Broadly speaking, there are three types of WiFi antennas: Directional antennas, Omnidirectional antennas, and Sector antennas. The primary distinction lies in the signal beamwidth. Learn more about each in their respective subcategories. All three types of WiFi antennas are available in our shop.
Essentially, there are two main frequency bands for operating a license-free WLAN network: the 2.4 GHz and the 5 GHz frequency bands:
The 2.4 GHz frequency band, adhering to standards IEEE 802.11b/g/n, is somewhat less susceptible than the 5 GHz band but has a very limited number of channels. In comparison, this frequency range allows for lower bandwidths and quickly becomes congested with too many WiFi networks. But it also has its advatages. The wavelenght is higher and more robust than 5 GHz.
The 5 GHz frequency band, following standards IEEE 802.11 a/n/ac/ax, is relatively more susceptible to interference than the 2.4 GHz band. However, it offers a significantly greater number of channels and is, therefore, increasingly preferred. The broad frequency spectrum here allows for extremely high data rates. Recently, the 802.11ax (WiFi 6) standard expanded, and with the WiFi 6E standard, new frequency ranges have been introduced, resulting in even higher data rates.
