The so-called wireless LAN (Wi-Fi) standard provides an identifier called "Service Set Identifier (SSID)" at the access point.If there are multiple access points in the same network, the user can rely on this SSID and is actually used as the name of the router/Wi-Fi access point.
Therefore, if a router/Wi-Fi access point is newly established, the SSID is also set, but in that case, the SSID may not be released (broadcast), sometimes "stealth mode".Even if SSID is changed to stealth mode, the function as an access point does not change, but the SSID is not displayed on the SSID list screen of the Wi-Fi slave unit (in iOS, "setting" → "Wi-Fi").increase.You can not connect unless you input SSID, so use the access point if you do not want others to be known.
However, if the Wi-Fi access point is set to stealth mode, the power consumption of the iPhone may increase.In normal (non-stealth mode), the Wi-Fi access point informs the surroundings by regularly transmitting the signal, but in the stealth mode, the Wi-Fi slave unit searches for access points.You have to communicate regularly, and you consume power.
Apple has a description in the document "iOS introduction reference" that "avoid the use of" private "SSID" (link).Even if there are no security benefits, it seems that it is not necessary to dare to make the Wi-Fi access point at home into stealth mode.
