Each generation of wireless cellular technology has introduced increased bandwidth speeds and network capacity. 4G has speeds of up to 150 Mbit/s download and 50 Mbit/s upload, whereas 3G had a peak speed of 7.2 Mbit/s download and 2 Mbit/s upload. [3] 4G is not backward compatible with 3G due to significant differences in network architecture ...
Peak download rates up to 299.6 Mbit/s and upload rates up to 75.4 Mbit/s depending on the user equipment category (with 4×4 antennas using 20 MHz of spectrum). Five different terminal classes have been defined from a voice-centric class up to a high-end terminal that supports the peak data rates.
