Recently, ARM announced the acquisition of two companies with rich experience in cellular communication standards, Mistbase and NextG-Com. Mitbase provides NB-IoT physical layer implementation, NextG-Com provides complete NB-IoT Layer 2 and Layer 3 software stack; the two teams are collaborating to launch integrated solutions, and ARM shows the key to becoming the NB-IoT market The IP supplier's intention is to help ARM camp partners accelerate the development of NB-IoT standard chips.
According to insiders, the two companies have been working with ARM for some time, so it is time to check the results of their products operating on the ARM architecture. Market research firm IHS Markit foresees that the deployment of NB-IoT technology in 2017 will be a reflex point in the LPWAN market.
Today's Internet of Things is also eager for a strong cellular IoT infrastructure network, and NB-IoT is undoubtedly the best choice for this basic network. Based on the application advantages of NB-IoT, it will bring the development of emerging markets of animal networking, including the stock market, bringing great commercial value to operators, including the value of connectivity, the value of data and the value of benefit sharing.
According to GSMA's forecast, the cellular Internet of Things will grow sevenfold in the next five years, and 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 and personal applications. , smart homes, public utilities and many other aspects.
2. NB-IoT requires the participation of the industry chain systemThe technological advantages of NB-IoT are transformed into market recognition, which requires the participation of the industry chain system, including international standards, operators, chips, software and IoT vertical applications.
Based on the advantages of NB-IoT standards and market application trends, it can be seen that the commercial conditions of NB-IoT are mature, and the entire industry chain will also be “a touch of the wayâ€. From operators, equipment vendors, chip manufacturers and terminal manufacturers, they are preparing for commercial use. ".
3. The addition of ARM has a major impact on the development of NB-IoT technology.The addition of ARM has increased the market competition and stimulated product price reduction, which can bring high-integration solutions to the NB-IoT chip market, reducing the design complexity and overall cost for IoT device developers.
Vacuum fluorescent display, referred to as VFD, is a low-energy electroluminescent display devices, the working principle and CRT similar. It has the incomparable advantage of liquid crystal display (LCD) in applications where there is a large variation in ambient brightness and no strict requirement for low power consumption, and is now widely used in audio-visual equipment, home electronics, automotive instruments, office equipment and instrumentation.
The structure of a VFD board is a typical vacuum triode structure, consisting of a cathode, a grid and an anode. In between the cathode and the anode there's a thin mesh of metal called the Grid that can be switched on or off, controlling the flow of electrons from the cathode to the anode. This VFD grid mesh is made of a thin metal plate with a thickness of 30 to 50μm, which is lithographed and made into a highly transparent fine lattice or tortoise-shaped metal mesh. When a positive voltage is applied to the grid, electrons emitted from the filament are accelerated and diffused toward the anode. When a negative voltage is applied to the grid, electron flow to the anode is cut off.
We custom VFD Grid with drawings provided by customers. The raw material we use for etched VFD Grid is SUS430 stainless steel. We are equipped with professional metal etching equipment and exposure development equipment. Our etched manufacturing capacity can achieve 0.05mm.
