2.4 GHz or 5 GHz?

Reaches the shed through two walls, has only three clear channels, gives the fastest rate in an open office: which band?

About this interactive

The lesson's comparison: - **2.4 GHz:** larger coverage area and better through obstructions such as walls, but a very crowded space, shared with many devices, microwave ovens among them. Each channel needs a range of frequencies around it, and those ranges overlap, so only channels 1, 6 and 11 can sit side by side without interfering. - **5 GHz:** a higher data rate, many more channels, and less interference, since fewer things use it. It does not travel as far and is stopped more by walls. Lower frequencies travel farther, like the bass you hear first from a passing car.

Key terms

Frequency Band
A designated range of radio frequencies allocated for a specific use, such as the 2.4 GHz or 5 GHz bands used by Wi-Fi.
Channel
A specific range of frequencies within a Wi-Fi frequency band used to transmit and receive wireless data.
Non-Overlapping Channels
Channels within the 2.4 GHz band that do not share frequency ranges with each other; in the 2.4 GHz band these are channels 1, 6, and 11.
Co-Channel Interference
Interference that occurs when two or more wireless access points transmit on the same or overlapping channels within range of each other.
Unlicensed Band
A range of electromagnetic frequencies, such as 2.4 GHz, that can be used for wireless communication without requiring a government-issued license.
