IT People Blog – Not many people understand about the meaning and benefits of wireless networks. Whereas in the world of telecommunications, computer engineering, and information technology, wireless networks have many benefits for very useful things. Usually, companies, both small and large, apply wireless networks such as wireless LAN/WLAN and Wi-Fi.
Definition of Wireless Network
As the name suggests, a wireless network is a network that functions without using cables as the transmission medium. Wireless networks usually connect a computer system with other systems using a variety of wireless transmission media. Examples are microwaves, radio waves, and infrared light.
For information, the wireless network itself began to be discovered and applied in 1970. This network was then used to communicate between areas that have a large area. Without a cable that connects each computer, of course all activities or information carried out using a wireless network will be very efficient in terms of cost and connection speed.
Wireless Network Topology
Along with the development of information technology, wireless networks have undergone several changes. Currently, there are at least two wireless network topologies, namely the infrastructure topology and the Ad-Hoc topology.
Topology Infrastructure on a wireless network is a type of network that uses a WLAN card for each computer used to communicate. In this topology, the access point is used as a medium to connect one computer to another using wireless.
In other words, every client or user who wants to use this network, then they must pass through an access point before being able to connect with other clients or users. The advantage of the infrastructure topology is that only people who can pass through the access point can connect. In a sense of wireless security this is quite good.
The second type of wireless network is the Ad-Hoc topology. Unlike the infrastructure topology, in this topology clients can connect with other clients without having to use an access point first.
The way the Ad-Hoc topology works is like how the peer to peer topology works. In other words, all clients can contact or connect with other clients that have been set up in the wireless network easily.
Benefits of Wireless Network
In a review of the meaning and benefits of wireless networks on this occasion, you certainly need to know about what are the advantages that you get when using a wireless network. At least there are some benefits that can be obtained. Are as follows:
• Improve Accuracy and Efficiency
As explained above that the existence of a wireless network will provide benefits in the form of efficiency in terms of cost and time. This is because wireless networks allow all connected client computers to communicate with each other.
This is one of the reasons why many large companies prefer to use wireless networks compared to LAN networks in general.
• Improve Reliability
The next understanding and benefit of wireless networks is to increase reliability. For that, you have to compare the use of a LAN network and a wireless network. On a LAN network, of course the longer the cable used to connect one client computer to another client will wear out or experience errors when used.
Not only that, computers that use LAN networks can also be disrupted by improper installation. Damage during installation will greatly interfere with the performance of computers connected via a LAN cable.
In contrast to wireless networks, they no longer need to pay attention to physical damage that may befall the cable or errors in the network installation. You only need to provide a network that can connect one client computer to another client computer.
With a network that does not rely on physical, the availability in the system can increase. In addition, users can also access data faster as long as the client computer is connected to a wireless network.
This is one of the reasons why wireless networks are more reliable than LAN card networks.

• Faster Information Exchange
Looking at some of the explanations above, it can be concluded that by using a wireless network, the exchange of information between one client computer and another client computer can take place more quickly.
Installation of a wireless network in an office or public location allows users to easily connect to the internet.
Disadvantages of Wireless Network
After learning about the meaning and benefits of wireless networks, you should also consider the disadvantages of this type of network. First, data transmission using a wireless network is between 1 Mbps to 2 Mbps only.
Second, the initial installation cost is quite expensive, although in the future, wireless network maintenance costs compared to LAN are cheaper. Third, data security is not guaranteed because if someone can break into the network, it is possible that all data can be hijacked. And finally, there is the possibility of a broken signal, especially if the three waves are unstable.
So a little review about the understanding and benefits of wireless networks, may be useful.
