Multi-mode LTE or Internet of Things is a major technology trend


Introduction: As you can see, while Verizon and AT&T were using eMTC in the United States, while domestic operators deployed one of the boots of the multi-mode communication group, we began to wonder, what is multi-mode Internet of Things? What is the connection trend of the Internet of Things? How to deploy the enterprise? The CNET article explains the connection technology of the Internet of Things.

During this year's CES Asia, China Mobile officially launched the NB-IoT/eMTC/GSM three-module communication module A9500; time jumped back to the end of May, China Mobile and Qualcomm and Mobike launched the first eMTC in China. The NB-IoT/GSM (LTE Cat M1/NB1 and E-GPRS) multi-mode field test - two things in common, are all using the Qualcomm MDM9206 LTE IoT modem. So we all saw that while Verizon and AT&T were using eMTC in the United States, while domestic operators deployed one of the boots of the multimode communication group, we began to wonder, what is multimode Internet of Things? What is the connection trend of the Internet of Things? How to deploy the enterprise? The CNET article explains the connection technology of the Internet of Things.

Quoting Shen Lei, senior director of product marketing at Qualcomm, the conclusion is: “The most mainstream connectivity technology for the Internet of Things is cellular technology (4G or LTE IoT), including eMTC and NB-IoT, which are complementary, overlapping and intertwined, and different. The users, but the two technologies to a large extent improve the entire industry chain and various application services are predictable."

Connections and calculations, catalysts for the Internet of Things

From the concept, the definition of the Internet of Things is extremely broad. Simply put, smart cities such as lighting, parking, and transportation can all be connected and effectively managed; to mobile health, including patient diagnosis, patient tracking, and various environmental monitoring; to smart homes, such as water meters, Automatic meter readings such as electricity meters and gas meters; security and intelligent control of buildings; control of industrial automation; tracking of retail businesses and assets; security monitoring of personal property, tracking of children's footprints... Internet of Things is like an intelligent gimmick. Each industry must be beaten.

In such a variety of complex scenarios, it is impossible to trigger all services through only one technology, one network, and one system. The flexibility of its technology depends on the communication capabilities and computational capabilities required for the actual situation.

It is precisely because of this that the main technologies that urge BioNET to network in the future are divided into two parts: one is connectivity and the other is computing.

The former is the connection of various objects, they "talk" each other, there are short-distance, medium-range and wide-area connection technology. The latter includes CPU, GPU, multimedia, graphics, sensors, positioning, etc. These computing technologies in mobile phones will be applied to the Internet of Things.

Talk about connections. 1, short-distance connection, you can use Bluetooth, NFC, ZigBee this one or two meters range of connection technology. If it is a local area network, enhanced Bluetooth, or ZigBee, Wi-Fi, can also be used in homes, offices, airports, and cafes. Of course, Wi-Fi also has various levels, data rates, and coverage. You can use 802.11ac, 802.11a/b/g/n, 802.11ax, 1x1, and 2x2. The highest level can use 802.11ad. 2. If it is a larger range, such as the connection of a wide area network, such as the application of a smart city, there is no doubt that it needs cellular network technology, that is, 2G, 3G, 4G, future 5G technologies, it is a wide-area coverage, global scope The most mature and widely deployed technology within.
