What is a wireless network card receiver?

Question 1: Is the wireless network card the same as the wireless receiver? What's it all about? Strictly speaking, a wireless network card is different from a wireless receiver. The wireless receiver includes a wireless network card.

The so-called wireless receiver refers to the receiver that transmits signals by wireless means, such as wireless network card, Bluetooth receiver and RF receiver.

Wireless network card is a wireless receiver using wireless network transmission technology.

Wireless receiver is a data transmission mode. For example, a Bluetooth receiver can be used to use a Bluetooth headset, a Bluetooth keyboard and a mouse. For example, a 2.4g RF receiver can use a 2.4g wireless mouse.

Wireless network cards are used to connect wireless local area networks, also known as wifi. After connecting, you can surf the Internet wirelessly.

Note that wireless network cards and wireless network cards are two different things. Wireless network card is actually the sim card of mobile phone, which can connect 3G and 4G networks of mobile operators. The wireless network card is connected to the wifi LAN and can only be used in a small area.

Question 2: What is the difference between an external wireless network card and a wireless network receiver? In fact, they are all wireless network cards. An external wireless network card is an external device through a slot or a u *** interface, and so is the wireless network card receiver, except that the working rate of the wireless network card receiver will be higher than that of the general wireless network card, and the receiving distance will be further.

Question 3: What's the difference between a wireless network card and a wireless network receiver? Wifi signals are generally wireless signals sent by wireless routers or wireless network cards such as 360 degrees. Generally, wireless network cards can be used as receivers or reflectors, but the drivers used are different. The 360-degree signal needs to be turned on, and the wireless router can work by connecting the power supply and the network cable without connecting the computer. In addition, mobile phones and network set-top boxes can also be used as WIFI hotspots.

Question 4: What is the difference between a computer wireless network card and a wireless receiver? What is a wireless network card?

1. The so-called wireless network is a wireless local area network (WLAN) that uses radio waves as the information transmission medium. It is very similar to the wired network in use, but the biggest difference lies in the different transmission media. Using radio technology instead of network cable can be used as a backup of wired network.

2. There are three general standards:

IEEE 802. 1 1a: 5GHz band is used, and the transmission speed is 54Mbps, which is incompatible with 802.1/b.

IEEE 802. 1 1b: 2.4GHz band is used and the transmission speed is1/Mbps.

IEEE 802. 1 1g: using 2.4GHz band, transmission speed is 54Mbps, and it is backward compatible with 802.11b.

At present, the most commonly used standard is IEEE 802. 1 1b, but IEEE 802. 1 1g is more powerful than the next generation standard.

3. Only the wireless network card cannot connect to the wireless network, and there must be a wireless AP, which is equivalent to the hub of the wired network. Only in the area covered by wireless AP can appropriate settings be made to connect to the wireless network. Wireless Internet access depends on wireless network card, and of course wireless routing (wireless cat) is needed. The wireless network card is equivalent to the receiver, and the wireless routing (wireless cat) is equivalent to the transmitter. In fact, it is still necessary to connect the online cable to the wireless cat, and then convert the signal into a wireless signal, which is sent and received by the wireless network card. Generally, wireless routing can tow 2 ~ 4 wireless network cards, and the effect is better within 50 meters, but the communication quality is far from poor. Strictly speaking, this wireless solution is only a wireless network deployment, and the working environment must be next to the wired network. The price of a set ranges from 300 to 800.

The other is purely wireless and requires communication equipment, such as a satellite receiver or a mobile phone with Internet access. These things are connected to the computer through special data lines to receive signals from satellite or wireless network services, but the speed is not so good and the communication cost is extremely expensive. And satellite receivers and mobile phones are also very expensive, usually in

3000~5000, the advantage is that you can surf the Internet even in the barren hills (of course, you must have a computer). Both solutions can be used on notebooks and desktops. Of course, the desktop is not convenient to move, and wireless is of little significance.

What is the difference between a wireless network card and a wireless network card? Although there is only one word difference between them, they are two concepts. Bring convenience to users with different Internet needs.

It is said that when the laptop could realize the wireless Internet access function, someone once put a mobile phone with infrared data association next to the laptop, wondering why the laptop and mobile phone still could not realize the wireless Internet access function. Although this is a joke, even today, there are still many people who don't know how to surf the Internet wirelessly with laptops.

However, with the increasing popularity of wireless Internet access technology, the era of "wireless Internet access" has quietly come to us. People are eager to break through the shackles of network cables, and the demand for free internet access anytime and anywhere has contributed to the growth of the wireless network card market. Now, whether there is wireless internet access has become one of the main indicators for consumers to measure whether a computer is high-grade. But in fact, many people know nothing about wireless network cards and wireless network cards, and they don't know why. Although there is only one word difference between them, they are two concepts.

The function and function of wireless network card are the same as that of ordinary computer network card, which is used to connect local area network. It is just a signal transceiver. Only when you find the exit to the Internet can you connect to the Internet. All wireless network cards can only be limited to the range of deployed wireless LAN. If you want to realize the wireless internet access function beyond the coverage of wireless LAN, that is, through wireless WAN, the computer must have a wireless network card and be configured at the same time. The function of wireless network card is equivalent to cable modem, which is also commonly known as "cat". It can use the SIM card of the mobile phone to connect to the Internet anywhere with wireless phone signal coverage. From this comparison, we can see that although both of them can realize the function of wireless internet access, the ways and means to achieve it are quite different. Because the coverage area of mobile phone signal is much larger than the environment of wireless local area network, all wireless network cards greatly reduce the dependence on geographical aspects and are more convenient and applicable to the vast number of individual users. ...& gt& gt

Question 5: What is a wireless receiver? Wireless network receiver, also known as high-power wireless network card and wireless server. The network card with built-in Lei Ling 3070 chip kernel is connected to the USB interface of the computer, which can automatically search the nearby large-area wireless network, cooperate with hacker software to decrypt, and forcibly "enjoy" the "wireless network receiver" of the wireless network to realize free wireless Internet access.

