A wireless communication network can be defined as a network in which the devices are connected by wireless means. A wireless network is a system that transmits data over radio waves. Wireless local area networks, wireless metropolitan area networks, wireless personal area networks, and wireless wide area networks are the four types of wireless networks, each with its own function. Depending on the use case, you might need to use a particular type. Then, you can select the appropriate technology for your situation. You can then choose the best method for your needs.
Mobile Phone Technology:
The most common wireless communication network is mobile phone technology. This technology has transformed our world like no other technology. Today’s mobile phones are not just for making calls anymore. They have dozens of additional features and capabilities. The latest generation of mobile communication technology is called 5G. It is the successor to the widely adapted 4G technology and is aimed at future automobiles and Internet of Things applications. There are four main types of wireless networks.
Wireless Networking:
It allows people to communicate in places that are hard to wire. It can connect across buildings, streets, rivers, and more. It can also be used to share a network with a variety of devices. It can even be used to create space within homes. And, unlike physical network mediums, wireless networks do not require hard wiring. They do not require wires to operate. So, you can use wireless networks wherever you want.
Types of Wireless Communication Networks:
Besides Wi-Fi and Bluetooth, there are four other types of wireless communication networks. There are mobile phones, wireless routers, and WiFi. A WiFi connection is the most common one, which allows different devices to connect to each other without any wires. Another type, Bluetooth technology, allows easy connections between multiple devices. Mobile phones and laptops can even make use of the kind of connectivity named Wi-Fi hotspots which also can be categorized as a type of wireless communication network.
Working Process:
Wireless networks work without a hardwired connection. A computer called an access point serves as the interface between devices and the network. Then, wireless clients connect to these computers. The access point sends radio signals to other computers on the network. In addition, attenuation refers to the signal’s strength and distance. However, the difference between a wireless connection and a wired one lies in the type of signal.
Components of a Wireless Network:
A wireless network can have many different types of components. For example, there are base stations and access points. These are the computer components that transmit radio frequencies to wireless-enabled devices. The access point also serves as an interface for other computers on the network. The access point receives data from other computers and communicates with them. Basically, there are other types of wireless communication networks; communications systems, personal computers, and public infrastructures. Among the categories, cellular is the most popular.
WLAN:
A wide area network, or WLAN, may be defined as an internet network. In a wide area, wires carry most of the data, and it is much faster and less susceptible to interference than cellular networks. Modern mobile devices and smartphones are typically connected to the internet wirelessly. This type of wireless network differs from WiFi in that it is not limited to a single location.
WiFi Networking:
The most basic form of a wireless network is a WiFi network. This is a type of wireless network that uses WiFi or a wireless access point. The WiFi and cellular network categories are similar in that they use a wireless connection to communicate. But in a cellular network, both types of networks are connected. The WiFi and cellular networks are similar in that they use different technologies to provide the service.
What Does it Mean to Communicate Via a Wireless Network?
Wireless communication is a way of sending data from one location to another without the use of wires, cables, or any other physical medium. Via general, information is conveyed from a transmitter to a receiver across a short distance in a communication system.
What Constitutes a Wireless Network’s Primary Components?
The following are the essential elements:
- Router that is wireless
- Wireless access points (WAP), or simply access point (AP)
- Client/wireless adaptors, also known as Network interface cards (NICs)
- Wireless repeater or bridge
- The controller is wireless
Which of the Five Types of Wireless Networks is There?
However, there are so many distinct types of wireless networks; LAN, WAN, PAN, and MAN along with many various standards like B, G, N, and AC. Determining which would work best for your purposes can be difficult.
The Different Types of Wireless Communication:
Wireless communication technology, in fact, has an unnoticed impact on all of our lives on a daily basis. If you own a company, you might be wondering how to get the most out of the numerous types of wireless communication.
1. Communication Through Satellite
Satellite communication is one of the most important types of wireless communication. Satellites allow individuals all over the world to communicate with one another. Because of the curvature of the planet, it may not be possible to send a signal to another country. One of the reasons satellites circles the earth is so that they may communicate signals among themselves and eventually to a distant country. All of this happens at breakneck speed. This technique is frequently used by NASA and other space agencies. Of course, launching a satellite into orbit is not inexpensive. As a result, extensive testing of the technologies involved is required prior to launch.
2. Infrared Communication
It is a type of communication that uses infrared light. Most houses have infrared communication in the form of a television remote control. How does it work, though? Infrared (IR) is a kind of information transmission that uses light that is invisible to the naked eye. This indicates that it is located between microwaves and visible light on the electromagnetic spectrum. To receive the light beam, infrared communication requires a transmitter and a photoreceiver. Because any disruption to the light will prevent the picture receiver from receiving it, IR can only work when there is a clear line of sight. That is to say, if you stand between the transmitter and the receiver, it is unlikely that it will operate.
3. Broadcast Radio
Broadcast radio, the most well-known form of wireless transmission on our list, was possibly the earliest type of wireless communication. Radio transmitters give data to receiving antennae in the form of radio waves. Electromagnetic transmissions include radio waves. Waves can be conveyed across multiple frequencies, and signals are quite narrow. This is why your automobile radio may pick up signals from a variety of radio stations. Radio communication is used by a wide range of people. Radio stations broadcast both educational and entertaining programming. Ships can communicate with each other and with the shore via maritime radio channels. Radio amateurs can communicate and use radio communication for personal purposes.
