Generally, there are three types of wireless LAN interfaces: 1. Built-in motherboard (no interface) 2. USB interface 3. PCMI slot type
Location: Inside a notebook, you can usually see it by opening the lid below.
Interface: Mini PCI-E: Types are subdivided into full-height cards and half-height cards. You must confirm before matching the card, otherwise there is only room for a half-height card and a full-height card will not fit in!
Interface Is Typically Used For Internal Wireless Networking Cards In Laptops
This can be seen only by disassembling the casing. It is troublesome, and the built-in wireless network card interface of the notebook is not uniform.
Specifically, you have to open the casing to find the wireless network card, then take a picture and search on the Internet Buy; personally suggest that if your built-in network card is broken, it is better to buy a wireless network card receiver with USB interface.
In general, there are four kinds of wireless network cards. Wireless network cards are mainly used in notebooks and Pads (handheld Laptops), and some are used in desktop Laptops. Therefore, the interfaces also have multiple specifications.
Common interfaces mainly include PCMCIA interface, USB interface, EXPRESS34 interface, EXPRESS54 interface, CF interface, etc.
Such as PCI interface wireless network card for desktop Laptops, PCMICA, MINI-PCI interface wireless network card for notebook Laptops, and more convenient USB wireless network card.
PCMCIA interface This type of interface to wireless network card is generally dedicated to mobile devices such as notebooks. It is limited by the space of the notebook Laptop, and the size is far from as large as the PCI interface network card.
The PCMCIA bus is divided into two categories, one is 16-bit PCMCIA, and the other is 32-bit CardBus. CardBus is a new high-performance PC card bus interface standard for notebook Laptops, just like the PCI bus widely used in desktop Laptops.
Compared with the original PC card standard, this bus standard has the following advantages: First, 32-bit data transmission and 33MHz operation.
The maximum throughput of CardBus Fast Ethernet PC Card is close to 90 Mbps, while 16-bit Fast Ethernet PC Card can only reach 20-30 Mbps. Second, the bus is autonomous.
Make the PC card independent of the main CPU and directly exchange data with the Laptop memory, so that the CPU can handle other tasks. Third, 3.3V power supply, low power consumption.
The battery life is improved, the heat dissipation inside the Laptop is reduced, and the reliability of the system is enhanced.
Fourth, it is backward compatible with 16-bit PC cards. PC cards of old Ethernet and Modem devices can still be used in the CardBus slot.
USB interface USB (Universal Serial Bus, universal serial bus interface) because its transmission rate is far greater than the traditional parallel port and serial port, the device is simple to install and supports hot swap.
Once the USB device is connected, it can be immediately recognized by the Laptop, and any required drivers can be loaded, and it can be used immediately without restarting the system.
When a device is no longer needed, it can be unplugged at any time, and another new device can be plugged into the port. Then, the new device can also be confirmed immediately and start working immediately, so more and more Loved by manufacturers and users.
CF interface CF (Compact Flash) wireless network card is mainly used in PDA and other devices. CF card is manufactured in accordance with ATA standard, but its interface is 50-pin instead of 68-pin, divided into two rows, each with 25 pins.
CF cards are divided into two categories: Type I and Type II. The specifications and characteristics of the two are basically the same.
The only difference between the two models is the thickness of the card. The CF card is not a pin interface like a hard disk but a 50-pin (1.27 mm) female interface, so it is not easy to be damaged. This design is similar to the PCMCIA interface.
SD interface As for products with SD interface or Express card interface, we suggest you not to consider it for now. The SD interface wireless network card requires the device to have an SDIO interface, which is only supported by a few PDAs, and it is expensive. As for the Express card interface, although its long-term trend to replace the PCMCIA interface is undoubted, at least it seems too advanced at this stage.
The interface type is different, mainly divided into three types, namely PCMCIA wireless network card, PCI wireless network card and USB wireless network card.
PCMCIA wireless network card is only suitable for notebook Laptops, supports hot plugging, and can easily realize mobile wireless access.
The PCI interface wireless network card is suitable for ordinary desktop Laptops. In fact, the PCI interface wireless network card is just an ordinary PC card inserted into the PCI adapter card.
The USB interface wireless network card is suitable for notebook Laptops and desktop Laptops, and supports hot swap. However, , Because USB network cards are a burden for notebooks, USB network cards are usually used in desktop Laptops.
There are several interfaces for the built-in wireless network card in the notebook-… Generally there are three types of wireless LAN interfaces: 1. Built-in motherboard (no interface) 2. USB interface 3. PCMI slot type
What kind of interface does the laptop’s built-in wireless network card have? … Basically, you have said that the interface of the built-in wireless network card in the notebook is the earliest. The card is directly installed in the PCI slot of the notebook. Now the wireless network card is sold on the market.
Notebooks all use this interface, the price is cheap, but the installation is more troublesome, you have to take the notebook apart. The MiniCard is connected to the PCMCIA interface, which is divided into…
What kinds of interfaces are there for the built-in wireless network card?? …… For desktop Laptops, it is divided into: PCI interface and USB interface; for notebooks: PCMICA interface, USB interface, MINI PCI interface
There are several interface types and advantages and disadvantages of the built-in wireless network card in the notebook? ……
The interface is the same, the card used inside is actually a mobile phone card, there are mobile, Unicom, etc., relatively speaking, CDMA is relatively cheap, and the network speed is still fast
What lines are connected to the two interfaces main and aux of the built-in wireless network card of the notebook?-…… The wiring of the two interfaces main and aux of the built-in wireless network card of the notebook are as follows: 1.
Main is the main antenna, generally gray, and aux is the auxiliary antenna. Generally black; 2. Most Intel wireless network card motherboards only have numbers 1, 2, 3, where the main number identified is 1 (connected with gray line), aux number is 2 (connected with black line), if there are 3,…
There are several built-in wireless network card interfaces in the notebook?-…… Nothing to say, if there is a pcim port in the notebook, buy the built-in card. There is also a mini, and it is estimated that your notebook is not that high-end.
If there is no external device, there is a USB Choice, good domestic Huawei has a lot of miscellaneous brands, and there are many foreign fakes. I took a look at my home in Harbin, and the quality is not good. Only Huawei’s can be seen, but more than 500, which is too expensive.
What kind of interface does the wireless network card device of the notebook Laptop have? …… Now all use USB. It is easy to save heat directly. The built-in 68PIN is not recommended. The speed is very slow.
Are the interfaces of the built-in wireless network card in the notebook the same? Can different models of notebooks work together? … The original interface is divided into MINI-PCI interface and PCI-E interface. A50 is a PCI interface, and 420 is a PCI-E interface. Two It happens to be asymmetric, so it can’t be used mutually.
There are several specifications for the built-in wireless network card in the notebook? …… There are three ways for the LAN card: 1. The wireless LAN card with USB interface is used by many people. 2. PCI expansion card is about ￥160.
Many people use it. 3. Built-in wireless module, about ￥160, because the installation is more troublesome, many sellers are unwilling to sell, so fewer people use it, and unprofessional people generally don’t know it.
Wide area network card CDMA or GPRSPCI expansion card, ￥250-1000 , pricing according to quality! The USB interface is about ￥400, only a relatively small brand makes it, so the price is relatively cheap,
