Estimating the mid-band spectrum needs in the 2025-2030 time frame

In terms of the calculations, the value represents the proportion of the population which demand 100 Mbit/s in the downlink and the proportion of the population which demand 50 Mbit/s in the uplink during the busy period. [...] Therefore, a key factor in driving the demand for capacity is the vision that 5G should provide the 100 Mbit/s user experienced data rate in the downlink and 50 Mbit/s in the uplink (for simplicity, we will refer to these throughput requirements as 100/50 Mbit/s requirement in the rest of the report) anytime, anywhere and while “on the move”. [...] The advantage of focusing on the 5G The advantage of focusing on the 5G requirements is that the model is easy to validate requirements for a minimum data rate as it relies on a small number of key assumptions around typical cell sizes and average is that the model is easy to validate spectral efficiencies that are representative of future 5G deployments. [...] In principle, other things being equal, the higher the density, the greater the demand per km2 and consequently the higher the population density the greater the need for additional mid-band spectrum. [...] 3.3.3 The area traffic capacity supply side – key assumptions The variables in the city capacity supply per km2 availability model are: The number of macro cell sites per km2, driven by the inter-site distance; The role of mid-band outdoor small cells; Base station design margin; The site sectorisation; The spectral efficiency; and The amount of existing spectrum and additional spectru.
