Nokia Networks is in talks with Indian telecom operators to start trials of next generation 5G networks even as the country is yet to see full-scale roll out of 4G technology based mobile voice and data services.
The Finnish telecom equipment maker is already testing the fifth-generation networks with global telecom giants like US-based Verizon, Korean SK Telecom and Japan's NTT DoCoMo. The 5G technology will guarantee delivery of 100 megabit per second speed at homes and will be capable of handling 1000 times more data traffic when it will be commercialised by 2020, Nokia Networks Head of Mobile Broadband Milivoj Vela said on the sidelines of an event Tuesday.
In India, Nokia Networks is part of Telecommunications Standards Development Society which is working on 5G, and is in discussion with telecom operators to start 5G trials.
However, Indian telcos are still investing in 4G technology to roll out the fourth generation networks and large parts of the country are yet to be covered under the high-speed data and voice services.
Talking about 5G networks, Vela said that 5G will focus on data services while voice calls will be facilitated through 4G technology.
"It will be used for purposes beyond voice and data communications carried by people today. It will has less than 1 millisecond latency that will be used by machines for quick action like for to stop in case it identifies any obstacle, surgery from remote location etc."
"Discussion about spectrum (at global level) in which 5G will operate will finish by 2019. Commercial 5G deployment will start in 2020. Then you will see 100Mbps guaranteed speed everywhere," Vela said.
He said that 5G will operate in spectrum band above 6000MHz and the technology will be launched in phases. "One cell (mobile antenna) in 5G will be able to handle 1000 times more data traffic in 2020 compared to data traffic in 2010. We have already achieved 1 million devices connected to single cell site and 30Gbps speed on 73GHz band in lab," Vela said.
At present spectrum band between 700MHz and 2.6GHz are available for mobile services in India. Wifi services are generally used between 2.4GHz to 5.9GHz.
"Already 4G is taking voice calling to high definition voice calls and voice call cannot be better than this. 5G will about high quality data experience. It will enhance telepresence (web conferencing) to a level where one will not feel the difference if a person is in room or on telepresence," Vela said.
