Qualcomm's X24 Modem Pushes 4G LTE to 2Gbps

14 February, 2018, 19:17 | Author: Rolando Keller

"Qualcomm Technologies is deeply committed to helping our customers deliver next-generation 5G mobile experiences to consumers, which requires enhanced mobile broadband 5G NR connectivity enabled by 5G NR networks, mobile devices and the Snapdragon X50 5G modem", said Alex Katouzian, senior vice president and general manager, mobile, Qualcomm Technologies, Inc.

It supports up to 7x carrier aggregation in the downlink, as well as 4×4 MIMO on up to five aggregated LTE carriers, for a total of up to 20 concurrent spatial LTE streams. Last week, the company announced that its Snapdragon X50 would enter testing this year with carriers around the world and feature in 5G phones beginning next year. Well, Qualcomm is targeting the Snapdragon X24 LTE as a form of gateway drug into 5G, offering speeds the next-generation mobile broadband looks to offer but on 4G.

Qualcomm's Product marketing director Sherif Hanna told Vulture South network services and devices are now expected in the first half of 2019, with a little snark for current "5G" demonstrations (without specifically naming the test at the Pyongchang Winter Olympics). This, in turn, opens the door to better performance than what we have now, though since your network speeds aren't just dependent on the modem in your phone, it might be best not to expect 2Gbps speeds from phones utilizing an X24 at all times.

All that speed means blisteringly fast mobile connections for streaming and other online activity; we'd imagine porn aficionados could get hold of some much grot that they'd break themselves.

Winter Storm Forecast Improving; Nearly 7 Inches Today, 10+ By Sunday
Thousands of children got a rare snow day off school after school districts in Chicago, Detroit and Milwaukee canceled classes. When all's said and done, forecast models project Buffalo could see 5 to 7 inches of total snowfall by the end of the weekend.

When we first got 4G in 2011, 5-10Mbps speeds were common on Verizon's LTE network. The Snapdragon X20 is claimed to deliver download speeds of up to 1.2Gbps and is built on the commonly found 10nm process. But the fact that Qualcomm has announced this modem at all shows that it believes there's going to be demand for an advanced LTE solution in smartphones next year that does not include 5G connectivity, and that seems like a reasonable prediction to me.

The X24 is still a 4G chip, but it features Full Dimension Multi-Input Multi-Output (FD-MIMO) antenna technology that is a key foundation of future 5G NR (New Radio) networks - 5G NR is the global 5G standard.

In the uplink, the X24 supports Category 20 upload speeds, 3x20MHz CA and up to 256 QAM encoding.

Original equipment manufacturers (OEMs) can offer better mobile experiences such as 360-degree video, connected cloud computing, more entertainment and instant apps. At the same time, operators can gain flexibility in using their spectrum assets to offer blazing fast speeds to consumers, while also improving their network capacity and maximizing spectral efficiency.
