According to Apple, the 4G LTE of the iPhone XS is improved. If you are part ofdying users to get as much detail as possible about the 4G LTE performance of the iPhone XS and iPhone XS Max, a test shows us the advantages of the added value by Apple to the modems of the iPhone XS.
SpeedSmart, a service that lets you test the speed of your wireless connection, has published its first tests of the iPhone XS 4G LTE speed on the three main American operators (AT&T, T-Mobile and Verizon). The test confronts the iPhone XS and the iPhone X. In this test, it would seem that the iPhone XS has made considerable gains compared to the iPhone X. This is simply due to the fact that Apple added the MIMO 4 × 4 (which can offer a speed capable of exceeding 1 Gb / s) for its iPhone XS. Unfortunately, the iPhone X, the iPhone 8 and the iPhone 8 Plus and even the iPhone XR do not carry the MIMO 4 × 4, they are equipped with the MIMO 2 × 2. This means that you will unfortunately not see these improvements on an iPhone XR (unless you have an iPhone XS or iPhone XS Max).
Besides the 4 × 4 MIMO, the iPhone XS and iPhone XS Max also support QAM and LAA, which are other radio technologies that will help improve the speed and performance of 4G LTE new phones.
The first pre-orders for the iPhone XS and XS Max will arrive this Friday, September 21, possible tests of this kind will undoubtedly appear on the web; the opportunity will be for us to confirm the veracity and standardization of this test (although the results will obviously vary depending on the network).
