Different Types of wireless Communication Technologies
Any busy business owner should be pardoned for occasionally being confused between 5GHz WiFi and cellular 5G due to the variety of wireless communication protocols and types available on the market. We have put together an overview of the many, most frequently encountered types of Wireless Communication technologies and the types of wireless communication they are used.
Wireless Communication Types
In the year 2020, the term “wireless” will no longer be used to describe your grandmother’s antique radio. Today, there are more forms of wireless communication available than we ever imagined feasible even just 20 years ago, and quite a few of them go by the informal moniker “wireless.”
However, not all wireless technologies are created equal, and not all may be employed in the same applications. You may already be familiar with some of these terms: Examples of “wireless” include radio and television transmission, radar, cellular communication, global positioning systems (GPS), WiFi, Bluetooth, and radio frequency identification, all of which have drastically different applications in various circumstances. We’ll concentrate on the types of Wireless Communication technologies used most frequently in information technology nowadays.
Wireless Network Types
The two types of wireless networks that are most frequently encountered in real-world situations are:
Local Area Network (LAN)
Local Area Network (LAN), such as your office’s internal network or your home’s network of devices (computers, game consoles, mobile phones, and tablets connected to the same router in one location form a local area network).
In the past, establishing a local area network required a wired connection using what is known as an “ethernet cable.” WiFi is currently widely utilized for local networking, even if wired networks are still extremely popular for a variety of factors, including superior protection from interference and security when compared to wireless.
Wide Area Network(WAN)
The Internet could be seen as a wide area network (WAN), a sort of network that spans a greater area. Because they are typically faster, more dependable, and less prone to interference, wires are utilized to move the majority of the data moving through the network in the case of the Internet.
However, more and more people are using cellular data to access the Internet wirelessly since the introduction of the contemporary smartphone and other portable devices like tablets. Although it differs from WiFi, many less tech-savvy people are nonetheless perplexed by this.
Local Area Networks-Specific Wireless Network Types
Without the pervasive WiFi, it is difficult to fathom modern living. Since its inception in Australia as a radio astronomy experiment at Macquarie University, WiFi has come a long way. Today, around five billion devices use WiFi for networking, and that figure is rapidly increasing.
When cabling may not be feasible or if device mobility is a concern (for laptop and smartphone users), WiFi is frequently utilized to create local area networks. An office or residential property can typically be covered by the small- to medium-sized WiFi routers prevalent in everyday settings; repeaters can be used to enhance the WiFi signal’s range. In Australia, two radio bands are frequently utilized for WiFi connection.
When we discuss local area wireless networks, we are often referring to a situation in which a WiFi-enabled device, such as a smartphone, tablet, personal computer, or laptop, connects to a router in a business or home to offer internet access without the need for on-premises network cables.
Longer coverage distances are offered by the 2.4GHz (gigahertz) band, albeit at the tradeoff of slower data transfer rates (in simple terms, it is slower). It works with a variety of WiFi-capable devices.
In comparison to the 2.4GHz frequency, the 5GHz spectrum is faster and experiences less interference from common household appliances. However, because higher-frequency radios have less wall penetration, it does so at the expense of a smaller coverage area.
Some older devices might not be capable of operating at 5GHz and won’t be able to connect to 5GHz WiFi. It’s critical to keep in mind that 5GHz WiFi shouldn’t be confused with cellular 5G, which is an entirely distinct technology. Some router manufacturers further complicate matters by including “5G” in the names of their 5GHz WiFi networks by default on many routers. While “5G” refers to the fifth generation of cellular networks, 5GHz WiFi is a short-range, in-home, and office networking solution.
Wireless Network Types for Cellular Communications
When we discuss cellular wireless communication, we typically mean a situation in which a mobile phone, a smartphone, a tablet with a SIM card, or a laptop computer links to a cellular tower to enable internet access while on the road. For the transmission of voice and data, cellular communication normally makes use of radio waves with a specified frequency.
The third generation of wireless mobile communications technology is referred to as 3G. It is most frequently seen in cell phones, smartphones, and tablets with SIM card slots.
The fourth generation of cellular telecommunications technologies, or 4G, is referred to informally. It is up to ten times quicker than 3G.
Long Term Evolution, sometimes known as LTE, is an evolution of 3G rather than 4G, while occasionally being promoted as 4G LTE. However, in most common situations when coverage is not an issue, the performance of 4G and LTE is comparable, making it difficult for most users to tell the difference between the two technologies.
The fifth-generation (5G) cellular networking technology standard offers increased bandwidth (speed) compared to earlier cellular wireless network iterations.
Short-range Wireless Communication Devices
Short-range Wireless Communication devices use different types of wireless communication.
Not all wireless communication methods support networking or provide access to the internet (though some of them do allow for very short-range networking and file exchanges).
Radio waves in the 2.402 to 2.480GHz band are used by Bluetooth (and this must not be confused with the 2.4GHz WiFi we described earlier). Connecting wireless computer peripherals (including mouse, keyboards, speakers, and gaming controllers) and remote controls are among the typical everyday uses of Bluetooth (for example between a mobile phone and Bluetooth-enabled car or home audio systems).
Instead of using radio waves, infrared communication uses invisible to the human eye infrared light. Only short-range communication is possible with it, and both devices must be in the line of sight for it to work (because light does not readily penetrate solid objects such as walls, unlike radio waves).
We hope that by defining and describing the various wireless communication protocols utilized in IT applications, we have at least somewhat cleared up any misconceptions.
