A wireless network is a computer network that uses wireless data connections between network devices like laptops, smartphones, wireless headphones etc. Because “ceiling” cables do not require expensive cables, the most significant advantage is that they are usually simple, fast, and cheap to install.
In comparison, it is challenging to create a secure network if cables are placed on walls and ceilings to be expensive. But even if you have developed air conditioning, air communication can be a valuable way to expand or expand it. Of course, there is no such thing as air because most people will connect to the internet one day.
Basics of Wireless Networking
Wireless networks operate using radio frequency (RF) technology, usually in the form of radio waves. When radio waves are applied to an antenna, an electric field is created that can be diffused into the atmosphere.
Wireless networks come from devices called an access points (AP). The receiver is used to send wireless messages that the computer can detect and “manage.” Because wireless networks are usually wireless networks, access to devices is generally connected via a wireless network, such as an Internet connection.
Your computer must have a wireless network card to connect to the Internet and to connect to a wireless network. These batteries are immediately plugged into the computer, but if not installed, only if the laptop or notebook can plug air into the empty expansion slot, USB port or laptop, PC card slot.
1. Wireless LAN
Wireless (WLAN) technology allows you to access the Internet at home or in remote areas. Developed in the office and at home, WLAN technology is now used in stores and restaurants. The use of home networks has increased significantly as COVID-19 forces office workers, students, teachers, and others to work and study at home.
Most home networking services are simple. The modem is connected to a fiber optic cable/fiber optic cable from your service provider. The wireless service provider connects to the modem and receives the modem signal transmitted over the air by the 802.11 standards.
Corporate networks are complex. There is an access point (AP) on the roof, which delivers air to the surrounding area. Large offices require multiple access points, each connected to the back of the room via an Internet connection.
2. Wireless MAN
Regional airline networks have been developed around the world to provide access to domestic and other commercial networks. These networks cover a wider area than retail or residential networks, but the principles are the same. AP is near your home or phone in the coverage area. The Wireless Routher or AP connects to the Internet through a wireless network, and the wireless network is distributed locally. Users connect to the next AP, which expands the connection to the internet connection.
3. Wireless PAN
LAN wireless – up to 100 meters for most applications – uses commands such as Bluetooth and Zigbee. Bluetooth allows you to make wireless calls, connect your phone to your phone, or transfer lines between intelligent devices. Delivery is connected to the IoT network. Infrared technology has a few features, such as connecting remote objects to TVs and TVs.
Air carriers are constantly changing technologies and finding new ways to provide management services. These improvements result in higher data rates as well as higher aerodynamics.
4. Wireless WAN
Wireless WANs use mobile technology to access wireless or open networks. These networks allow users to call others using a wireless WAN or wireless network. Users can also connect to the Internet to access websites or applications based on servers.
Long halls are available almost everywhere in the United States and many other cities. The user connects to another Internet-connected cell or another Internet-connected tower.
Wireless Technology Standards
Since mobile communication has many technical principles, it is best to do your homework before purchasing the equipment. The most important principles of ventilation are the following:
802.11b: The first wireless communications technology, known as 802.11b (better known as Wi-Fi), first appeared almost a decade, but it still works.
802.11g: The 802.11g model was introduced in 2003 and offered high performance (i.e., speed and mass) and is still the most common wireless network technology today.
802.11n: Another standard update, 802.11n, is under construction and should be completed in 2009. Although the 802.11n standard is not yet complete, you can still purchase 802.11n products that can be updated later in the end.
All types of Wi-Fi (802.11b product, generation) use the same 2.4 GHz radio frequency, so they are compatible with each other, so you often use devices based on different standards in the same air conditioning. The problem is that access to the old device usually requires special settings, which can reduce overall performance. Of course, you want all wireless devices, access points, and computers to use the same technical standards and come from the same manufacturer if possible.
