Wireless router is very important for personal network living.
From technology, Wireless router is mainly classified in wireless wifi router, wireless wimax router, and wireless cell router. From used filed, wireless router is classified soho (also called in non-industrial) class, and industrial class for Industrial Ethernet Router. SOHO is for large data use, for example 3G router (including EVDO Router, HSDPA Router, and HSUPA Router, and HSPA Router.)
A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point and a network switch. They are commonly used to allow access to the Internet or a computer network without the need for a cabled connection. It can function in a wired LAN (local area network), a wireless only LAN (WLAN), or a mixed wired/wireless network. Most current wireless routers have the following characteristics:
1. LAN RJ45 ports, normally 1 or 2 or 4 ports, which function in the same manner as the ports of a network switch
2. A WAN port, normally 1 RJ45 port to connect to a wide area network, typically one with Internet access. External destinations are accessed using this port. If it is not used, many functions of the router will be bypassed.
3. Wireless antennae. These allow connections from other wireless devices (NICs (network interface cards), wireless repeaters, wireless access points, and wireless bridges, for example), usually using the Wi-Fi standard.
4. Some wireless routers also include a DSL or cable modem in addition to their other components.
As for the wireless antenna, contains GSM/3G cellular antenna and WiFi/Wimax antenna, with different connecting type, such as SMA. Normally antenna is default packed by manufacturer. High gain antenna is available for replacement to receive better and stronger signal so as to get good receiving and transmission of data.
