Many of these channels can support widths between 20 – 80 MHz. The 5 GHz band has over 100 channels, with 24 that don’t overlap. Its device compatibility is relatively new compared to 2.4 GHz but is still readily available for most Wi-Fi options. However, because 5 GHz waves are smaller, faster, and less congested, this Wi-Fi frequency is useful in many specialized devices, such as medical equipment.ĥ GHz became part of the Wi-Fi standard in 2009. SHF is highly dependent on line of sight, and it rarely penetrates walls as reliably as UHF. The SHF wavelength is so small it qualifies as a microwave (a tiny wave, not a cooking device). SHF is a higher frequency range than UHF. It falls within the super high frequency (SHF) of radio signals. What is 5 GHz Wi-Fi?ĥ GHz is the current commuter highway of Wi-Fi frequency, where traffic can travel faster through less congestion, but only at a shorter distance. A 2.4 GHz network may not be able to support high-bandwidth needs. However, this Wi-Fi frequency struggles with slower speeds, interference, and congestion. These channels are also relatively narrow at around 5 MHz wide, making the frequency more susceptible to interference.Īs with most highly-used public access highways, the 2.4 GHz band can also get congested with traffic, especially during peak usage (rush hour) times.Ģ.4 GHz is good for in-home networks because its longer range and stronger signal penetration can reliably connect to devices in other rooms. The 2.4 GHz radio band has eleven channels, with only three channels that don’t overlap.

Cell phones, routers, baby monitors, smart TVs, and Bluetooth accessories use this Wi-Fi frequency.

This makes 2.4 GHz a practical choice for many professional and personal devices.Ģ.4 GHz has been used since the first Wi-Fi standard in 1997, so almost all wireless devices are default compatible. It can penetrate through most standard walls. UHF can travel for miles over the visual horizon unless blocked by terrain or buildings. UHF is a mid-range frequency, balanced between larger wavelengths affected by upper atmospheric interference, and smaller wavelengths with an easily obstructed short range. It falls within the ultra-high-frequency range (UHF) of radio signals. Wider lanes and fewer overlaps result in higher bandwidth performance.Ģ.4 GHz is the standard public highway for Wi-Fi. Like merging lanes, channel overlap may cause traffic to collide (interference). The frequency channel will also affect bandwidth performance. The higher the frequency, the higher the potential bandwidth. Bandwidth is the data transfer rate, measured as bits per second (Mbps). Higher bandwidth can transfer more data. The amount of traffic the system can convey within a specific time period is bandwidth. Like a lane, a channel's width and overlap can affect the band’s flow of traffic. A shorter frequency (2.4 GHz) is slower but travels farther.īoth bands have their own designated Wi-Fi channels or highway lanes. Like how a car uses gasoline, a higher frequency (5 GHz) has a faster speed but covers less distance. The wireless frequency refers to the car’s speed and distance it travels through the highway. If you think of radio bands as a highway system and the signal waves as cars, 2.4 and 5 GHz are the designated highways for these cars to travel between various locations (Wi-Fi devices). There are currently two Wi-Fi options, the 2.4 and 5 GHz radio band frequencies. Here, GHz refers to the frequency between the devices that send and receive the Wi-Fi signal waves. The more cycles per second, the higher the frequency. In practical terms, this means a gigahertz sends around one billion cycles per second. The Hz unit measures frequencies with waves, such as radio waves, sound waves, and electric currents.Ī hertz is one cycle per second, a megahertz (MHz) is 1,000,000 hertz per second, and a gigahertz is 1,000 MHz (1,000,000,000 Hz) per second. Hertz (Hz) is simply the technical term for the number of cycles per second or frequency.
