Huawei Spain and Orange Reach Download Speeds of More Than 1.5 Gbps on a 4.5G Network

Huawei Spain and Orange have surpassed download speeds of 1.5 Gbps on a 4G network, during tests in Valencia. This achievement has been obtained using Huawei’s equipment integrated into the Orange 4.5G network. Specifically, Huawei has deployed a LTE solution based on the 3GPP LTE Advanced Pro standard. As seen in the image below, the average speed obtained was 1.54 Gbps.

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.

Some of these technologies (such as aggregation of multiple bands, or using TDD), along with massive NxN MIMO, will likely be present in 5G mobile phones whose standards are still under discussion.

To date, there are no commercial devices supporting these speeds, but they are expected to be available from 2018.

The experience in Valencia is a demonstration of the capacity growth in download speeds and the potential capacity of 4.5G networks in the future. As consumers’ traffic demands increase, Orange will expand the capacity of its 4.5G network by adding more carriers and using new frequency bands on the radio spectrum.

The Orange network in major urban areas of Spain already has 2.4G carriers, and 3G in areas of high consumption or hotspots. Over time, this capacity will be extended to 4G or 5G carriers depending on traffic demand.
