Basic Concepts of Wireless Network

Wireless networks or WLANs serve the same purpose as wireless networks connecting a computer.

Wireless networks or WLANs serve the same purpose as wireless networks connecting a computer. Since “air” does not require expensive wires, the biggest advantage is that they are usually easy, fast, and inexpensive to install.

In comparison, it is difficult to create a network by installing wires on the walls and ceiling of the office, so it can be expensive. But even if you have already developed air conditioning, air communication can be a valuable way to expand or expand it. Of course, there is no such thing as wireless because most people will connect to the internet one day.

Wireless Networking Basics:

Wireless networks operate using radio frequency (RF) technology, usually in the form of electronics connected to radio waves. When radio waves are applied to the antenna, an electric field is formed which can propagate into the atmosphere.

A wireless network is based on a device called an access point (AP). The main access point is to send wireless information that a computer can detect and “control”. Because a wireless network is often wireless, access is often connected to the device through a wireless network, such as an Internet connection.

To connect to a network and connect to a wireless network, your computer must have a wireless network card. These batteries are integrated directly into the computer, but if not, only if a computer or notebook can be ventilated with an adapter inserted into the empty expansion slot, USB port, or notebook., PC card slot.

1. Wireless LAN (Local Area Network) 

Wireless technology (WLAN) provides internet access in a home or remote area. WLAN technology, originally developed in offices and homes, is now being used in shops and restaurants. The use of home networks has increased dramatically as COVID-19 has forced office workers, students, teachers, and others to work and study at home.

Most home network services are simple. The modem is connected to a fiber /fiber optic cable from your local service provider. The wireless operator connects to the modem and receives the modem signal that is transmitted using the wireless system by standard 802.11.

Corporate networks are complex. An access point (AP) is placed on the ceiling, each carrying air to the surrounding area. Large offices require multiple access points, each connected to the back network of the company via a wired connection.

2. Wireless MAN(Metropolitan Area Network)

Wireless regional networks have been developed around the world to provide access to both domestic and non-commercial networks. These networks cover a wider area than a commercial or residential network, but the principles are the same. AP is near the house or phone, near the coverage area. The AP connects to the Internet via a wireless network, and the wireless network spreads widely throughout the region. Users connect to the nearest AP that spreads the link to their internet connection.

3. Wireless PAN(Personal Area Network)

Wireless LAN coverage – up to 100 meters for most applications – use commands such as Bluetooth and Zigbee. Bluetooth allows you to make hands-free calls, connect your phone to the phone, or transfer lines between smart devices. Delivery is connected to the IoT network. Infrared technology has a few features, such as connecting remote objects to TV and television.

Air carriers are constantly changing technologies and finding new ways to provide management services. These improvements lead to higher data rates and higher air technology.

4. Wireless WAN(Wide Area Network)

Wireless WANs use mobile technology to access wireless or open networks. These networks allow users to make other calls using a wireless WAN or a wireless network. Users can also connect to the Internet to access server-based websites or applications.

Tall buildings are available almost everywhere in the United States and many other cities. The user is connected to the nearest cell tower, which is connected to the Internet, or another tower that is connected to the Internet.

Wireless technology standards:

Since there are many technical principles for wireless networking, it is a good idea to do your homework before buying equipment. The most important principles for air technology are:

802.11b: The first wireless communication technology, known as 802.11b (better known as Wi-Fi), first appeared almost a decade ago, but it is still at work.

802.11g: A model called 802.11g was released in 2003 that offers high performance (i.e., speed and mass) and is still the most common wireless network technology today.

802.11n: Another upgrade standard, 802.11n, is currently underway and should be completed by 2009. Although the 802.11n standard has not been completed, you can still purchase products based on the 802.11n standard, which you can upgrade later. in the final act.

All types of Wi-Fi (802.11b products, generation) use the same frequency band 2.4 GHz radio, so they are compatible with each other, so you can usually use a device based on different standards within the same air conditioning. The problem is that a special configuration is often required to access the inheritance device, which in turn can reduce the overall network performance. Naturally, you want all your wireless devices, access points, and computers to be using the same technology standards and, if possible, from the same manufacturer.
