Similarity 66
Cat6A Structured Cabling
Augmented Category 6 structured cabling — 10 Gbps over the full 100 m channel, rated for 25 years of service. The default for any new commercial or premium-residential cabling layer.
Similarity 40
Hospital ELV Stack
Clinical-occupancy ELV coordination — fire-alarm, nurse-call, medical-gas alarm, access-control, IP-CCTV and BMS converging on a cause-and-effect supervisory matrix with NABH pressure-boundary discipline and OT-anaesthesia acknowledgement-delay tiers.
Similarity 28
Power over Ethernet (IEEE 802.3)
IEEE-standard delivery of low-voltage DC power over the same Cat-class cable as data. PoE+ delivers up to 30 W; PoE++ Type 3/4 up to 90 W — sufficient for IP cameras, APs, VOIP phones and small displays.
