● Local Aggregation of IOT nodes is done through:
○ Wifi
○ Zigbee / 802.15.4 / Dust / Z-Wave
● Site aggregation is done through 3G/4G/FTTx
● Need external power source for the aggregation
● Higher throughput
● High throughput, sending voice/video
● Real Time or near-RT
● In home, in plant, on campus.
