Qualcomm's Next 5G Modem Supports T-Mobile 5G
Qualcomm's new X55 standalone modem chip supports 5G in all major frequency bands as well as FDD and TDD modes. Support for FDD makes it the first chip to support T-Mobile's planned 5G network in the 600 MHz band. Qualcomm's first 5G modem chip, the X50, only supported TDD modes. Verizon, AT&T, and Sprint all have TDD (unpaired) spectrum they will use for some or all of their initial 5G deployment. T-Mobile is focused on its existing FDD bands for 5G. The X55 also includes both 5G and 4G, and is the first chip to support Cat. 22 LTE, offering up to 2.5 Gbps speed. Furthermore, it supports dynamic spectrum sharing between 4G and 5G, for carriers planning to use existing cellular bands for both 4G and 5G simultaneously. The X55 also supports both SA (standalone) and NSA (non-standalone) 5G networks. The X55 can deliver speeds up to 7 Gbps down (and 3 Gbps up) on 5G networks. Qualcomm also introduced a new front-end 5G solution designed to work with the X55, providing the other components needed for 5G. These include a new mmWave antenna that supports band 258 (26 GHz), and is thinner than the current model, allowing 5G phones as thin as 8mm. The X55 and companion parts will appear in commercial devices by "late 2019".

Qualcomm today announced the Snapdragon 865, its new top-end chipset to power flagship phones in 2020. Unlike most previous Snapdragon chips, the 865 is split into two physical chips: the main processor chip and a separate radio modem chip that includes a 5G modem based on the company's X55 5G modem.

Qualcomm today revealed the full details of its first Snapdragon chip with an integrated 5G modem, the Snapdragon 765. As its model number suggests, it offers better performance than the company's 6-series chips that have previously been common to higher-end (but not "flagship") phones in the US.

Qualcomm and T-Mobile have successfully completed the first data call using Qualcomm's X55 modem, the first 5G chip for phones to support all 5G networks to be launched in the US in 2019, including T-Mobile's band 71 (600 MHz). All 5G phones currently on the market in the US use the X50 chip, which only supports mmWave bands and TDD bands such as Sprint's band 41.

"T-Mobile now has the largest swath of unused low-band spectrum in the country," said T-Mobile CEO John Legere about the company's 600 MHz auction winnings. The company successfully won an average of 31 MHz (ranging between 20 MHz and 50 MHz) of the 70 MHz low-band spectrum auctioned off by TV stations and the FCC.
