NOTE:
In each of these following designs, Link 2 is not on the same frequency band as
Link 4. (For example, Link 2 may be a 5.2-GHz link while Link 4 is a 5.7- or 2.4-
GHz link.)
• Design 3
o A CMM provides sync to a co-located AP.
o This AP sends the sync over the air to an SM.
o This SM delivers the sync to a co-located AP.
o This AP passes the sync in the additional link over the air to SMs.
This design is illustrated in Figure 29.

• Design 4
o A CMM provides sync to a co-located AP.
o This AP sends the sync over the air to an SM.
o This SM delivers the sync to a co-located BHM.
o This BHM passes the sync in the additional link over the air to a BHS.
This design is illustrated in Figure 30.