Different from the commonly used Lei Ling 8 187L chip, the wireless network receiver often uses Lei Ling 3070 chip with low radiation and high sensitivity, which is expensive and equipped with password cracking software. In essence, it is the core equipment of wireless network card, which has strong network search ability and can freely access other people's wireless networks. As long as there is wired broadband nearby, there will basically be wireless networks.

Ordinary users' wireless network password setting is relatively simple, which can be cracked with one click in a few minutes. In general, wireless Internet users are not easily noticed by real users if they don't download with high traffic. In fact, legitimate broadband users can check whether anyone is surfing the Internet as long as they log on to the wireless router, and they can "kick off" each other by filtering and limiting MAC addresses.

8 187L chip and Lei Ling 3070 chip are commonly used in wireless network receivers. At present, 8 187L chips are the mainstream. Although its performance is not as good as that of Lei Ling 3070 chip in all aspects, it is very popular with cottage manufacturers because of its low cost.

Question 6: What is the difference between a wireless network card and a wireless signal receiver? (For the desktop! How can I put it? First of all, the following friend said there was a mistake.

I know you just want to connect wirelessly. Only one wireless router and one wireless network card are needed.

Slotted wireless network cards with USB sockets are popular now.

Slot wireless network card built-in, USB wireless network card external.

Second, the wireless network card is not a calling card. As for the calling card, it's called a wireless network card. Thirdly, wireless receiver and wireless network card can be regarded as a way of expression.

Question 7: Can the wireless network card be used as a wireless receiver? You mean whether the wireless 3g network card of Telecom can be used as the wifi network card of the computer, right?

Mainly depends on whether there is a wifi chip. Most of them don't have integrated WIFI chips. Generally, there are only 3G network chips, and your idea cannot be realized.

The speed of the wireless network card is ok, and it can also be used to deal with 8M. The price depends on the brand and specifications. It is less than 30 yuan, a few hundred yuan, 8 meters at home, and tens of yuan if it is not far from wireless routing.

Question 8: What is a wireless network receiver? Compared with wired router, wireless router is a network cable distributed to many people. It is equivalent to plugging the power plug into the power socket, and more plugs can be plugged in to use electricity at the same time, except that wired routing separates the network from the router to transmit wireless signals, and the computer receives them with a wireless network card. Its basic signal source is still a limited network.

As for the network receiver, it may refer to the wireless network card sold by China Mobile Unicom, which uses the wireless network to send signals from satellites or transmission towers.

If "wireless network receiver" refers to the network card of the mobile company, then the difference between wireless network receiver and wireless router is equivalent to the difference between mobile phone and cordless phone (mother phone).

Question 9: How to use the wireless network card receiver? Hello ~

I don't know whether you borrowed a wireless network card or a wireless network card.

If it is a wireless network card, a local connection icon will be added to the network connection after it is installed on the computer. Right-click the icon and select Search for Available Wireless Connections in the pop-up page. Connect when the wireless network of the accessory is searched. This network needs a router that provides wireless signals and can be connected, otherwise it can't get online.

If it is a wireless network card, it will automatically run the dialing program after plugging in the computer. After installing the program, directly open the dialer and dial the Internet. This network uses the operator's 2G/3G network or WIFI network.

USB3G wireless network card, plug it in, eject the driver, download it, install it on the desktop, then double-click the icon, wait for a signal, click Connect to show that the connection is successful, don't turn it off, minimize it, and then you can surf the Internet normally. I use 3G of Telecom myself, and the network card is Huawei's brand. I will apply for a package from the operator myself.

What is a wireless receiver? It is a device that receives wireless signals and data.

I hope I can help you ~

Question10: What is the use of a WiFi wireless network receiver? WiFi wireless network receiver refers to the wireless network card.

Wireless network card is a terminal wireless network device, which uses wireless signals for data transmission without wired connection. Its function is to receive wireless WiFi signals.

According to different interfaces, wireless network cards can be divided into several types:

1. Desktop wireless network card with PCI interface.

2. PCMCIA interface network card of notebook computer.

3.USB wireless network card can be used by both desktop users and notebook users as long as the driver is installed. It should be noted that only wireless network cards with USB2.0 interface can meet the requirements of 802. 1 1g or 802. 1 1g+.

4. MINI-PCI wireless network card widely used in notebook computers. MINI-PCI is a built-in wireless network card, which is used as a standard model by both Centrino and non-Centrino wireless network cards. Its advantage is that it takes up a PC card or USB slot, which eliminates the trouble of carrying a PC card or USB card with you at any time. The prices of these wireless network cards are not much different, and the performance/function are similar, so you can choose according to your needs.

The mainstream rates of wireless network cards are 54M, 108M, 150M, 300M and 450M. This performance has a lot to do with the environment.

54Mbps: its WLAN transmission speed is generally between 16-30Mbps, which translates into MB, that is, the transmission speed per second is about 2MB-4MB. If the median value is 3MB, it takes about 35 seconds to transfer a file of 100MB, and it takes at least 4 minutes to transfer a file of 1GB.

108Mbps: its WLAN transmission speed is generally between 24 and 24-50Mbps, which is converted into MB, that is, the transmission speed per second is about 3MB-6MB. If the median value is 4.5MB, it takes about 25 seconds to transfer a file of 100MB, and it takes at least 2.5 minutes to transfer a file of 1GB.
