Continuing the series of articles on the protocols in IoT applications that design engineers need to know, today plc247.com and your friends learn about physical communication protocols: Z-Wave
Like Zigbee, Z-Wave is a wireless communication standard over short distances and uses very little power. The transmission capacity at 100kbit / s is more than enough for the need to communicate between devices in IoT and M2M systems. Z-Wave and Zigbee connectivity standards operate at 2.4GHz, and are designed with very low power consumption, so they can be used with mobile batterys. Zwave operates at lower frequencies. Compared to Zigbee / Wifi, it fluctuates in the frequency bands of 900Mhz, depending on the regulations in each different region.
The advantages of Z-Wave are extremely low power consumption and extremely high open platform. Currently, Z-Wave is mainly used in smarthome applications. In particular, every Z-Wave device in the system is a device that can both receive and broadcast, thus improving system stability.
In particular, Z-Wave has been integrated into many device manufacturers, this is a technology that is getting attention and manufacturers are focusing more on it.
Basic specifications of Z-Wave:
+ Standard: Z-Wave Alliance ZAD12837 / ITU-T G.9959
+ Frequency: 900MHz (ISM)
+ Range: 30m
+ Data Rates: 9.6/40/100kbit/s
