5G (5th generation mobile networks or 5th generation wireless systems) denotes the proposed next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G planning includes Internet connection speeds faster than current 4G, and other improvements. - Data rates of tens of megabits per second for tens of thousands of users
- 1 gigabit per second simultaneously to many workers on the same office floor
- Several hundreds of thousands of simultaneous connections for massive wireless ****** network
- Spectral efficiency significantly enhanced compared to 4G
- Coverage improved
- Signalling efficiency enhanced
- Latency reduced significantly compared to LTE.
The Next Generation Mobile Networks Alliance feels that 5G should be rolled out by 2020 to meet business and consumer demands. In addition to providing simply faster speeds, they predict that 5G networks also will need to meet new use cases, such as the Internet of Things (network equipment in buildings or vehicles for web access) as well as broadcast-like services and lifeline communication in times of natural disaster. Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities have been grouped under the current ITU-T 4G standards. Most telecom vendors expect 5G to offer the following performances: - Data rates up to 10 Gbit/s over the air.
- Latency in the order of 1ms
- Enable Internet of Things (IoT) devices to run on battery for up to ten years.
