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
