When traffic jams occur, the car will automatically choose to drive without a block; the briefcase will remind the owner to forget what to bring; the clothes will "tell" the washing machine's requirements for color and water temperature... In the near future, such a scene It can become a reality through the Internet of Things. This is also the direction of the future development of information technology, so the Internet of Things is considered to be the third wave of the information industry.
The Internet of Things has entered the stage of hard work from concept hype, and some pioneering companies have emerged in the Internet of Vehicles and smart homes. The IoT sector has benefited from the support of national policies and is winning a historic opportunity to accelerate development. Although the Internet of Things industry has to really change from the current research and concept stage to concrete practicality, it may take at least 5-10 years, but now the Internet of Things has risen to the national strategic level, and the Nine-Five Plan has raised nine Fields: Intelligent industry, intelligent agriculture, intelligent logistics, intelligent transportation, smart grid, intelligent environmental protection, intelligent security, smart medical, smart home nine areas. They have one thing in common - they are all traditional industries. The Internet of Things makes traditional industries informatized, making traditional industries more automated and intelligent. Therefore, from the perspective of the government, the Internet of Things is more realistic and can drive the upgrading of traditional industries. And there are more opportunities for localization, so it is not difficult to understand the support repeatedly.
According to statistics released by ABI Research, the total number of wireless networking devices on the Internet of Things has exceeded 10 billion, and it expects this data to triple again to 2020 billion by 2020. Faced with such a huge market temptation, how can enterprises go more stable and farther in this wave of Internet of Things? Let's take a look at the interpretation of the leader Qualcomm and Silicon Labs.
Important considerations - communication standards
The Internet of Things refers to the "Internet connected with objects". Through certain technical means, it can connect any item with the Internet, exchange information and communicate, and realize intelligent identification, positioning, tracking, monitoring and management. According to professional predictions, if the Internet of Things is fully constituted, its industry is 30 times larger than the Internet. The Internet of Things will become the next trillion-dollar communication business. On the one hand, the Internet of Things can improve economic efficiency and save costs, and on the other hand, it can provide technical impetus for the recovery of the global economy. Once the Internet of Things is widely popularized, a large number of daily necessities need to be equipped with small and smart sensors, or directly upgraded, and the business opportunities brought to the market will be too large to estimate. The number of sensors and electronic tags and associated interface devices for animals and plants and machines and articles will greatly exceed the number of mobile phones.
However, the Internet of Things has the characteristics of network decentralization, variety of data types, and flexible application requirements. At this stage, many wireless technologies such as Bluetooth, WiFi, ZigBee, Cellular and RFID are driving the growth of intelligent networking equipment. Important factors, but the long-term development of this market depends on when wireless technology can become invisible. At that time, consumers only know that they use wireless technology to connect to the Internet, but do not know what technology they use. That is to say, there needs to be a unified framework to include the communication technologies in the field of Internet of Things, forming a synergy of development, so as to maximize the development of the industry.
The relevant person in charge of Silicon Labs interprets this. Silicon Labs always believes that a single wireless technology cannot meet the network requirements of all IoT applications. To develop cost-effective IoT products, engineers must choose the best wireless technology for their application. IoT should be based on a variety of different wireless protocols. For devices that need access to the Internet, they will need to support Internet Protocol (IP) in the transport channel. While Wi-Fi natively supports IP and works flawlessly on smartphones, tablets and PCs, it is too power hungry for battery-powered devices. For low-bandwidth applications that do not require direct user intervention, 2.4GHz ZigBee, Bluetooth Smart, and sub-GHz technologies provide low-power wireless connectivity that is easy to integrate into embedded systems. For simple applications (such as garage door keys) or systems that require long-distance connections (such as irrigation systems), sub-GHz radios are undoubtedly the optimal solution. If you need two-way communication, security, or connecting a large number of devices to a mesh network, ZigBee provides a more reliable wireless solution.
