What is a Wireless or WiFi Router?
A wireless or WiFi router is a device that mainly does two things. One is to work like an actual router, that is to connect to internet. The second thing is to work as a wireless access point. The most common use of Wi-Fi routers is to connect to internet and provide wireless access point so that users can connect to internet wirelessly and enjoy location free internet (although you cannot connect beyond a certain radius). It can also be use to connect to a private computer network. The best thing of it is that it can function in a wired LAN (local area network), in a wireless-only LAN (WLAN), or in a mixed wired/wireless network, depending on the type of manufacturer and model you are using or planning to use.
Types Of Wi-Fi Routers
- Single Band
- Dual Band
- Single WAN
- Dual WAN
Single band router are those router which use 2.4GHz band (Only one band). These are based on 802.11b and 802.11g standards but some of “802.11n” routers use single band (2.4GHz).
Dual band router are those router which can operate on both 2.4GHz and 5.4GHz frequencies. 802.11n standard allow these wireless devices to use the dual frequencies. Wireless “n” dual-band routers are also available as “selectable” or “simultaneous” models, sometimes referred to as “single radio” or “two radio,” respectively. A selectable wireless “n” router, can operate in either 2.4GHz or 5GHz mode; a simultaneous “n” device can operate in both frequencies at the same time.
Single WAN and Dual WAN Wi-fi Routers
In simple language single WAN can help you connect to internet with just only one connection. That means it has only one WAN port.
A Dual WAN can help you connect to internet with two connection from same or different ISPs. That means it has two WAN ports. So, if one ISP is down you can connect with the other and you may not see any connection drop. Best for businesses that want 100% internet uptime.
