Spatial and Temporal Multiplexing
Spatial muxing: Decrease resource sizing expecting smaller set of sources to be active at any time instant.
- Cost: call-blocking (time)
Temporal muxing: even if many are active at any particular time instant, expect that the average over time will be much smaller.
- Cost: buffers and meta-data (headers) in packets (space).
Note: We need packet switching to exploit both spatial and temporal gains.
