In view of the different plans of global operators for 5G deployment, the Snapdragon X65 5G modem and radio frequency system also adopts an upgradeable architecture, which can quickly realize the support for Release 16 features in batches. This advantage can extend the life of the Snapdragon X65. , It will be of great help to control the total cost.
Based on the new power-saving technology defined by 3GPP Release 16, Qualcomm has launched Qualcomm 5G PowerSave 2.0, which can achieve excellent energy efficiency, such as wake-up signals for networked states. In addition, Qualcomm’s broadband envelope tracking solution and the baseband of the 4nm process can better save power.
Qualcomm Smart Transmit 2.0, used in conjunction with the Snapdragon X65 5G modem and radio frequency system, is a unique system-level technology licensed by Qualcomm Technologies. By using the system sensing function from the modem to the antenna, it can continue to meet the radio frequency transmission requirements while being millimeters. Wave and Sub-6GHz frequency bands bring higher upload rates and wider network coverage.
The innovation of the Snapdragon X65 modem and radio frequency system, as well as many other performance enhancements, are designed to provide an excellent 5G experience through faster cellular communication speed, wider network coverage and all-day battery life.
The Snapdragon X65 is the world’s first modem and radio frequency system to increase the 5G stand-alone air interface rate to 10Gbps. The current Sub-6GHz network can support air interface peak rates from 1Gbps to several Gbps. This shows the rate increase brought by the Snapdragon X65 Is very huge. If compared with the peak rate of the early LTE, the peak rate of the Snapdragon X65 is 100 times higher.
The Snapdragon X65 5G modem and radio frequency system includes a series of components, such as modems, millimeter wave modules, radio frequency transceivers and radio frequency front ends. Qualcomm also simultaneously launched a new generation of 5G radio frequency front end solutions.
The complete Qualcomm RF front-end product portfolio includes the 7th generation Qualcomm Broadband Envelope Tracker (Qualcomm QET7100), Qualcomm AI auxiliary signal enhancement technology, and a new integrated 5G/4G power amplifier module (Qualcomm QPM6679) and diversity module (Qualcomm QDM5579) ).
Among them, Qualcomm QET7100 is the world’s first broadband envelope tracking solution that supports multi-mode, multi-output, and multiple power amplifiers (PA), and supports global 5G Sub-6GHz and LTE frequency bands. Compared with the universal power tracking technology of competing products, Qualcomm QET7100 can increase energy efficiency by 30%.
Qualcomm AI auxiliary signal enhancement technology introduces AI-supported 5G adaptive antenna tuning solutions, which can adaptive antenna tuning to help terminal manufacturers cope with the increasing number of antennas and frequency ranges required for 5G mobile terminals. Qualcomm AI assisted signal enhancement technology uses AI training models to intelligently detect the position of the user’s hand holding the terminal, and dynamically tune the antenna in real time to provide a stable 5G network connection.
Compared with previous-generation solutions, AI-based detection increases the accuracy of contextual perception by 30%, resulting in faster data rates, wider network coverage, and longer battery life.
The new integrated 5G/4G power amplifier module (Qualcomm QPM6679) supports full 100MHz envelope tracking without external duplex filters, thereby improving energy efficiency and increasing transmission power, resulting in faster upload speeds and more reliable connections. In addition, the brand-new dual-frequency diversity module (Qualcomm QDM5579) occupies a relatively small footprint and is also the smallest in the current commercial modules. Thanks to their advanced integration, the above-mentioned new modules will greatly save board area and support terminal manufacturers to design mobile terminals with top-level appearance.
The tight integration of the Snapdragon X65 5G modem and radio frequency system, as well as advanced modem and radio frequency technology, will help terminal manufacturers bring consumers excellent data transmission rates, network coverage, call quality and all-day battery life through stylish terminals.
In addition to the Snapdragon X65, Qualcomm also launched the Snapdragon X62 5G modem and radio frequency system, which is a modem-to-antenna solution optimized for the mainstream mobile broadband application market.
Snapdragon X65 and Snapdragon X62 are currently sampling to customers. Commercial terminals based on these two modems and radio frequency solutions are expected to be available later in 2021.
Also unveiled alongside the Snapdragon X65 is Qualcomm’s second-generation 5G fixed wireless access (FWA) platform. The platform uses Qualcomm Snapdragon X65 5G modem and radio frequency system, and the second-generation Qualcomm QTM547 extended-range millimeter wave antenna module, supports extended-range high-power Sub-6GHz 5G connection, and the world’s first 5G Sub-6GHz 8-channel reception and support Qualcomm dynamic antenna tuning technology.
With its extended-range 5G millimeter wave, extended-range high-power Sub-6GHz 5G and Sub-6GHz 8-channel reception, the new platform will help increase network capacity, expand coverage, and provide an excellent user experience. It also helps to reduce the cost of laying dedicated fixed networks, which will promote smoother and faster 5G commercial use, and be able to provide multi-gigabit transmission speeds and low-latency 5G connections to a wider customer base within its coverage. .
For terminal manufacturers, the introduction of Qualcomm’s second-generation 5G fixed wireless access platform can also improve the performance of CPE, reduce development workload, and accelerate the release time of CPE equipment.
Qualcomm also launched a new Snapdragon X12+ LTE modem for fixed wireless access terminals that rely entirely on 4G networks. The Snapdragon X12+ modem enables terminal manufacturers and operators to upgrade fixed wireless access terminals through LTE solutions to achieve speeds of up to 600Mbps.
Commercial terminals using Qualcomm’s second-generation 5G fixed wireless access platform are expected to be available in the first half of 2022.
