Wireless networks have become an essential part of our lives. From smartphones to laptops, we rely heavily on these networks to stay connected and access the internet. However, have you ever wondered which spectrums are used by wireless networks? In this article, we will explore this topic in detail and shed light on the different spectrums used by wireless networks.
To begin with, wireless networks use a range of different spectrums to transmit data. These spectrums can be broadly classified into two categories: licensed and unlicensed. Licensed spectrums are those that have been allocated by regulatory bodies to a particular organization or service provider. On the other hand, unlicensed spectrums are those that are available for anyone to use without any need for a license. In the following paragraphs, we will delve into the details of these spectrums and understand how they are used by wireless networks.
Wireless networks use radio waves, infrared, microwave, and millimeter wave spectrums. Radio waves are the most commonly used spectrum, as they are the least expensive to produce and have the longest range. Infrared is used mainly for short-range communication and is not suitable for large distances. Microwave and millimeter wave spectrums are used for high-speed communication and require line-of-sight.
Which of the Following Spectrums are Used by Wireless Networks?
Wireless networks are an important part of our daily lives, providing us with the internet access we need for work, play, and communication. But what type of spectrum is used by these networks? In this article, we will explore the various spectrums used by wireless networks in order to understand how they work.
Radio Frequency Spectrum
The radio frequency spectrum is the most common type of spectrum used by wireless networks. It covers a wide range of frequencies, ranging from very low (ELF) to very high (microwave). Radio frequencies are used to transmit data and voice signals, and are often the backbone of most wireless networks. The main advantage of using radio frequency is that it can cover large distances with relatively low power. However, it can be susceptible to interference from other devices and is also limited in terms of bandwidth.
Radio frequency is divided into various bands, such as 2.4GHz, 5GHz, and 60GHz. The 2.4GHz and 5GHz bands are the most commonly used for wireless networks, as they provide good coverage and are less prone to interference. The 60GHz band is usually reserved for wireless routers and is not suitable for large networks.
Infrared Spectrum
The infrared spectrum is another type of spectrum used by wireless networks. It uses light waves to transmit data, and is often used for short-range applications such as connecting two devices in the same room. The main advantage of using infrared is that it is very secure, as the signal can only be seen by the device it is intended for. However, it is limited in terms of range and is only suitable for small networks.
Infrared is divided into several bands, including 850nm, 940nm, and 1060nm. The 850nm band is the most commonly used for wireless networks, as it provides good coverage and is less prone to interference. The 940nm and 1060nm bands are usually reserved for short-range applications, such as connecting two devices in the same room.
UWB Spectrum
Ultra-wideband (UWB) is a type of spectrum used by some wireless networks. It uses extremely short pulses of radio waves to transmit data, and is often used for high-speed applications such as streaming video. The main advantage of using UWB is that it can cover large distances with relatively low power. However, it can be susceptible to interference from other devices and is limited in terms of bandwidth.
UWB is divided into several bands, including 2.4GHz, 5GHz, and 60GHz. The 2.4GHz and 5GHz bands are the most commonly used for wireless networks, as they provide good coverage and are less prone to interference. The 60GHz band is usually reserved for wireless routers and is not suitable for large networks.
Visible Light Spectrum
The visible light spectrum is a type of spectrum used by some wireless networks. It uses light waves to transmit data, and is often used for short-range applications such as connecting two devices in the same room. The main advantage of using visible light is that it is very secure, as the signal can only be seen by the device it is intended for. However, it is limited in terms of range and is only suitable for small networks.
Visible light is divided into several bands, including 850nm, 940nm, and 1060nm. The 850nm band is the most commonly used for wireless networks, as it provides good coverage and is less prone to interference. The 940nm and 1060nm bands are usually reserved for short-range applications, such as connecting two devices in the same room.
Microwave Spectrum
The microwave spectrum is another type of spectrum used by some wireless networks. It uses very high frequencies to transmit data, and is often used for high-speed applications such as streaming video. The main advantage of using microwaves is that it can cover large distances with relatively low power. However, it can be susceptible to interference from other devices and is limited in terms of bandwidth.
Microwaves are divided into several bands, including 2.4GHz, 5GHz, and 60GHz. The 2.4GHz and 5GHz bands are the most commonly used for wireless networks, as they provide good coverage and are less prone to interference. The 60GHz band is usually reserved for wireless routers and is not suitable for large networks.
Laser Spectrum
The laser spectrum is another type of spectrum used by some wireless networks. It uses light waves to transmit data, and is often used for short-range applications such as connecting two devices in the same room. The main advantage of using lasers is that it is very secure, as the signal can only be seen by the device it is intended for.
