5G Deployment in India, Everything You Need To Know

The application of 5G is not limited to telecommunication but is much more profound in the field of internet of things (IOT) or machine to machine communication.

5G will come in handy for smart automobile, smart signalling and tracking for trains, delivery of goods by drones, 5G will revolutionise the field of medicine by provisioning robotic surgery from across the globe.

5G will be 100 times faster than existing 4G networks and will make gigabit speeds possible over wireless with peak speeds reaching 20 Gbps with latency dipping as low as 1 millisecond. 5G will allow streaming video in 8K resolution without buffering, it will provide for zero lag gaming with virtual reality and augmented reality headgear.

Frequency Bands for 5G

Department of Telecom (DoT) in India has allocated 100 MHz of spectrum between 3300-3400 MHz band and 175 MHz of spectrum between 3400-3600 MHz band for 5G deployment and this will be put up for sale in the upcoming auction which is scheduled to take place in the last quarter of the current fiscal year. Spectrum will be auctioned in block sizes of 10 or 20 MHz.

For future 5G needs, the government plans to carve out a 600 MHz band from the unused low band spectrum which has been vacated by Prasar Bharati (Doordarshan). Mid band spectrum in 1.4 GHz, 2.6 GHz and 4.8 GHz will also be opened up for 5G. High band spectrum in 26 GHz, 31 GHz and 47 GHz is also likely to be opened up for 5G as it can provide much more bandwidth than the lower frequency bands. E and V band spectrum in the range of 71-86 GHz and 57-71 GHz will be used as the fiber equivalent for the wireless network as backhaul frequency bands.

Various Challenges in 5G Deployment

5G networks are faster than 4G simply because they use much higher frequency bands for data transmission, 5G signal has millimetre-wavelength whereas in comparison 4G signal waves have a length of 30 to 40 cm, which means where a typical 4G tower can cover a 10 Km radius a 5G tower will only be able to cover a 300 metre radius. This means 5G networks would need a tower every few hundred metres, which would increase the cost of deployment and make this network feasible only in densely urban areas.

ISRO plans to use around 10% spectrum in the 26GHz band for satellite communication and to avoid interference from 5G networks operating in the same band it has convinced the DoT to force the telecom operators to power down the transmission of 5G signals from their BTS to merely 7 decibel watts (dbW) per 200 MHz of spectrum, reducing its coverage radius to 30 metres whereas the global standard is 33 dbW/200MHz which means the operators would need to erect many more towers to achieve the same coverage, which would increase cost of deployment by 4-5 times and make it commercially unviable.

TRAI recommended base price per MHz of pan India 5G spectrum is Rs. 492 crore whereas by global reference the price per MHz of 5G spectrum in countries like South Korea, Spain, UK, Italy is around Rs.84 crore. Apart from having to pay 5 times higher price for spectrum, Indian operators would further have to shell out heavy amounts of money for getting right of way from local authorities for laying fiber for backhaul for the 5G BTS. The operators would also need to pay the government for license fee and spectrum usage charge (SUC) in addition to hefty customs duty on import of telecom gear.
