Wi-Fi Explained: Working, WiFi-6, Wi-Fi Applications

Wi-Fi or wireless fidelity is ingrained into our everyday lives. Let us take you on a journey of what it means, how does it work. Did you know that wireless fidelity has gone through several generations since its inception in 1999? In this post, we will look at what WiFi is all about, how it works, the many types of WiFi, the several generations that have been released, and how STL is revolutionizing the WiFi landscape.

What is WiFi?

WiFi is a colloquial term denoting wireless fidelity, not an abbreviation. It is a wireless local area network technology that uses radio waves to access or connect to a network. This may be used on a variety of devices such as computers, smartphones, televisions, video game consoles, and so on. Simply speaking, it provides a standard way to connect with wireless networking. The WiFi network is based on 802.11 standards developed by IEEE. It is trademarked by the Wi-fi alliance and used as a brand name for products using IEEE 802.11 WiFi standards.

How does WiFi work?

Have you ever wondered how wireless gadgets communicate with one another? The simple answer is to use WiFi technology. Signals are transmitted to various devices via radio waves. The receiving device must be configured to receive waves of a specific frequency. The WiFi frequency range is 2.4Ghz and 5Ghz. This is a higher frequency than those used for walkie-talkies, mobile phones, TVs. This higher WiFi frequency range allows signals to carry more data.

Let us explain the process of how WiFi really works:

  • A chord, usually a fiber cable or analog line. This connects an internet source, like a broadband mode.
  • The WiFi router is the medium that receives the internet connection via a wide area network (WAN) port.
  • The WiFi router gives off wireless signals via radio waves to a card or an adapter in a computer, phone, or other devices to establish two-way communication.

Types of Wi-Fi Deployments

Typically, there are three types of wireless networking systems deployed. It is important to understand the suitability of each WiFi network for effective deployment:

Centralized Deployment – When there is a cluster of buildings and networks that are close to each other, a wireless network system is deployed centralized. Because the controllers are situated in a central area, this configuration consolidates wireless networks. Centralized deployment is commonly used on campuses because it is easier to upgrade and enable enhanced wireless functionality from a single location.

Converged Deployment – Using an access switch, this sort of deployment combines wired and wireless networks into a single device. The access switch serves as both a switch and a wireless controller, ensuring that users’ wired and wireless connections are consistent. This type of network system is typically used by businesses with branch offices.

Cloud-based Deployment – The cloud is used to manage network devices in this deployment. Dashboards are used to manage devices in various places. Due to the utilization of cloud services, all devices are visible to anybody with access to the dashboard.

The WiFi Service Management Platform, developed by STL, is a future-ready platform that includes Authentication, Billing, Captive Portal, Location-aware Services, Subscriber Analytics, Mobile App, and Integration with Mobile Core. The solution is incredibly user-friendly, and it enables new business models as well as a variety of ready-to-use use cases for smart cities and telecom carriers. These technologies have a significant presence among service providers and have been deployed in over 3500 WiFi networks in over 60 countries, including smart cities, hotels, airports, and other public WiFi hotspots.

Wi-Fi has expanded its reach to clients in all categories with extensible services and the most recent business models. This extraordinary increase in data consumption has yielded proven results, demonstrating a strong ability to provide continuous connectivity and a seamless experience, everywhere and at any time.

What is WiFi 6?

As technology refines itself, newer generations come into being. Wifi 6 is the newest standard in WiFi. The newest version of WiFi standards is 802.11ax (WiFi-6) and is an upgrade over the previous standard, which is 802.11ac (WiFi-5). This upgraded standard, Wifi 6, is mainly for compatible devices (like routers) to transmit wifi signals more efficiently. Wifi 6 was built in response to the growing number of devices in the world, and to improve performance in high network densities like apartments with multiple routers or outdoor stadiums. The term Wifi 6 was coined by WiFi Alliance as an industry designation and seen as a consumer-friendly name over its industry-standard name of 802.11ax.

WiFi-6 Explained!

Is Wi-Fi 6 really that fast?

WiFi 6 (802.11ax) is an upgraded standard over its previous version with better speed (upload and download) being one of the features. WiFi 6 can achieve a maximum throughput (download speed) of 9.6Gbps across multiple channels compared to 3.5 Gbps in WiFi-5.

The important thing to remember is that a single WiFi 6 laptop linked to a WiFi 6 router will only be somewhat faster than a single WiFi 5 laptop connected to a WiFi5 router. WiFi6 is all about upgrading the network as more devices connect to it. WiFi 6 often maintains robust connections even when several devices connect and seek data.

We can see how Intel has listed out WiFi 6 capabilities:

“Works 4 times better in dense environments, has a much higher data download speed (throughput), increases network efficiency 4 times over, has extended battery life.”

Difference between WiFi-6 and previous generations

A quick comparison of the different Wifi generations is given in the table below:

As we can gather, Wi-Fi 6 is an upgraded standard over the last one. The launch for Wi-Fi 6 which happened about 5 years after the last generation is mainly for:

  • Performance and reliability for streaming capabilities of a number of devices simultaneously.
  • Greater range of wifi signal. Devices used at the edge of the wifi range (more than 350 feet) will still have decent wifi connectivity because the network will send a stronger signal to those edge devices.
  • Wifi 6 automatically includes a new protocol called WPA3 which enables the network to be more secure. WPA3 is tough for hackers, as passwords are very secure and data is encrypted and rendered useless for them.
