Long Term Evolution (LTE) is the name of the third generation mobile radio standard, 3.9G. The extension, LTE +/LTE Advanced, describes the 4G mobile radio standard, which is downward compatible with LTE. Compared to LTE, LTE+ allows transmission rates of 1000 Mbit/s or 1 Gbit/s download and up to 500 Mbit/s upload. LTE + supports carrier aggregation (increasing the data rate per user), which allows network operators to use the available radio spectrum flexibly. The upgrade from LTE+ is LTE Advanced Pro, which is also called 4.5G and offers an even higher level of performance (with over 500 Mbit/s).

With the latest 5G mobile radio standard, higher frequency ranges are now also used, meaning that data rates of up to 10 Gbit/s, increased data throughput and frequency capacity, real-time transmissions and latency times of even less than a millisecond are possible.


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
