Which of the Following Wireless Communication Technologies Can Be Described By Their Characteristics?

 These technologies are used in various situations and have different characteristics. One of the main differences between them is the range they can cover. The farther a signal can travel, the more powerful it is. But it’s important to note that these technologies must be used at both ends of the connection to ensure the highest possible range and data rate.

Wireless networking is the process of connecting wireless devices. It is widely used in home networks, telecommunications networks, and business installations. This type of network is often associated with a transmission distance limitation. Some of these networks are a combination of different wireless communication technologies. Which one best suits your needs? Which of the following technologies can best describe its strengths? Its most common advantage is that it’s flexible and scalable.

Wireless local area network (WLAN) is a popular form of wireless networking. It allows users to access a local area network and the internet through a single connection. The speed of this technology is much faster than what is available with consumer Internet access. WLAN technology is replacing many of the older, less popular systems like DECT and HIPERLAN. These systems are mostly local and don’t support seamless network migration.

Wired and wireless networking are two different types of wireless networks. The first type is used to connect a large number of devices. The latter is often referred to as “wireless networking.” The last type uses an Ethernet cable to transmit data. This type of network can be viewed as a network of wireless devices. In addition to telecommunications networks, it’s also used for home and business installation.

What Are Some Few Tips to Secure Wireless Network?

Keep your wireless network safe by putting in place a set of policies and identifying who is responsible for them. When new hazards are found, review these policies on a regular basis to ensure security control.

Administrators can employ discovery tools to detect rogue access points and unauthorized peer-to-peer connections, as well as assess vulnerabilities. Strong passwords should be used to protect the administration interface of your wireless router or access point.

SSID (Service Set Identifier) is disabled – When you disable SSID, your network becomes invisible to your neighbors and passers-by. This will prevent illegal access to your network.

Secure your network with VPN – VPN allows employees to connect to the business private network in a secure wireless network environment. Data is encrypted and protected in this network from unauthorized access, including eavesdropping and man-in-the-middle assaults.

Personal firewalls should be used: Install your personal firewalls because wireless adapters open up additional attack vectors. Applying security and application patches to remedy certain security vulnerabilities is a good practice.

Reviewing the network on a regular basis: It’s a good idea to check your company’s wireless network for vulnerabilities on a frequent basis. This will assist you in identifying and resolving vulnerabilities before they are exploited by attackers on your wireless network.

What Are Some Types of Wireless Data Transmission?

Radio Frequency Transmission

In wireless communication, radiofrequency is a type of electromagnetic transmission. RF signals with frequencies ranging from 3kHz to 300GHz can be easily created. Because of their ability to pierce through objects and travel large distances, they are employed in wireless communication.

One sort of wireless data transmission is the radio system, which is a wireless medium that transmits data by transmitting low-frequency electromagnetic waves to distant locations via an electrical conductor and an antenna. With their strong amateur broadcasting equipment, ham radio enthusiasts share information and serve as emergency communication assistance during disasters, and can even send digital data over the radio spectrum. The wavelength, transmitter strength, receiver quality, antenna type, size, and height all affect radio communication.

Infared Transmission

Infrared radiations have longer wavelengths than visible light and are therefore more powerful. Typically, these are used for short-range communication.

Infrared is a data transmission technique that uses light-emitting diodes or lasers to send data signals. Infrared energy is electromagnetic energy with a wavelength longer than red light. In an infrared system, information cannot pass past obstructions, but it may be blocked by light. The point-to-point system, in which transmission is possible between two points separated by a range and line of sight, is one type of infrared.

In a point-to-point system, the signal frequency varies from 100 GHz to 1,000 terahertz (THz), with speeds ranging from 100 Kbps to 16 Mbps. The broadcast system is another technique of infrared communication.

Transmission of Microwaves

In wireless communication systems, microwaves are a type of electromagnetic transmission. Microwaves have wavelengths ranging from one meter to one millimeter. The frequency ranges between 300 MHz and 300 GHz. These are popular for long-distance communications since they are less expensive. Microwave is a sort of wireless data transmission that uses two different methods to deliver data. The satellite technique, which transmits information via a satellite orbiting 22,300 miles above the Earth, is one method for transmitting data using the wireless media of a microwave. Ground stations transmit and receive data signals to and from the satellite in frequencies ranging from 11 GHz to 14 GHz, with a transmission rate of 1 10 Mbps.

Cellular Phones

Generations are used to track the evolution of cellular networks. Cellular and cordless phones allow many distinct users to communicate across a single frequency band. Wireless devices such as cellular phones and cordless phones are two additional examples.

Although cordless phones have a limited range, mobile phones often have a considerably greater range than local wireless networks since they rely on big telecommunication towers for coverage. Similar to Global Positioning System (GPS) equipment, some phones use satellite signals to connect.

Adapters for Wireless Networks

Wireless adapters are hardware devices that enable wireless connectivity and are installed inside computers. A computer without a wireless adapter will be unable to connect to a router and thus access the Internet. Wireless adapters are incorporated into the motherboard of some computers, but stand-alone wireless adapters can also be installed to add wireless capability.

Repeater (Wireless)

A wireless repeater is a wireless networking device that extends a wireless router’s range. A repeater receives wireless signals, enhances their power, and then sends them out again. Placing a repeater between the router and the PC connected to the router can improve the signal’s strength.

What Is the Significance of Wireless Communication?

Efficiency in Terms of Cost

The utilization of connection wires is required for wired communication. Communication through wireless networks does not necessitate a complex physical infrastructure or routine maintenance. As a result, the cost is lowered.

For example, a company that provides wireless communication services does not incur a lot of expenses, thus it may offer low consumer rates.

Flexibility

People can communicate regardless of their location thanks to wireless communication. To send and receive messages, you do not need to be in an office or a telephone booth. Miners in the outback can use satellite phones to communicate with loved ones, improving their overall well-being by keeping them in touch with those who matter most to them.

Convenience

Wireless communication technologies, such as cellphones, are relatively simple to use and may thus be used by anyone, regardless of location. To receive or send messages, there is no need to physically connect anything. Wireless communications services, for example, can be found in Internet technologies like Wi-Fi. We can now connect with practically anyone, anywhere, at any time, because network connections are no longer a hindrance.

Speed

Improvements in speed can also be noted. The accuracy and speed of network connectivity and accessibility were greatly improved. A wireless remote, for example, can run a system faster than a cable one. If something goes wrong with a machine, wireless control can easily stop it from working, whereas direct control couldn’t.

Conclusion

Why do we need wireless communication when wired communication can perform most of the functions that wireless communication can? Mobility is the fundamental and most crucial benefit of wireless communication. Wireless communication, in addition to mobility, provides flexibility and convenience of use, making it increasingly popular day by day. Wireless communication, such as mobile telephone, can be done anywhere, at any time, and with very high throughput. Infrastructure is another crucial consideration. Infrastructure development and installation for wired communication systems is an expensive and time-consuming task.

The advancement of wireless technology has resulted in numerous breakthroughs due to its useful qualities. The transmission distance can range from a few meters (for example, the remote control on television) to thousands of kilometers (for example, radio communication). Cellular telephony, wireless internet access, wireless home networking, and other applications can all benefit from wireless communication.

Wireless communication eliminates the cost of establishing wires, cables, and other infrastructure, lowering the overall cost of the system when compared to wired communication. Installing a wired network in a building, digging into the ground to lay cables, and connecting those wires over streets is a complex, expensive, and time-consuming task.
