LTE, or Long-Term Evolution, is a standard for wireless broadband communication. It is widely used for mobile devices, providing high-speed internet access and improved data transfer rates compared to previous technologies like 3G. LTE supports various applications, including video streaming, online gaming, and web browsing, making it essential for modern mobile connectivity. The technology operates on different frequency bands and utilizes advanced techniques such as MIMO (Multiple Input Multiple Output) to enhance performance. LTE networks are designed to be more efficient, allowing users to experience faster download and upload speeds, lower latency, and better overall service quality in their mobile communications.
