Figure 6.9 IEEE 802.11 authentication, re-authentication, and handover delay with IEEE 802.11i
with EAP-TLS and IEEE 802.11f. Note: In Japan there are 4 non overlapping
channels; therefore the STA will send probe request in 3 channels for handover; in
other countries there are 3 non overlapping channels; thus the STA will send probe
request in other 2 channels.
