“4G and 4G evolution is what is getting them [telcos] revenue today and for future they need to prepare for 5G. We have also been doing some technology and solution workshop with them to guide them how to evolve their network and prepare for 5G…5G will happen in line with the global timeline,” Radhey Shyam Sarda, Senior Solutions Director, Huawei Telecommunications, told ET.
He said that some services that 5G will power are already being introduced to market through LTE-A technology.
Huawei’s director, marketing and integrated solutions, Chandan Kumar said that the country is very much in line with the global roadmap. “Once we have agreements with the stakeholders to do some trials in India, I think maybe next year we can see some trials happening,” he said, adding that pre-standard trials can happen anytime.
Fifth-generation (5G) technology is expected to be used for a host of services, such as machine-to-machine communication, Internet of Things and even connected smart cities.
The Indian government has already started work to introduce 5G technology in India. The telecom department recently asked the telecom regulator to suggest the starting price for 5G airwaves, which could make their debut in the next sale, as well as 4G bandwidth. ET recently reported that department wrote to the Trai to set the reserve price for airwaves in the 4G bands of 700 MHz, 800 MHz, 1800 MHz, 2300 MHz and 2500 MHz, and for spectrum in the 3400 MHz to 3600 MHz bands that are used for 5G services.
Huawei’s Kumar however said that spectrum in bands like 1800 and 900 Mhz can also be used for 5G. “5G is targeting all spectrum access — millimetre wave band, and spectrum above 3 GHz and sub-3 GHz band– every band will have a different role in the networks,” he added.
Sarda said that C band and millimeter wave are getting more traction due to ready business case globally.
“Millimetre wave band will be used for hotspot capacity and will complement FTTx. It will also be used for cell backhauling of 5G nodes. Then comes the C band or 3.5 GHz band will be the capacity layer because in 5G if you want to give very good user experience. C band will drive enhanced mobile broadband and then IoT, like lot of video surveillance and other use cases,” he added.
The executives said that backhaul needs to be strengthened before the introduction of 5G in India, besides making network digitized with the introduction of cloud.
“Network cloudification, operations cloudification and service cloudification, all three aspects need to be addressed. Then only the full-fledged utilization or full-fledged deployment of 5G will happen,” Kumar said.
According to the executives, the implementation of 5G will require engagement with different stakeholders from other industries that were earlier not a part of the eco-system. They added that 5G will address the needs of new stakeholders and he network architecture must be entirely different. “For India, now is the time for us to prepare.”
