BackgroundSFR deployed UMTS and LTE over all RATP transport network in Paris, and shared with BYG/LotB/Orange. The network is
composed of 295 stations and 319 radio sites.
Challenges 5 bands and 4 operators sharing, Inter-modulation
rejection is the biggest challenge Tradition solution do not support evolution from 2G

Installation space is narrow, traditional solution is hard to update new band
