AP, that is, the wireless switch, is generally used by multiple wireless stations to route extended signal coverage. For example, on the second floor of the home, a Router is placed on the first floor, but the wireless signal is unstable on the second floor, so you can place the first floorTwo wireless routes, the route is connected to the first platform with network cables, and the computer on the second floor is wirelessly connected to the wireless network on the second floor, rather than the wireless network on the first floor.
AP is short for Wireless Access Point, Chinese name: wireless access point; AP mode is also the wireless access point mode. AP is equivalent to a bridge connecting a wired network and a wireless network, and its main role is to connect various wireless network clients together, and then connect the wireless network to the Ethernet (this is the original meaning of the Access Point name).
Wireless AP (A wireless access point is an access point to a wireless network, commonly known as a "hot spot."
C language not only has the characteristics of low-level language directly manipulating hardware, but also has the characteristics of high-level language and natural language and human thinking logic, C language program is easy to write, easy to detect errors, and very practical. (2) C language has rich data types and operators, and simple syntax structure. (3) C language is a structured programming language that provides complete program control statements.
Therefore, after mastering C language, further learning C can learn object-oriented language with a familiar syntax, so as to achieve the purpose of twice the result with half the effort. In order to explain the characteristics of the C language source program structure, first look at the following programs. These programs are from simple to difficult, showing the characteristics of the C language source program in the composition structure.
Familiar with Visual C 0 integrated development environment master the method of structured program design, have a good programming style master the simple data structure and algorithm in the program design and can read simple proceduresIn the VisualC 0 integrated environment, it can write simple C programs, and has basic error correction and debugging program capabilities.
Here are a few essential things to learn C: a development environment, such as turbo C 0, which once occupied more than half of the DOS era development programs. But now in the windows era, turbo C has no feeling, it is difficult to edit the program, and drag and drop, there is no automatic induction function of function variables, and it is inconvenient to query reference materials.
Wireless data terminal is also called wireless data transmission terminal, that is, the terminal module used to achieve wireless data transmission. The wireless data terminal is usually connected to the lower computer to achieve the purpose of wireless data transmission, and has the title of "mobile phone in the industrial field", because its transmission principle is basically the same as the data transmission of the mobile phone we usually use.
TD-LTE wireless data terminal is a wireless data transmission equipment based on TD-LTE technology. TD-LTE is a branch of the 3GPP Long Term Evolution technology, which is jointly developed by several telecommunications operators and is one of the world's leading 4G LTE technology standards. This technology not only inherits the advantages of TDD, but also introduces MIMO and OFDM, thus achieving significant improvement in system bandwidth, network delay, mobility and other aspects.
Wireless data transmission terminal is the terminal module used to achieve wireless data transmission, usually connected to the lower computer to achieve the purpose of wireless data transmission.There is the title of "mobile phone in the industrial field", because its transmission principle is basically the same as the data transmission of the mobile phone used by the user. Among them, the more typical equipment includes wireless data transmission, wireless router and other equipment to meet people's needs.
In the professional field of computers, the most simple understanding of the terminal is the user or user equipment, the general wireless data terminal refers to the wireless network card, the wireless network card can be inserted into a sim card, the use of sim card to achieve wireless Internet access equipment. Wireless network card Wireless network card is a terminal wireless network device, wireless LAN wireless coverage through wireless connectionA wireless terminal device connected to a network for Internet use.
USSD is unstructured supplementary data service, which is a new type of interactive data service based on GSM network. When you use the mobile phone keyboard to input some numbers or symbols that have been pre-determined by the network, such as *#, and then press the send key, you can send a command to the network, and the network will select the service you need according to the command. MMI code is the communication company, this function is to be openedTelephone call transfer.
The Unstructured Supplementary Service Data (USSD) is a new type of interactive data service based on the GSM network. When you use the keyboard of your mobile phone to input some numbers or symbols that the network has made in advance, such as *#, and then press the send key, you can send a command to the network, and the network will select the service you need according to your command.
USSD code, the unstructured supplementary data service, is a new typeInteractive data service based on GSM network. When you use the mobile phone keyboard to input some numbers or symbols that have been pre-determined by the network, and then press the send key, you can send a command to the network, and the network selects the required service according to the command.
. Click the gear in the upper right corner of the desktop and select "System Settings" 2. Click on "System" - "Software and Updates" 3. Click "Additional driver", this time the system will automatically network monitoring the machineAdditional drivers are available, including your wireless card driver. 4. System identification after finding the relevant driver. The user only needs to select the image and click "Apply changes", and the computer will enter the process of downloading and installing the driver. It can be used after installation.
My NIC is from Broadcom. Download the driver from http:// and then decompress it.
First, confirm the device model. Access PCI-IDs.ucw.cz /mods/PC/... through the device's PCI IDs, such as 10ec: c821. ,Find your wireless device as RTL8821CE. Next, make the necessary preparations. Run the command 'sudo dpkg --configure -a' to configure the system, then install Git to get the source code as' sudo apt install git ', and check the version to make sure the installation was successful.
