" _dwb " suffix compulsory for wifi back haul SSID ?

[kishork]

i read somewhere that it's a RULE that wifi back haul SSID must be same as SmartConnect SSID followed by _dwb

for example as per this if the SSID is abcd then back haul SSID must be abcd_dwb ?

is this true ? we should not have any other SSID name for back haul ?
