You are designing an interactive patient television system (IPTS) that will provide internet, nurse call and LCD television services. From the following, which medium will NOT support these services…

Balanced twisted pair is engineered for low-frequency voice and data signals used in horizontal cabling, not for transporting broadband RF-modulated television signals required by an IPTS backbone. An IPTS backbone must simultaneously carry internet data, nurse call signaling, and CATV/RF television, and twisted pair lacks the bandwidth and impedance characteristics to pass RF television signals. Coaxial or optical fiber media are required to carry all three services over a single backbone infrastructure.

Coaxial 1/2 inch hard-line cable is a broadband medium rated for RF signal transport and is commonly used in CATV backbone distribution supporting internet, nurse call, and television.

Multimode optical fiber supports high-bandwidth transmission of combined internet, video, and signaling services and is a valid IPTS backbone medium.

RG-11 coaxial cable is a large-diameter, low-loss broadband cable suitable for backbone-level distribution of CATV and internet signals.
