LTE / LTE+
Long Term Evolution (LTE) is the third-generation mobile communications standard (3.9G). LTE Advanced, also known as LTE+, is the 4G mobile communications standard and is backward compatible with LTE. Compared to LTE, LTE Advanced allows transmission rates of 1000 Mbit/s for downloads and 500 Mbit/s for uploads. LTE+ supports carrier aggregation, which increases the data rate per user and allows network operators to use the available radio spectrum flexibly.
The next step up from LTE Advanced is LTE Advanced Pro, also known as 4.5G, which offers an even higher performance level of over 500 Mbit/s.
The latest 5G mobile communications standard utilises higher frequency ranges to enable data rates of up to 10 Gbit/s, increased data throughput and frequency capacity, and real-time transmissions with latency of less than one millisecond.
History LTE/LTE+
- 1G, A network (1958), B network (1972) and C network (1986) - analog voice transmission
- 2G, GSM standard (1992) - digital voice transmission
- 2.5G, GPRS (2001) - Digital data transmission
- 2.75G, EDGE (2006) - further development of GSM
- 3G, UMTS (2004) - simultaneous sending and receiving of several data streams
- 3.5G, HSPA (2006) – Erweiterung von UMTS
- 3.9G, LTE (2010) - is based on the UMTS infrastructure
- 4G, LTE + (2014) - LTE expansion stage, change to fourth generation of mobile communications
- 5G, (2020/21) - fifth generation of mobile communications, real-time transmissions possible
