Data analysis project:
Cellular operators work to recognize under-performing network layers or elements, with the aim of maximizing the efficiency of their networks. To fulfill this goal, cellular operators usually undertake detailed analysis on heterogeneous types of on-field collected network data, coming from different sources such as end users devices, base station counters, network probes, etc. Moreover, the collection of on-field measurements over large time periods (months or years) is crucial to recognize trends happening in the network.
In this project, we are interested in assessing the impact of the lock-down due to COVID-19 pandemic onto the network of a big Italian cellular operator. Exploiting the availability of network data relatively to the periods Before and During the lock-down, we are interested in investigating:
The variation of base stations traffic load, in terms of number of connections and downloaded data volumes,
The variation of RRC Setup and Re-Establishment Success Rates.
This analysis aims at understanding i) whether it is possible to differentiate (and recognize) residential and non-residential network areas, ii) whether the increase of residential connections and consequently the raising of connection hot-spots have lowered network performance, iii) possible action plans to improve network efficiency in serving connection hotspots.
- Participating to the project require signing a Non Disclosure Agreement (NDA)
- Individual participation or participation in teams of two students is allowed
- All teams will be assigned the same project and are expected to work independently
- Send an email with the name(s) and email(s) of team member(s) to prof. Capone.
- Get the data set and work on it focusing on one or more of the objective (be creative)
- Prepare a presentation of the work and send it to prof. Capone
- Deadline: June 4
- Folder with recent exams
