Huawei, Qualcomm and China Mobile verify 4.5G compression tech

News

Huawei has completed a commercial test of new LTE-A compression technology with China Mobile and chipset maker Qualcomm.

Huawei said Uplink Data Compression (UDC) tech allowed operators to increase the number of uplink users on LTE-TDD networks, improving the compression efficiency of web applications and browsing.

According to the vendor, UDC works by compressing uplink data at the LTE lower layers, based on conditions such as application traffic.

This reduces the consumption of uplink resources and increases capacity by up to 50 percent as a result. 

UDC can also improve web surfing for mobile users in areas with weak mobile signal, Huawei said.

According to the vendor, UDC can be easily deployed without hardware upgrades: operators only need to upgrade their Evolved Node B (eNB) software.

Additionally, the technology is based entirely within in the LTE modem, meaning it is independent of a mobile phone’s OS. 

UDC forms part of a range of new technologies Huawei is labelling TDD+, which the vendor said was “a key part of 4.5G”, otherwise known as LTE-A.

TDD+ is aimed at increasing the broadband speeds to “x-GBps levels” based on LTE-TDD capabilities such as massive Multiple-Input Multiple Output, 3D Beam-forming, 256QAM, and User Data Convergence.

Qualcomm’s upcoming LTE modems are expected to support UDC later this year, with Huawei’s eNB solutions also prepped for commercial release at the same time. 

Other 4.5G technologies from Huawei include “LTE-M”, which the vendor recently used to create a smart parking network for China Unicom in Shanghai.
