Why Should I Care About IP RAN Optimization?
Worldwide Global System for Mobile Communications (GSM)
and Universal Mobile Telecommunications Service (UMTS) mobile
wireless operators face multiple challenges and strong competitive
pressure and need solutions to reduce their operating expenses (OpEx)
while expanding their networks and providing new innovative services.
The Cisco® RAN Optimization solution helps mobile operators
address these needs. It optimizes GSM and UMTS traffic, reducing
the number of E1/T1 leased lines needed; allows easier network
expansion for increased traffic or UMTS deployment; and transports
IP traffic using recaptured bandwidth for innovative services at the
What Problems Need to be Solved?
Today’s competitive environment forces mobile operators to address
the following challenges:
• Reduce OpEx for higher operating margin
• Expand existing networks to support increase traffic and deploy
new technologies such as UMTS and high-speed downlink packet
• Differentiate from competition with innovative services
• Provide larger bandwidth for richer mobile data services
Cisco Systems offers a leading solution that provides an efficient,
scalable, and reliable answer for all these needs.
Cisco RAN Optimization
Cisco RAN Optimization solution optimizes GSM and UMTS traffic
at the cell site and enables end-to-end IP services, reducing OpEx,
increasing RAN efficiency, and delivering new revenue-generating
Cisco MWR 1900 Series mobile wireless routers compress and
optimize GSM and UMTS traffic, reducing leased line costs, and
using the recaptured backhaul bandwidth to transport IP data
services. The routers support traditional narrowband (T1/E1,
microwave) and high-speed (xDSL, WiMax, Metro Ethernet)
RAN backhaul networks, for scalability and cost reduction.
The Cisco MWR also provides aggregation and optimization services
for backhaul traffic at the core site. It connects multiple cell-site
mobile wireless routers to a base station controller/radio network
