The Wi-Fi Alliance has introduced the term "Wi-Fi 6E" to identify and certify IEEE 802.11ax devices that support this new band, which is also used by Wi-Fi 7 (IEEE 802.11be). Korea Frequency Distribution Table (Ministry of Science and ICT Commission No. 2019-87, 2019.10.18)] (in Korean) . Retrieved 2017-08-02. of spectrum from 4940 to 4990MHz (WLAN channels 20–26) are in use by public safety entities in the United States. Within this spectrum there are two non-overlapping channels allocated, each 20MHz wide. The most commonly used channels are 22 and 26.

Non-Americans often refer to the standard form in math in connection with a very different topic. To be precise, they understand it as the basic way of writing numbers (with decimals) using the decimal base (as opposed to, say, the binary base), which we can decompose into terms representing the consecutive digits.

Countries apply their own regulations to allowable channels, allowed users and maximum power levels within these frequency ranges. The ISM band ranges are also often used

Rules for expressions with fractions: Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts. Technical Specifications for Low Power Radio Frequency Equipment] (PDF) (in Chinese).

B In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions. The 2.4GHz Part 15 band in the US allows spread-spectrum operation as long as the 50dB bandwidth of the signal is within the range of 2,400–2,483.5MHz [11] which fully encompasses channels 1 through 13. We begin our investigation of continuity by exploring what it means for a function to have continuity at a point. Intuitively, a function is continuous at a particular point if there is no break in its graph at that point. Continuity at a Point
