The use of WiFi as a means to connect to the Internet has become commonplace. It is now a demanded service for those attending conferences and events. Let alone the want of customers to have access to the Intenet at their favorite coffee shop. Despite the proliferation of WiFi services several misconceptions still pervade the technology, in this article we will look at the four most common of these misconceptions.
Function vs Service
Many of these misconceptions are encountered when businesses are looking to upgrade their WiFi network. This is then followed by conducting a wireless site survey whose importance is often underestimated due to business leaders lacking an in depth understanding of WiFi. To this extent WiFi is often confused as a service and not a function. Even in the introductory paragraph WiFi was referred to as a service but this is technically incorrect.
Your Internet service is brought to you by a line installed by your Internet Service Provider (ISP). The ability to connect to the Internet over a WiFi connection is a function provided by your hardware that the ISP installs, typically your router. It is true that you can provide WiFi as service to customers while in your business premises but it is the WiFi functionality of your router that will allow them to connect.
Secure WiFi is not necessarily Secure
The Internet can be dangerous place and one of many a hacker’s favourite methods of compromising a network is by unsecured WiFi connections. To this extent several misconceptions exist regarding a secure connection to a WiFi enabled device. The most common of which is that a secure connection is inherently secure, meaning that everything that is done on the Internet is secure. This is not the case.
It is important to remember that while your connection to the device is secure, it then connects to the wider, far more dangerous, Internet. Then what is needed is end-to-end security, as can be found if connecting to an HTTPS connection, or other security and encryption focused protocol. So while your your connection to your router is secure that does not necessarily mean your connection to the Internet is secure.
Signal Strength vs. Signal Quality: What You Need to Know
High WiFi signal strength doesn’t always mean better quality. Sometimes, a 2.4 GHz signal can outperform a 5 GHz signal, even if the latter shows higher strength.
5 GHz signals struggle to travel far and penetrate concrete walls. However, this limitation reduces interference from neighboring devices. Less interference can lead to improved signal quality.
In contrast, 2.4 GHz signals may travel farther and handle obstacles better. Despite having lower signal strength, they can provide a more stable connection in some cases.
To optimize your WiFi, consider both signal strength and quality. Test different frequencies and placements to find what works best in your environment.
Understanding these nuances will help you achieve a better and more reliable connection.
The Curious Case of WiFi Extenders
As is often the case when shortcomings in the WiFi infrastructure are found people will apply the DIY solution of purchasing then installing a WiFi extender. This more often comes with varied results favouring the bad. This is because extenders will broadcast the signal on the same channel as the router and by cutting the capacity of the channel in half in order to cover a wider area. This can also cause high levels of interference further impacting the WiFi connection.
Conclusion
Managing WiFi can be a significant challenge for business leaders and homeowners alike. Conducting a thorough wireless site survey offers a practical solution to these challenges. This survey helps uncover potential issues and misconceptions about your WiFi network. By addressing these problems head-on, you can optimize your network’s performance and avoid common pitfalls. Don’t let WiFi issues become a persistent headache. A comprehensive survey ensures your network operates smoothly and efficiently, ultimately improving connectivity and productivity.
