Is it possible to display Wi-Fi channel availability or 3G signal strength together with additional details?
Because of security/privacy reasons (wifi network names or cell towers could be used to locate your device by app developers, wifi security type could be used to find networks with weak encryption, etc.), iOS provides very little information about the connected/available wifi or cell networks. For this reason, the following features (available e.g. in the in the Android version of the app) cannot be implemented under iOS by 3rd party developers:
- wifi signal strength/coverage (RSSI) meter
- channel number availability finder
- SSID or hidden SSID finder
- wifi security type (WEP, WPA, WPA2, AES, TKIP)
- transmit rate
- PHY mode (b/g/n/ac)
- MCS index
- frequency (2.4GHz, 5GHz)
- cell tower list
- cell tower signal strength data
If ever Apple makes this information available to developers (which I find very unlikely), I'll immediately add support for it in my apps.
Note: It is possible to use Apple's own Airport Utility app (which, being developed by Apple, doesn't have to follow the restrictions 3rd party apps have to) to show surrounding wifi networks, their signal strengths and channels used.
