How does 4G network work?

How does 4G work? 4G works much in the same way as 3G, simply faster. Using high-speed download and upload packets, 4G allows you to access broadband style speeds whilst away from your Wi-Fi . Users can often access speeds of up to 21Mb on the go, but this is, however, affected by location.

4G (LTE), like all other radio communications standards, is based on the use of radio waves or radio frequency (RF) energy to transmit and receive voice and data calls.

LTE transmits data by dividing it into slower parallel paths that modulate multiple subcarriers in the assigned channel . The data is transmitted in segments of one symbol per segment over each subcarrier. Data to be transmitted is allocated to one or more resource blocks (RBs).
