IoT Solutions for Life-safety Applications

" summary

Claim: replace passive DAS with an active-active DAS (Tower Link) that uses existing fire alarm wiring so antennas become IP nodes. System uses G.hn over 2-hour fire-rated twisted pair, supports up to 24 devices per pair and shows 140 Mbps over 900 m in tests (spec 1.7 Gbps). A pilot has 16 nodes in one New York building and two warehouses with five nodes each. Edge runs in Docker but certification forces a watchdog that suspends IoT processing to preserve life-safety radio priority.
