Recently, Qualcomm announced that its wholly-owned subsidiary Qualcomm Technologies, Inc. (QTI) has integrated new upgraded X12 LTE modems to the upcoming Qualcomm® SnapdragonTM 820 processor, providing leading 4G LTE for top mobile terminals and Wi-Fi technology. The new Snapdragon 820 processor will meet unprecedented ultra-fast connection and seamless service needs.
The new upgrade, the X12 LTE modem integrated into the Snapdragon 820 processor will bring:
LTE Advanced speed
Downlink support CAT 12 (maximum transfer speed of 600 Mbps)
Upstream support CAT 13 (maximum transfer speed of 150 Mbps)
One downlink LTE carrier supports 4x4 MIMO
Breakthrough connection support on non-authorized spectrum
2x2 MU-MIMO (802.11ac)
Multi-gigaBIT 802.11ad
LTE-U and LTE + Wi-Fi Link Aggregation (LWA)
Integrated service across different connection types
Use the next generation of LTE and Wi-Fi HD voice and video calls
Cross Wi-Fi, LTE, 3G and 2G call continuity
RF front end
Advanced closed loop antenna tuner
Support carrier aggregation QUALCOMM RF360TM front-end solution
Wi-Fi / LTE antenna sharing
This is the first public announcement that supports the mobile terminal processor that supports downlink LTE Cat 12 and upstream CAT 13, which has increased by 33% and 200% respectively from the previous generation of products. In addition, the X12 LTE modem is also launched as a separation chipset, and has successfully demonstrated the download peak speed of up to 600 Mbps by downlink three carrier polymerization and 256-QAM; achieved high Double carrier polymerization and 64-QAM 150 Mbps upload peak speed. The Snapdragon 820 processor is the first processor that has been publicly announced to support the LTE 4X4 Multiple Output (MIMO) technology, intended to be doubled. LTE carrier download throughput. In addition, it has the "Uplink Data Compression" (UDC) feature, which is currently unique to the minority LTE modem, which is intended to enhance the user experience of various applications including web loading acceleration. The Snapdragon 820 processor is also the first processor that has been publicly announced to integrate advanced closed-loop antenna tuning technology. When matching with the QFE2550 antenna tuner, it is possible to dynamically optimize RF performance under the actual network conditions, especially for top phones. Challenging metal industrial design. Advanced closed loop tuning design is designed to reduce call-off lines, improve cell edge throughput and further reduce power consumption.
In addition to the leading LTE feature, the Snapdragon 820 processor also passes the Qualcomm® ViveTM 802.11AC, which is equipped with Qualcomm® MU | EFX MU-MIMO technology, and the three-frequency (11ad) Wi-Fi with more Gigabit 802.11ad (11ad) Wi-Fi Technology, achieve excellent Wi-Fi performance and connection experience. By integrating 2x2 802.11ac (11ac) and MU-MIMO technology, the terminal can achieve up to 50% on the basis of 1x1 configuration. The peak rate of 2x2 80 MHz 11ac is up to 867 Mbps, and the peak rate of 11AD is up to 4.6 Gbps at the same time. In addition, 11AD has a maximum of 5 times the user throughput promotion in an approximation with 11AC. With dynamic switches between 11AD and 11AC, the terminal can achieve high performance connections in an energy-saving manner. The high bandwidth and speed provided by 11AC Wi-Fi, 11AD Wi-Fi and MU-MIMO can improve performance to a new level to improve overall service quality and enhance user experience, such as 4K video streams, point-to-point large files. Sharing, media query terminal use, wireless extension base connection, and hard disk backup, etc.
The Snapdragon 820 processor will adopt advanced fusion technology, including integration between LTE and Wi-Fi, and mandate spectra and non-authorized spectral integration:
Deploying LTE (LTE-U) on an unauthorized spectrum: The Snapdragon 820 processor is the first public release for mobile terminals to provide a complete LTE-U supported processor. When matched with the WTR3950, it can improve mobile network capacity and user throughput by aggregating licenses and unauthorized spectrum.
LTE and Wi-Fi Link Aggregation (LWA): LWA is another way to aggregate authorization and unauthorized spectrum, which is designed to expand the license LTE network with Wi-Fi infrastructure to expand the LTE network with a non-authorized spectrum capacity. Capacity.
Next generation Wi-Fi call: X12 LTE modem by using IP Multimedia subsystem (IMS), supports next-generation HD LTE Voice (Vilte) call service, and also supports calls between LTE and Wi-Fi continuous Sex. With the awareness of Qualcomm® ZerothTM, the X 12 LTE modem can monitor the Wi-Fi connection quality in real time to decide whether to switch between LTE and Wi-Fi.
Antenna Sharing: The new modem supports Numerical Antenna Sharing Mechanism between LTE and Wi-Fi, aims to help manufacturers make more easily design of advanced technology such as LTE-U, 4X4 LTE MIMO and Shuangliu Wi-Fi. At the same time, it is guaranteed to have an attractive design, and the performance of any technique is minimized.
The Snapdragon 820 processor continues the long tradition of QTI integrated industry leading modem function. It also supports LTE broadcast and dual SIM card LTE carrier aggregation terminals. The terminal equipped with the Snapdragon 820 processor is expected to be officially launched in the first half of 2016.
