Wireless Link Mode and Communications 

The table below shows which wireless terminals can communicate with each other depending on the 

operating mode of the AP and user unit. 

[Table notation and notes] 

1.  UU stands for “user unit”. 

2. AP

⇔

UU indicates communications between a unit type AP and user unit. 

3.  ST indicates an “AP managed by (logged in to) another AP” which operates in the same way as a 

user unit.  See Chapter 5 for details of the setup procedure.
