Pic Qualcomm is preparing to ship a relatively boring piece of the 5G puzzle – well, maybe boring for you, but fascinating for the electronic geeks: a compact transmitter / antenna combo that goes into 5G phones [19659002] Millimeter wave transmissions are a crucial part of next – generation ultrafast mobile broadband, also known as 5G: carriers with millimeter wavebands of several gigahertz can transfer more data per second to the next generation. portable devices The difficulty is that millimeter-wave communications do not have much scope, are quite narrow and focused, and can not penetrate the walls and enter the walls. buildings. A transceiver and an appropriate antenna network on a phone have to do a lot of work – like finding and directing the signal beams no matter how you hold it, and managing the weak signals that bounce off the wires. people, cars, trees and so on – all to maintain a decent connection to the nearest phone mast.
And it must be small enough and weak enough to fit in a smartphone. In fact, it takes more than one for the signals to continue to pass despite the way you hold the phone: your hand will block transmissions from one module, letting others do the work. On Monday, Qualcomm unveiled its 5G millimeter-wave antenna technology and transceiver, both designed to work with the company's Snapdragon X50 modem and integrating into handsets. . Qualcomm's technicians have also worked closely with mast manufacturers, operators, national regulators' communications supervisors and software developers to optimize their 5G equipment and applications for their 5G stack. in the world of radio modems – cough, cough, Intel, MediaTek – know that it works closely with cell phone equipment manufacturers and mobile networks to adjust the positioning and output of their antennas -mast so that the 5G works well with miniaturized Qualcomm. smartphone antenna networks. Qualcomm really wants to be the first to get out of the door with 5G so that the public infrastructure is optimized for its hardware, not its competitors.
The size matters … On the top left is the 5G transceiver module, a Snapdragon X50 chip, and a comparison piece
The QTM052 5G millimeter wave module, we are told, allows fragile millimeter-wave communications to function expected, supporting:
- Beam training – feed signals through tiny antennas to form the wireless signal to propagate in the best direction;
- Beam steering and beam tracking – adapting the shape of the signal to maintain a connection
These, Qualcomm explains, improve both the range and reliability of the signals. The QTM052 modules include a 5G NR transceiver, power management circuitry, RF front-end components, and a phased array of antennas. The modules support up to 800MHz bandwidth in the 26.5GHz spectrum at 29.5GHz, and also cover the 27.5 to 28.35GHz and 37 to 40GHz bands.
Qualcomm estimates that four of the QTM052 units can be packaged in a smartphone. We are told that radio module samples are currently in the hands of the phone designers, and Qualcomm said that it expected device manufacturers to launch QTM052-equipped devices at first half of 2019.
There is also a family of four members of radio modules designed for greater 5G cell coverage, ie outside dense urban areas and indoor environments targeted by the QTM052 devices. The QPM56xx RF module family (QPM5650, QPM5651, QDM5650, and QDM5652) works with the Snapdragon X50 modem to operate in bands below 6GHz:
- The QPM5650 and QPM5651 incorporate a PA / LNA 5G NR (power amplifier, noise amplifier), switching and filtering subsystem
- The QDM5650 and the QDM5652 omit the power amplifier, but add support MIMO (multi-input, multi-output).
Modules include switching designed to optimize massive MIMO applications. covers the bands 3.3 to 4.2 GHz, 3.3 to 3.8 GHz, and 4.4 to 5.0 GHz.
Qualcomm took the opportunity to launch an innovation at Intel, challenger of the Qualy cellular modem. In a blog post this week, Qualcomm claimed that Snapdragon 845-based smartphones have data transfers "up to 192% faster" than non-Android smartphones based on an Intel modem.
Qualcomm does not name the brand of non-Android smartphones – cough, that's Apple's iPhones – it's simply said smartphones using its Snapdragon radio electronics that use Intel XMM 7480 and XMM cellular modems 7360 (really, they mean iPhones: Apple uses a Qualcomm got its numbers from netizens performing about a million tests using the Ookla Internet Speed Test Tool, which collected the numbers, has them The results were obtained from Snapdragon 845-powered droids and Intel-powered mobes on the US AT & T and T-Mobile networks. Signed by Ookla rather than being selected by Qualcomm, Ookla can, we are told, detect the device model and chipset you are using.
Overall, Qualcomm wants the Phone makers are using its chips for cellular connections, and not Intel and MediaTek, regardless of the legal brouhahas components. And he says his business is ahead of the pack. ®
