First, let’s briefly talk about the Wi-Fi routers that offer these bands, and then we’ll explore what makes them different in-depth. In some cases, the difference is negligible in others, it makes all the difference. You’ve probably seen Wi-Fi networks split into two selections before: 2.4 GHz and 5 GHz - but what’s the difference? The 5 GHz band covers a shorter distance, but also provides the fastest speeds. Other, less common sources of RF interference include video cameras, baby monitors, power lines, electrical railroad tracks, and direct satellite providers.The bottom line: The 2.4 GHz band has a longer transmission range, but offers slower speeds. Bluetooth devices use the 2.4 GHz band, hopping over 802.11 transmissions and sometimes bumping into them (especially when it comes to older 2.4ghz 802.11b networks). Today, Bluetooth connectivity is present in everything from headphones and speakers to watches and health monitors to smartphones and tablets, and much more. Bluetooth devices: Unlike cordless phones, the number of Bluetooth devices in use has been increasing at a very high rate, driven by the growing popularity of the Internet of Things and smart home devices.The good news is that cordless phones are gradually becoming obsolete, replaced by cellphones and VoIP phones, so their impact on WiFi networks is usually not drastic.

Cordless phones: Most cordless phones use the 900 MHz, 2.4 GHz, and 5 GHz bands, with 2.4-GHz cordless phones being the most common.

The most important thing is to never place a microwave oven close to a WiFi router. Because microwave ovens emit interfering signals only when they are in use, measuring their impact can be problematic even with a capable interference detector.

Microwave ovens: Not all microwave ovens are WiFi killers, but some models are capable of emitting interfering signals that occupy the entire 2.4 GHz band at up to 25 feet.

Both types of WiFi interference are bad and should be avoided with the help of an RF interference scanner capable of revealing WiFi channel usage. When two or more WiFi networks transmit on adjacent channels, the so-called adjacent-channel interference occurs. When two or more WiFi networks transmit on the same channel, the so-called co-channel interference occurs.

Other WiFi networks: Most WiFi networks today use the 2.4 GHz band, which is divided into several channels, only three of which are non-overlapping.
