Libya Large Scale Commercial Application
1.8 Million lines GSM network, MSS adopted ZTEs
WCDMA R4 CN based on V3 platforms, finished at the
end of 2005.
1 Million lines WCDMA, covering the capital, Tripoli and
the other 13 main cities, can serve 90% of the population
in Libya.
Fast growth of subscriber: The number of subscribers
broke through 300,000 at the end of 2006.
Network Scale
R4 architecture; GSM and WCDMA hybrid network;
support 2G/3G handover and roaming
Both Pre-paid and Post-paid services are available
Thousands of dual mode mobile subscribers can
smoothly migrate to 3G network
Within 3 months, finished the construction and
optimization of 1.1 M lines 3G network
HSDPA in scale application, smoothly evolve to HSPA+
Speciality
one of the few profitable
