Can't wait for 5G? How your next phone goes supersonic in 4G

The latest mobile modem from Qualcomm promises "fibre-like" speeds of up to 2Gbps.

The Snapdragon X24 chip is set to be the world's first Cat 20 modem to make it out into the wild and will boast "fiber-like" internet download speeds of up to 2Gbps. The Snapdragon X24 supports up to 7x carrier aggregation in the downlink, as well as 4×4 MIMO on up to five aggregated LTE carriers - both mobile industry firsts - for a total of up to 20 concurrent spatial LTE streams.

The new modem is built on a 7-nanometer FinFET manufacturing process, an impressive feat on its own that could lead to additional energy efficiency gains.

That's a lot of jargon, but here's the key takeaway: the X24 can sustain high peak download speeds even on congested networks.

"The wireless industry is going to compete on LTE network into the next decade", T-Mobile Chief Technology Officer Neville Ray said on a call with analysts last week.

So what's the point? "The Snapdragon X24 LTE modem sets a major mobile industry milestone, created to provide enhanced mobile broadband and deliver an extremely important gigabit coverage layer for commercial 5G networks and mobile devices that are expected to start launching in 2019".

X50 modems are expected to hit commercial devices in the first half of 2019.

The list of global operators supporting Snapdragon X50 5G Modem for Mobile 5G NR Trials in 2018 includes AT&T, Sprint, Verizon (USA), BT (UK), China Telekom, China mobile, China Unicom - from guess where - China, Deutsche Telekom (Germany), KDDI, NTT Docomo (Japan), Korea Telekom, LG Uplus SK Telekom from Korea, Orange, Vodafone (many countries in Europe), Telecom Italia mobile (TIM) and of course Australia's jewel Telstra. As evidenced by our work with these distinguished OEMs from around the globe and as we demonstrated in 3G and 4G LTE, Qualcomm Technologies is utilizing our deep expertise and technology leadership to support the successful launch of 5G NR, driving innovation in the mobile ecosystem.

The X24 is Qualcomm's third-generation Gigabit LTE modem and will offer a 2x speed boost over its first-generation chip, the company says, enabling devices to better support intensive mobile functionality, including 360-degree video, "instant apps", and richer entertainment. The X24 LTE will be an upgrade over X20 LTE modem found on company's flagship Snapdragon 845 mobile platform. Today Qualcomm announced its newest LTE modem for smartphones ahead of Mobile World Congress. It supports Full Dimension Multi-Input Multi-Output (FD-MIMO), a Massive MIMO technology that is foundational to 5G NR networks. On the upstream side, the modem supports 3x20 MHz carrier aggregation and 256-QAM for upload speeds up to 316 Mbps.
