Query: Demo Abstract: CDMA-based IoT Services with Shared Band Operation of LTE
  in 5G   With the vision of deployment of massive Internet-of-Things (IoTs) in 5G
network, existing 4G network and protocols are inefficient to handle sporadic
IoT traffic with requirements of low-latency, low control overhead and low
power. To suffice these requirements, we propose a design of a PHY/MAC layer
using Software Defined Radios (SDRs) that is backward compatible with existing
OFDM based LTE protocols and supports CDMA based transmissions for low power
IoT devices as well. This demo shows our implemented system based on that
design and the viability of the proposal under different network scenarios.
