4G Wireless Networks: Data and Bandwidth Improvements How much faster is 4G compared against 3G? The speed of 3G networks depends on how they are implemented. By 2010 Verizon (a CDMA network) had reached the limits of its 3G network speed in the United States. 4G networks allowed Verizon the ability to offer transmission speeds up to four times faster than its current 3G network. AT&T’s 3G network‚ however‚ is based on GSM. The GSM design left AT&T room to upgrade its current 3G speeds
