A Guide To Types Of Wireless Technologies

We cannot imagine a world without wireless technologies today. Wireless communications have made it possible for billions across the globe to log onto the Internet to access information. These communication technologies can be of various types and it is natural for one to get confused with them. There have been several attempts to integrate blockchain into wireless communications from a number of perspectives. Blockchain, as an innovative and revolutionary technology that has emerged in the last decade, offers a promising solution. Also, Blockchain technology is the greatest technology behind the most popular cryptocurrency Bitcoin. To learn more about Bitcoin and bitcoin trading, apps like Bitcoin Prime can help you exponentially. It is a trading bot that executes the bitcoin trading autonomously.

Earlier, the word “wireless” was used to mean the radio. But wireless indicates completely different things in 2021. However, at the same time, not all of these available wireless technologies are identical. Neither can these be used for the same types of applications. You are probably familiar with the more common ones like radio or TV broadcasting, cellular communication, GPS, Bluetooth, etc.

An Overview of the Types of Wireless Technologies:

LAN: Local Area Network refers to the most commonly-used wireless technology in offices. It can be a network comprising of your home devices like PCs, game consoles, and tablets that are linked to the same router, or an internal office network. Originally, wired cables called the Ethernet were used for installing LAN. Wired networks have not completely lost their relevance, especially because they have better security protection, but Wi-Fi is now the go-to solution for LANs.

WAN: Wide Area Network refers to network covering a larger area; the most common example is the Internet. Here, wires are installed for moving huge volumes of data around the glove as these are more reliable, quicker, and less prone to interferences. As more and more sophisticated gadgets make an entry like the smartphones or tablets, users have started to connect to the Internet through cellular data or wireless technology.

Types of Wireless Network for LANs:

Can you think of working or living today without access to a Wi-Fi connection? The Wi-Fi has come a long way since its origins in Australia. As of now, almost 5 billion devices are using this technology for networking. Wi-Fi is used for establishing LANs where moving devices or using cables can be impractical. So, you will find Wi-Fi routers covering small to medium-sized workspaces like a residence or office premise. Repeaters can be used for increasing the Wi-Fi coverage.

Besides the 2.4GHz band guarantees a long coverage range but at the cost of data transmission speed. So, this connection is likely to be slow compared to the 5GHz which is speedier, and lees prone to interference from regular household appliances. Outdated and older devices may not be able to use this technology and cannot therefore connect to a 5 GHz Wi-Fi. This is however not the same as the cellular 5G network.

For cellular wireless connectivity, needed for devices like smartphones or sim-card enabled laptops and tablets, there must be connection with a cellular tower in order to get web access on-the-go. Cellular communications will use radio waves of a certain frequency for voice and information transmission.

3G is the 3rd generation of wireless telecom technology mostly found in smartphones and sim card-enabled computers. 4G refers to 4th generation cellular communication technology that is much faster than 3G.LTE or Long Term Evolution is often called 4G LTE but is primarily an extension of the 3G. 5G refers to the 5th generation technology ion cellular networking which offers much higher bandwidth upgrades than the previous ones.

Besides these wireless technologies for long-range communication, there are some designed for short-range. Bluetooth, for instance, uses radio waves for connecting wireless peripherals like mouse, speakers, or keyboard. Infrared communications make use of invisible infrared light instead of radio waves and are used for short-range connection.
