What is the current state of WiFi technology, and what are its limitations?
WiFi technology has come a long way since its inception, with the latest WiFi 6 standard offering faster speeds, better performance, and increased capacity. However, despite these advancements, WiFi still has its limitations. One of the main limitations of WiFi is its reliance on radio waves, which can be prone to interference from other devices and physical barriers. This can result in dropped connections, slow speeds, and poor overall performance.
Another limitation of WiFi is its range, which can be limited by the strength of the signal and the presence of physical barriers. This can make it difficult to maintain a stable connection in large areas or in areas with many obstacles. Additionally, WiFi networks can be vulnerable to security threats, such as hacking and eavesdropping, which can compromise the security of devices connected to the network.
What are some of the emerging wireless technologies that are faster than WiFi?
There are several emerging wireless technologies that are faster than WiFi, including Li-Fi, WiGig, and 5G. Li-Fi is a technology that uses light to transmit data, offering speeds of up to 224 Gbps.
