Home network technologies

Aimed at the home LAN technology


1 Home PNA

As you can see, he stands in the Home Phoneline Network Alliance (PNA) is to build a network using a telephone line wiring is already in the house. Area using some of the phone line for voice signals to pass, because still has the disadvantage of staying at a slow speed of about 1Mbps. Simple level of network does not become a problem, but is about the HomePNA specification 2.0 10Mbps transfer rate level raised. Daisy chain (daisy-chain) in the form of reduced wiring complexity is thin compared to the LAN cable connected to use the telephone line, so installation is much easier.
Expensive, but compared to the transfer rate limits and general LAN card very popular not do. Apartment complex, home networking, rather than a kind of high-speed communication, etc. ADSL B & A, primarily being used.
) Daisy-chain concentrated in the hub, rather than the star-bus topology and connection string as the complexity of the wiring in the form of much less.


2 Powerline network

Technology came from a similar problem with the phone line consciousness. Difference between a telephone line instead of using powerline najiman power outlet is not coming because there is much less difficulty of wiring. Competitive compared to ADSL, but fall in the home network is simple to build and information in consumer electronics, high-speed communications, from the simplicity of the network connection when power lines have many advantages. Dissemination of the telephone line is not made, the developing countries have a fairly large compared to other high-speed communication advantages. Home information appliances alone without any other connection cable outlet in the building of home networking is possible, especially strengths naesewoogo.


3 Bluetooth (Bluetooth)

'Blue-tooth' unusual name of this technology, is one of the leader of the next-generation network technology. 10M within devices that connect at speeds of up to 1Mbps Bluetooth technology that tie in to the PC and laptop, cell phone, PDA, portable devices such as wireless access technologies. It is comfortable and fast synchronization of data between the growing portable devices and data transmission so that you can aim. Off devices or RF to infrared, unlike commonly used until now because even if there are no obstacles between the communication is possible. As the Bluetooth SIG (Special Interest Group) of Ericsson, IBM, Intel, Nokia, Toshiba, and exhibitors only evident technology is the world standard length solid polished. , However, have impeded the commercialization of thing did not become as cheap as expected, the price of the module.


4 HomeRF

Bluetooth and a little different from the field, but rival in the wireless network technology. As the name implies, in the home network, using an infrared non-RF approach take hold of the targeted building. Plans yet somewhat slow 1-2Mbps of speed, but not only to the new standard in the class increase the transfer rate of 10Mbps. Between Bluetooth and WiFi camp, but struggled to find their place, the direction of the future, depending on whether to allow the FCC in the new price is expected to be decided.


5 802.11B / Wi-Fi

Currently basing most of the high-speed wireless network products in Wi-Fi. 11Mbps class this group evolved from existing 2Mbps standard naenoteun products are already being sold in the market. Screen in the most pragmatic camp in the surrounding wireless home networking for now ahead of the group. To configure the network through several companies product mix compatibility certification guarantee is provided.


6 IEEE1394 / HAVi (Home Audio Video Interoperability)

Somewhat different from those of several previous groups, but the field may also be referred to as, ultimately, is competing in the home networking. 400Mbps to faster transfer speeds and plug-and-play, hot plugging supported significantly ahead of Apple in the development of the current IEEE1394 bus. Until now mainly use digital camcorder and video editing devices, etc. have been to transfer multimedia data, seems to occupy a large proportion of excellent points, thanks in home networking. MS of 'Universal Plug and Play (UPnP)' and the line 'Jini', over the place of the standardized wage a fierce quarrel seems
