Huawei Spain and Orange reported download speeds of 1.5 Gbps on a 4.5G network, during tests in Valencia.
Huawei deployed a LTE solution based on the 3GPP LTE Advanced Pro standard. The average speed obtained was 1.54 Gbps.
Huawei said this milestone has been made possible by technological advances on LTE-Advanced Pro (also called 4.5G), which include:
- Carrier aggregation up to 5 frequencies of 800, 1800, 2600 and 3500 MHz.
- Simultaneous use of FDD (Frequency Division Duplex) and TDD (Duplexing Time Division).
- MIMO (Multiple Input, Multiple Output) 4x4 (4 transmission paths, 4 reception).
- 256QAM modulation, which allows for the sending of more bits in the same radio spectrum.
