Multipoint geometries can create ground loops. ANSI/TIA-322 specifies how to bond shields and grounds in branched configurations to prevent noise and electrical hazards.

“TIA-322 replaces the star topology.” Fact: The standard explicitly states that multipoint geometry is supplemental to star topology, suitable for specific applications like hotel room TV distribution, stadium seating sections, or industrial control loops.

TIA periodically revises standards. Ensure you are purchasing the latest revision (currently TIA-322-C, published June 2019). Do not rely on free PDFs labeled “ANSI TIA-322 PDF” from file-sharing sites—they often contain obsolete information or corrupted data.

ANSI/TIA-322, titled "Loading, Analysis, and Design of Antenna Supporting Structures and Antennas," provides the technical requirements for ensuring safety and structural integrity when installing or modifying communication towers. It works hand-in-hand with , which focuses on the construction practices themselves. Where to Find the PDF

Section 7 of the PDF specifies that for full-duplex Ethernet over multipoint cabling, the crosstalk between branches must be less than -35 dB at 100 MHz. For PoE (IEEE 802.3bt Type 4), the standard warns against using more than four taps per trunk due to voltage drop.
