Speed outside | 5G Let's talk about the Internet of Things

When it comes to 5G networks, the fastest time comes to mind is the faster speed. This is categorized as eMBB in the three major application scenarios. With a large bandwidth, it not only brings about a peak speed increase, but also gives users access to densely populated areas. Bring a better web experience. Many times we don't feel the 4G network is actually upgrading compared to the past. It is because we use mobile networks mostly in densely populated areas. With limited network resources, it is difficult to meet our requirements for use. In the 5G phase, this problem is much easier to manage. After all, the cake is big, and people are not even more stretched.

In addition to eMBB, 5G also has two application scenarios of mMTC (massive internet of things) and uRLLC (low latency, highly reliable communication), or two kinds of features that can be provided. Today we mainly talk about things related to the Internet of Things. The mMTC network, as its name suggests, can guarantee the connection of 1 million devices/km2, which is a terrible and not excessive amount of data. The terror lies in its order of magnitude. Taking into account the future of the Internet of Everything, this figure can be more than just talk about it. Not so much because the network requirements of each individual IoT device are not high, and most of them can tolerate lower data transmission speeds and slower speeds.

It is not hard to imagine that smart hardware with particularly high network requirements is required, and it usually appears in indoor and other network environments where relatively good conditions exist. If necessary, they can use Wi-Fi and other network forms to complete their tasks. The larger mission of the IoT device is to form a part of the Internet of Things, such as the trash cans and water meters in smart cities. They need the network to transmit their own data and receive some simple commands, but the main operations are also It is limited to this. For example, the trash can tell the cleanup of the garbage in a certain area of the vehicle that it is fully loaded, and it urgently needs a wave of cleanup. For example, when the water fee is collected, the water meter can directly upload the water consumption information and save the students who are responsible for copying the water meter. We must also go from house to house to inspect the water meter. The network rate requirement for these operations is not high, and the basic problem after the mass connection is not significant.

In order to get a clear understanding of the current state of the Internet of Things scenario, we also need to understand the two nicknames of NB-IoT and eMTC, because mMTC itself is part of the 5G standard that is being discussed at a later stage. These two little guys go through If the evolution is strong enough to meet the 5G target well, it is very likely that it will be included as part of the standard or even directly adopted as a standard plan. Therefore, it can be said that this is a baby with two potentials.

Both NB-IoT and eMTC belong to the narrowband LTE technology. Here, broadband and narrowband refer to the bandwidth size. Bandwidths less than 4M are now collectively referred to as narrowband. As mentioned before, most IoT devices require low network speeds and have good coverage requirements. Therefore, they all tend to use lower frequency band networks, which have large wavelengths of low-frequency electromagnetic waves, good diffraction effects, and are more conducive to signal transmission in special environments such as through-wall and rainy weather.

The bandwidth used by NB-IoT is approximately 180KHz. It supports small-capacity data transmission at a rate of 100Kbps. It can be deployed directly on GSM, UMTS, and LTE networks. As for subsequent 5G networks, it is foreseeable to support them from the perspective of compatibility. , Helps reduce deployment costs, and facilitates promotion.

The eMTC uses about 1.4MHz bandwidth, and the maximum data transmission rate reaches 1Mbps. This is basically the upper limit of the network speed required by the Internet of Things, because 3GPP defined the minimum connection rate standard UE Cat-1 in R11, and its uplink rate is 5Mbps, downlink speed and 10Mbps, and after more in-depth discussion, taking into account more aspects of power consumption, it introduced a lower-cost, low-power Cat-0 at R12, and its upstream and downstream rate positioning 1Mbps, which proves that this is a commonly agreed specification after research.

Because the use of the same face - everything connected to the Internet, both in terms of characteristics have many common places, such as previously mentioned by the signal characteristics of the strong connectivity, NB-IoT signal transmission capacity in the same conditions It can improve 20dB more than Cat.4 LTE (the same scenario data of eMTC is 15dB) and can double the number of device connections supported by the existing wireless connection technology. Moreover, both connections are based on it. The deployed network itself has communication network-level connection security and reliability, and can guarantee the good operation of the Internet of Things network it hosts.

