Ghz Radio Spectrum Overview - Catchbox Lite User Manual

2.4 GHz radio Spectrum Overview

The Catchbox Lite uses the 2.4 GHz ISM frequency band as 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 Lite
uses adaptive frequency hopping, antenna diversity, intelligent frequenct management, and two way
audio packet control and bu ering. This said, by understanding the limitations of 2.4 GHz systems and
knowing of ways to improve signal strenght 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 20-30m / 65-
100 ft in ideal working conditions. This, in turn, means the Catchbox Lite 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 Lite Receiver into another room from the transmitter, or place it inside a cupboard, spe
cifically 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 strenght
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 frequency band. These other devices can also interfere with the
wireless transmission of the device, causing signal dropouts.
