Hi Mi Fans!
Here we are discussing about the Snapdragon X12 LTE modem with Snapdragon 636 in Redmi Note 5 Pro: Industry leading connectivity with LTE download speeds up to 600 Mbps and integrated 802.11ac Wi-Fi with MU-MIMO. This is the first publicly announced processor for use in mobile devices to support LTE Category 12 in the downlink and Category 13 in the uplink, providing up to 33 percent and 200 percent improvement over its predecessor’s download and upload speeds, respectively.
Faster, consistent connection

With LTE downlink speeds up to 2X faster, the Snapdragon X12 modem is engineered to quickly download a favorite TV show or an entire album worth of songs in more locations, with greater consistency.

New Upgraded X12 LTE Modem

The Snapdragon 636 available as a discrete chipset, the X12 LTE modem has demonstrated peak download speeds of up to 600 Mbps through 3x downlink carrier aggregation and 256-QAM, as well as peak upload speeds of up to 150 Mbps through 2X uplink carrier aggregation and 64-QAM. The Snapdragon 636 processor is also the first publicly announced processor to offer LTE support for 4x4 Multi-Input Multi-Output (MIMO), designed to double download throughput speeds on a single LTE carrier.
In addition, it features Uplink Data Compression (UDC), a feature that is currently unique to select Snapdragon LTE modems, and engineered to enhance the user experience in a wide range of applications, including accelerating web page loading times. The Snapdragon 636 processor is also the first publicly announced processor with Advanced Closed-Loop Antenna Tuning when paired with the QFE2550 Antenna Tuner, designed to dynamically optimize RF performance in real network conditions, particularly for challenging metallic industrial designs in premium tier handsets. Advanced Closed-Loop Antenna Tuning is designed to reduce dropped calls, improve cell-edge throughput and even lower power consumption.


In addition to its leading LTE features, the Snapdragon 636 processor also supports superior Wi-Fi performance and connectivity experiences through Qualcomm® VIVE™ 802.11ac with Qualcomm MU  | EFX MU-MIMO technology, along with tri-band support, through multi-gigabit 802.11ad (11ad) Wi-Fi. With 2x2 802.11ac (11ac) plus MU-MIMO technology, devices will have the ability to achieve a range increase of up to 50 percent over the 1x1 configuration.
The peak rate of 2x2 80 MHz 11ac is up to 867 Mbps, while the 11ad peak rate is up to 4.6 Gbps. Additionally, 11ad offers up to a five-time increase in user throughput with similar power consumption as 11ac. With dynamic session transfer between 11ad and 11ac, devices will have the ability to achieve high-performance connectivity in a power-efficient way. The high bandwidth and speeds offered by 11ac Wi-Fi, 11ad Wi-Fi, and MU-MIMO brings new levels of performance designed to improve the overall quality of service, and enhance user experiences for applications such as streaming 4K video, doing peer-to-peer large file sharing, using media kiosks, docking wirelessly, hard disk backups and more.
X12 LTE - Modem/WiFi

The Snapdragon 636 processor features advanced convergence technologies between LTE and Wi-Fi, and between licensed and unlicensed spectrum:
LTE-Unlicensed (LTE-U). The Snapdragon 636 processor is the first publicly announced processor for use in mobile devices to offer comprehensive LTE-U support when paired with the WTR3950, increasing mobile network capacity and user throughput by aggregating LTE in licensed and unlicensed bands.
LTE and Wi-Fi Link Aggregation (LWA). LWA is another method of aggregating licensed and unlicensed spectrum.
It is designed to allow mobile operators to utilize their Wi-Fi infrastructure to augment licensed LTE network capacity with unlicensed spectrum capacity.
Next-generation Wi-Fi calling. The X12 LTE modem supports next-generation HD Voice over LTE (VoLTE) and Video over LTE (ViLTE) calling services using the IP Multimedia Subsystem, with support for call continuity between LTE and Wi-Fi. Making use of the cognitive capabilities of Qualcomm®Zeroth™, the X12 LTE modem monitors real-time Wi-Fi quality to decide if and when to shift the call from LTE to Wi-Fi or back.

Antenna sharing. The new modem supports several antenna sharing schemes between LTE and Wi-Fi, designed to make it easier for manufacturers to design devices with advanced technologies like LTE-U, 4x4 LTE MIMO, and 2-stream Wi-Fi, with attractive form factors and minimal performance impact on either technology.
