Mimo - Study guides, Class notes & Summaries

NCTI WIFI (2022/2023) Rated A+ Notes Single input, single output (SISO) - Most systems have one radio and one antenna, and some systems have one radio and two antennas. Multiple input, multiple output (MIMO) - These systems use multiple radio chains in a single wireless chipset. Multi-user MIMO (MU-MIMO) - These systems use each radio chain on an access point to transmit to a unique client.Correct answer: Wired Equivalent Protection (WEP) - This type of security setup should never be use...
