FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -MIMO is unquestionably the biggest development for 802.11n and the key to the new speeds. Essentially, MIMO uses multiplexing to increase the range and speed of wireless networking. Multiplexing is a technique that combines multiple signals for transmission over a single line or medium.

Detailed explanation-2: -802.11n, an addition to the 802.11 family of standards, will increase wireless local area network(WLAN) speed, improve reliability and extend the range of wireless transmissions. 802.11n uses multiple input / multiple output (MIMO) technology and a wider radio frequency channel.

Detailed explanation-3: -802.11n (Wi-Fi 4) 802.11n used MIMO (Multiple Input Multiple Output) where multiple transmitters/receivers could operate simultaneously at one or both ends of the link to a single device. This provided a significant increase in data without needing a higher bandwidth or transmit power.

Detailed explanation-4: -The 802.11n standard uses some new technology and tweaks existing technologies to give Wi-Fi more speed and range. The most notable new technology is called multiple input, multiple output (MIMO). MIMO uses several antennas to move multiple data streams from one place to another.

Detailed explanation-5: -The first wave of 802.11n that hit in 2007 was composed of products that supported sustained 100 Mbps throughput, and, with the configuration of protocol options for maximum speed, up to a 300 Mbps link rate. The second wave hit in 2011, with products that featured data rates up to 450 Mbps.
