5 GHz band

(redirected from 5GHz band)

5 GHz band

The frequency range from 5.15 GHz to 5.85 GHz, which is unlicensed and used for many communications applications, including Wi-Fi and cordless phones. Commonly designated as "5G," after the turn of the century, 5G became widespread after version 802.11a debuted. The 5 GHz band is also used in the subsequent 11n, 11ac and 11ax versions of Wi-Fi. See 5G, 802.11 versions and ISM band.

2.4 GHz and 5 GHz
One often sees 2.4 GHz and 5 GHz (2.4G and 5G) written together because they refer to the two common Wi-Fi frequency bands. The reason 5 GHz is expressed as a whole number but 2.4 GHz has the dot-4 is because the 5 GHz band covers a range from 5.15 GHz to 5.85 GHz, and it is shortened for simplicity to 5 GHz. However, the 2.4 GHz range is entirely within 2.4 GHz (see 2.4 GHz band).

To eliminate Wi-Fi interference for faster and more reliable Internet, the AC1900 Wi-Fi Router also features dual-band technology, enabling users to perform simple Internet activities on the 2.4GHz band, and more demanding activities on the cleaner, interference-free 5GHz band. The router also features a brand new user tested interface built for mobile devices that offers the simplest router interface available on the market.
While the 2.4GHz band can be extremely crowded with congestion and signal interference from WiFi networks at home, workplaces and public places, the 5GHz band is a much cleaner band with eight times more channels, resulting in much higher throughput speeds.
The new standard which operates at the 5GHz band exclusively, aims to improve Wi- Fi capabilities by increasing modem speed and enabling operation at 80MHz bonded Wi-Fi channels.
