Detailed explanation-1: -Gigahertz, or GHz, is equivalent to 1 billion hertz, and is a common unit of measurement of computer processing speed, alternating current, and electromagnetic (EM) frequencies. When it comes to WiFi, the difference between 2.4 and 5 GHz indicates the connectivity speed a router can support.
Detailed explanation-2: -For example your car stereo receives frequencies in Kilohertz and Megahertz range (AM and FM stations), and WiFi transmits and receives data in the Gigahertz range. To break it down even further, Hertz (Hz) is simply a unit of frequency.
Detailed explanation-3: -The 2.4 GHz band provides the most coverage but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds. The 6 GHz band, introduced with the new WiFi 6E standard, provides the least coverage but transmits data at the fastest speeds of the three frequencies.
Detailed explanation-4: -All Wi-Fi routers have a 2.4Ghz band, but the newer routers are often dual-band router with 2.4Ghz and 5Ghz bands. If both of your 2.4Ghz and 5Ghz have the same name (SSID) and password, then you won’t have any problem connecting to your Briiv regardless which Wi-Fi band your smartphone is connected to.
