Network implementation trade-offs in existing homes

Abstract

The ever-increasing demand for networking of high-bandwidth services in existing homes has resulted in several options for implementing an in-home network. Among the options are power-line communication techniques, wireless links, and glass single-mode optical fibers. Whereas it is easy to install high-bandwidth optical fibers during the construction of new living units, retrofitting of existing homes with networking capabilities requires some technology innovations. This paper addresses some trade-offs that need to be made on what transmission media can be retrofitted most effectively in existing homes.

Demonstration of an In-Building Optical Bus Network for Wireless Access

“…The RF front-end up-link amplifier gain (17), together with the gain of the in-line amplifier (2), compensate for the increase of NFUL with the number of cascaded optical links (14).…”

“…he next generation of in-building wireless access networks will require a significant increase of the capacity and a reduced power consumption for "Green" networking [1] and for extending the autonomy of battery-powered devices, with a limited overall electromagnetic radiation exposure for the user [2]. However, in nowadays in-building wireless local area networks (WLAN), severe radio propagation conditions leads to under optimum connexion data rates while wireless transmitters deliver maximum radio power authorized by telecommunication regulations, limiting the autonomy of battery powered devices.…”
