Liquid Radio: Baseband Pooling - static capacity becomes fluid and adaptive
The challenges . . .
• The ‘ebb and flow’ of demand leaves capacity 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

The challenges . . .
High complexity
• Multi-RAT, multi-layer, multi-vendor• Thousand of multiple variables• Increasing level of expertise required by
systems demands more human interaction• Introduction of smaller cells into already
complex network environment• Capacity in the right technology layer• Challenging interoperability

Liquid Radio: GSM Software SuiteMaking network resources fluid for multiradio re-farming
Capacity demand is like a wave in radio networks
GSMHSPA /
LTE
Add more RF units, split BTS sites, create micro
layersHW
• More bandwidth for 3G HSPA / LTE• One more carrier for GSM with limited spectrum• More RF power for 3G HSPA / LTE
SW Activate Liquid Radio GSM Software Suite
GSM Software suite
Liquid Radio GSM Software Suite features:• Flexible MCPA Tx power pooling• Orthogonal Sub-channel (OSC)• Smart Resource Adaptation (SRA)• Dynamic Frequency and Channel Allocation (DFCA)• Precise Paging (PP)
Key financial benefits:• 20% lower Total Cost of Ownership (TCO)• 30% more GSM spectrum can be allocated to 3G HSPA/LTE
Key operational benefits• Same GSM service in reduced spectrum• Fluidity of multi-radio resources• Doubled 3G HSPA/LTE data throughput with less hardware• Easier spectrum re-farming to 3G HSPA/LTE

SON for Core self-optimizes and self-configures core networks key operational processes, e.g. by• automated traffic load balancing• optimized transport capacity distribution
SON for Core evolves to automated management for allocating resources from a virtualized core to different core applications
Proactively detect, analyze and react to changes in traffic demand and network conditions
• Prevents bottlenecks and traffic loss
• Highest utilization of investments
• Higher operational efficiency
• Improved network stability
