December 2015 Systemics-PAB performed independent measurements of quality of mobile networks in Poland. The contract was assigned by the Office of Electronic Communication (UKE- Polish Regulator) in order to deliver the information on service quality to the public based on the fair assessment. The intention was to do a survey that can provide the results as close to user experience as possible on representative territory of Poland.
Measurements where done in all cities above 50k inhabitants (close to 100 of such places) totalling with over 20000 km of drivetested roads in more than 450 hours. Results showed that the overall services of voice calls in mobile networks are of similar quality for all operators: Orange, T-Mobile, Polkomtel and Play. Calls are compiled in a short time and picked rarely (less than 1% of calls). More varied results were obtained for data services. Full report is available in Polish at the www.uke.gov.pl
