With the development of the mobile Internet and the advent of the big data era, mobile phones are not only the basic functions of calls, text messages, etc., and web browsing, social applications, shopping and other operations have become mainstream. Mobile phones have gradually become the main entrance of the Internet, and connectivity is one. Mobile phones are becoming more and more important, and the modem is the one that determines connectivity.
As a veteran manufacturer in the field of communications for more than 30 years, Qualcomm has been working hard to improve the communication experience of smartphones in various scenarios. The accumulated related research and development investment has reached 41 billion US dollars, its processors, modems and other 3G, 4G. Wireless technology has always been the industry's leading representative. Today, let's talk about the Snapdragon X12 LTE modem equipped with the star product Snapdragon 820.
When talking about modems, we usually care about the uplink and downlink speeds, whether the supported frequency bands are rich, etc. The strength of the Snapdragon X12 LTE modem is undoubted in this respect. The downlink supports LTE Cat.12, reaching 600Mbps, and the uplink supports LTE Cat. .13, reaching a rate of 150 Mbps, supporting all 3GPP organization-certified network bands and carrier aggregation between bands. What are the meanings of these parameters? What is the impact on the user experience? Below we will help you understand the Snapdragon X12 LTE modem in all aspects through the concept of “Jianlong Quantongâ€.
The so-called "Jianlong Quantong" is not limited to the rich support frequency band we understand, and is compatible with the three major domestic carrier networks. This is Qualcomm's definition of a "more comprehensive and advanced" full Netcom concept in more dimensions. Specifically, Qualcomm defines the concept of “Jianlong Quantong†from five dimensions: global global full-band, full dual-card, full 4G+, full voice and full Wi-Fi. Around these five dimensions, the Xiaolong X12 LTE modem has excellent features. Let's take a look at it.
Global full frequency band: one mobile phone can connect to the world
Normally, all Netcom can support six modules, but the support in the frequency band is not consistent. For example, China Unicom and Verizon are all operating LTE-FDD networks, but the operating frequency bands are different. This shows that many domestic Netcom mobile phones have appeared. Supported by the system, but it cannot be used in practice abroad. In addition to supporting all domestic frequency band networks, Snapdragon Netcom supports all 3GPP organization-certified network bands and carrier aggregation between network bands, so that a mobile phone can connect to the world.
The Xiaolong X12 LTE modem has obvious advantages in full Netcom. It not only supports rich in frequency band, but also better supports the strength of the signal, brings a better communication experience, and also supports TruSignal signal priority technology. This technology can improve the quality of the call, even when the signal is weak, it can give the mobile phone a priority and stable connection service, which not only reduces the drop rate of the call by up to 30%, but also increases the battery life and data transmission speed by at most 20 % and 50%. At present, this technology has also been applied on the Nubian Z11 and Samsung Galleria S7/S7 edge, providing stable signals anytime, anywhere.
Full double card: step into the full Netcom 3.0 era
Dual card dual standby is very popular in the domestic market and has gradually become the standard for mobile phones. However, dual-card dual-standby is not only simple to plug in dual-cards. The earlier dual-card dual-standby only supports telecom cards as the main card. Mobile Unicom can only stay in 2G networks as a secondary card. Later, it gradually developed into a dual-card blind plug, but when the primary card is a 4G network, the secondary card is still a 2G network. At present, the Xiaolong X12 LTE modem supports full dual-card. When the primary card stays at 4G, the secondary card can support Unicom 3G voice calls. The advantages brought about by this are obvious. Especially in some areas, China Unicom's 3G WCDMA network voice calls are of higher quality in some areas than GSM networks, and the calls are more stable and reliable.
