6.1 Before Installation

6.1.1 What is the WD Wireless Network?

6.1.1.1 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 a wireless LAN. However, if the frequencies you use 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.

6.1.1.2 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 wireless channels in your instal-
lation environment.
・The relationship between frequency bands of channels on the WD wireless network and on the wireless LAN is
as follows.
・The frequency of each channel on the WD wireless network is as follows.
Mid-range frequency

CH12
CH13

CH15
CH16
CH17
CH18

6.1.1.3 Example Wireless Channel Selection

・When the wireless LAN uses three channels (CH1, CH6, and CH11), select either CH15, CH20, CH25, or CH26.
・In most cases, selecting CH25 or CH26 will enable you to avoid the wireless LAN channels.