The relevant person in charge of Qualcomm said that there is no "one-size-fits-all" solution in the ecosystem of "Internet of Everything". Terminal types and usage examples vary widely, and there is currently no single standard that can be used universally. Qualcomm believes that the main obstacle to the full realization of the Internet of Everything is the lack of a unified framework that can always prioritize intelligent interoperability between different systems under any transport layer, platform, operating system or brand. The current "solutions" for connecting terminals are usually proprietary, creating isolated terminals and systems that are powerful but not interoperable.
Therefore, Qualcomm and dozens of other technology companies form the AllSeen Alliance, and are committed to widely supporting connectivity products based on the open, universal development framework of the AllJoyn open source project. With AllJoyn and its service framework to ensure interoperability and the AllSeen Alliance, the Internet of Everything is just around the corner. That's why AllJoyn uses the framework, not for specific operating systems, platforms or terminal types. It solves the toughest problem of identifying, configuring, and connecting different terminals within an adjacent peer-to-peer network, as well as interoperating between different brands of terminals and applications. Therefore, the terminal using AllJoyn can use any one of the communication protocols mentioned in the question as a bearer channel to implement a short-range connection with other AllJoyn-supported terminals.
The standardization development behind wireless technology is one of the main factors driving the continuous development of the Internet of Things. The two leaders have no objection to each other. They believe that the interoperability between different brands of operating systems, platforms and terminals has been different. The benign ecological environment formed by the industry sector is the basis for the rapid development of the Internet of Things.
Power consumption - the future of IOT products
Market research institutes predict that by 2020, the number of connected terminals is expected to exceed 25 billion. More than half of the terminals are terminals other than smartphones and tablets. The Internet of Things industry in 2020 will be the global economy. The added value of $1.9 trillion. This prospect is very broad, and the important factor in determining this prospect is low power consumption.
Low power consumption is very important for the Internet of Things. Ultra-low power cutting-edge technology is another major factor driving the continuous growth of the Internet of Things. For this reason, Qualcomm has a deep understanding and value of low power consumption. The Opteron processor is known for its superior functionality and performance, as well as its ultra-low power consumption. These features have also been extended to other chipsets in our portfolio, such as Qualcomm's latest generation of low-power Wi-Fi platforms - QCA4002 and QCA4004. These chipsets help users in the simplest way and at the lowest cost in a variety of terminals, large household appliances (such as washing machines, air conditioners, water heaters, etc.), consumer electronics, sensors, home lighting smart plugs, security and automation systems. Added Wi-Fi capabilities. These new platforms feature on-chip processors and memory, eliminating the need to add additional system controllers that increase product cost, complexity, and power consumption.
Silicon Labs believes that 2014 is the "year of IoT" and introduces the industry's most energy-efficient 32-bit MCU EFM32 Gecko series. The EFM32 Gecko MCU provides industry-leading energy efficiency in all energy modes, thus ensuring Long battery life, optimum processing performance, and a highly integrated small package size. The Gecko MCU's low-power sensor interface (LESENSE) and Peripheral Reflection System (PRS) are two attractive features for the ultra-low power budget of wearable devices. The LESENSE interface is capable of autonomously collecting and processing sensor data even when the MCU is in deep sleep mode, which allows the MCU to stay in low power mode for as long as possible while tracking sensor status and events. The PRS monitors complex system-level events and allows autonomous communication between different MCU peripherals while keeping the MCU in an energy-efficient sleep mode as much as possible, thereby reducing overall system power consumption.
In addition, Silicon Labs' Simplicity Studio development platform, equipped with real-time energy distribution curves and analysis tools to estimate energy consumption, balances device performance and energy efficiency, and balances device performance and power consumption to help Developers optimize the energy efficiency of IoT designs.
In the vast Internet of Things market, the fastest growing areas today include smart energy, connected homes, car networking, lighting control and security. We need to solve various difficulties and improve the industrial ecosystem in the process of advancement, in order to lay a firmer foundation for the development of the Internet of Things.
