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.

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;

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.
