The 802.11a standard uses the same core protocol as the original standard and was the first of the 802.11 family to operate in the 5 GHz band. It uses a 52-subcarrier orthogonal frequency-division multiplexing (OFDM) with a maximum raw data rate of 54 Mbit/s, which typically yields a throughput in the mid-20 Mbit/s.

OFDM takes an RF channel, such as the 20 MHz channel often used in Wi-Fi, and instead of using a single carrier-frequency modulated by AM, FM, or other means, sets out a number of sub-carriers. 802.11ac used 52 data-carrying sub-carriers in a 20 MHz RF channel, while 802.11ax has 234.
Read moreWhat is OFDM wireless?
Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency .

OFDM-based wireless LANs will be implemented in the 2.4GHz ISM band as well as the 5GHz band. OFDM WLANs provide very high data rates, resilience to multipath and extended operating range.
Read moreHow is MCS determined?
MCS depends on radio link quality . The better quality the higher MCS and the more useful data can be transmitted. And vice versa the worse radio conditions the lower MCS and the less useful data can be transmitted. In other words MCS depends on error probability.
Read moreWhat is the MCS used for?
The purpose of an MCS in a plasmid is to allow a piece of DNA to be inserted into that region . An MCS is found in a variety of vectors, including cloning vectors to increase the number of copies of target DNA, and in expression vectors to create a protein product.
Read moreWhat is MCS in 5G?
For any communication technology, Modulation and Coding Scheme (MCS) defines the numbers of useful bits which can carried by one symbol . In contrast with 5G or 4G, a symbol is defined as Resource Element (RE) and MCS defined as how many useful bits can be transmitted per Resource Element (RE) .
