What are potential drawbacks or limitations associated with relying heavily on ICAS for industrial scenarios

While ICAS offers significant benefits for industrial scenarios, there are potential drawbacks and limitations that need to be considered. One limitation is the complexity of integrating communication and sensing functionalities into a single hardware platform. This integration may lead to increased system complexity, higher power consumption, and potential challenges in managing interference between communication and sensing tasks. Moreover, relying heavily on ICAS for critical industrial applications introduces a single point of failure risk if the integrated system malfunctions or experiences downtime.
