). As with SigFox and Weightless, the transmission is ultra-narrowband in the N version.
Ultra-narrowband transmission has the advantage of low power consumption compared to other modulation methods and the associated extension of battery life. This can easily reach 10 years. Like the other LPWANs, nWave is designed for the Internet of Things( IoT) and Machine to Machine Communication( M2M).
nWave formed the template for Weightless-N. It was developed by the Danish company of the same name and is being promoted and developed by the Special Interest Group( SIG). The company offers radio modules, universal modems and transceivers for the base station. The transmit power of the radio modules ranges from 25 mW to 100 mW. With nWave, distances between 5 km and 10 km can be bridged in built-up areas, while in rural areas the distance is considerably greater. To ensure that the networks consume as little energy as possible, the data rates are also extremely low. The data rate for the uplink, for example, is 100 bit/s.
