Why is ZigBee more expensive than WiFi?
Zigbee devices are typically more expensive because they have to comply with various specifications from the Zigbee Alliance – giving rise to various subtle benefits compared to non-Zigbee devices.
Does ZigBee use CDMA?
For short distance (among sensors in the bridge) ZigBee wireless network is tested, and CDMA for long distance (between the bridge and the management center) data communication is tested.
Is ZigBee Wi-Fi or Bluetooth?
