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.
What is the ISM band and what are the main frequencies in the ISM band? After the read, you will get the answer.
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.

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.
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.
