These can be used to connect printer or desktop or mobile external hard disk drive to be used as a shared resource on the network. Some wireless routers have one or two USB ports. a three-stream wireless router allows transfers of up to 1.3 Gbit/s on the 5 GHz bands).
Some wireless routers provide multiple streams allowing multiples of data transfer rates (e.g. Wireless controllers support a part of the IEEE 802.11-standard family and many dual-band wireless routers have data transfer rates exceeding 300 Mbit/s (For 2.4 GHz band) and 450 Mbit/s (For 5 GHz band). Some dual-band wireless routers operate the 2.4 GHz and 5 GHz bands simultaneously. It also can be a distinct card connected over a MiniPCI or MiniPCIe interface. These are also integrated into the main SoC or may be separate chips on the printed circuit board. Īll wireless routers feature one or more wireless network interface controllers. Some routers implement link aggregation through which two or more ports may be used together improving throughput and redundancy. An Ethernet switch as described in IEEE 802.1Q may interconnect multiple ports. Wireless routers typically feature one or more network interface controllers supporting Fast Ethernet or Gigabit Ethernet ports integrated into the main system on a chip (SoC) around which the router is built. Depending on the manufacturer and model, it can function in a wired local area network, in a wireless-only LAN, or in a mixed wired and wireless network. It is used to provide access to the Internet or a private computer network. A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point.
