我的应用程序上有一个指示器来显示网络类型(2G或3G或4G),但是获得网络类型后,我如何知道它应该属于哪个速度类别?
我知道如何检测网络类型:
private TelephonyManager telephonyManager;
telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
CurrentNetworkType = telephonyManager.getNetworkType();
给定可能的返回值:
// 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)
我认为LTE是4G,但其中哪些真正被视为3G?我还会考虑2G。
那么,您在3G与3G之间的界限如何?
更新:我在https://stackoverflow.com/a/8548926/949577找到了另一个相关的答案。 它使用ConnectivityManager()来获取类型和子类型,然后将子类型分类为快速还是不快速。我不知道使用ConnectivityManager()是否比使用TelephonyManager()更好,因为它们似乎都能够返回网络类型。
我还在http://en.wikipedia.org/wiki/Comparison_of_wireless_data_standards找到了一个比较无线数据标准的链接。
