I have an indicator on my application to display the network type (2G or 3G or 4G) but after getting the network type, how do I know what speed category it should be in?

I know how to detect the network type:

    private TelephonyManager telephonyManager;
    telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    CurrentNetworkType = telephonyManager.getNetworkType();

Given the possible return values:

    //   public static final int NETWORK_TYPE_1xRTT
    //   Since: API Level 4
    //   Current network is 1xRTT
    //   Constant Value: 7 (0x00000007)
    //   
    //   public static final int NETWORK_TYPE_CDMA
    //   Since: API Level 4
    //   Current network is CDMA: Either IS95A or IS95B
    //   Constant Value: 4 (0x00000004)
    //   
    //   public static final int NETWORK_TYPE_EDGE
    //   Since: API Level 1
    //   Current network is EDGE
    //   Constant Value: 2 (0x00000002)
    //   
    //   public static final int NETWORK_TYPE_EHRPD
    //   Since: API Level 11
    //   Current network is eHRPD
    //   Constant Value: 14 (0x0000000e)
    //   
    //   public static final int NETWORK_TYPE_EVDO_0
    //   Since: API Level 4
    //   Current network is EVDO revision 0
    //   Constant Value: 5 (0x00000005)
    //   
    //   public static final int NETWORK_TYPE_EVDO_A
    //   Since: API Level 4
    //   Current network is EVDO revision A
    //   Constant Value: 6 (0x00000006)
    //   
    //   public static final int NETWORK_TYPE_EVDO_B
    //   Since: API Level 9
    //   Current network is EVDO revision B
    //   Constant Value: 12 (0x0000000c)
    //   
    //   public static final int NETWORK_TYPE_GPRS
    //   Since: API Level 1
    //   Current network is GPRS
    //   Constant Value: 1 (0x00000001)
    //   
    //   public static final int NETWORK_TYPE_HSDPA
    //   Since: API Level 5
    //   Current network is HSDPA
    //   Constant Value: 8 (0x00000008)
    //   
    //   public static final int NETWORK_TYPE_HSPA
    //   Since: API Level 5
    //   Current network is HSPA
    //   Constant Value: 10 (0x0000000a)
    //   
    //   public static final int NETWORK_TYPE_HSPAP
    //   Since: API Level 13
    //   Current network is HSPA+
    //   Constant Value: 15 (0x0000000f)
    //   
    //   public static final int NETWORK_TYPE_HSUPA
    //   Since: API Level 5
    //   Current network is HSUPA
    //   Constant Value: 9 (0x00000009)
    //   
    //   public static final int NETWORK_TYPE_IDEN
    //   Since: API Level 8
    //   Current network is iDen
    //   Constant Value: 11 (0x0000000b)
    //   
    //   public static final int NETWORK_TYPE_LTE
    //   Since: API Level 11
    //   Current network is LTE
    //   Constant Value: 13 (0x0000000d)
    //   
    //   public static final int NETWORK_TYPE_UMTS
    //   Since: API Level 1
    //   Current network is UMTS
    //   Constant Value: 3 (0x00000003)
    //   
    //   public static final int NETWORK_TYPE_UNKNOWN
    //   Since: API Level 1
    //   Network type is unknown
    //   Constant Value: 0 (0x00000000)

I would consider LTE to be 4G, but which of these are really considered 3G?
Anything else I would consider 2G.

So where do you draw the line between 3G or not 3G? 

Update:
I found another relevant answer at https://stackoverflow.com/a/8548926/949577
It uses ConnectivityManager() to get type and subtype and then classifies the subtype as either fast or not.
I don&#39;t know if using ConnectivityManager() is a better approach then using TelephonyManager () since they both appear able to return the network type.

Also I found a link that compares wireless data standards at http://en.wikipedia.org/wiki/Comparison_of_wireless_data_standards.
