Based on findings from its new report, Emerging Markets Broadband Objectives: Spectrum Requirements, global technology intelligence firm ABI Research forecasts that approximately 90% of 5G cell sites in emerging markets will support a combination of sub-6 GHz bands by 2026. Sub-6 GHz bands will provide the best-in-class coverage while catering for sufficient capacity in emerging markets.
While millimeter-wave (mmWave), with its larger amount of bandwidth, can meet very high-capacity demand use cases, its poor propagation characteristics and cost of deployment put it at a disadvantage compared to sub-6 GHz bands for 5G deployment.
"5G mmWave will have its role to play in urban and suburban downtown locales in developed markets and perhaps commercial business districts in emerging markets but the reality is, emerging market telcos will need the coverage and capacity characteristics of the sub-6 GHz bands for 5G. Not only does sub-6 GHz has sufficient capacity to meet demand, but also can propagate over a longer distance and is not attenuated by rain," explains Dean Tan, Research Analyst at ABI Research.
What did ABI’s research show?
In a spectrum survey of 32 emerging markets conducted by ABI Research, at least 50% of countries will have allocated the low band (<1 GHz) spectrum for 5G while about 87% of countries will have allocated the mid bands (1 GHz to 6 GHz) by 2023. This stands in contrast to 34% and 12% countries for 26 GHz and 28 GHz bands respectively by 2023. For any market, it is fundamental that end-users have affordable handsets for a whole range of disposable income profiles.
ABI says that in emerging markets, it is important that smartphone sales can be sustained at about US$100 to increase inclusivity. While there will be disposable income strata that can afford multi-band/mmWave handsets, the reality is handset vendors will need to focus on the sub-6 GHz bands to keep the bill of material costs down. 5G handsets shipments, in emerging markets, supporting the sub-6 GHz band is expected to grow to nearly 600 million by 2026 at a CAGR of 22.7% from 2020.
"It is important for mobile operators to leverage globally harmonized spectrum bands as it provides economies of scale for the solutions, especially for markets where the average ARPU per month can be below US$10. In Nigeria, Airtel's monthly ARPU is about US$3.6, while for Jio in India it is US$1.93. Mobile operators in the emerging markets need to identify the optimal spectrum deployment strategy to meet their mobile broadband requirements," concludes Jake Saunders, Vice President, APAC, at ABI Research.
