The common wired and wireless communication technologies in IoT include RS-232, RS-485, USB, Z-Wave, IPv6, Wi-Fi, Bluetooth, Lora, NB-IoT, NFC, RF, GSM, 3G 4G, etc.
With the progress and development of the times, society gradually enters the Internet +, various sensors collect data more and more abundantly, big data applications follow, and people consider incorporating various devices directly into the Internet to facilitate data collection, management as well as analysis and calculation.
IoT intelligence is no longer limited to small devices and small network stages but has entered the complete field of intelligent industrialization. Intelligent IoTisation steps into maturity on big data, cloud computing, and virtual reality, and is incorporated into the whole big ecological environment of the Internet+.
The new 5G and massive MIMO are everywhere. What can the 5G massive MIMO bring to our life?
With the continuous progress of information technology, digitalization, and big data, the development of antenna technology also has higher requirements, and the communication system keeps developing to the higher frequency band and larger bandwidth.
Looking back to the radio communication technology, from the 1895 Italian scientist Marconi, the first wireless telegram is filled with the other side of the ocean. It has already passed more than 120 years in social life, aerospace, military, etc. Radio communications technology has played an irreplaceable role.

This frequency range for 430.050 ~ 434.790MHz, in the world range.
This frequency range is from 868 to 870 MHz, in the UHF band.
ISM Band Frequency 915 MHz
In the United States and Australia, the frequency range 888 to 889 MHz and 902 to 928 MHz has been available and used by the backscatter RFID system.
ISM Band Frequency 2.4 GHz
This ISM band frequency range is 2.400 ~ 2.483GHz, belongs to the microwave band.
ISM applications in this band include Bluetooth and 802.11 protocol wireless networks.
Microwave / Bluetooth / WIFI, etc. are used in this frequency, in addition to domestic RFID also uses this frequency.
ISM Band Frequency 5.8GHz
This ISM frequency range is 5.725 ~ 5.875GHz.
The cellular IoT is a method of connecting physical devices (sensors, etc.) to the Internet, and transmits physical devices (sensors, etc.) on the same mobile network as smartphones.
The cellular network connects IoT devices will exceed 20 billion in 2023. Specifically, the number of IoT devices connected via LTE and 5G exceeds 3.5 billion, mainly in China and Northeast Asia.
Two major forms of cellular Internet of Things: LTE-M and NB-IoT
In fact, all current cellular IoT applications use either LTE-M or NB-IoT or GSM cellular infrastructure.
While only the United States, the Netherlands, Ireland, and Australia cover national LTE, GSM has become the norm in many non-Western regions such as Eastern Europe and Africa.
What is narrowband internet of things technology? Why is the narrowband internet of things technology emerging?
What is narrowband internet of things technology?
NB-IoT refers to NarrowBand Internet of Things (Narrowband-IoT) technology. Different IoT services have different requirements for data transmission capability and real-time performance.
Depending on the transmission rate, IoT services can be differentiated into high, medium, and low speed:
High-speed IoT services:
Mainly using 3G and 4G technologies, such as in-vehicle IoT devices and surveillance cameras, the corresponding business features require real-time data transmission;
After reading, you will learn what is an IoT antenna, what are the IoT antenna types.
Internet of Things (IoT) devices need to have an antenna. The smaller the IoT device space, the more the frequency band and the more complex IoT antenna design. Internet of Things/IoT antenna includes NB-IoT antenna, 4G antenna, 5G antenna, GSM antenna, Lora antenna, GPRS antenna, UMTS antenna, Lora antenna, ISM antenna, GNSS antenna, WiFi antenna, GPS antenna, etc.
After the read, you will learn about what is NB-IoT, What are the features of NarrowBand-IoT, what are the NB-IoT applications.
NB-IoT (NarrowBand Internet of Things) is an emerging technology IoT based on the narrowband cellular things, support low-power device is connected to the cellular WAN data, is also known as a low-power wide-area network ( LPWA).
The GSM network, UMTS network, or an LTE network supporting short standby time, the network connection device requires a high connection efficiency.
Short-range transmission technology includes two categories based on Wi-Fi and Bluetooth, ZigBee.
In addition, wide area network technology includes cellular communication technology for high-power, high-rate, mainly used in GPS positioning technology is LoRa, Sixfox technology.
the 7 newest UWB industry trends to reveal how UWB technology future gFrom oes.
What is integrated positioning technology?
The integrated positioning technology integrates all positioning methods on the market, including GPS, base station positioning, Wi-Fi positioning, Bluetooth positioning, and sensor positioning, which can be described as integrated positioning technology sets.
There are many types of wireless communication technologies in the IoT, such as Wifi, Lora, NB-IoT, Bluetooth, ZigBee, Sigfox, etc.
What is wireless communication technology?
Wireless communication technology transmits information over the air using electromagnetic waves like IR (Infrared), RF (Radio Frequency), satellite, etc. For example, GPS, Wi-Fi, satellite television, wireless computer parts, wireless phones that include 3G and 4G networks, and Bluetooth.
Regarding the performance of active vs passive GPS antenna, both GPS passive antennas and active GPS antennas can receive GPS signals and achieve the satellite positioning function. But usually, the GPS active antenna is better than the passive GPS antenna, and the positioning speed active vs passive GPS antenna is faster.
From the antenna placement, GPS antenna can be divided into built-in antenna and external antenna; and GPS built-in antenna can be divided into the active and passive antenna.
As intelligent transport systems for smart cities begin to evolve, people can take advantages of intelligent transport systems for the many safety, efficiency, and cost benefits.
These new prospects are largely due to the expansion of IoT devices and 5G connectivity technologies.
In the process of injection molding, carelessness can cause injection molded product defects, how to prevent injection molded product defects?
If the diameter of the nozzle is too small, the specific volume of the material increases, and it is easy to cause cold, blocking the feed channel or consuming the injection pressure; in the cooling effect of the template hardened, thus preventing the smooth entry of molten material into the cavity.
For multi-cavity molds, the runner should be carefully arranged and the size of the sprue should be balanced, otherwise, only the cavities near the main flow path or the thick and short sprue can be filled, while the other cavities cannot be filled.
After read, you can learn about how to adjust the injection molding processes of temperature, pressure, and speed.
Injection molding temperature measurement and control are very important in injection moulding. Although these measurements are relatively simple, most injection molding machines do not have sufficient temperature tights or lines.
In order to counter the injection molding pressure, the locking mold pressure must be used, do not automatically select the maximum value available, and consider the projected area, calculate a suitable value.
This is the pressure that must be generated and transcended before the screw.
What are the key technical parameters of the injection molding machine? Here we introduce some of the technical parameters of the injection molding machine.
First, the technical parameters of the injection molding components
