【正文】 and so on. User interface(UI) determines the easy degree of operation, and then bring about the system’s final use recognition . To the HOMENET interface, its application environment and special use objects decide the following features[3]: Usability: the users of home work are various people, the age’s disparity from young to old, the culture level and relative technology is different from each other, so the usability of HomeNet is very important to develop the home work market, thus the UI must provide a flexible, simple and intuitional interface to the general user collective. Mobility: HomeNet is a heterogenous work, it consists of digital sub work, A/V sub work and control sub work. When all the electronics at home are connected by HOMENET, users should configure, control, manage and check the work performance and equipment status from different access points. Scalability: Due to the economics, technology and market elements, the process of HOMENET construction is not an instant procedure, but is a accumulating one, so the topology structure must facilitate the system upgrade and maintenance, and the UI should provide the proper interface to the new plugged equipment. Access section is the connection between inter and HomeNet, access technology can be divided into two types: wire and wireless ways, the wire way includes Modem, HFC/Cable Modem, FFTH and xDSL technologies, the wireless way includes WAP, LDMS and so on. Traditional Modem technology has low transmission rate, with the home work wide spreads, the access technology will transfer to Cable Modem and xDSL technology, and in the end, the FTTH and WAP technology will be the prefer shows the HOMENET logical architecture, the whole system consists of five layers: physical media layer, protocol layer, API layer, APP layer (application program) and UI (user interface) layer. The specifications of the underlying two layers has been distributed and used in 1 HomeNet architectureThe API layer is the key of HomeNet , the technologies of it is the hot issue of home networ. There are several munication media at home as following: TP (twisted pair), TL (telephone line), xDSL, Cable Modem, FB (fiber), PL (power line) and wireless trsmission (, HomeRF, Bluetooth) TP, TL and PL are current prevailing media in HomeNet, FB, xDSL, Cable Modem and wireless media will dominate in the future. The implement of connection scenarios are relative closely to the munication media . The two rules must be observed in HOMENET construction, the first is the usability and the another is the reasonable cost. Due to HOMENET’S various functions and each family’s affording ability, the connection scenarios will also be various. In the following sections, we discuss ether and fast ether work, home TL work, PL work and wireless work. Ether and fast ether work: ether work is often used in practic ,simplicity and reliability is its advantage, and the cost is lower than other scenarios. The patibility of it makes it convenient to upgrade from 10mpbs to 100mpbs and 1000mpbs ether work, and it benefits users from protecting the original investigates, so this is a preferred scenario in constructing HomeNet. TL HomeNet: Home TL technology makes it possible to build a high speed work at home by use already existing telephone lines. The 10mpbs TL specification has been distributed in HomePNA , a digital product can be easily linked to the work by a interface module which connects the telephone line plug and the product. Addition, the xDSL technology extends the PL munication band, and makes the TL HOMENET can afford the multimedia applications. PL work: this scenario interconnects the home digital devices by ubiquitous power lines, its biggest advantage is that most of the electronic products have been linked to PLs. Although the old PL work (X10) have difficulties to carry high speed data information, the new technology has implemented high speed data transmission. Wireless work: the advantages of it over wire work lie in flexibility, mobility and easy constructing. The technology maturity of the wireless work has been proved in the applications of restaurant munication and stock exchange information transmission, but the defect is its high cost in construction and the narrow munication band. With the appearing of new technologies, the wireless work will dominate the HomeNet market in the future due to its above tributes. The End There are still a lot things to do to spread the home work currently: first of all is the development of embodied OS and IC, then without the interoperable specifications the different devices can not municate each other directly, and the integration of HomeNet bees plicated due to much more protocols in the under lays, so much efforts should be taken to implement the dream of remote learning online,ordering online and so on through the HomeNet.
