Detect carrier connection type (3G / EDGE / GPRS)

Question

How can i get the type of connection of a carrier network?

• I'm able to get if connection is WIFI or WWAN using Reachability class

• I'm able to get network flags

  Reachability Flag Status: WR t------ localWiFiStatusForFlags

• I'm able to get WIFI SSID using CaptiveNetwork

Supported interfaces: ( en0 )

en0 => {       BSSID = "xx:xx:xx:xx:xx:xx";       SSID = MyWifiNetwork;       SSIDDATA = <x1x1x1x1 x1x1x1x1 x1>;   }   

But i'm not able to differenziate 3G, EDGE or GPRS connection.

Any idea also using iOS private API?

thanks.

From iOS 7 on you can use:

CTTelephonyNetworkInfo *telephonyInfo = [CTTelephonyNetworkInfo new]; NSLog(@"Current Radio Access Technology: %@", telephonyInfo.currentRadioAccessTechnology); [NSNotificationCenter.defaultCenter addObserverForName:CTRadioAccessTechnologyDidChangeNotification                                                  object:nil                                                   queue:nil                                              usingBlock:^(NSNotification *note)  {     NSLog(@"New Radio Access Technology: %@", telephonyInfo.currentRadioAccessTechnology); }]; 

I have also found this to detect a slow or fast connection:

- (BOOL)isFast:(NSString*)radioAccessTechnology {     if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyGPRS]) {         return NO;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyEdge]) {         return NO;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyWCDMA]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyHSDPA]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyHSUPA]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMA1x]) {         return NO;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORev0]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORevA]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORevB]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyeHRPD]) {         return YES;     } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyLTE]) {         return YES;     }      return YES; }

Here the OLD solution, using private API, in particular SoftwareUpdateServices.framework

Class NetworkMonitor = NSClassFromString(@"SUNetworkMonitor"); NSLog(@"TYPE: %d", [NetworkMonitor currentNetworkType]); 

It returns:

0: NO DATA
1: WIFI
2: GPRS/EDGE
3: 3G

hope this helps community.
