What is the physical network card? If you figure out what things is that the card will naturally collapse. Things is to connect all things, to implement a network of technical things. Things NIC card is for use on an object, like a phone card, as the card is inserted into the hardware can be connected to the network, enabling real-time transmission of data.
Physical NIC two forms, i.e., welding the patch and the physical NIC physical NIC.
1. The physical connection pluggable card.
It is mainly divided into ordinary SIM card and network card industry cascade. It looks like we now use a SIM card. Ordinary SIM card is a card that we now use mobile phones, industrial-grade Things NICs exclusively for the Internet of Things devices. However, the quality of welding relatively strong function card can be used at very low or high temperature environment, in order to meet the different requirements of the external environment. Welding physics cards are widely used and cost effective in terms of cost, easy to install and use aspects.
2. The welded joints card.
Welding physical card is also called SMD things cards, each of which is often called MS card. MP addition to the advantages of the card, the MS card also has a small size, vibration resistance, high temperature, long life and other advantages. MS card has a high anti-vibration and requires higher cost, may be welded to the various smart devices.
3. The difference with the plug-welded physical NIC physical NIC.
The inserted card physical connection may be made from a common material in accordance with ordinary card chip and product grades, chips can also be made of special materials and special cards to meet specific environmental requirements, including injection molding and ceramics. NIC welding the materials used are different. Using SMD chip packaging technology, USIM card can be welded directly to the terminal equipment. The size of the patch is relatively small physical NIC, cooperation is also strong.
Normally, the card is only used for welding the front end of loading, and the plug things card can be used after loading. Welding small card, vibration, high temperature, long life often installed, smart metering front, wearable device. Plug-in card due to its physical connection and ease of installation and low cost has a broader range of applications.
Things welded and plug-in card have any advantage . Yuan medium shot of Things ( www.zjyiot.com ) said welding cards are usually customizable, so the card can not be used on the phone, and to adapt to a particular environment. It is generally used in industry. Pluggable more common physical network adapter, can be used on mobile phones, but the physical network card market is more complex, uneven quality and packaging. The purchaser must select and purchase reliable platform, such as physical coupler home.
