3G is an older wireless communication technology that provides relatively data transfer rates compared to its successors. It was the first mobile data network to enable internet access on mobile devices and allowed basic browsing, email, and video calling. Maximum theoretical download speeds range from to 42 Mbps. 4G, or Fourth Generation, is a significant improvement over 3G, providing much faster data transfer rates and better overall . It enabled higher-quality video streaming, improved web browsing, and faster downloads and uploads, with maximum theoretical speeds ranging from to 1 Gbps.
5G, the latest generation of wireless communication, offers even higher data transfer rates and lower latency than 4G. It promises to various industries with its high-speed and low-latency capabilities, supporting augmented reality, virtual reality, and Internet of Things applications. Maximum theoretical download speeds for 5G range from to 10 Gbps or more. Meanwhile, Wi-Fi, short for "Wireless Fidelity," allows electronic devices to connect to the internet wirelessly using . With a range of up to 100m outdoors, the Wi-Fi range can vary based on several factors, including router type, frequency band, and physical that may interfere with the signal.
Bluetooth is a short-range wireless technology used for connecting devices in close proximity, typically within a few . It can create a Personal Area Network (PAN) to connect multiple devices, with the user's smartphone often acting as the . Bluetooth’s data transfer rates have improved, with the latest Bluetooth 5.x offering speeds up to . This technology has a wide variety of uses, including wireless audio, smartphones and accessories, home automation, and healthcare applications. While Bluetooth provides convenience and is compatible with many devices, it has limitations such as its range and potential security concerns if not properly secured.
