About Wireless Interference


This page explains the radio wave used by DS-520AN.


DS-520AN operates at 2.4GHz and 5GHz bands.
No radio license is required to use DS-520AN, however, please give attention of the followings:


Do not use DS-520AN near the following devices or places.

The following devices may use the same band. If you use DS-520AN near these devices, the radio waves emitted from DS-520AN and the following devices may interfere with each other.


Do not use DS-520AN near a cellular phone, TV or Radio.

A cellular phone, TV and radio use a different radio band than our products. Generally, if they are used near DS-520AN, it will not cause any problems. However, when they approximate DS-520AN, sound or image noise may occur.


If there is reinforced concrete/metal between wireless devices, they may not connect.

DS-520AN can connect through wood or glass, but may have troubles connecting through reinforced concrete/metal.


Wireless devices using 2.4GHz band

The same frequency band of DS-520AN is used for a microwave, industry, science, medical equipment and licensed in room or low power (non licensed) radio stations.


2.4 : Shows the frequency of the device is 2.4GHz.
DS/OF : Shows the used modulation is DS-SS and OFDM.
4 : Shows the range of interference is (<=40m).
: Shows that different channels can be used to avoid interference.

Notes on using 5GHz band
