What is wireless broadband

1. Wireless broadband is a technology that can connect personal computers, handheld devices and other terminals to each other wirelessly. It was invented by CSIRO, a research institute of the Australian government, in the 1990s. Wireless broadband is a brand of wireless network communication technology. Its components include basic service units, distribution systems, access points, extended service units and gateways. Its purpose is to improve the interoperability between wireless network products based on IEEE standards.

2. In 2010, wireless broadband was more commonly used in large cities. Although the quality of wireless communication transmitted by wireless broadband technology was not very good, the data security performance was slightly worse than Bluetooth, and the transmission quality needed to be improved, the transmission speed was very fast and met the needs of personal and social informatization.

3. The main advantage of wireless broadband is that it does not require wiring and is not restricted by wiring conditions. Therefore, it is very suitable for the needs of mobile office users. And because the transmission signal power is lower than the transmission power of the mobile phone, using wireless broadband to access the Internet is relatively safe and healthy.

What is Wireless Fiber Broadband

Fiber-optic broadband is to convert the data to be transmitted from electrical signals to optical signals for communication. An "optical modem" is installed at both ends of the optical fiber for signal conversion. The difference between fiber-optic broadband and ADSL access methods is that ADSL uses electrical signals for transmission, while fiber-optic broadband uses optical signals for transmission.

Optical fiber is the most ideal transmission medium among various transmission media in broadband networks. It has the characteristics of large transmission capacity, good transmission quality, low loss, long relay distance, etc. Optical fiber transmission uses wavelength division multiplexing, that is, the data of multiple users in a community are combined into high-speed signals using PON technology, and then modulated into optical signals of different wavelengths for transmission in one optical fiber.

The three system structures of fiber optic access network are FTTN, FTTC and FTTH. In the process of network development, each structure has its application advantages, and in the process of network evolution to full service, each structure is a key link. The benefit of FTTN is that it pushes fiber optic further into the user network.

Why can't I access the Internet via broadband?

Computers cannot be directly connected to broadband optical fiber. Broadband optical fiber first needs to be connected to an optical modem, which is a device that converts optical signals into digital signals. Then the network cable can be connected to the computer and it can be used normally. However, you also need to enter the broadband account and password in the computer to connect to the Internet.

Computer usage tips: 1. Open the Task Manager - first right-click the taskbar and click the "Task Manager" option in the pop-up menu. This will open the Task Manager, and then you can terminate certain processes in the manager.

Or press the "Ctrl Alt . Enter" key combination at the same time, and then use the mouse to select the "Task Manager" option.

2. The computer displays Automatic Repair and cannot start up - When the computer starts up, it displays the "Automatic Repair" prompt, and it also displays "Your computer did not start correctly". At this time, we click the "Advanced Options" button on the page, then click the "Troubleshoot" button, then click the "Startup Settings" button, and then click the "Restart" button.

3. Turn on energy saving mode - If you want to reduce the energy consumption of your computer, then on the power options page, we will adjust the power mode to "energy saving" mode, which can reduce the performance of the computer as much as possible, thereby reducing the energy consumption of the device.
