Abstract:

  The current report attempts to explore the top challenges that the MNOs need to overcome during 5G deployment in highly dense populated areas. Indicatively, the MNOs are warned about site acquisition challenges and electrification/energy related needs for a huge number of sites that shall be installed discretely at street level, the demand for rigorous testing and measurements to ensure full network coverage and always-on operation so that even mission critical applications (such as automotive and e-health apps) are enabled, accompanied by associated cost factors. Provided that at the time of writing (beg/2021) little is the worldwide experience from operating 5G networks, potential actions are suggested towards a smooth and efficient short time-to-market 5G deployment. In addition, indicative 5G densification related figures (e.g. amount of h/w nodes and distances among them), are calculated based on a specific FiWi PtMP network solution aiming at supporting the ultra-broadband 5G NR fronthaul bandwidth, while alleviating the need to install fiber terminations at every Base Station site.
