If you know something about the Opteron processor that is currently installed in your flagship smartphone, you will know Qualcomm (Qualcomm), which provides strong technical support behind this processor.
Since the 2G and 3G eras, Qualcomm’s technology in the field of wireless communications has played a key role in the development of 2G/3G to 4G in recent years. Taking a chestnut, the CDMA technology that changed the communications industry and the lives of users, was implemented by Qualcomm for a long time.
The smart phone has become an indispensable device for people, but the performance of the mobile phone is not good. At present, it mainly relies on various test running software to measure, including various parameters such as CPU, GPU, camera, screen, etc. The test results are presented as an intuitive understanding. However, one of the most important indicators is often overlooked, which is the performance of the “mobile phone cat” modem. Although the mobile modem is small in size, it affects the connectivity between the mobile phone and the outside world. For example, if the call signal is good or not, whether the Internet is fast or not, LTE, Wi-Fi connection, etc. are inseparable from it. It can be said that it affects us. Every aspect of life.
Qualcomm has been in the field of communications for many years, and launched a variety of advanced LTE modems, bringing higher standards to the connectivity of smartphones and constantly refreshing the uplink and downlink rates. It must be said that at every point in time, the Qualcomm Snapdragon modem is the representative of the strongest communication capabilities at the time, even maintaining the rhythm of two or three generations of competitors.
Looking back at the evolution of the first generation of Qualcomm LTE LTE modems, we can see that Qualcomm has launched X5, X7, X8, X10, X12 and even X16 (up to the first generation of LTE multimode modems in 2010). 1Gbps download rate, Gigabit Gigabit Gigabit!) A variety of LTE modems.
After the launch of the Snapdragon 820 chip with X12 LTE modem this year, it not only brings higher uplink and downlink rates to smartphones, but also brings advanced connection experience such as VoLTE HD call, uplink and downlink carrier aggregation and 4×4 MIMO. Not long ago, the new flagship products such as Le Max 2, Xiaomi 5 and Nubia Z11, which were unveiled in front of the public, used many new functions of the Snapdragon 820.
