Catchbox 2.4
2.4 GHz radio Spectrum Overview
The Catchbox 2.4 uses the 2.4 GHz ISM frequency band and is free to use without a license. While this
is very convenient, it also creates limitations and drawbacks, mainly caused by the prevalence of other
devices which also work in the same frequency band. To ensure flawless operation, the Catchbox 2.4
uses adaptive frequency hopping, antenna diversity, intelligent frequency management, and two way
audio packet control and buffering. This said, by understanding the limitations of 2.4 GHz systems and
knowing of ways to improve signal strength users can make sure that their device works as intended.
Limitations of 2.4 GHz Systems
Devices that operate in the 2.4 GHz frequency band have a limited range, usually around 20-30 m / 65-
100 ft in ideal working conditions. This, in turn, means the Catchbox 2.4 may not work in large events
where there is a long distance between the transmitter and the receiver. 2.4 GHz frequency signals
are also easily absorbed by walls, metallic materials, and human bodies. This means one should not
place the Catchbox 2.4 Receiver into another room from the transmitter, or place it inside a cupboard,
specifically a metal one. If there are many other devices that operate in the 2.4 GHz spectrum in the same
space (WiFi and Bluetooth enabled devices, such as smartphones and laptops) dropouts may occur due
to the frequency band being overcrowded. To avoid this, do not use the product in audiences with over
100 people, like large conferences or exhibitions.
Improving signal strength
Users can improve the performance of the system through the following measures:
• Ensure that there are no objects or walls between the receiver and transmitter.
• Keep the distance between the transmitter and the receiver short.
• Position the antennas of the receiver in a 45 degree pattern, like the letter V.
• Do not place the receiver or transmitter near other 2.4 GHz devices, such as laptops or WiFi routers.
• Avoid heavy wireless network activities, like downloading movies, in the same space.
This product may cause interference to other products and devices
operating in the 2.4 GHz ISM frequency band. These other devices
can also interfere with the wireless transmission of the device,
causing signal dropouts.
