A 4G internet speed test is a way to measure how fast the download and upload speeds of your connection are. In order to take a 4G internet speed test, you need to have a compatible 4G phone and a broadband internet connection. A high 4G internet speed will allow you to stream HD video and access the web faster than with a 3G or 2G connection.
The different types of wireless antennas affect how well your device can connect to the 4G network. Antenna type has very little impact on voice activity, but can make significant differences in data transfer rates when connected to a 4G network. For example, an indoor antenna will produce better download speeds than an outdoor antenna because the indoor antenna sends the signal further into buildings.