There are naturally differences in the similarities. In terms of power consumption, the lower rate of NB-IoT will be even more dominant. Eating a meal that can last for several years is a lovely workforce. It is very suitable. The establishment of large-scale Internet of Things systems. While the eMTC will consume slightly higher power consumption, the stronger network has features such as faster speed, lower latency, stronger positioning capability, and more suitable application scenarios.

In terms of actual layout, the North American market focuses on eMTC and assists in the development of NB-IoT. Because eMTC can be said to be the best of its 4G network advantages, the network itself, which is mainly concentrated on low frequencies, is more likely to facilitate eMTC commercialization. In Europe and most of Asia, including China, because the main frequency band of its own 4G network is concentrated on high frequencies, the first choice is more suitable for NB-IoT with network evolution. Of course, advanced technologies are certainly not missing. eMTC we also vigorously promote. Here NB-IoT good compatibility is mainly due to its predecessor NB-CIoT and NB-LTE technology, which NB-LTE part is itself raised by Ericsson, Nokia and other vendors, from the beginning The integration with LTE reduces the difficulty of deployment. As for the other part, NB-CIoT is a new technology jointly proposed by Qualcomm, Neull, and Huawei. It can build an IoT network that meets the target with ultra-low cost and other advantages. There are also a series of past and present lives. Here we only have to understand, and we do not go too far. We can simply understand that after the discussion on the "dug" of the 3GPP organization, Public house expertise NB-IoT responsible for future guiding light.

Here, the basic situation of the Internet of Things is now clearly understood. Although there are many other technologies coexisting, it is dominated by the NB-IoT and eMTC in the macro environment, especially the three major operators in China. The big advantage is that NB-IoT takes a half-step first, but eMTC is also the main development project. This situation is embarrassing. After all, although both network models are good, equipment manufacturers must always make choices. Xiao Bian tells you that they really don’t need to choose because Qualcomm is anxious and they want to find a good solution for them early on. Both networks want to use it. Then I’ll give you support for multiple models. Well, this is exactly the same as the current choices of all Netcom mobile phone users. Referring to the current China Netcom Qualcomm model, you probably know the advantages of Qualcomm in the Internet of Things.

In November 2016, Qualcomm launched China's first Cat-M1 test in conjunction with China Mobile and Ericsson. In December of the same year, Qualcomm completed the data transmission based on the Cat-M1 standard. It is said that some of the students in the network test may not understand Its significance, then we say something easy to understand. As early as last May, Qualcomm announced plans to cooperate with the China Mobile Research Institute and Mobike, China Mobile will needless to say, Mobba’s position in sharing bicycles. It is also a leading company, and because it is willing to invest more in building bicycles, its bicycles are smart locks that are used from the beginning, so it is not appropriate to explore IoT devices for cooperation.

As for the specific content of the cooperation, the three parties launched China's first eMTC/NB-IoT/GSM multi-mode outfield test. This test plan makes full use of China Mobile’s 2G/4G multimode network and puts Qualcomm’s MDM9206 for IoT applications worldwide. The multi-mode LTE IoT modem is applied to the Mobike's smart car lock to enhance the positioning of the Mobike bicycle and the real-time monitoring of the bicycle status and management performance.

From here, we can also see that in the future of the 5G Internet of Things, which seems to be within reach, multi-mode support will be a top priority, and Qualcomm has already achieved excellent performance in this area.

And during the just-concluded MWC, Qualcomm also released a new SDK for the MDM9206 that can help manufacturers, application developers, and even traditional industry companies unfamiliar with the Internet of Things field to develop IoT applications more easily and simply. Qualcomm also introduced a solution called Wireless Edge Services to meet the needs of new corporate customers and industrial IoT configurations, connect IoT devices, and manage these devices over a long period of time.

It can be said that in terms of the production of IoT devices and the deployment of the Internet of Things, Qualcomm has already come to the front. To be honest, the leader is born, and it is easier for the following sheep to follow. We also hope that the Internet of Things is truly interconnected. The future world can come to us as quickly as possible under the strong push of Qualcomm and other companies.

When it comes to 5G networks, the first thing that comes to mind is faster speed. This is categorized as eMBB (Enhanced Mobile Broadband) in the three major application scenarios.

Many times we don't feel the 4G network is actually improving compared to the past. It is because we use mobile networks mostly in densely populated areas. With joint efforts, it is difficult to meet the requirements of our use of limited network resources. In the 5G phase, this issue is much easier to manage.