4. Microwave Communication
Microwave technology is a widely utilized and effective mode of communication. There are two sorts of technologies in this category;
- Satellite Microwave Communication
This is the most efficient way to send microwaves around the world. Microwave technologies, like infrared, require a clean line of sight. This means that if you wish to send a signal over a great distance, you should first send it up to a satellite. The only issue is that the signal to the satellite can be blocked by atmospherics in particularly dense gloomy weather.
- Terrestrial Microwave Communication
Microwave technology has the potential to be a very safe mode of communication. If a signal must be transmitted over a small distance, two antennae with a clear line of sight may be sufficient. After then, the signal can be sent between the two receivers. This eliminates the necessity for an external network connection.
5. Wi-Fi
Wi-Fi internet is a wireless electronic network with low power consumption. These can be found in nearly every shopping mall and cafe on the planet. A physical wired network is, in essence, connected to a router. As a result, a highly confined, the low-power wireless network is created. It is possible to join a variety of devices in the local network using this method. However, criminals and hackers have been known to target public wireless internet connections. As a result, it is critical that both users and providers implement password security defense measures when connecting to these networks.
6. Mobile Communication Systems
The rapidly growing mobile phone business uses technology similar to Wi-Fi but, on a much larger and safer scale. Customers are covered by mobile phone carriers on a national or even international basis. They accomplish this through a complicated combination of local networks and transmitters, as well as satellite support.
7. Bluetooth Technology
Bluetooth is a relatively young technology that is gaining in popularity. It’s just a straightforward means of transmitting data across a small distance. Messages or even files might be included in this information. Bluetooth technology was created to eliminate the need for physical cards. It does, however, have some drawbacks. It can reach a maximum distance of 30 feet. This can be reduced even more, but walls and other solid objects will not completely block it.
Wireless Communication Applications:
Security systems, television remote controls, Wi-Fi, cell phones, wireless power transfer, computer interface devices, and numerous wireless communication-based projects are examples of wireless communication applications.
Advantages:
Wireless communication systems have various advantages over wired systems. The following are some of the benefits of wireless communication.
Price:
Within wireless communication, the cost of fixing cables, wires, and other communications can be minimized. As a result, the system’s total cost can be lowered when compared to wired communication. Fixing a wired network within a structure, as well as digging up the earth to place cables and carry those wires across roadways, is a difficult, costly, and time-consuming process. Making holes in antique structures to fix the cables is not a smart idea because it compromises the structure’s integrity as well as its historical significance. Furthermore, in older buildings with no dedicated communication shape, Wi-Fi is the only alternative; otherwise, WLAN is the only option.
- Mobility
As previously said, the main advantage of this communication technology is mobility. It allows you to move about while still connected to the system.
- Simple Installation
Because we don’t have to worry about the irritation of cables, the system, and installation of equipment in wireless communication networks and communications is relatively simple. Furthermore, when compared to a comprehensive cable-based network, the time required to join a wireless system is far less.
- Consistency
Because there are no wires or cables involved in wireless communication, communication failure is not caused by damage to these cables, which could be caused by environmental conditions, a normal decrease of metallic conductors, or cable splicing.
- Tragedy Recovery
When fires, natural disasters, or floods strike, the system’s communication might be severely disrupted. Any data or information can be sent quickly and efficiently. These networks have lower maintenance and installation costs. The internet can be accessed wirelessly from any location. It is extremely beneficial for employees and doctors who work in rural places since it allows them to communicate with medical centers.
Disadvantages:
When compared to wired connections, wireless communication has some disadvantages. Wireless communication has a number of drawbacks, including health, security, and interference.
1. Interference
Signals can be transferred utilizing open space as the medium in a wireless communication system. As a result, there’s a potential that radio signals from one network could be interfaced with radio signals from other networks like Bluetooth and WLAN. When these technologies are operational, they communicate using the 2.4GHz band, and there is a risk of infiltration.
- Safety
The key worry in the wireless communication system is security because when signals are sent in open space, there is a danger that they will be interrupted and important data copied.
- Health Concerns
Continuous exposure to any type of radiation can be harmful to one’s health. Although the exact spectrum of RF energy that can cause injury is unknown, it is advised to stay as far away from RF radiation as possible. The wireless signals that go through the air can simply be captured by an unauthorized individual. It is critical to safeguard the wireless network so that illegal users cannot access the information.
Conclusion
Wireless communications have enabled billions of people to connect to the Internet, allowing them to profit from today’s digital economy. Similarly, agreed-upon mobile phone standards enable consumers to use their phones everywhere in the world. Furthermore, because the wireless network does not require any cables or wires, communication can take place even if the user is traveling. Wireless networks are less expensive to set up and operate, and data can be transferred at a faster and higher rate. It also requires less maintenance and has a cheaper installation cost. Aside from that, the wireless network may be accessed from anywhere at any time, which makes it more efficient.
