This article mainly discusses the technical advantages of the wireless LAN Standard IEEE802.11g. Data Transmission Based on OFDM technology With the wide application of wireless LAN technology, users have higher and higher requirements on data transmission rates. However, in the indoor environment, the complex electromagnetic environment, the multi-pass effect, frequency selective fading, and other interference sources make it more difficult to achie

the fault will be lifted after the external line is repaired. ③ Allow communication, but the Internet is offline Generally, when a user connects a Modem to a telephone, the user may be able to use the telephone instead of accessing the Internet. At this time, the LINE light of the ADSL Modem is not on. Check the wiring position of the device carefully before troubleshooting. Note the following: The install

separates the high frequency from the current and transmits it to a computer or phone, to transfer information. On the basis of no re-wiring, this technology can carry data, voice, video, and other services on existing wires, that is, to achieve the integration of four networks. End users can connect to the Internet by plugging in the power plug. PLC uses the range of m to 30 m to transmit signals. During transmission, the user data is modulated using GMSK or

1 Multimedia service drives the development of OFDM technology Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier digital modulation technology whose research history dates back to the mid 1960s, although the concept of OFDM has existed for a long time, but until recently, with the development of multimedia business, It is recognized that it is

Fixed Wireless Access networks are still very mainstream access technologies. Many people may not know about fixed wireless access networks. It does not matter. After reading this article, you will certainly have a lot of GAINS. I hope this article will teach you more things, will have a comprehensive understanding of the application of the Fixed Wireless Access Network. I. advantageous applications of Fixed Wireless Access NetworksIn recent years, the demand for Internet access by communication

sharing, network security, and network management. The common feature of the two modes is that the existing network infrastructure is used. Their common disadvantage is that the bandwidth expansion capability is limited. 4) PLC access method Power Line Communication Technology (PLC) is a communication method that uses power lines to transmit data and voice signals. The technology is to load the high frequency of information contained in the current, and then transmit it using a wire. the

only 0.75 times times the normal downlink sub-frame when scheduling , so the amount of data transmitted is small. In general, when the upper and lower sub-frames are matched, special sub-frames are considered as downlink sub-frames. is shown in the TDD format, the seed frame up and down line ratio relationship. and Uppts because the time is too short, not for data transmission, can be used as a random access PRACH (remember the random access DCI Format 4?). Please look again at the article "LTE

full, but cannot access the wireless network. Fault Analysis: In this case, the network administrator may have set a MAC address filter for the Wireless AP, allowing only the specified MAC address to be connected to the wireless network, and rejecting unauthorized users, to ensure the security of the wireless network. Troubleshooting: You can contact the Administrator to tell him the MAC address of your wireless network card and ask him to add the MAC address to the list of MAC addresses allowe

Can contact with the management, the MAC address of your wireless card to tell him, ask him to add this MAC address to allow access to the MAC address list. 　　8. Wireless access to the home network for notebook computers for Internet sharing Failure phenomenon The home network uses "ADSL Modem + Broadband router" to achieve Internet sharing without the need for PPPoE dialing. The new notebook computer is not connected to the wireless network for

Remote access to the Notepad file and the current Network and Dial-up Connections configuration may be inconsistent if you change the communication device (for example: serial port or modem), make sure that you reconfigure network and Dial-up co

ADSL is the mainstream form of broadband Internet access. Next we will introduce some maintenance methods that often encounter faults when using ADSL for Internet access, hoping to help you.I. Why is the ADSL indicator normal? The most important indicator of ADSL is "ADSL. When there is no problem with the ADSL line, the light should be green.However, some users will also be disconnected when the "ADSL" indicator is normal, and restart the MODEM. This
