How 6G will work?

The exact workings of 6G are still being figured out because the specifications haven’t been finalized by the (International Telecommunication Union) ITU yet. However, based on what we know from previous generations of cellular networks, there are some main things the sixth generation will likely do:

1. Using Unused Spectrum:

Engineers are looking into using high frequencies for 6G, way beyond what 5G uses. There’s a lot of unused spectrum in these high frequencies that could let us transfer data super-fast.

2. Making Spectrum Use More Efficient:

Right now, wireless devices can either send or receive data on a certain frequency at one time. 6G might be able to improve this by using fancy math to send and receive data on the same frequency at the same time, making things faster and more efficient.

3. Mesh Networking:

Instead of just connecting to cell towers like in 5G, 6G might let devices act like mini cell towers themselves. This means devices could help each other out to expand coverage and make the network stronger.

4. Using a New Kind of Internet Protocol (IP):

 There’s talk of 6G using a new version of the Internet Protocol (IP) to move data around. This new IP would be like a super-fast delivery service for data, making things even quicker and more reliable.

5. Smart Use of Frequencies:

6th generation will be smart about which frequencies it uses, adjusting wavelengths to avoid interference. This is based on the idea that different materials absorb and emit electromagnetic radiation at specific wavelengths, so 6G will take advantage of that to make sure signals get through without any problems.
