Do I Need A Modem For Wifi

Clearing Up The Meaning Of Modem

nbn : Do I need a modem or a router?

The word modem is short for modulator/demodulator. It refers to a device used for dial-up internet, where data is sent over the same copper telephone lines that voice calls use.

The modem takes the ones and zeroes that represent the data packets sent over the internet and turns them into sound frequencies over copper wire. It also does the reverse, listening to the sounds coming from the internet and turning them back into binary code.

Modern modems used with DSL, fiber, cable, and mobile data are not modems in the terms original sense. However, what they do have in common is converting digital data from the computer into the format of the transmission systemfor example, converting electrical impulses into the light pulses used in fiber optics.

The most important thing that you should know is that a modem is a device that connects you to the greater internet. Its the transition point from your home LAN to the WAN .

How Do I Know If My Modem/router Supports 5g Vs 5ghz

If you have a dual-band Wi-Fi router, your router supports 5GHz technology. 5GHz is just another band of radio waves where you can get Wi-Fi signal. You can check in the product description of your router to see if it supports this technology as well.

If youre wondering whether your modem and router supports 5G technology that allows you to get wireless internet through a cell network, thats a different story. Your current Wi-Fi router doesnt support 5G technology unless you have coverage from a 5G home internet provider like Verizon, Starry, or T-Mobile. If you get service from one of these companies, theyll give you a router.

Help Modem vs. Router: How They

5G home internet is the most recent advancement in wireless data connection. Its technically a cellular network , but now home internet providers are tapping into it so as to power your web-connected devices at your house. Theyre able to do this through 5G-specific routers that use radio frequencies to pull the 5G signal from the cell towers in your area into your home. Then, a 5G broadband modem converts that 5G signal to Wi-Fi, spreading it throughout your home just like a traditional Wi-Fi signal from a traditional medium. Hence why 5G home internet is being called mobile broadband internet, as it can deliver a high-speed internet connection via the same networks that power your mobile phone plan.

How Does A Modem Work

You can classify the working of a modem device into two things. At first, it takes command from our devices as a digital signal and processes it into an analog signal that can be transferred via telephone or cable lines.

Converting digital signals into analog signals understandable by the systems servers is called modulation.

On the other hand, the modem receives signals from the servers of internet providers as analog signals.

At this stage, it converts these analog signals into a digital format so that your computer can understand the data sent by those servers. Converting analog signals to digital form is demodulation.

As the modem is involved in the modulation and demodulation of data signals, it gets its name mo-dem.

A router is focused on local area networking. It performs the following functions for devices in a home network:

  • Manages and assigns IP addresses.
  • Acts as the local domain name service.
  • Sends requests, such as for a web page, over the internet on behalf of your devices and returns the results.
  • Blocks incoming requests from the internet. More advanced routers let select requests through.
  • Connects several wired devices, as most standalone routers only offer one Ethernet port.

Whats the Difference Between a Modem and a Router?

If you wish to use WiFi or connect numerous devices, you’ll need both a modem and a router. You can only connect one computer at a time because most modems only have one LAN Ethernet connector, but a modem won’t provide the same level of protection as a router. If you have multiple devices that need to connect to the Internet, you’ll need a router. However, a router by itself will not allow you to connect to the Internet. A router must be connected to the modem to distribute the internet connection to your devices. Some devices combine the tasks of a modem and a router these days. As a result, you won’t need to purchase a separate modem and router while setting up your home internet connection.

What Is The Use Of A Modem

The internet has become a necessity these days that has transformed how things were done in the past. This era of quarantine, with people working, shopping, studying, and trading from home, has further increased the need for a stable internet connection.

However, not many people know about the significance of a modem for stable connectivity.

A modem is a device that enables the internet connection of devices at your home. Without a proper modem, sending and receiving the data signal from our computer devices to the outside world is nearly impossible.

Using a modem makes it possible for users to translate the electrical signal to digital ones because all modern devices understand digital signals.

Knowing the modem and its defining attributes will further enhance your understanding of the significance and use of modems.

Can You Just Use A Router Without Modem

Do You Need A Wi-Fi 6 Router?

You can conveniently use a router without using a modem. It can assign IP Addresses to connected devices besides transferring data among these devices.

On the contrary, you do not need a separate router if you are a single user of an internet connection at home. However, you will undoubtedly require a router if multiple devices in a house need web access from a single internet connection.

The router assigns IP addresses to every device on the network and helps in seamless connectivity. Another significant aspect of using a router is enhanced Wi-Fi coverage that is suitable for flawless connectivity if you live in a big house.

The answer to this question might seem incomprehensible if you do not know what the router is and how it facilitates the internet connectivity of multiple devices.

How A Cable Modem Works

Heres a short list of what happens after your providers signal enters your home:

Step 1: The modems tuner receives your internet providers modulated analog signal from the coaxial cable and moves it to the demodulator.

Step 2: The demodulator separates the digital wave from the carrier wave using quadrature amplitude modulation .

Step 3: The demodulator sends the digital wave to the analog-to-digital converter .

Step 4: The ADC reverts the digital wave into a bitstream.

Step 5: The error correction module checks that the conversion is correct.

Step 6: The media access control and processor separate the bitstream from digital TV data, if needed.

Step 7: The modems PHY transceiver uses Manchester encoding to convert the bitstream into electrical pulses.

Step 8: The modem transmits these pulses over an Ethernet cable by applying specific voltages to the copper wires.

When you reverse the steps, the modem eventually modulates the carrier wave using your data wave and delivers them to your providers CMTS. In turn, the CMTS demodulates and routes your data to the fiber-based internet. Fiber uses LED and laser pulses to send data, not carrier waves.

Theyre Designed To Run Continuously

The engineers who create internet routers design them to run 24/7 so they can always be available to provide you with internet access whenever you need it. As such, some routers dont even have power switchesyoud need to unplug them to shut them down.

One major advantage of leaving a router plugged in continuously is that its always ready for action. As soon as you unplug a router, then power it back on, the device will go through a boot-up process that might include negotiating a new dynamic IP address from your ISP. The process could take several minutes before your internet access is ready to use again.

Furthermore, while there isnt a broad consensus about this, some people think that powering an electronic device up and down repeatedly can potentially shorten its lifespan. It puts stress on its internal components with the changes in current and temperatures involved. So if you want to increase the chances of your router or modem lasting longer, leave them turned on all the timeas long as theyre in use. If you dont use them for a long time , turn them off.
