The 2.4 GHz band is commonly used for various wireless communication applications, including Wi-Fi, Bluetooth, and some wireless microphone systems. However, there are several disadvantages associated with using the 2.4 GHz band for wireless microphones:

• Interference from other devices:The 2.4 GHz band is congested with a variety of devices, including Wi-Fi routers, Bluetooth gadgets, and even microwave ovens, which can lead to potential signal conflicts and degradation.
• Limited available channels: High congestion in the band restricts the number of clear frequencies available for wireless microphones, making it challenging to find reliable operating frequencies.
• Shorter operational range: Compared to lower frequency bands like UHF, the 2.4 GHz band typically offers a shorter range, which can be limiting in larger venues or outdoor settings.
• Potential for signal dropout: Interference and congestion can cause frequent signal dropouts, impacting the reliability of wireless microphone systems, especially during critical live performances.
• Vulnerability to environmental factors: Signals in the 2.4 GHz band are susceptible to interference from physical obstacles like walls, furniture, and other obstructions, further compromising signal quality and reliability.
