Nokia Delivers 5G Deployment Directions
Following studies on dense deployments in Madrid and Tokyo, Nokia has released ten deployment recommendations (you can see them listed at the bottom of this post) for 5G that it believes will ‘provide the required capacity and end user data rates that will be needed’.
“LTE Advanced will be sufficient to provide the required capacity … for 2020”
With mobile data traffic already doubling every year, Nokia justifies the evolvement towards 5G with the need for more capacity. This need will demand more spectrum at higher carrier frequencies, for which Nokia recommends approximately 1 GHz of aggregated spectrum to provide the required capacity and cell edge data rates by 2030. In higher frequency bands, it believes that very large antenna arrays can be utilised to compensate for the higher path loss.
According to Nokia, the deployment of small cells using 5G frequency bands with an LTE macro/HetNet overlay will also be useful to meet capacity needs. It outlines that LTE Advanced will be sufficient to provide the required capacity of tens of Gb/s/km2 for 2020.
“multi-connectivity … significantly boosts cell edge performance and can lower the required density for small cell deployment”
However, the Finnish company makes the case for the deployment of 5G small cells in the 6-30 GHz band (cmWave) with a 500 MHz carrier bandwidth for 2025, and moving into 2030 it argues deployment up to 100 GHz band (mmWave) with 2 GHz carrier bandwidth will provide an appropriate Tb/s/km2.
It claims that multi-connectivity between LTE-A, cmWave and mmWave ‘significantly boosts cell edge performance and can lower the required density for small cell deployment’. In terms of cell edge data rates going into 2030, Nokia identifies the need for a 5G wide area solution.
“Nokia studies have shown that a 10,000-fold capacity can be provided in a dense urban environment as well as indoor dense areas”
Other recommendations included using mmWave to further provide backhaul to the small cells in a mesh configuration with a maximum of two hops, an inter-site distance of 75-100m to provide full coverage and satisfy capacity for both cmWave and mmWave deployments, as well as dedicated indoor small cell deployments to satisfy indoor capacity requirements beyond 2020.
‘Nokia studies have shown that a 10,000-fold capacity can be provided in a dense urban environment as well as indoor dense areas,’ claimed a spokesman.
