Qualcomm has prepared a new Snapdragon X75 5G mobile modem for release. During its development, engineers carried out a small reorganization of components and implemented a combined receiver of mmWave and up to 6 GHz bands. The new architecture takes up 25% less space on the printed circuit board and consumes 20% less power.
The novelty is compatible with versions 17 and 18 of the 3GPP specifications, which set standards for the next stages of development of 5G technology. Version 18 in particular marks the beginning of the 5G Advanced stage, which will significantly expand the scope of 5G applications, for example, for connected cars and cities.
Qualcomm Snapdragon X75 5G provides wider support for 5G carrier aggregation. This technology allows you to combine frequencies for sending and receiving data, thereby increasing the transmission speed. The new chip supports 5-carrier aggregation at up to 6 GHz and 10-carrier aggregation in the mmWave range.
The modem is able to process 5G/4G data simultaneously on two SIM cards. Support for Snapdragon Satellite technology is also reported, which should provide the possibility of satellite communication.
The Qualcomm Snapdragon X75 5G supports uplink 5G MIMO (Multiple Input Multiple Output) and can send two signals simultaneously using FDD (Frequency Division Duplex – a technology for sending and receiving data at the same time). All this should ensure faster connections, but operators are still only beginning to study and implement these advanced technologies.
The updated firmware of the chip is designed to improve the connection in situations where the smartphone is in a place with poor signal quality, for example, an elevator, a garage or a subway train. According to Qualcomm, the software uses context to determine the most suitable network cell to maintain a better connection when moving. The 2nd generation II accelerator helps improve location accuracy in challenging environments such as dense urban areas.
The new Qualcomm Snapdragon X75 5G mobile modem is currently undergoing testing. It should appear in consumer devices in the second half of 2023.
