Tips and Methods to Improve Wireless System Performance

1) Keep more than 3 meteres distance between Receiver 

unit and other WiFi transmitters such as routers.

2) Change channels to avoid interference with other WiFi

products.

3) In case of environmental interference from other WiFi

systems, shorten the distance between the receiver
and transmitter units.

2.4Ghz Frequency Tables

U4 operates within the 2.4GHz ISM band which is utilized 
by Wi-Fi, Bluetooth, and other wireless devices. 2.4GHz is 
an open band and, as such, does not require a license to 
be used worldwide.

* U2 1~4 channels are the same as U3/U3C/U4 1~4 channels, 

U2, U3/U3C and U4 use in sametime max is 6 sets.
