NB-IoT prospects
With the advent of smart cities and the era of big data, wireless communications will achieve universal connectivity, and it is expected that the number of global Internet of Things connections will be trillions of times in the future. At present, there has been a large number of physical and physical connections, but most of these connections are carried by short-distance communication technologies such as Bluetooth, Wi-Fi, and ZigBee, and are not mobile networks of operators. In order to meet the needs of different IoT services, according to the characteristics of IoT services and the characteristics of mobile communication networks, the global communications industry has reached a consensus on jointly forming a low-power, wide-area coverage (LPWA) IoT standard, and the NB-IoT standard emerges as the times require. And freeze the standard in June this year.
According to the GSMA forecast. In the next five years, the cellular Internet of Things will grow sevenfold. By 2020, there will be about 3 billion connections carried over the carrier's network (of which 2.1 billion are connected to LPWA applications), industrial, personal applications, smart homes, public Business and many other aspects.
China is currently the world's largest M2M market, with cellular M2M connections of approximately 100 million. By 2020, this number is expected to increase to 350 million. The LPWA technology will provide an additional 730 million connections, making the total number of connections more than 1 billion.
In the next few years, China's Internet of Things industry will continue to develop rapidly, with an average annual growth rate of about 30%. In 2014, China's Internet of Things industry market scale was 600 billion yuan, reaching 750 billion yuan in 2015 and over 2 trillion yuan by 2020.
Cell-based NB-IoT is an important branch of the Internet of Everything. NB-IoT is built on a cellular network and consumes only about 180KHz. It can be deployed directly on GSM networks, UMTS networks or LTE networks to reduce deployment costs and achieve smooth upgrades.
After the NB-IoT standard came out, it is of great significance to the development of the Internet of Things. The industry believes that the application ratio of NB-IoT to the entire Internet of Things will reach 70%. It will not only activate many stock markets, such as smart meter reading is expected to add about 50 million per year, and in emerging applications, such as smart parking, wearable market, outdoor sports, health testing, home control and other markets will increase NB- The IoT connection application will drive the development of the entire IoT market.
NB-IoT advantage
The four capabilities of NB-IoT technology itself:
Low power consumption: up to 10 years of battery life;
Wide coverage: 20dB enhancement compared to GSM;
Low cost: based on the chip 1-2$ after mass production, the module cost is only 5$;
Massive connectivity: 100k ConnecTIons/cell, has made NB-IoT the best technology for LPWA applications.
In addition, NB-IoT has the advantages of carrier-based network infrastructure upgrades, carrier-class reliability, high security, and global roaming, as opposed to IoT technology using non-license spectrum.
SMT Feeder types,
1. different smt machines with different smt feeders, but different model of the same brand machine can use the same feeder,like Panasonic Feeder.
2. Base on the size and types of components, smt feeder could be divided into three types : Tube feeder; Tray Feeder; Bulk Feeder.
Tape feeders with the different size such as 8mm, 16mm, 24mm, 32mm, 44mm, 56mm etc.
3. Base on the feeder condition, smt feeder also could be divided into four types: original new SMT feeder parts, used original SMT feeder parts, imitation/copy new SMT feeder parts, imitation/copy used SMT feeder parts,
Original feeder is made by original smt machine production manufacturers. Due to the large demand for smt feeder, currently there are many copy new feeders parts. Our feeders quality is also very great and looking forward to your cooperation!
