16 sty 2011 · Long Term Evolution (LTE) is the next generation of mobile broadband technology that provides higher data rates and network throughput compared to 3G. LTE networks use OFDM and SC-FDMA for downlink and uplink, respectively, along with MIMO and an all-IP architecture to improve performance.
7 lis 2014 · LTE – Basics. What is LTE ? • 3GPP Long Term Evolution, referred to as LTE and marketed as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using new modulation techniques.
The tutorial explains the basics of the LTE radio interface, covering OFDM in the downlink, SC-FDMA in the uplink, scheduling, and link adaptation. It also provides examples of multi-antenna transmission techniques and discusses spectrum flexibility and peak rates in LTE.
