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

to UMTS and LTE

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


Huawei Value

Low PIM(-160dBc) and high isolation(in-band: 30dB; out-band:80dB) reduced interference, protect investment

Modularized design, new module is added on

the top to update LTE, no need redundant space

Idler wheel design makes installation easy and

fast, improves efficiency
