Wireless Networking is a technology that is much older than what many people think.
In 1997, the IEEE agreed on the 802.11 standards.
The very first standard that came out was “b” that could support the transmission rate of up to 11Mbps on the 2.4GhZ spectrum.
Then in 2002, the 802.11a standard came which could transmit 54MBps over the 5Ghz frequency spectrum
What is a Wireless Router?
It is networking equipment that takes the internet signal from your ISP and then routers it using different antennas.
Using it you can also turn a Wi-Fi signal received into an Ethernet connection.

The difference between a modem and a wireless router is that the first one is used only to broadcast the signal which it received while the second one has the responsibility of decoding it first,
Modem is used for modulating and demodulating the signal.
A wireless router issued to connect to modem which then transmits the WiFi signal throughout your house so that you can quickly get connected to the internet wireless.
In this case, you need not connect your device directly to the modem.
Why Go Wireless?
The main reason is that portable devices use WiFi.
In this case, you don’t need to connect to the internet via cables.
Wireless Router Working:
It includes the functions of :
- Wireless access point
It converts the incoming broadband signal and then transmits it through your house.
Then the wireless-enabled devices pick up this signal.
The modern wireless router provides the following characteristics:
- One or multiple NICs that support fast Ethernet or Gigabit Ethernet which is integrated into the main SOC.
- One or multiple WNICs that support IEEE 802.11 standard family.
- They also contain an Ethernet switch that supports Gigabit Ethernet or the Fast Ethernet.
- Some of them also have either xDSL modem or the fiber optic modem.
- The dual-band wireless router can easily operate both the 2.4GHz and the 5GHz bands simultaneously.
- Some such routers also have USB ports. One USB port is meant to be designated for the printer while the second one is for desktop or the mobile external HDD.
Some Notable Manufacturers:
- Apple Inc
- HP Inc
Such embedded device has most commonly Linux OS.
Sometime VxWorks is also used.
A light web server software runs on the device that configures the device over a web UI.
Some Interesting Facts:
1) Using Multiple Routers:
Home network aren’t bound to use only one router.
The wireless network can get more benefit by adding a second router to boost the signal.
2) Some Routers Don’t allow Wireless Connection to Be Turned Off:
As we know that wireless support wired Ethernet connection too.
Therefore if a network uses the internet connection the Wi-Fi connection needs to be turned off for better performance.
Some routers don’t allow it to be turned off without turning off and powering down the whole unit.
This feature is sometimes omitted as it requires the some extra cost to support it.
There before buying a router do research about it carefully.Top
