What is the WD Wireless Network?
①
About the WD Wireless Network
The WD wireless network operates on the IEEE802.15.4 (ZigBee) compliant 2.4 GHz frequency.
Although it runs on the same 2.4 GHz frequency as a wireless LAN (Wi-Fi), because it conforms to IEEE802.15.4 the WD
wireless network can operate without connecting to a wireless LAN. However, if the frequencies used overlap, the WD
wireless network could experience transmission delays and other communication issues.
The wireless communication is encrypted. The encryption standard used is AES-CCM (Advanced Encryption
Standard-Counter with CBC-MAC), with an encryption key of 128
bits.

About Selecting a Wireless Channel
The WD wireless network uses 16 wireless channels (CH11 to CH26).
Select a wireless channel to avoid conflict with the frequency band of the LAN's wireless channel in your installation
environment.
The relationship between frequency bands of channels on the WD wireless network and on the wireless LAN is as follows.
