We look at home networking from a service-oriented point of view

We first identify the services required in each room of a home and then determine the ultimate end-equipment needed

We envision that future homes will be very simple without many “electronic boxes” as of today

The focus of future home networking will be on the distribution of needed services to the ultimate end-equipment via a simple, yet smart, flexible and reliable, home network

Currently, each service listed in Table 2 is accomplished by an “electronic box”, e.g., DVD players, VCR, radio etc. Some of these electronic boxes have duplicate functionalities

In the near future, with the immersion of all-digital media, the end-equipment will be very simple

Compared to homes nowadays, future homes will be very simplistic and only carry essential end-equipment such as universal displays, speakers, microphones and/or some additional input/output devices

23

24

That is simple and reliable, is to use a semi-decentralized architecture as shown in next page

The brain of the home network is the home media server. It not only stores all digital media information of the home but also provides access to external networks

These room-servers are connected together via an inter-room network and are synchronized with the home media server periodically

“Room services” in a particular room are provided by its corresponding “room-server”

25

26

Currently, there are different kinds of technologies available, e.g., coaxial cable, plastic optical fiber (pof:100/1000Mbps), power line, phone line, and wireless (IR and RF)

The selection of medium depends highly on whether it is intra-room or inter-room connection

27

For inter-room connection between “room-servers”, one may have to drill holes and snake cables/fiber through walls

Current best wireless solution is IEEE 802.11a/b/g which provides up to 54Mbps

However, with the upcoming high-throughput IEEE 802.11n WLAN standard, wireless connection of more than 100Mbps at 30m is feasible

For intra-room connection, one can use cable and/or pof in order to provide reliable and high bandwidth services.

Fortunately, with the advancement in wireless technologies, we can provide high-rate wireless intra-room connections using the upcoming IEEE 802.15.3a ultra-wideband (UWB) solution which can provide 110Mbps at 10m or 480Mbps at 4m.
