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

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

As a broadband network for implementing high-speed Internet, there are currently some practical access methods, such as ADSL, CATV, fiber + LAN Ethernet, and WiMAX wireless access networks, but today we will talk about power line online PLC) and compare it with ADSL to understand it. PLC is a new "last mile" SOLUTION Similar to other broadband access methods, PLC is essentially a solution for local telecom or network companies. The "last mile" Wan end

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

Asyuncrical Digital Subscriber Loop Asymmetric Digital user line loop (ADSL) is a member of the XDSL family and is hailed as "express on modern information highway" by Western countries ". Because of its high downlink speed, high frequency bandwidth, and excellent performance, it is favored by many users and has become another new and faster and more efficient access method after modem and ISDN, it is also the most widely used access method in China.

Voice at command reference Note:Some modem do not have the voice communication function. The following table lists the voice AT commands that your modem can understand, including the Sound Amplifier command and the Tam command. Each Command description includes the command name, explanation, and related parameters. Remember:Your modem must be in Microsoft Windo

Broadband is undoubtedly one of the network standards that people are pursuing. When dial-up surfing is adopted and broadband is gradually popularized, we can predict the development of today's wireless networks, wireless Broadband Access technology will eventually become the most popular wireless network technology. Broadband Wireless Access is favored by the industry for its fast and flexible networking and easy upgrade. However, there are still many problems such as the establishment of pract

Hardware The connector is loose, the network cable is disconnected, the hub is damaged, and the computer system is faulty. For the above faults, you can observe the Modem, Hub, or computer indicators to help locate and replace suspected devices. Voltage is not normal, temperature is too high, lightning strikes-the voltage is not stable, it is best to configure the Modem with a small power UPS uninterruptibl

With the rapid development of wireless technologies such as Wi-Fi, WiMAX, and 3G, technology convergence has become an important means for equipment manufacturers to get rid of the predicament. Several methods of Technology Integration Wi-Fi, WiMAX, and 3G technologies have their own advantages. However, through analysis, we can see that if one of the three technologies has its own shor

Fixed wireless access technology mainly include: 3.5GHz wireless Access (MMDS), Local multicast distribution service (LMDS), 802.16d, mobile wireless access technology mainly includes: based on 802.15 Wpan, WLAN based on 802.11, WiMAX based on 802.16e , based on the 802.20 Wwan. According to the bandwidth, it can be divided into narrowband wireless access and broadband wireless access. The broadband wireless acces

Mobile communications in the world's great success, driving the development of a variety of broadband wireless technology, the world's wireless technology is stepping into the broadband universe. At present, 3G technology has been able to achieve mature business, WiMAX has become a new hotspot, other short-range broadband wireless technology is also emerging. 3G technology is basically mature Forward to high bandwidth and IP As a mobile network of

Although Mobile World Congress 2008 has just come to an end, the upcoming ctia wireless 2008 conference in the United States has become a focus of attention. In particular, the accidental absence of mobile phones including e71 and other eseries at the global mobile conference has made Nokia The performance at this exhibition is full of expectations. After not long ago revealed that e71 and other mobile phones are about to be released on ctia wireless 2008, the first time that Nokia's flagship E

In order to save Internet access fees and improve work efficiency, many people share the Internet with multiple computers by using the ADSL routing function. However, if you want to enjoy Internet access through ADSL, you also need to learn the proper adjustment of ADSL from the details. On-demand combination of hardware devices The "match" mentioned here refers to whether the ADSL Broadband modem works with a vswitch or a hub. Although both of them c
