France SFR: POI3401 Replaced Traditional POI In Paris Subway Background SFR 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 to UMTS and LTE
•
Installation space is narrow, traditional solution is hard to update new band
