Wireless Networking: Introduction
In the past few decades, the planet has been becoming more mobile. The current global lifestyle is causing many problems and the traditional ways of networking are not sufficient. Their movement is severely restricted when users must be connected to a network by using physical cables. Wireless networking doesn’t have to be restricted and allows users to move freely. Wireless technologies are able to invade conventional “fixed” or wired networks. This move is evident to someone who travels frequently.
Wireless networking for voice telephone telephony has opened up a new market. The voice call market was impacted by the addition of mobile access to telephony. Callers could connect to people and not computers. We are currently witnessing an equally significant shift in the networking of computers.
This article will focus on the following:
- Wireless networking is defined.
- How wireless networks work.
- Types of wireless network.
- Wireless networking standards
- Wireless networking offers many benefits.
A quick look at networking
Computer network refers devices like computers, fax, or printers that are connected or linked together to exchange information and resources. It uses transmission media, such as cables and wires. Local Area Networks, or LAN, are small areas where computers can be connected to each other via communication cables.
What is wireless networking?
Wireless networks allow devices to stay connected to the network and roam free of cables. Access points amplify Wi-Fi signals so that a computer may be distant from a router, but still connected to the network. Connect to the wireless network of that organization by connecting to a WiFi hotspot at a cafe, or any other public location.
Only difference between wired and wireless networks is that wired networks use cables for connecting devices to the Internet. The downsides of a wired network are many, as opposed to wireless networks. The main disadvantage is that the router is tied to your PC. Most wired networks make use of cables connected to an Ethernet port on a router, and the other end to a computer.
Why go wireless?
It is possible to get a little too far ahead of the technology by digging into it. Wireless networks have significant advantages, no matter what protocol they use or what information they contain.
Mobility is the main benefit of wireless networking. Wireless network users have the ability to connect to existing networks to allow them to travel freely. Because the mobile phone is connected to the cell towers, it can connect users and allow them to travel far.
How wireless networks function
Wireless Local Area Networks (WLANs) serve the same purpose as wired ones to connect computers. The primary benefit of “wireless” is its lack of expensive wiring. It is often simpler, faster, and more affordable to set it up.
However, it can be expensive and labor-intensive to install a network using wires that are dragged over walls and ceilings in offices. However, a wireless network can be cost-effective for expanding or increasing your network even if it is already established.
Types and types of wireless networks
Now that you know how wireless networks work, let us focus on the different types of wireless.
Wireless Local Area Networks – WLAN
WLAN refers to a network that connects two or three computers through a wireless distribution channel. They are equipped with high-frequency radio waves, and an AP (access to the internet).
These devices are convenient because they enable users to move freely within the coverage area. They are also known locally as Local Area Wireless Network (LAWN).
Wireless Wide Area Networks (WWAN).
WWAN is also known by the term wireless broadband. It makes use of cell towers. This tower transmits radio signals over distances of thousands of miles. WLAN is only able to reach a few hundred feet. It includes three major technologies: Global System for Mobile communications, Code Division Multiple Access (CDMA), as well as the newer WiMAX.
These technologies are beyond this article’s scope, but you can look here for additional resources. One thing to keep in mind is that Wide Area Networks are not connected to your individual computer but to several local networks.
Wireless Metropolitan Area Networks (WMAN).
MWAN’s coverage area is approximately equal to that of a large city. It is smaller than WWAN but more extensive than WLAN. It belongs to one entity like the government, Internet Service Providers, and cooperation. MWAN blocks access to subscribers or authorized users only. WMAN can be represented by *WiMAX.
Wireless networking offers many benefits
It has greatly contributed to Voice over Internet (VoIP), as calls can now easily be made over this protocol.
It has enabled mobility which is an even greater benefit to its users. Servers can now be accessed anywhere Access Point access allows.
They are cheaper than wired networks that can cost a lot to buy cables.
Thanks to current technology and data encryption methods, the network can be protected. This allows sensitive information to be shared.
