Test and measurement (T&M) vendor Anite on Thursday said it verified LTE Cat 4 maximum data throughputs in a live LTE network of TeliaSonera.
Average peak throughputs as high as 144 Mbps were recorded in TeliaSonera’s commercial 4G network using Anite’s test platform Nemo Outdoor and a Cat 4 LTE test terminal Samsung Galaxy Note 3. Similar peak data performance was achieved using the HiSilicon-based Huawei E3276 modem.
Anite performed the test by downloading data using the FTP protocol within TeliaSonera’s LTE network. This eliminates problems and bottlenecks caused by factors coming from outside the LTE network and enable the verification of high peak throughputs.
In addition to live networks, Anite’s engineers have previously tested LTE data throughputs in lab environments with ideal radio and core networks recording peak data throughputs as high as 148 Mbps.
“There has been some debate whether LTE Cat 4 maximum data throughput rates can actually be measured with existing wireless network testing systems due to limitations in the user equipment processing power,” said Kai Ojala, CTO of Anite’s Network Testing business.
While testing LTE Cat 4 commercial phones and modems in the field, we have achieved excellent peak data rates using FTP downloads. This clearly demonstrates that maximum peak data rates can be reached and there are no CPU performance limitations in Nemo tools,” Ojala added.
