RFWavenis Technology: Features and Applications
Advertisement
This article explores the fundamentals of Wavenis technology, covering its key features and common applications within the realms of M2M (Machine-to-Machine) and the Internet of Things (IoT).
Wavenis is a wireless technology that was developed by Coronis back in 2000. It’s specifically designed for ultra-low power consumption and long-range Wireless Sensor Networks (WSNs).
The technology has gained popularity through the efforts of the Wavenis Open Standard Alliance. It finds numerous applications in the smart grid sector, including telemetry, automatic meter reading, and general utility metering.
Wavenis operates in the ISM (Industrial, Scientific and Medical) band, utilizing different frequencies depending on the region. These include 433MHz (China), 868MHz (Europe), and 915MHz (US).
To transmit RF signals, Wavenis employs Frequency Hopped Spread Spectrum (FHSS) techniques.
Here’s a summary of the key features of Wavenis technology:
| Specification | Wavenis Support |
|---|---|
| RF Frequency range | 868MHz (EU EN300-220), 915MHz (US FCC15-247,15-249), 433MHz |
| Data Rate | 4.8Kbps to 100 Kbps (Programmable) |
| Bandwidth | 50KHz |
| Modulation (PHY) | GFSK |
| Spread spectrum | FHSS |
| Coverage range | 1Km (Indoor) |
| Security | 128 bit AES |
| Wavenis PHY Data handling | Interleaving, Forward error Correction BCH(31,21) |
| Network Topology | Tree and star network topologies |
Wavenis commonly uses a data rate of 9.6Kbps in the 433/868MHz bands and 19.2Kbps in the 915MHz band.
Basic Applications of Wavenis
Wavenis systems are adaptable and can be used in a variety of network configurations. These range from simple point-to-point connections to more complex tree structures that incorporate multiple repeaters.
Products based on Wavenis technology can operate synchronously or asynchronously. There are also several Wavenis network architectures available, each suited to different applications.
Consider, for instance, a simple lighting control system or a point-to-point wireless remote reading system.
- A lighting control system might consist of switches and lights in a Point-to-Point or Point-to-Multipoint setup.
- An automatic remote monitoring application could include a gateway, repeaters, and endpoints.
Companies like Elster Water Metering Limited provide products and solutions that leverage Wavenis technology.
