There is no perfect frequency band for a wireless mic system. Every frequency band has pros and cons. GLX-D operates within the 2.4GHz ISM band which is utilized by Wi-Fi, Bluetooth, and other wireless devices.
2.4 GHz Pros
2.4 GHz Cons
NOTE: In theory, it is feasible to simultaneously operate up to eight GLX-D systems in one venue under optimal conditions. However, local interference in the 2.4 GHz band will often reduce this number to four or less. GLX-D Advanced receivers with the UA846Z2 Frequency manager greatly help improve the performance of larger systems.
The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable. GLX-D meets these challenges as follows:
Coexisting with Wi-Fi
The best way to co-exist with WiFi is to force the WiFi system to run in the 5 GHz band, leaving the 2.4 GHz band available for GLX-D. Consult your Wi-Fi router’s manual to set this up.
If this is not possible, and Wi-Fi will be active during a performance, turn on Wi-Fi devices prior to turning on GLX-D and scanning for the best channel. Be sure the WiFi is not configured for Automatic Channel mode–set it to a specific channel. GLX-D when then detect and avoid other Wi-Fi traffic by scanning the entire 2.4GHz environment and selecting the three best frequencies to transmit on. “Bursting” or frequency-changing Wi-Fi is harder to detect as it is periodic; however, because GLX-D repeats the most important information, even bursts at very high-levels often will not have an effect on audio performance. If there is a Wi-Fi transmitting device in use, the GLX-D receiver must be placed at least 10 feet away from the device.
Challenging Wireless Environments
Some environments are more difficult than others for 2.4 GHz wireless system performance. Additionally, RF signal absorption by the human body has a greater impact in the 2.4 GHz spectrum, compared to the UHF spectrum. The simplest solution often is to reduce the transmitter to receiver distance such as placing the receiver on the stage with a clear line of sight. Challenging environments include:
Predicted Operating Distance
However, adverse local RF conditions can limit GLX-D operating distance to as little as 10 to 20 feet. In the worst case, the GLX-D may not operate at all. Please read this: Conversation at a Loud Party and Wireless Microphones
