Wi-Fi and the Internet have become an indispensable part of our daily lives. Because of the importance and convenience of a business Wi-Fi network, it is now a must-have service for most businesses. Unfortunately, numerous small-to-medium-sized businesses lack the resources and cyber skills required to appropriately secure their networks. This can be a major issue because an unsecured network exposes the company to attacks from hackers looking to steal valuable company information or customer data. How Can Businesses and IT Leaders Strengthen Their Wi-Fi Security? A data breach can cripple your business. It not only undermines consumer trust, but data breaches cost an average of $4.24 million. Fortunately, improving your Wi-Fi security is not difficult. To safeguard your company's wireless Internet connection, follow the steps outlined below. Use Up-To-Date Wi-Fi Encryption You should upgrade your hardware if it can only support WEP or WPA encryption. The Wi-Fi Alliance strongly encourages the widespread use of WPA2. Cutting-edge encryption has been demonstrated to be protected against even the most persistent attackers when correctly implemented. If you run an enterprise environment, you should take advantage of the extra security provided by specific digital certificates. Encrypt Wi-Fi Router Administration Pages Taking your Wi-Fi security a step further needs the use of a Wi-Fi digital certificate to secure your admin login pages. Self-signed certificates that come pre-installed on a few routers are untrusted, easy to copy, and prone to Man-In-The-Middle (MITM) attacks. TLS certificates from reputable certificate authorities can ensure that all of your Wi-Fi connectivity is safe and confidential. If your router's quick start guide does not contain digital certificates, you can obtain information on the manufacturer's support page. Consider Restricting MAC addresses Smaller network managers can lock down MAC addresses for more control. Wireless routers and access points use MAC (Media Access Control) address filtering to block attacks. Every WiFi-enabled device has a unique MAC or physical address and a list of connected devices. You can manually enter addresses to define network access, but hackers can fake MAC addresses. Use Always-On SSL You must utilize HTTPS across your website and apply it to Wi-Fi. Accessing an account on an encrypted page and subsequently interacting with the site through unencrypted pages exposes the user to session-side jacking. Create a Guest AP with Tighter Security Not all businesses must enable guests or customers to connect to their networks, but some companies do offer guests access by providing them with guest login credentials. If your company falls into this category, set up a dedicated guest AP that is isolated from the rest of the company network. You can set up a second AP on your router and utilize a firewall to limit access from that AP to certain services that you want your visitors to be able to access. Closing Lines Nowadays, having an internet connection is critical for organizations, as is keeping it secure from hackers. Moreover, when conducting business, it is crucial to keep critical information and customer data secure. Otherwise, you risk compromising your company's image. So, if you want to maintain your Wi-Fi network security and keep your business working effectively, you must adhere to a few fundamental principles. Finally, you are on the path to make your Wi-Fi network safer and more robust by following all of these techniques at once or step by step.

Antennas are fundamental to the performance of connected devices, but are often implemented as an afterthought, resulting not only in sub-optimal performance, but also in less-than-ideal form factor. It can also have a negative impact on cost for the device as a whole. It is therefore essential that organisations prioritise antenna design as part of a holistic device design philosophy – bear in mind that it is practically impossible to fix bad antenna design. Early decisions need to be made regarding the relative merits of embedded or external devices and then attention can turn to optimising antenna integration.

5G is a little higher at 3.4GHz to 3.6GHz, but that's tiny when you consider that microwaves go up to 300GHz. And visible light comes in at a range of around 430THz to 770THz. That's more than a thousand times higher than the maximum microwave – and 100,000 higher than 5G. Dangerous radiation, like UV rays, X-rays and gamma rays are also far higher up the spectrum still. Early theories suggested 5G could lead to cancer – and now crackpots have linked it to coronavirus too. But it's simply impossible for 5G to cause any of these problems. Radiation damages cells by breaking them apart, but 5G microwaves simply lack the power to do this. 5G is a low-frequency radiation, far below infrared and visible light. In fact, it's essential that 5G is low-frequency, because higher frequencies are less useful at delivering mobile signals over large areas. We know that this level of radiation is safe, because otherwise the visible light from our televisions would have killed us a long time ago.
