Wireless network building wireless home entertainment platform Scheme

The home network infrastructure involves both hardware and software, at present, most developers do not design wireless network nodes in the house, so the equipment also needs their own layout, the main process is the wiring design of the bare house to the final software debugging, the author today to introduce how to build your home wireless network, Realize Wireless home theater.

First, hardware selection and networking

For a home wireless network is definitely a kind of fresh blood. How does the wireless network achieve the networking and sharing? In simple terms, the mainstream approach is to form a peer-to-peer network, from a home server to the ADSL (or cable cat) Another RL45 interface to connect the switch (cheap switch) in this way can be a bus-type network structure of the home network, bus structure to cope with the home LAN no problem, The advantage of bus structure is that the channel utilization is high, and the price is relatively cheap. The disadvantage is that only two network nodes can communicate with each other at the same time, and the network extension distance is limited. After installing the wireless network card driver in Windows, simply set up the wireless network with simple and easy to use.

The second method is to compose the star structure of the network, the advantage is the high channel utilization, at the same time can have more than one node to access each other without conflict. We can implement this structure at home through the wireless router.

Method one for small space Network is very practical, the second method is more suitable for the jump-layer pattern of housing use. So from the device to see the first way to build a switch (or wireless network card) can be, and the second form of construction, other need to connect the computer with a wireless network card, good to have a wireless router. As a whole, the second type of star structure costs higher.

The wireless local area network (WLAN) uses the radio wave as the transmission carrier, provides the wired local area network all functions, in the actual construction uses the hardware infrastructure does not need to bury, but directly in the building exterior wall or other empty place arranges the equipment. Wireless LAN is mainly composed of wireless hub and wireless network card and other devices.

You can use the wireless card extra

Wireless router in the transmission mode in line with 802.11b/g, in the actual use of the data from the cable cat will be through such equipment for other computers to access, in the previous few years, wireless routers to 802.11b as the standard, its instantaneous transmission rate of 8m/s, but because the current standard has been replaced, So the wireless router price is very cheap, For example, SMC 802.11B router (with four RL45 port) as long as 120 yuan, 802.11b with the current ADSL speed is absolutely no problem, now mainstream 802.11g product price in general around 300 yuan, the latest 802.11n router to thousand yuan, for the recent network of friends to choose 802.11g Products on it.
