Wireless router signal expanding reading the above mentioned solution is not more confused? Oh, I tell you my final solution now. I'm not going to pursue the number of antennas, transfusion rate and frequency emission. If you want to achieve at home, watching HD video, wireless, then the rate select 300M or more, can bridge between the router and the other is the same brand of wireless signal amplifier device. So no matter how much your walls, as long as a few router or bridge with two more wireless signal amplifier (repeater) is completely solved. Like I arranged router brands like Shanghai, three routers one in the study, one in the living room, a link to the dialer, three bridging them. So the whole house has a full grid signal. Finally, in the products is to choose some big brands, high prices on the wrong. Wireless LAN transmission principle and common wired networks, but also uses the ISO / RM seven layer network model router Shanghai Which is good, but at least two-layer model of the "physical layer" and "data link layer", the use of wireless transmission. Although various types of wireless network standards and norms are not uniform, but its transmission is certainly one way to look at the following two ways: the way radio waves and infrared mode. Infrared transmission which is currently the most widely used wireless network technology, is now frequently used in home appliances household appliances remote control almost all infrared transmission technology. As wireless LAN transmission, the biggest advantage is that infrared transmission without interference from radio waves, infrared and will not be used to limit the State Radio Regulatory Commission. V-Link router: the first one: the router interface can support species listed Shanghai router interface types, reflecting the versatility of the router. Common interface types are: Universal Serial Interface (via cable converts RS 232 DTE / DCE interface, V.35 DTE / DCE interface, X.21 DTE / DCE interface, RS 449 DTE / DCE interface and EIA530 DTE interface?? etc.), 10M Ethernet, Fast Ethernet interfaces, 10/100 adaptive Ethernet interfaces, Gigabit Ethernet interfaces, ATM interfaces (2M, 25M, 155M, 633M, etc.), POS interface (155M, 622M, etc.), Token Ring interface, FDDI interface, E1 / T1 interface, E3 / T3 interface, ISDN interface. Second: the number of slots available to users of the index refers to the number of slots in addition to the modular router CPU board, clock board and other necessary system board and / or system board dedicated slots outside users can use. According to the index, and user-board port densities can be calculated that the maximum number of ports supported by the router. Third: CPU in terms of the low-end routers or high-end routers, CPU is the heart of the router. Usually in the low-end routers, CPU is responsible for the exchange of routing information, routing table lookup and forwarding packets. In the router, CPU's ability to directly affect the throughput of the router (routing table lookup time), and routing computing power (influence network routing convergence time). Shanghai high-end routers router proxy packet forwarding and lookup table is usually done by the ASIC chip, CPU only achieve routing protocol, routing and distributed routing table calculation. The development of technology, the router a lot of work can be implemented in hardware (ASIC). CPU performance does not fully reflect the router performance. Router performance reflected by the router throughput, delay and routing computing power and other indicators. V-Link wireless router: Modular Router mainly refers to the type of router interface of the router and some extensions are based on the actual needs of the user to configure these routers at the factory generally only provide the most basic routing functions, users can the type of network you want to connect to select the appropriate module, different modules can provide different connectivity and management functions. For example, most modular router can allow the user to select the network interface type, some modular router provides VPN and other functional modules, some modular routers also provide firewall functionality, and so on. Most routers are modular router. Shanghai Which is good router, router Shanghai, Anhui Hefei, Anhui Technology provided by the Technology Development Co., Ltd.
