he report, Emerging Markets Broadband Objectives: Spectrum Requirements, forecasts that approximately 90% of 5G cell sites in emerging markets will be operating support a combination of sub-6 GHz bands by 2026, with sub-6 GHz bands providing the best-in-class coverage while catering for sufficient capacity in emerging markets. Yet while millimetre-wave (mmWave), with its larger amount of bandwidth, can meet very high-capacity demand use cases, ABI believes that its poor propagation characteristics and cost of deployment puts it in 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,” explained Dean Tan, research analyst at ABI Research. “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.”
