Wifi performance in smartphones analysed

Investigation requested: Broadcom versus Qualcomm


Test setup

In the base we use a part of the same test setup that we also use when testing routers. Using Ixia's IxChariot software, we send a so-called TCP High Performance script from the router to the relevant smartphone (Lan-Wlan) and vice versa (Wlan-Lan), where we measure the speed. As usual, we perform these tests twice in a row, noting the average score. We then repeat the whole process on another day and at a different time in order to rule out any extremes. The values shown in the tables are the average results of several tests.

Obviously we tested all participants as far as possible on both the 2.4 and the 5 Ghz band. The Honor 6X, Wileyfox Swift 2 X, Huawei Y7, Motorola Moto E4 and E4 Plus all do not support the 802.11ac standard and are therefore only tested on the lower frequency. These are - with the exception of the Honor 6X - not entirely coincidental also the cheapest devices in the field.

Before we look at the translation of the test results, just one more point of order: the test results we are referring to are the average values of the Lan-Wlan and Wlan-Lan tests together, on the 2.4 GHz or 5 GHz band in combination with either the R7800 or the R8000. These average scores are shown in the tables attached, all individual partial scores can be found in the overview table on page 75.
