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 used for a wireless network as it ...
