5G stands for “fifth generation” cellular communication where “G” is used to describe the generations of cellular device communication technology. The next-generation of telecom networks (fifth generation or 5G) have started hitting the market end of 2018 and will continue to expand worldwide. One of the most important elements of 5G technology includes expanded use of MIMO (multiple inputs, multiple outputs) antenna arrays, sophisticated implementation of beamforming technology to transmit signals more directly to end users5G is expected to unleash a massive IoT (Internet of Things) ecosystem where networks can serve communication needs for billions of connected devices, with the right trade-offs between speed, latency, and cost.
Up to 10Gbps 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)
100% coverage
90% reduction in network energy usage
Up to 10-year battery life for low power IoT device
In India, 5G network will be provided under different frequency bands under 1 GHz, offering longer range but lower speeds; mid-band up to about 6 GHz, offering similar range to 4G but at higher speeds, and so-called millimetre-wave offering the very highest speeds in frequency bands at 20 GHz or higher.
How fast it is?
5G network achieves the highest speed of 10 Gbps. It is 10 to 100 times faster than the 4G network.
But how?
According to a basic law in the communication science "the shorter the frequency, the larger the bandwidth". The use of shorter frequencies which is millimetre waves between 30GHz and 300GHz for 5G networks which is the reason behind this.
Latency
This can be defined by the time it takes for a request to travel from the sender to the receiver and for the receiver to process that request. or simply the round trip time from the browser to the server. It determines how fast the contents within a pipe can be transferred from the client to the server and back.
5G provides a very low latency rate. In a 4G network, it is about 200 Milliseconds but in 5G it is as low as 1 millisecond. (1 millisecond = 1/1000 of a second)
Its application is in self-driving cars require fast response time ( very aggressive latency) while they do not require fast data rates.
The Telecom Regulatory Authority of India (TRAI) has said that spectrum for 5G network is made available for 5G services in the 3300 to 3400 MHz and 3425 to 3600 MHz bands. Ericsson, a network equipment vendor based in Sweden, has said 5G service is likely to be available in India only from 2022.
Get ready for a new speed!
