802.11n

The 802.11n WiFi standard was adopted in 2008 and was considered a significant upgrade from the previous 802.11g802.11g: The 802.11g WiFi Standard, developed by the Institute of Electrical and Electronics Engineers (IEEE), offers wireless network transmission over short distances at up to 54 Mbps data rate. Operating in the 2.4 GHz band, it is backward compatible with 802.11b, allowing seamless integration with… standard. This standard provides a higher throughput and improved range, making it a more reliable and efficient wireless connection. Operating on both 2.4 GHz and 5 GHz frequency bands, it offers a theoretical maximum speed of up to 600 Mbps. This is achieved by utilising multiple-input multiple-output (MIMO) technology, which uses several antennas to send and receive up to four spatial streams, resulting in enhanced performance. The 802.11n standard also includes other features such as frame aggregation and channel bonding. Frame aggregation increases the throughput by sending two or more data frames in a single transmission, while channel bonding combines two 20 MHz channels into a single 40 MHz channel, doubling the channel width to increase throughput. The 802.11n standard is backward compatible with 802.11a802.11a: 802.11a, part of the "WiFi-2" standard adopted in 1999 operates in the 5 GHz frequency band and can deliver data rates up to 54 Mbps. It uses orthogonal frequency-division multiplexing (OFDM) which is more efficient and less susceptible to interference. The higher frequency has a shorter range than…, 802.11b802.11b: The 802.11b WiFi Standard, also known as "WiFi 1", was adopted in September 1999 and operated on a 2.4 GHz frequency band. The standard offers a maximum theoretical bandwidth of 11 Mbps, although in practice, the actual data transfer speed is typically less than 6 Mbps. The 802.11b standard…, and 802.11g, meaning devices supporting these older standards can connect to an 802.11n network. However, the speed will be limited to the maximum speed of the older standard.
