Detailed explanation-1: -BLE works in the 2.4 GHz frequency band, which is known as the Industrial, Scientific and Medical (ISM) band. In this ISM band, there are diverse wireless communication protocols coexisting such as Bluetooth, Wi-Fi, ZigBee, etc.
Detailed explanation-2: -A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, security cameras, and garage door openers. If you have many of these in your home, or if you live in an apartment or condo, that 2.4 GHz band is likely to be congested, which can damage speed and signal quality.
Detailed explanation-3: -Bluetooth Low Energy uses the same 2.4 GHz radio frequencies as classic Bluetooth, which allows dual-mode devices to share a single radio antenna, but uses a simpler modulation system.
