A wireless network has become almost mandatory for every small business. A wireless network is relatively easy for non-technical people to install, and it’s convenient for users, who can use it to connect to the network and the Internet from anywhere in the building. But Wi-Fi does present a challenge that’s unique to the radio signals it uses to transmit data: interference. In this Mythbusters post, we’ll clear up the misconception that there’s no interference on the 5GHz channel.
A Wi-Fi network can use one of two frequency bands to send and receive radio waves: 2.4 GHz and 5 GHz. These frequencies are much higher than those used for other radios, like cell phones and walkie-talkies, so the Wi-Fi signal can carry considerably more data. All Wi-Fi networks use the wireless 802.11 networking standard; the difference is in which band you set your wireless router or access point to transmit on. 802.11b and 802.11g operate at the 2.4 GHz band, while 802.11a transmits at 5 GHz. Unlike the other variations of the standard, 802.11n can operate at both bands.
