Question 6

A customer requires APs that meet these minimal criteria: Support for MU-MIMO Support for up to four spatial streams, both when MU-MIMO is used and when it is not used Support for transmissions to up to three MU-MIMO clients at the same time The architect finds these specifications for the two models under consideration: AP-335 = 4x4:4:4:3 AP-325 = 4x4:4:3:3 What should the architect determine from these specifications?

Accepted Answer

The AP 335 and the AP 325 both meet the customer requirements. The customer requires support for MU-MIMO, up to four spatial streams, and transmissions to up to three MU-MIMO clients at the same time. The AP 335 has a specification of 4x4:4:4:3, which means it supports four spatial streams, four spatial streams when MU-MIMO is used, four spatial streams when MU-MIMO is not used, and three MU-MIMO clients. The AP 325 has a specification of 4x4:4:3:3, which means it supports four spatial streams, four spatial streams when MU-MIMO is used, three spatial streams when MU-MIMO is not used, and three MU-MIMO clients. Therefore, both the AP 335 and the AP 325 meet the customer requirements.
