Cellular networks have changed significantly since the introduction of first-generation cellular services that can only carry voice calls. Current generation cellular networks (4th generation or 4G) can handle the high-speed data required for multimedia streaming and provide basic network operations such as voice calling, messaging, and web browsing. However, with changing connectivity requirements, increased mobile data traffic, and new categories of connected ecosystem products, you can deliver even faster data speeds with lower latency, improve throughput, and get more concurrent connections. We need a new generation of cellular networks that will enable us. interference. And that's all about 5G telephony.

As the name implies, 5G is the 5th generation cellular technology. It is designed to improve network connectivity by addressing older speed, latency, and utility issues that previous and current generation cellular networks could not solve. 5G is said to provide 100 times the data speed of 4G networks. The key is to transfer data almost instantly with a network delay of less than 10 ms. It also improves throughput because it handles more concurrent connections than current generation networks.

Worldwide, 5G network offerings are rapidly evolving from testing to early commercialization. In India, network operators such as Airtel, Vodafone Idea and Reliance Jio have already partnered with providers such as Ericsson, Huawei and Samsung for testing planned by the end of this year before the service launches in 2020. doing.

For the first time, the Government of India has made the spectrum available to carriers for six months of testing. This was done to help national telecommunications companies prepare networks for 5G and develop India-specific 5G use cases. Indian service providers have conducted 5G testing nationwide, but 5G itself has been adopted for at least a year and no more.

The delay in the spectrum auction is especially problematic for Reliance Jio, which plans to sell its in-house developed 5G solution to the global market. The service provider planned to bring the solution to market after a major deployment in India. While Jio tests the solution in India most other service providers will have already adopted 5G.

The GSM Association, a trading organization that represents the interests of mobile network operators around the world, has made the following progress in terms of 5G in India.

Bharti Airtel and Huawei successfully conducted India's first 5G network test. Using a test setup at Airtel's Network Experience Center in Manesar, Gurgaon, we achieved user throughput in excess of 3 Gbit / s. Bharti Airtel has signed a Memorandum of Understanding (MoU) with Nokia and Ericsson to help prepare for 5G deployment.

Vodafone Idea also proposes 5G testing with multiple vendors such as Huawei and Ericsson.

Samsung will be working closely with DoT on 5G field testing in New Delhi in 2019. The company could also be one of the partners of Reliance Jio in the 5G field trial.

BSNL has signed an agreement with Ciena to conduct a field trial with the aim of commercial launch by 2020. Ciena and BSNL will jointly evaluate transport-based use cases and scenarios on a fronthaul, midhaul, and backhaul basis to consider resilience requirements and delay issues.
