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

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

"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", said Alex Katouzian, Senior Vice President and General Manager for Mobile of Qualcomm Technologies. Qualcomm expects its 2Gbps modems to pull down real-world averages between 200 and 600 megabytes per second, or Mbps. While many service providers have begun working on gigabit LTE in earnest, the faster network still isn't completely deployed nationwide. This unprecedented feature set is created to allow devices that feature the Snapdragon X24 LTE modem to utilize all spectrum assets available from a mobile operator, whether in licensed spectrum, or with License Assisted Access (LAA).

As we continue to march towards 5G, the technology for gigabit LTE continues to be an important part of mobile data.

Qualcomm says the new X24 LTE modem can reach theoretical speeds of 2Gbps, wherever supported by carries, which is a significant improvement over theoretical speeds of 1.2Gbps achieved by X20 LTE modem.

Former Celtic star John Hartson, who himself battled cancer, tweeted his condolences, adding, "Rest in peace young man". Celtic held a minute's silence in tribute to former midfielder Liam Miller , who died at the age of 36 .

The chipset giant has already started sampling the modem, with devices expected to hit the market by the end of 2018. That could create an opportunity for other smartphone makers to differentiate their devices with the Snapdragon X24, but to do that they will need to build products that can support what the chip has to offer, including massive MIMO, carrier aggregation, 256-QAM and license-assisted access. "We're excited to demonstrate these advancements at Mobile World Congress and showcase how our technologies are created to expand the reach of 5G NR to new industries, new deployment and business models, and new ecosystem participants".

The new Snapdragon X24 can support up to seven times carrier aggregation and 4x4MIMO on up to five different bands on downlink. There is also full-dimension Multi-Input Multi-Output (FD-MIMO) to give way to carriers to start sending their 5G signals.

Following the world's first 1Gbps speeds demonstration in November 2015 and the first commercial Gigabit LTE network launch in January 2017, this latest technology breakthrough accelerates joint efforts by Ericsson, Telstra, Qualcomm Technologies and NETGEAR to deliver the world's leading Gigabit LTE network, paving the way for increased capability and performance on the journey towards 5G.

Dozens dive into cold Deschutes for Bend's Polar Plunge
Over the years, the plunge has raised as much as $35,000, Scotts Bluff County Sheriff Mark Overman said. In addition to the polar plunge, there was a silent auction, costume contest and fundraising awards.

Original equipment manufacturers (OEMs) can offer better mobile experiences such as 360-degree video, connected cloud computing, more entertainment and instant apps.

The chipset maker said the product, its eighth LTE multimode modem and third generation Gigabit LTE product, would pave the way for 5G New Radio products. Operators will also be able to use their spectrum more efficiently while delivering high speeds to consumers.
