LTE

 LTE (Long-Term Evolution) is a wireless network technology used to provide high-speed internet access to mobile devices. It is a standard for 4G (fourth-generation) cellular networks that offer significant improvements in data transfer rates, latency, and overall network capacity compared to earlier 3G technologies.

LTE uses a technique called Orthogonal Frequency Division Multiplexing (OFDM) to divide the available frequency spectrum into multiple smaller sub-carriers, which can be used by multiple users simultaneously. This allows for a more efficient use of the available bandwidth and supports high-speed data transfer rates of up to 1 Gbps (gigabit per second) on the downlink and up to 500 Mbps on the uplink, depending on the network configuration and the capabilities of the device.

LTE has been widely adopted by mobile network operators around the world and is now the dominant technology for mobile broadband networks. It has been further enhanced by LTE-Advanced (LTE-A) and LTE-Advanced Pro (LTE-A Pro), which provide additional features such as carrier aggregation, higher-order MIMO, and support for unlicensed spectrum bands.
