To help you understand what 5G is, and what it means to you, we've put together a handy guide here.
What is 5G?
At its most basic level, 5G will be used to make calls, send texts, and to simply get online. But it's going to be significantly faster than previous generations, and could open the door up to a range of exciting new uses.
5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands are faster, they don't carry information as far. That's to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity(容量).
Why is it better than 4G?
5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver peak download speeds of around 300 Mbit/s. In real life, this could allow you to download a full HD film in less than 10 seconds!
It means there will be very little—if any—delay when you carry out tasks on a device. While this will help improve things like gaming experiences, it could also pave the way for safer self-driving cars—in which even a short delay could be life-saving.
Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.
A. How does 5G work?
B. How will 5G affect you?
C. 5G is also expected to have a lower latency (潜在因素).
D. 5G is short for "5th generation mobile network."
E. In comparison, 5G could offer download speeds of over 1 Gb/s.
F. Therefore, the similarity between 5G and 4G technology is huge.
G. This means 5G will support up to 1,000 more devices per meter than 4G.
