Qualcomm marked the upcoming Mobile World Congress with the announcement of its latest Snapdragon X75 modem. It replaces last year’s X70, which is used in Snapdragon 8 Gen 2 smartphones such as the Samsung Galaxy S23 Ultra and OnePlus 11. Qualcomm’s new modem is compatible with 5G Advanced networks, provides more stable connections and uses artificial intelligence to stay connected. in places with poor coverage and poor communication quality.
The Snapdragon X75 is compatible with revisions 17 and 18 of the 3GPP specifications, which set the standard for the next evolution of 5G technology. These specifications, in particular, mark the beginning of the Advanced phase of 5G network deployment, which will greatly expand the geography of 5G from connected cars to cities.
Qualcomm has redesigned the X75 with a combined 5G millimeter wave (mmWave) transceiver with increased speed and bandwidth, and a sub-6GHz (sub-6GHz) band designed for wide coverage and macro network building. The new modem is 25% smaller and consumes 20% less power than its predecessor.
The Snapdragon X75 also has broader support for 5G carrier aggregation, combining frequencies to send and receive data faster. The new chip supports five-carrier aggregation below 6 GHz and ten-carrier aggregation in the millimeter wave band.
The X75 modem supports 5G MIMO (multiple input multiple output) uplink and can send two signals at the same time using FDD (Frequency Division Duplex). All this in the future will lead to a significant increase in the speed and reliability of the connection, but so far telecom operators are just beginning to study and implement new technologies with aggregation of three carriers. We are not talking about the aggregation of five carriers in the near future.
The new modem’s software is designed with a focus on improving connectivity in places with poor signal quality and strength, such as elevators, garages or subway trains. The context is used when searching for the most suitable cell for the optimal roaming connection. And the second-generation AI accelerator helps improve location accuracy in challenging environments such as dense urban high-rises.
Snapdragon X75 is currently in the testing phase and will not be installed in devices until the second half of 2023. Of course, this modem will appear in many Android smartphones, but whether this chip or its custom version will get into future iPhones is still unclear.
