- In telecommunications, 4G is the fourth generation of mobile communication technology standards.
- A 4G system provides mobile ultra-broadband Internet access.
- Connection speed depends on location and number of people online.
- Average download speeds are more than 3 times faster than 3G.
- Average upload speeds are over 10 times faster than 3G.
- 4G is more consistent during travel when user location is constantly changing between towers: Users can access increasingly information-heavy applications, such as high quality video content and real time video chat.
Networks must meet these standards to be considered 4G
- Set by: International Telecommunications Union-Radio Communications Sector (ITU-R).
- Must be based on all Internet Protocol (IP) packet switching instead of circuit-switched technology.
- Must use OFDMA multi-carrier transmission methods or other frequency-domain equalization (FDE) methods instead of current spectrum radio technology.
- Must have peak data rates close to 100 megabit per second for a user on a highly mobile network.
- Must be able to offer smooth handovers across differing networks without data loss.
