Mold clamp tools definition

What is mold clamp? The mold clamp (also called mould clamp) is a kind of auxiliary clamping unit often used in injection mold processing, its main function is to keep the machined parts not shaking not moving in the processing.

Today, we talk about the wired and wireless IoT Communication Technologies, the simple 13 common communication technologies in IoT.

We have compiled and summarized the commonly used wired and wireless communication methods of IoT for future reference.

Communication frequency band: license-free frequency band. Use Industrial Scientific Medical (ISM) frequency band, 915MHz (U.S.), 868MHz (Europe), 2. 4GHz (Global)

NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth, and can be directly deployed on a GSM network, UMTS network, or LTE network.

Communication frequency band: ISM frequency band including 433MHz, 868MHz, 915MHz, etc.

Communication distance: 2-5 km for towns, 15 km for suburbs

From 12 perspectives on Narrowband IoT vs Lora technology to learn which IoT standard is more advantageous.

Rapid developments in machine learning and M2M communication standards are playing a key role.

Semtech's LoRa technology is a bit ahead of the curve in this area, but NB-IoT (narrowband IoT) is also rapidly gaining traction as a powerful LPWAN standard.

Lora and LoRaWAN are often used as synonyms, but they do not refer to the same thing.

NB-IoT works well in urban areas but has only mediocre performance in suburban and rural areas (where 4G signal is not available).

LoRaWAN does not rely on cellular data or Wi-Fi, so it can maintain relatively stable coverage in any region.

Note: Compared to the cost of constructing base stations for 4G-LTE, which is necessary for the introduction of NB-IoT, the cost of constructing base stations for LoRa is a fraction of that for 4G-LTE, and the low investment required gives LoRa a significant advantage.

Despite the hype of 5G NR, Wi-Fi and 5GNR together play an important role in corporate use cases such as remote patient care and smart manufacturing. How 5G Enhances WiFi in the industries?

5G new radio is a very new technology. In addition to faster speeds, when 5G is actually implemented.

The dramatic claim that New 5G will replace WiFi is unfounded to New Radio 5G? It doesn't work today.

Few industries are as affected by 5G as manufacturing. In the manufacturing industry, the advent of cellular technology could stimulate the next industrial revolution.

Most factories continue to operate on Wi-Fi networks, but the wave of smart factories based on 5G technology is beginning to emerge.

Today, we talk about something about NB-IoT which you may not know.

NB-IoT refers to Narrow Band - Internet of Things (IoT) technology, which focuses on the Low Power Wide Area (LPWA) Internet of Things (IoT) market and is an emerging technology that can be widely used around the world.

Huawei, as the domestic leader in developing NB-IoT technology, has also attracted considerable attention from the technology community.

Q: How are the frequency bands for NB-IoT divided by domestic and international operators?

A: Most operators worldwide use the 900MHz band to deploy NB-IoT, and some operators deploy in the 800MHz band.

China Unicom's NB-IoT is deployed in the 900MHz and 1800MHz bands, and currently, only 900MHz is available for trials.

NB-IoT and LoRa account for 83% share of LPWAN market, low-power satellite IoT becomes a game-breaker, In-depth analysis of low-power wide-area (LPWAN) market in 2021.

According to the monitoring of IoT Analytics, in the second quarter and the third quarter of many countries because of the epidemic quarantine, the number NB-IoT and LoRa of LPWAN-enabled device activation in 2020 still reached 450 million units, with a year-on-year growth rate of 62%, especially in the epidemic prevention and control and supply chain visualization play an important role in the rapid growth of IoT applications;

Today, we talk about the several major benefits of NFC smart homes. Guess what are the benefits of NFC smart homes?

For applications in the era of interconnected smart homes, NFC technology can increase the ease of use, safety, etc. of equipment, and can greatly change the lifestyle of our daily homes.

As a short-field communication technology, NFC has a very wide range of applications, such as mobile payment, channel inspection, automobiles, smart homes, industrial control, and so on. With the continuous evolution of smart home scenarios, a large part of NFC devices will appear in the living room in the future.

What is an RFID warehouse management system?

RFID warehouse management system is a combination of RFID technology and warehouse management system to provide enterprises with a new storage model, to meet the needs of enterprise automation, transparency, intelligent storage, RFID technology, and warehouse management system to achieve a seamless docking, maximize the value of RFID technology applications in warehousing.

After the read, you can get the latest 5G/NB-IoT/LTE-Cat1/LoRa/Bluetooth/WiFi and other IoT wireless technology trends.

Over this period, the new 5G will contribute US$2.1 trillion in annual net GDP. This forecast is dependent on the actual commercialization of 5G new radio, which is the most noteworthy aspect of 5G.

The future of live streaming applications will be more rapid with the support of 5GNR.

Some data indicates that in cellular IoT connections, 60% of IoT connections require the narrowband network to provide services, about 10% of high-speed services require 4G Cat 4 or above or 5G eMBB to provide services, while the remaining 30% of low and medium rate IoT requires LTE Cat 1 or eMTC network to provide services.

The 5G core network (5GC) is the brain of the 5G mobile communication network, which is responsible for managing and controlling the entire network.

The 5G core network is a collective name of many 5G NE equipment and is not specifically referred to as a network element device.

AMF (Access and Mobility Management Function Access and Mobility Management) supports a UE with different mobility management requirements. AMF can be classified as 4G MME.

Store and manage the permanent user ID (SUPI) of the 5G system;

AN (Access Network) is the access network, which can be a 3GPP access network (such as LTE, 5G-NR), or a Non-3GPP access network (such as common WiFi access).

Apple's first use of UWB is to provide positioning data. Location Supports Many applications in the fields of reality (AR), virtual reality (VR), games, equipment recovery, file sharing, and advertising beacons.

Development of UWB technology

With the growth of wireless communication demand in 1990, the advantages of ultra-wideband (UWB) become more obvious.

In 2002, Wi-Fi is still a relatively new technology. The 802.11b router was launched in 1999, the theoretical maximum speed of the 2.4 GHz band is 11 Mbit / s.

802.11A standard is also defined in 1999 and promised that the theoretical speed in the 5 GHz band is 54 Mbit / s, but due to its higher chip group cost, there is no attention in the consumer.

The 7.5 GHz bandwidth allocated between 3.1 GHz and 10.6 GHz is extremely valuable for wireless communication engineers.
