Reading the new CNAF (Cuadro Nacional de Atribución de Frecuencias) as “there are now 400 MHz available for private 5G networks” would mean stopping at the headline.
Within the 3.8–4.2 GHz band, the CNAF establishes different frequency ranges, uses and access models. For example, 3.8–3.92 GHz is allocated to local connectivity under licensed and self-provisioned models; 3.92–4.02 GHz includes Defence uses; and 4.02–4.12 GHz is allocated to local connectivity under self-provisioning. In addition, part of the 3.92–4.12 GHz range may also be used for electronic news gathering.
What does this mean for a real project?
The question is no longer simply whether a company can consider deploying a private 5G network.
It is also necessary to determine which spectrum scenario fits the use case, under which access model, and what implications that choice has for the network design.
Because spectrum cannot be separated from engineering decisions: frequency, power, environment, coverage requirements, interference and deployment architecture all influence which solution is technically viable in each scenario.
This is where APTICA can add value.
We analyse project requirements, assess radio feasibility, simulate coverage and interference scenarios, evaluate design alternatives and dimension the required infrastructure before deployment decisions are made.
The new CNAF expands the possibilities.
Turning those possibilities into a technically viable network requires understanding which option actually makes sense for each project.
If you are evaluating a private 5G network or want to assess which options fit your scenario, get in touch and we will review it with you, with no obligation.
