What is WiFi and how does it work?
WiFi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It works by transmitting data through radio waves at a specific frequency, typically in the 2.4 gigahertz or 5 gigahertz range. WiFi routers, which are usually connected to a physical internet source, transmit these radio waves, which are then received by devices equipped with WiFi adapters.
WiFi is commonly used to provide internet access in homes, offices, and public hotspots. It’s a convenient and widely adopted technology that allows devices to move freely while maintaining a connection to the internet. However, WiFi signals can be weakened by physical barriers, such as walls and furniture, and can be disrupted by interference from other devices. This can impact the speed and reliability of WiFi connections.
What is LTE and how does it work?
LTE (Long-Term Evolution) is a type of wireless communication standard used for high-speed wireless communication of data and voice. It’s a 4G (Fourth Generation) technology that allows for rapid data transfer rates, making it ideal for mobile devices such as smartphones and tablets. LTE works by dividing the data to be transmitted into small packets and assigning each packet a unique identifier. The packets are then transmitted over the LTE network, which is comprised of cell towers that provide coverage over a specific geographic area.
LTE is commonly used by mobile carriers to provide fast and reliable wireless data services to their customers. It’s designed to support high-bandwidth applications such as video streaming and online gaming, and is generally considered to be more reliable and faster than older 3G (Third Generation) technologies.