Full 4G+: Carrier aggregation is fast
China's operators are now vigorously promoting 4G+ networks. Mobile, telecom and China Unicom have deployed corresponding equipment to support 4G+, especially China Mobile. The network at the base station is basically mature. 4G+ brings undoubtedly a more mobile mobile Internet experience. The core technology is carrier aggregation, which uses multiple frequency bands at the same time to increase the system transmission bandwidth. The Opteron X12 LTE modem supports up to Cat.12 (600Mbps download bandwidth) and Upstream Cat.13 (150Mbps upload bandwidth). To know that the current carrier's infrastructure is only supported to Cat.6. If the operator upgrades the 4G+ speed again within one or two years, users using the Opteron X12 LTE modem can update through the software without updating the hardware terminal. By enjoying the latest technological achievements, we can see that it is extremely technically forward-looking.
In addition, based on the carrier aggregation technology, the Opteron X12 LTE modem provides Upload+Super Upload technology, which achieves up to three times faster data upload speed in the carrier network. In this era of social networking, everyone has the enthusiasm to share, whether it is the sharing of massive photos or music, or uploading high-definition video or live broadcast, the demand for upstream traffic has surged, and through Upload+ super upload technology, the above actual Application scenarios can be easily accomplished.
Full voice: VoLTE helps HD calls
The most basic function of the mobile phone is still the voice call, and the Xiaolong X12 LTE modem is also working to improve the quality of voice calls. VoLTE has become the current point technology. We know that VoLTE, as its name implies, solves the problem of calling on the LTE network and solves the problem of the fall of the call network. With the gradual completion of infrastructure, major operators are now promoting the VoLTE service. For example, China Mobile will open SMS in the Beijing area where the signal has been covered. The VoLTE network can support wider voice calls. Bandwidth, thus effectively improving the voice quality of the call and reducing the call delay.
In addition to support for VoLTE, the Opteron X12 LTE modem also features Wi-Fi calling. It has been realized that the convergence of LTE and Wi-Fi is the trend. Take North American operators as an example. They are deploying Wi-Fi calls and VoLTE at the same time, and the Snapdragon X12 LTE modem can automatically be between the two according to the actual situation. Make a choice and achieve a seamless transition between the two.
Full Wi-Fi: Easy connection without waiting
The Wi-Fi frequency band is mainly divided into 2.4 GHz and 5 GHz. This dual-band Wi-Fi has been popularized at present. In addition to supporting the above frequencies, the Snapdragon X12 LTE modem also supports 802.11ad, which is the 60 GHz band. Wi-Fi. This technology can extend the bandwidth to an astonishing 7 Gbps. In other words, it can transfer files of nearly 1 GB per second. Such a fast connection speed can be applied to data exchange between devices and devices. Ultra HD 4K video transmission is only It takes a few seconds, and there is no longer any trouble with Waiting and Caton.
In addition, the Snapdragon X12 LTE modem also supports MU-MIMO, which is the abbreviation of “MulTI-User MulTIple-Input MulTIple- Outputâ€, which is a new standard for the Internet of Things era. As we all know, in the Internet of Things era, there will be more and more smart devices in the home to access the Internet. Following the current standards, many smart devices are connected to routers, but they cannot exchange data with each other, and resources between products will also appear. The phenomenon of hiding makes the network not used properly. With MU-MIMO non-congested Wi-Fi technology, various intelligent hardware can communicate effectively and avoid Wi-Fi congestion, thus making our lives smarter. In addition, in terms of WiFi, the Snapdragon modem also supports the fantasy of LTE and Wi-Fi, as well as the convergence of LTE and Wi-Fi (LWA, LTE Wi-Fi AggregaTIon).
Through the above explanation, everyone should have a certain understanding of the excellent characteristics of the Snapdragon X12 LTE modem. As an important part of the Snapdragon 820, it demonstrates Qualcomm's leading position in the wireless communication industry and further explains Qualcomm's connection technology form for the future. A kind of thinking and guidance for the wind vane. As consumers, they can experience faster internet speeds, clearer voices, and smoother experiences. These are all the efforts of the Xiaolong X12 LTE modem.
