Wireless Router: A router is a multi-port device that can connect different transmission rates up and running in a variety of LAN and WAN environments, you can use different protocols. Router belonging to the third layer of the OSI model - the network layer. Guidance data from one network to another network, but also to guide the transfer of data from one network to another network. First, the network interconnection: router supports a variety of LAN and WAN interfaces, mainly used for interconnecting LANs and WANs to achieve different communication networks to each other; and second, data processing: providing a packet filtering, packet forwarding, priority multiplexing , encryption, compression, and firewall functions; third, network management: router includes a router configuration management, performance management, fault management and traffic control. The so-called "routing" smart city refers to the transfer of data from one place to another place in the behavior and actions, and the router, it is the implementation of such acts operation of the machine, its English name is Router, it is a kind of connecting multiple networks or network equipment segment, it will be different networks or network segments of data information between a "translation" to enable them to each other to "read" each other's data, so as to constitute a larger network. A router is a connect multiple networks or network equipment segment, it will be different networks or network segments of data information between a "translation" to enable them to each other, "read" to understand each other's data, so as to constitute a more large networks. There are two typical router function, that is, data path functions and control functions. Data channel features include forwarding decision, forwarding, and output data link scheduling, etc., usually done by the hardware; control software to achieve general wisdom Which city is strong, including the exchange of information between adjacent routers, system configuration, system management. Ceiling wireless router (Wireless Router): wireless AP and the broadband router into one of the Expanded offering smart city channels, it not only has all the features such as simple wireless AP supports DHCP client, support for VPN, firewall, WEP encryption support etc., and also includes network address translation (NAT) functionality to support LAN users to share network connections. It can achieve a home wireless network Internet connection sharing, ADSL, Cable modem and residential broadband wireless sharing access. Wireless router can be directly connected to the Ethernet connection of all ADSL MODEM or CABLE MODEM, it can also be through the use of a switch / hub, broadband router and then access the LAN mode. Its built-in simple virtual dial-up software, you can store user names and passwords dial-up, may be implemented as ADSL dial-up access to the Internet, CM to provide automatic dialing features, without having to manually dial or occupier of a computer do the server. In addition, wireless routers typically also have relatively better security features. Mainly in the primary router 3G Router Wireless 3G embedded modules. First, use a tariff card user (USIM card) inserted 3G routers, dial-up networking via 3G network operators WCDMA, TD-SCDMA, etc., you can achieve data transmission, Internet and so on. WIFI router function sharing Internet access smart city parameters, as long as mobile phones, computers, psp with a wireless network card or with wifi function via 3G wireless router will be able to access Internet, wireless local area network to share 3G wireless network to provide a great convenience. Some manufacturers also comes with wired broadband access, 3G can not normally access the Internet. Through 3G wireless router, you can achieve a broadband connection, to meet or exceed the current ADSL network bandwidth, it becomes very widely used in the Internet and other applications.
