Why is telephony inside wiring (quad station) considered inadequate for modern communication?

Telephony inside wiring, particularly the older quad station wiring, is considered inadequate for modern communication primarily because it cannot support both data over telephone lines and digital voice communication effectively. Modern communication needs, including high-speed internet, voice-over-IP (VoIP), and streaming services, require substantial bandwidth and capabilities that quad station wiring simply does not possess.

Traditional telephony wiring was designed primarily for analog voice transmission, which had different requirements compared to the digital signals used today. With the advent of data-intensive applications and services, the older wiring has proven insufficient, as it cannot sustain the simultaneous transmission of voice and high-speed data that contemporary technological demands necessitate. Newer wiring standards, such as Category 5e or Category 6 cables, provide the necessary bandwidth and support for these essential modern communication functionalities.

While the other factors mentioned in the options may contribute to the inadequacy of telephony wiring, the inability to support the modern dual demands of data and voice communication is a core reason why it has fallen out of favor in the current landscape of telecommunications.
