5G simply stands for fifth generation and refers to the next and newest mobile wireless standard based on the IEEE 802.11ac standard of broadband technology. The next (5th) generation wireless network will address the evolution beyond mobile internet to massive IoT (Internet of Things)in 2020. Achieving the 5G vision will require new technology innovations that deliver unparalleled levels of scalability, capability and efficiency.
- 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
5G networks expand broadband wireless services beyond mobile Internet to IoT and critical communications segments.Current 4G mobile standards have the potential to provide 100s of Mbps. 5G offers to take that into multi-gigabits per second. It will have faster download speeds and the ability to run more complex mobile Internet apps.
It’s not just about speed in network connection either 5G is seen as the underlying technology allowing self-driving cars to talk to each other, or for people to wirelessly stream super high-definition virtual reality content into their headsets.
All cellular networks use spectrum in lower frequency bands like 700 megahertz. The high speed 5G network uses a high frequency spectrum for which the millimeter wave range falls between 24 gigahertz and 100 gigahertz.
Latency is the response time between a click action and its response from the network. In current networks the lag time may be around 20 milliseconds. With 5G that latency gets reduced to 1 millisecond.
Wireless carriers can take different bands of radio frequencies and bind them together. They can choose the speediest and least congested Carrier.
Currently our networks using licensed spectrum but in 5G it will use unlicensed spectrum so that they can maintain enough coverage. This can increase the access network capacity and benefit users’ wireless experience.
In 5G a single physical network will be sliced into multiple virtual networks that can support different devices. Same tower can offer low power connection as well as faster,low-latency connection at the same time.
5G in India:
Airtel and Huawei have successfully conducted India’s first 5G network trial. India plans to roll out 5G services for consumers by 2020.
Before the 5G network get launched in India, many smart-phones have hit the market with the feature to support a 5G Sim.
