AVD network speed 본문
For Mobile Data Link I am afraid that you can only check TelefonyManager.getNetworkType() to determine the current Mobile Data Link type. You should then aproximate to actual speed by link type (i.e. for GPRS up to 128 kbps, for EDGE up to 236.8 kpbs, for 3G up to 2 Mbps, for HSDPA up to 7.2 Mbps). Take into consideration that this is only an aproximation. Your could be conneting using HSDPA but your carrier limiting the top speed to 2 Mbps
Theoretical maximum speeds of 4G LTE reach 100Mbps... However, actual performance of mobile data is much lower, considering signal strength, frequencies used, congestion, etc.
Here are the real-life speed ranges of the various mobile wireless strandards commonly used in the US today:
GSM (Global System for Mobile Communications) 2G -- 9.6Kbps
GPRS (General packet radio services) 2.5G -- 35Kbps to 171kbps
EDGE (Enhanced Data rates for GSM Evolution) 2.75G -- 120Kbps to 384Kbps
UMTS (Universal Mobile Telecommunications System) 3G -- 384Kbps to 2Mbps
HSPA (software upgrade to UMTS, theoretical 42Mbps) 3.5G -- 600Kbps to 10Mbps, averages 1-3Mbps
WiMAX/LTE "4G" (theoretical 100Mbps) -- 3Mbps to 10Mbps average, 20Mbps+ peak download speeds.
