A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network. 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.
Most current wireless routers have the following characteristics:
- Some wireless routers come with either xDSL modem, DOCSIS modem, LTE modem, or fiber optic modem integrated.
- IEEE 802.11ac compliant or ready.
- Some dual-band wireless routers operate the 2.4 GHz and 5 GHz bands simultaneously.
- 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 wireless routers provide multiple streams allowing multiples of data transfer rates (i.e. a three-stream wireless router allows transfers of up to 1.3 Gbps on the 5 GHz bands).
- Some wireless routers have one or two USB ports. For wireless routers having one USB port, it is designated for either printer or desktop/mobile external hard disk drive. For wireless routers having two USB ports, one is designated for the printer and the other one is designated for either desktop or mobile external hard disk drive.
- Some wireless routers have a USB port specifically designed for connecting mobile broadband modem, aside from connecting the wireless router to an Ethernet with xDSL or cable modem. So, can be inserted a mobile broadband USB adapter into the router to share the mobile broadband Internet connection through the wireless network.
