France SFR: POI3401 Replaced Traditional POI In Paris Subway

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

(28)

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

• One system support 5 bands and 4 operators
