AIR-ANT2566P4W-R

An antenna gives the wireless system three fundamental properties: gain, direction, and polarization. Gainis a measure of increase in power. Directionis the shape of the transmission pattern. A good analogy for an antenna is the reflector in a flashlight. The reflector concentrates and intensifies the light beam in a particular direction similar to what a parabolic dish antenna would do to an RF source in a radio system.

Antenna gain is measured in decibels, which is a ratio between two values. The gain of a specific antenna is compared to the gain of an isotropic antenna. An isotropic antenna is a theoretical antenna with a uniform three-dimensional radiation pattern (similar to a light bulb with no reflector). The decibels over an isotropic radiator (dBi) value is used to compare the power level of a given antenna to the theoretical isotropic antenna. The U.S. regulatory agency (the Federal Communications Commission, or FCC) uses dBi in its calculations. An isotropic antenna is said to have a power rating of 0 dB, meaning that it has zero gain/loss when compared to itself.

Unlike isotropic antennas, dipole antennas are real antennas. Dipole antennas have a different radiation pattern compared to isotropic antennas. The dipole radiation pattern is 360 degrees in the horizontal plane and 75 degrees in the vertical plane (assuming the dipole antenna is standing vertically) and resembles a doughnut in shape. Because the beam is “slightly” concentrated, dipole antennas have a gain over isotropic antennas of 2.14 dB in the horizontal plane. Dipole antennas are said to have a gain of 2.14 dBi (in comparison to an isotropic antenna).

Some antennas are rated in comparison to dipole antennas. This is denoted by the suffix dBd, short for decibels over a dipole antenna. Hence, dipole antennas have a gain of 0 dBd (= 2.14 dBi).

Note that the majority of documentation refers to dipole antennas as having a gain of 2.2 dBi. The actual figure is 2.14 dBi, but it is often rounded up.

What is WiFi 6? (802.11ax)

Wi-Fi 6, also known as 802.11ax, is changing the way we connect to and consume information. The Wi-Fi 6 standard builds on the strengths of earlier Wi-Fi standards while improving efficiency, flexibility, and scalability.

What are the benefits of Wi-Fi 6?

With Wi-Fi 6, organizations and service providers can support new and emerging applications on the same wireless LAN (WLAN) infrastructure while delivering a higher grade of service to older applications. This scenario sets the stage for new business models and increased Wi-Fi adoption.

Is Wi-Fi 6 different from 802.11ax?

No, the terms are synonymous. The Wi-Fi Alliance campaigned to coin the term “Wi-Fi 6” to refer to the IEEE 802.11ax standard. The term indicates that it is the sixth generation of Wi-Fi. The premise was to simplify the marketing message to help 802.11ax be better positioned relative to the Third Generation Partnership Project (3GPP) standards used in cellular (such as 5G).

When was Wi-Fi 6 ratified?

 The Wi-Fi Alliance fully ratified Wi-Fi 6 in 2020. Most recently, the Wi-Fi Alliance added Wi-Fi Certified 6E.
