How do you design a wireless sensor network for industrial process monitoring?

Industrial wireless network design: Select protocol (WirelessHART or ISA100.11a for process, WiFi/5G for high-bandwidth), perform site survey for RF coverage and interference, design mesh network topology with adequate redundancy (multiple paths to gateway), determine battery life requirements (update rate, transmit power), specify intrinsic safety ratings for hazardous areas. Address: coexistence with other wireless systems, cybersecurity (encryption, authentication), data latency requirements, and integration with existing DCS/SCADA. Typical applications: equipment monitoring, remote tank gauging, environmental monitoring. Define KPIs: network reliability, latency, and battery replacement frequency.
