Nokia Siemens Networks answer - Liquid Net: unleashing the
broadband opportunities of existing networks
What
Unleashes frozen network
capacity into a reservoir of
resources that can flow to
fulfill unpredictable demand
How
• Self-aware and self-adapting
• Software-defined applications on multi-purpose hardware
• Inter-linked architecture
• Evolutionary
Why
• Higher network utilization: Up to 65% capacity gain in radio cells
• Lower operating costs: Up to 15% core network savings through automation
• Superior customer experience: Streaming optimization can halve video standstills
• Business potential: Increase revenues by up to 10% with temporary
broadband upgrade

Liquid Radio: Baseband Pooling - static capacity becomes
fluid and adaptive
The challenges . . .
LTE-A
• The ‘ebb and flow’ of demand leaves capacity
LTE
stranded in conventionally dimensioned networks
• 2G, 3G, LTE and LTE-A coexist in the same sites
• Introducing small cells addresses just one aspect
of congestion – fronthaul, backhaul and core need
to be considered too
• Signal quality does not equal throughput and thus
QoS/QoE
