When it comes to auctioning spectrum licenses, I see that spectrums 10MHz wide seem to fetch higher prices (i.e. in South Africa at least - https://www.biznews.com/sa-investing/2020/12/24/telkom-sues-icasa).
According to that article, the licensing condition of the 800MHz spectrum 10MHz wide carries the obligation of 99.8% coverage of the population.
What data throughput speeds does this theoretically support? What is the difference between spectrum allocations 5MHz wide vs 10MHz wide in this regard?
