Study Notes
- LTE (Long-Term Evolution) is a wireless data communication technology developed by ETSI, with contributions from various nations and companies, aimed at increasing capacity and speed using new DSP techniques and modulations, and simplifying the network architecture to an IP-based system.
- LTE is incompatible with 2G and 3G networks, requiring separate radio spectrum, and was first proposed in 1998 with studies on the use of COFDM in the L band at 1428 MHz.
- The LTE standard was finalized in December 2008, and the first publicly available LTE service was launched by TeliaSonera in December 2009, with major North American carriers following suit in 2010.
- CDMA operators initially planned to upgrade to rival standards like UMB and WiMAX, but have since announced their intentions to migrate to LTE instead.
- LTE Advanced was standardized in March 2011, with services commencing in 2013, and further evolution known as LTE Advanced Pro approved in 2015.
- LTE supports fast-moving mobiles, multi-cast and broadcast streams, and scalable carrier bandwidths from 1.4 MHz to 20 MHz, with both FDD and TDD options.
- The IP-based network architecture, called the Evolved Packet Core (EPC), is designed to replace the GPRS Core Network, supporting seamless handovers to older network technologies such as GSM, UMTS, and CDMA2000.
- LTE-TDD (Time-Division Duplex) is one of two mobile data transmission technologies of the LTE standard, co-developed by an international coalition of companies, and uses a single frequency for uploading and downloading data through time, with frequencies ranging from 1850 MHz to 3800 MHz and a cheaper and less trafficked spectrum.
