In today's world, Internet connectivity has become an essential task for every household and office. However, not everyone truly understands how devices like modems, routers, and access points function or where to strategically place a modem in an overall Internet network system.
This is not to mention the numerous tricks to learn when setting up a Wi-Fi network, such as placing the modem in an appropriate location—a topic often overlooked. In this article, Mytour will guide you in detail through the concepts of modem, router, access point, and modem router.
Distinguishing Between Access Point, Router, Modem, and Modem Router
* What is an Access Point, and what is its function?
Access Point functions as a central hub for transmitting and receiving wireless signals in a WLAN. In other words, an Access Point is similar to a Switch/Hub (network port splitter) but with the advantage of Wi-Fi capability, allowing the conversion from a wired network to a wireless one and broadcasting it to other devices on the same network. However, it's important to note that an Access Point only connects the wired and wireless networks and cannot assign IP addresses like a modem.
So, the primary task of an Access Point is to establish connections for all devices supporting wireless connectivity within a local network using a wired Local Area Network.
* What is a Router, and what is the function of a Wireless Router?
A Router facilitates the connection of wired networks to mobile devices through Wi-Fi functionality. However, its role extends to connecting with various local area networks (LANs).
You can think of it like this: if the only gateway into a house is the Internet connection, once inside, you have many choices to enter different rooms. These rooms are the various smaller networks divided from the Internet network. Of course, these smaller networks are only local area networks (LANs), meaning other users cannot access the LAN without passing through the main door (Internet gateway) to enter the house.
The Router's task is to connect all computers within the same local network linked to the Internet. The most noticeable feature of a Router is the WAN port, used to connect to the Internet through ADSL networks or by plugging in a cable from a modem.
The Internet server connects to the router through a modem, and the role of the router aligns with its name as a routing device responsible for directing network traffic between devices in the network.
Notably, a Router can assign IP addresses to devices within the LAN.
* What is a Modem, and what is the function of a Modem?
Modem (short for modulator and demodulator) is a device that modulates similar analog signals to encode digital data and demodulates carrier signals to decode digital signals. Internet users commonly use modem types, primarily coaxial cable modems and ADSL modems. Many modern ADSL modems use analog signal input through a line in connection.
After the digital signal reaches the user, the modem's task is to transform that digital signal into an Internet connection. Simply put, the modem is the gateway for the Internet to enter the house. Due to its significance, modems are often targeted by hackers and malicious individuals attempting to steal modem passwords. If you detect a stolen modem password, promptly reset the modem to restore the password and prevent unauthorized use.
* What is a Modem Router, and what is the function of a Modem Router?
Modem-Router: This is the most versatile device as it can both encode digital signals and perform functions like Wi-Fi broadcasting and data sharing within a local computer network. In general, a Modem Router combines the functionalities of both a modem and a router.
Among these devices, they are typically ranked by price from low to high as Access Point > Router > Modem > Modem-Router.
When to Use Access Point, Wireless Router, Modem, and Modem Router?
As the question is posed, when should you use Access Point, Wireless Router, Modem, and Modem Router? Firstly, it's crucial to understand the purpose of each device.
1. If you don't need internet but want to connect all devices in your home through a wireless network, then Access Point is the way to go.
2. If you want internet connectivity, the first essential step is to acquire a modem.
3. If you want a device that can multitask to save you the hassle of searching for multiple internet connection devices, a Modem-Router is an excellent choice. However, this device, although versatile, may face limitations in installation due to being stationary and unable to be placed and moved anywhere in the house or office.
4. If you simply want to extend the coverage and improve wireless connectivity quality throughout your entire home, then consider purchasing either an Access Point or a Router.
Almost all devices in this article are Wi-Fi-enabled, emphasizing the need to prioritize security. By regularly changing your Wi-Fi password, you can ensure protection against potential theft or unauthorized usage. Another method is to hide your Wi-Fi to avoid detection by numerous devices, preventing potential intruders from attempting to steal your password and limiting bandwidth usage.
Related to network systems, there is a wide variety of network standards worldwide, with CDMA and GSM being the two most popular communication standards in the United States. So, what are the differences between CDMA and GSM? Many people may still be unsure, and if you're interested, you can refer to our comparison article on CDMA vs. GSM differences that we've provided.
We hope the article has provided you with valuable insights.
