When the 5G revolution hit smartphones, MediaTek was quick to embrace the emerging wireless standard with integrated 5G SoCs for smartphones. However, the company's 5G modems up until this point have only supported sub-6GHz 5G networks, and not the faster (but admittedly less prevalent) mmWave bands. That all changes with the announcement of MediaTek's new M80 5G modem which supports both sub-6GHz and mmWave 5G into a single-chip design. This puts MediaTek on more even footing with its rivals Samsung and Qualcomm, which have both field sub-6GHz/mmWave solutions in a single chip. The M80 is the successor to the Helio M70, which is currently embedded in MediaTek's Dimensity 5G SoCs.... Read more...
It seems Pete Lau and his company, OnePlus, continually strive to innovate with new mobile phones. With every new device, feature, and design, OnePlus pushes the envelope just a little further. Now, the trend is continuing with the unveiling of the OnePlus 8T Concept, a phone designed to "create a more natural interaction between users and the device." At CES 2020, OnePlus unveiled its experimentation with "color-shifting glass technology," which allowed for a disappearing camera feature. Though it may have been an expensive technology at $9,100 for the add-on, it is clearly still worth investigating. Rather than merely hiding a camera, however, OnePlus decided to "craft new interaction experiences... Read more...
We have all heard the tantalizing promises of 5G connectivity—faster speeds, lower latency, and a new era of experiences made possible by its benefits over 4G and earlier standards, if you have a 5G phone or other device. The problem is that those benefits do not necessarily reach their full potential indoors. That is where Samsung's new Link Cell technology comes into play. When it comes to 5G connectivity, millimeter Wave (or mmWave) is where it is at, for the fastest performance. It is the high band solution with the best speeds, but it has some downsides. It does not extend as far out from cell towers as mid-band and low-band 5G solutions, and can have issues penetrating buildings and... Read more...
Apple is on track to announce its new iPhone 12 family sometime this month, or perhaps in early October. Given testing delays that cropped up due to COVID-19, the latest iPhones are launching a few weeks later than previous models. With that being said, one spec that has seemingly been confirmed for all of the upcoming iPhones is 5G support, but a new report is shedding light on to what exactly that will entail. According to sources for Fast Company, only the iPhone 12 Pro Max will have mmWave support. The iPhone 12 Pro Max is the largest of the incoming smartphones, and features a 6.7-inch OLED display (1242 x 2688). Allegedly, only the iPhone 12 Pro Max has enough space inside its chassis...

AT&T has announced the next big step for its growing 5G network: nationwide availability. By the company’s own estimates, its 5G network is currently spread across nearly 400 U.S. markets and blankets just over 250 million Americans. As far as we can tell, AT&T thankfully isn’t including its controversial and misleading 5GE wireless coverage (which is basically just a fancy name for 4G LTE-Advanced) in its 5G declaration. Instead, AT&T says that its ultra-fast mmWave 5G technology is available in 35 markets. Its sub-6GHz “low-band” 5G spectrum is used to cover the rest of the nation (crucially, outside of large city centers). “With AT&T 5G reaching... Read more...
Qualcomm has rolled out the world's first fully-integrated 5G NR millimeter (mmWave) and sub-6 GHz RF modules for smartphones and other mobile devices. The new chips include the QTM052 mmWave antenna and the QPM56xx sub-6GHz RF module family. The new chips have a compact footprint, pair with the Snapdragon X50 5G modem, and deliver modem-to-antenna capability across several spectrum bands.  "Qualcomm Technologies’ early investment in 5G has allowed us to deliver to the industry a working mobile mmWave solution that was previously thought unattainable, as well as a fully-integrated sub-6 GHz RF solution," said Cristiano Amon, President, Qualcomm Incorporated. "With 5G, consumers can... Read more...
The race towards gigabit Internet continues as Google Fiber slowly proliferates and other ISPs work to catch up, but Samsung announced that it’s actually looking at gigabit speeds--for mobile devices. Indeed, Samsung says it has been testing a 5G mobile communications system, the eventual successor to 4G LTE that is capable of up to 1Gbps. The 5G technology, dubbed mmWave, runs in millimeter Ka bands and requires a “broad range” of frequencies but operates at 28GHz, delivering up to 1.056Gbps for up to 2 kilometers. It uses adaptive array transceiver technology with 64 antenna elements. (Image credit: variety.thaiza.com) Of course, this is all in the testing phase, so don’t... Read more...
