SingleDAS Help Azercell Enhance Brand in Crystal Hall Backgroud

Crystal Hall

Crystal Hall , the biggest theater in Azerbaijan, Total seats are 25000 . There are many VIP mobile customers. •

Azercell mobile market share: 60%, 3G subscriber rate:90%, but have no coverage in Crystal Hall

•

High complaint rate

Challenge •

Equipment footprint is limited ,difficult to deploy E// Marco BTS equipment

•

1800MHz LTE evolution demand, but it is too hard to get the authorization to rebuild system.

Benefit •

One set of equipment support multi-system ,fast deployment

•

High output power(40W per band) make less equipment, easy deployment

•

One deployment support capacity flexible scheduling and LTE evolution ,reduce CAPEX

•

Excellent coverage (RSCP>–95dBm : 100%, Ec/Io>–7dB : 99%), reduce subscriber rate

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
