Today’s Radio Access Networks

The RAN is mobilewireless operators’most valuable asset

Approx 70% of CapEx

Typically RANs account for largest operating expense of the network

Yankee Group reports that backhaul amounts to approximately half of technical OpEx

RANs are prime for optimization

• 50%+ measured eff gain on GSM and UMTS

• No change to RAN backhaul design

• Single IP backhaul network serves 2G/3G/4G

• RAN backhaul overany network

• Offload bandwidth hungry HSPA and UMTS data

• Simple network expansion

• Intelligent cell site IP enables new revenue generating services

• Remote cell site management andLAN extension

• Seamless expansion to 4G

Cisco removes redundant and other unnecessary information from idle sub-rate DS0s, TRAU frames, and signaling frames

2Cisco inspects ATM headers and payloads, suppresses select header bytes, payload bytes, and other overhead

Cisco multiplexes optimized TDM and ATM traffic into IP packets for transport acrossthe backhaul network

• 2G: 50% measured eff gain

• 3G: 15–90% measured eff gain

IP transport further increasescall capacity using statistical multiplexing

MLPPP optimizes bandwidth utilization and enhances reliability

QoS and dynamic bandwidth sharing across radios and traffic classes efficiently support multiple traffic types on common network
