6G Mobile Communication System
6G frameworks will have reconciliation of 5G alongside satellite system. Taking after are the satellite frameworks created in various nations:
• GPS (by USA) only an idea, not reality
• COMPASS (by China)
• Galileo (by EU)
• GLONASS (by Russia)
It bolsters neighborhood vocie scope and different components.
7G Mobile Communication System
The 7G system will be same as 6G. Moreover 7G characterizes satellite functionalities in remote portable correspondence. This will give numerous elements and deal with every one of the downsides of past era of portable remote correspondence frameworks. The main consideration here will be expense of telephone call and different administrations. It gives consistent development of cell telephone from one nation to the next. This will be significant advantages for successive worldwide explorers.
