ZTE joins Huawei with “all good” results from China’s IMT-2020 tests

ZTE has said that tests of high frequency radio access and “massive MIMO”, carried out for China’s IMT-2020 (5G) Promotion Group, have all gone as expected.

The vendor, which is one of those testing technologies in Phase I of the Promotion Group’s, followed Huawei in releasing a few details of successful tests of radio interface technology.

ZTE said it had tested “high frequency” radio access in indoor conditions with both LOS and NLOS conditions, and had seen uplink and downlink throughputs  increase. It did not say at what frequency the tests were carried out, or what air interface was used. Nor did it say what throughputs were achieved. It simply said: “Single-user throughputs in different noise-signal ratios met the expected theoretical result.”

The other line of test was of “massive MIMO” performance. Again, there were no details as to the number of antenna elements in the array, or bandwidths utilised an so on. And no throughput details. However,we were told uplink MIMO could reach gains “four times greater than before.”

The release was short enough on detail to lead one to think the vendor was mainly keen to release a PR highlighting that it, too, is active in the IMT-2020 Promotion Group.
