6 GHz spectrum vital for super-fast 5G speed: COAI

It is critical to identify 6 GHz band for international mobile telecommunications (IMT) services, to aid long-term network planning and help the National Broadband Mission achieve broadband speeds up to 50 mbps by 2024-25, the Cellular Operators’ Association of India (COAI) said.

6 GHz is the last mid-band opportunity offering a provision of minimum 2 GHz contiguous mid-band spectrum, which will become critically essential for mobile communications beyond 2025.

“Since mid-bands offer wide coverage and capacity, they are critical for cost-efficient deployments of 5G mobile networks. This is established by the fact that out of the 176 global 5G networks rolled out, around 70 per cent (120 networks) have harnessed mid-bands,” COAI Director General SP Kochhar said.

A GSMA report shows that in the absence of the required additional mid-band spectrum, the mobile networks would need to be substantially densified by increasing the number of base stations to deliver 5G data rate targets.

If telecom service providers (TSPs) don’t do so, 5G download speeds would be reduced to 50 percent if less spectrum is allocated in the 6 GHz band, or 80 percent if only 700 MHz band is allocated to IMT, compared to an assignment of 1.2 GHz.

“It may also lead to deterioration of the 5G experience, which would negatively impact its adoption and eventually create risks to investments in next gen infrastructure.”

In case adequate spectrum in the 6 GHz band is not allocated to IMT, India would have to account for around 60 per cent higher annual costs to achieve the performance expected from 5G services, and this would lead to delayed expansions and a significant increase in energy consumption and radio network cost.
