Long Term Evolution (LTE) is a wireless communication technology used for mobile data transmission. It mainly provides fast data and audio/video calling services for mobile phones, tablets and other smart devices. To understand how LTE works, the following key elements can be looked at:
1. Wireless signal transmission:
LTE uses frequency bands. It uses Orthogonal Frequency Division Multiplexing (OFDM) technology. This is a method of sending data using multiple frequency channels, which allows multiple users to send data at the same time.
2. Multiple Input, Multiple Output (MIMO):
LTE uses MIMO technology, which uses multiple antennas to increase data signal speed and improve signal strength. This allows multiple data streams to be sent simultaneously, increasing network capacity.
3. IP (Internet Protocol) based systems:
LTE is an IP-based system, which means that all types of communication (data, voice, video) use the same network protocol. This simplifies network management and provides improved quality of service for voice and video calls.
4. Reducing latency:
A major advantage of LTE networks is their low latency, which means users get faster responses, especially important for video conferencing, online gaming, or real-time applications.
5. Basic Structure:
Evolved UMTS Terrestrial Radio Access Network (E-UTRAN): It controls the signal transmission system between LTE base stations and the network.
Evolved Packet Core (EPC): It is the core part of the LTE network that handles communication and data routing between different parts of the network.
6. Superior data speed:
LTE offers much faster download and upload speeds than conventional 3G technology. Typical LTE networks offer download speeds of up to 100 Mbps and upload speeds of up to 50 Mbps.
7. Internet services:
LTE provides powerful services for mobile internet. It is ideal for high-speed browsing, streaming video, and online gaming.
Conclusion:
LTE works by using advanced technologies, particularly OFDM and MIMO, to allow multiple users to transmit data simultaneously and at high speeds, providing a robust and fast network experience with low latency.
