Introducing Snapdragon X65 and X62 – Qualcomm’s new generation of 5G modems
News unit EMGblog.com: from It has been more than four years since Snapdragon X50 was the first modem to equip smartphones with 5G technology. After this modem, Qualcomm released two other products named Snapdragon X55 and X60 launched on the market. On Tuesday, February 9 of this year (21 February 2019), this company announced the fourth generation of its 5G modems. unveiled. One of these products is called Snapdragon X65, and it is considered the first modem that offers a speed of 10 Gbps on paper in both independent (SA) and non-independent (NSA) 5th generation network structures. In fact, X65 is the successor of X60, the third modem of the fifth generation of Qualcomm, which was introduced in the last days of February 2020.
Qualcomm’s next product is called Snapdragon X62 and compared to X65, it is an affordable model. According to the manufacturer, both modems are the first products that support version 16 of the 3GPP standard (known as the second phase of 5G). In this way, it can be expected that the connection of multiple input and output (MIMO) and energy consumption will be improved in them. Also, Qualcomm has announced the upgradable architecture of these modems; This means that in the future, new 5G capabilities can be added to these two products with a software update and keep them updated for a longer period of time.
Among the changes of X65 compared to the previous generation, we can mention the increase in download speed from 7.5 Gb/s to 10 Gb/s. Of course, this figure is theoretically attainable, and the 5G network still cannot practically provide such an output. The Snapdragon X65 achieves this speed by combining 10 operators and an incredible 1,000 MHz bandwidth. The maximum download speed on X62 is 4.4 Gbps with a bandwidth of 400 MHz. It should be noted that this modem also supports millimeter waves and networks below 6 GHz.
According to Cristiano Amon, CEO-elect of Qualcomm, the company with Snapdragon modem radio frequency system The X65 has reached an important level of technological advancement, on which it can support connectivity up to 10 Gbps and the latest 5G capabilities. This success will play a vital role in realizing the use cases of 5G communication and will not only improve the user experience of high-end phones in an unprecedented way, but also open new doors to new fields of 5G expansion such as computing, extended reality, Internet of Things. It will open industrial, private fifth generation networks and fixed wireless access.
Qualcomm has introduced the QTM545 millimeter wave antenna module, which is the fourth generation of mmWave antennas. The size of this antenna has not changed compared to the previous generation, but it can not only transmit information with more power, but also supports all millimeter wave frequencies, including the n259 band (with a frequency of 41 Hz).
Antenna adjustment technology with The use of artificial intelligence is another technology that Qualcomm has unveiled with its new modems. This antenna can detect with 30% more accuracy how the user is holding the phone in his hand, thus helping to improve connectivity, increase data transfer speed, network coverage and battery life of the device. Also, another feature called Smart Transmit 2.0 has been considered in these two modems, which increases the upload speed and increases the coverage area of the antenna, and at the same time, it complies with the rules of radio frequency transmission.
Qualcomm has provided samples of X65 and X62 to manufacturing companies and hopes that the first products equipped with these new 5G modems will enter the market later this year. These modems will be present not only in smartphones but also in fixed modems.
Of course, the big question is whether there is currently a network that offers a speed of 10 Gbps? Currently, carriers such as Verizon, which provide high-speed 5G to users, have speeds of around 4 Gbps under ideal conditions. From the point of view of some experts, the speed of 10 gigabits will most likely not be experienced during the use of X65, and even though this chip is considered an important achievement, it will not remain a practical option for a long time.
