A wireless router is a hardware device used to connect a computer to a network without running cables from the computer to the router.

The router is the most important thing in today’s connectivity solution in a place. For connecting multiple devices wirelessly we need to depend on WiFi Router only.

What is Router?

A wireless router allows you to share an internet connection with several other computer/device users without having to pay internet subscription fees for each individual user. Users can quickly and easily connect to the internet, usually within several feet of the wireless signal.

Types of WiFi Router:

There are two types of wireless routers each of them designed for a different use.

  1. The first type allows you to connect computers within a single household as long as the computers are within the range of the router. This router type allows you to access the internet remotely.
  2. The second type of wireless router is designed for office application and covers a wider area. While wired routers cost less than wireless routers, wireless connections are convenient and becoming more reliable.

Brief History of Wi-Fi Routers:

  • First tinkered with by a professor at the University of Hawaii named Norman Abramson, the act of transmitting data over the air was first achieved via HAM radio in 1971, though the technology that made it work was pretty rudimentary by our standards today.
  • Due to the huge expense of the equipment that was required to make a HAM setup work, wireless technology and the routers that made it run would sit on the shelves until the mid-90’s when various formats and wireless frequencies were being proposed as the standard for the band that wireless internet would occupy.
  • By 1997, the IEEE (Institute of Electrical and Electronics Engineers) had agreed on the 802.11 standards, which at that time was tied to what we now know as 802.11b.
  • Since then, a few more leaps and bounds have been made in the space of wireless technology bandwidth and speeds. Each jump in the generation of tech would be, For example, the “b” standard was the very first to come out, and could support a transmission rate of around 11Mbps on the 2.4Ghz spectrum. Next came the “802.11a” standard in 2002, which was capable of transmitting upwards of 54Mbps over the newly minted 5Ghz frequency spectrum.
  • Fast forward to today, where the latest and hottest on the market is the 802.11ad standard, which is capable of transmitting a whopping 7Gbps over both the 2.4Ghz and 5Ghz spectrum at the same time.

How does a WiFi Router work?

Using radio waves transmitted over the 802.11 spectra, wireless routers take the binary signal provided by your ISP and send it through the air to a compatible receiving device. The router creates individual IP addresses for each new device that gets added to the network, and, in theory, at least, most home routers can support 250 number of connections at a time.

New routers take one internet signal and split it in a dozen directions or more, while also protecting users with a number of backend additions like parental controls and firewalls.

These features allow you to monitor and control the traffic that flows from the modem to the router and back again, acting as the bouncer/bodyguard that controls what kind of content and media your family can see at any given time.

Some other additions to the roster of router features include QoS management, media servers (through USB), MU-MIMO beam splitting, mesh networking, and a few select models even offer their own antivirus options in case you need every extra layer of protection you can get.

In short, the same way as a wireless cellular phone, a wireless router hooked up to a cable or DSL internet connection uses radio frequency waves instead of telephone lines to transmit and receive networking signals. This allows transmission of data from one location to another.

Data from the computer is translated into a radio signal and then transmitted. A wireless router receives the signal, decodes it, and then sends the information to the internet using a wired connection.

The router also can receive information from the internet, translate it into a radio signal, and then send it to the computer. An easy description is to compare a wireless network to a two-way radio communication. Radio and television programs are broadcast in a similar way.

There are some advantages of WiFi Router over wired networking:

  • Perfect for family use: Provides access to the internet for multiple users at home via multiple different devices as well as smartphones and smart devices
  • Easy to install: Getting set up with wireless internet is easy and straightforward. Most connections can be set up in about five minutes. Once up and running other devices can connect to your secure wireless connection once permission to join has been authorised. For security reasons, it is advisable to password protect your wireless broadband connection so that unauthorised users will not be able to access your connection.
  • No more wires: A wireless broadband connection will give you more freedom when it comes to being able to connect to the internet. No longer will you be limited to the restrictions that are bound by a wired connection. Also having fewer wires to deal with presents a simplified, hassle-free and tidier solution for accessing the internet in your home.
  • VoIP calls: Can be used to make VoIP (voice over Internet Protocol) calls.
  • Excellent combination with digital TV: Wireless connections are easier to operate in tandem with digital TV services.


WiFi Router is the most wonderful invention for wireless technology. Wireless routers are a constantly evolving set of devices, and the manufacturers who make them are always finding new and exciting ways to innovate on the 40-year old technology.

With 802.11AD routers just around the corner and fibre optic lines being laid everywhere, it won’t be long before these Wi-Fi workhorses will be pushing 4K streams of Netflix and Youtube to every device in your home at once, without breaking a sweat.
