How to detect whether device has 5Ghz Wi-Fi or not

Question

I spent much time by seaching for solution but without result. So my question is, is there any way how to detect whether device has 5Ghz Wifi or not? It would be nice if it's possible to achieve that. I already analysed WifiManager but didn't find proper method or property.

Thanks in advance.

As of Android API Level 21, WifiManager has a method called is5GHzBandSupported() that returns true if the adapter supports 5 GHz band.

Our approach is to look for the results of a wifi scan and look for a signal of 5GHz. That's not a good solution, 'cause it would give false negatives, but if your context is a venue where you can assure that there are 5GHz wifis near you, it can solve the issue.

See: How can I get Android Wifi Scan Results into a list?

Hope it helps!

Probably it's a A/C router, with two signals...? – Roc Boronat Apr 02 '15 at 09:48
Does it mean this approach will only work if there are 5GHz networks around? – surlac Feb 12 '16 at 01:56

Yes. That's exactly what the answer says :·) – Roc Boronat Feb 13 '16 at 12:51

I resolved this using below code snip

        WifiManager wifiManager= (WifiManager) mContext.getApplicationContext().getSystemService(WIFI_SERVICE);
        Class cls = Class.forName("android.net.wifi.WifiManager");
        Method method = cls.getMethod("isDualBandSupported");

        Object invoke = method.invoke(wifiManager);
        boolean is5GhzSupported=(boolean)invoke;
