Fifth-generation wireless, or 5G is the fifth generation of cellular mobile communications, engineered to greatly increase the speed and responsiveness of wireless networks.
It is assumed that 5G networks will not become commercially available until the 2020 timeframe.
The International Telecommunications Union (ITU) will be the standards body that releases the final standard, which is also being referred to as International Mobile Telecommunications (IMT)-2020.
The 3GPP is the mobile industry standards body that will submit a proposed specification to the ITU to be part of the IMT-2020 standard. Mobile operators and vendors all participate in the 3GPP specification process.
5G technology is driven by 8 SPECIFICATION REQUIREMENTS
- Up to 10 Gbps data rate – > 10 to 100x improvement over 4G and 4.5G networks
- 1-millisecond latency
- 1000x bandwidth per unit area
- Up to 100x number of connected devices per unit area (compared with 4G LTE)
- 99.999% availability
- 100% coverage
- 90% reduction in network energy usage
- Up to 10-year battery life for low power IoT devices
Fifth-generation wireless, or 5G, is the latest iteration of cellular technology, engineered to greatly increase the speed and responsiveness of wireless networks. With 5G, data transmitted over wireless broadband connections could travel at rates as high as 20 Gbps by some estimates — exceeding wireline network speeds — as well as offer latency of 1 ms or lower for uses that require real-time feedback. 5G will also enable a sharp increase in the amount of data transmitted over wireless systems due to more available bandwidth and advanced antenna technology.
In addition to improvements in speed, capacity and latency, 5G offers network management features, among them network slicing, which allows mobile operators to create multiple virtual networks within a single physical 5G network. This capability will enable wireless network connections to support specific uses or business cases and could be sold on an as-a-service basis. A self-driving car, for example, would require a network slice that offers extremely fast, low-latency connections so a vehicle could navigate in real time. A home appliance, however, could be connected via a lower-power, slower connection because high performance isn’t crucial. The internet of things (IoT) could use secure, data-only connection
What is the status of 5G deployment?
Wireless network operators in four countries — the United States, Japan, South Korea and China — are largely driving the first 5G buildouts.
Network operators are expected to spend billions of dollars on 5G capital expenses through 2030, according to Technology Business Research Inc., although it is not clear how 5G services will generate a return on that investment. Evolving use cases and business models that take advantage of 5G’s benefits could address operators’ revenue concerns.
Bharti Airtel and Chinese telecom gear maker Huawei have successfully conducted India’s first 5G network trial under a test setup at the former’s network experience centre in Manesar, Gurgaon.
Abhay Savargaonkar, director – networks at Bharti Airtel, said the test is a small but significant step in its journey towards next generation 5G mobile networks, which could offer data speed up to 100 times faster than current 4G networks. “The promise of 5G is endless; it will be a game changer, and it will change the way we live, work and engage,” he said. “We look forward to working closely with our partners for developing a robust 5G ecosystem in India.”
India plans to roll out 5G services for consumers by 2020 and to achieve that objective, the government had in September this year set up a high-level forum that will evaluate and approve roadmaps and action plans to bring in the latest technology.
