In fact, many people hope that the 2007 3G licences will be able to distribute digital trunking licences to some of the emerging operators, such as railcom, so that even if the 2008 Olympic Games cannot replace the digital trunking system in time, So can also make the domestic digital trunking communication standards can have more powerful support and European and American standards a high and low. VDSL2 Technical Features In recent years, with the

The development of networks is immeasurable. With the broadband access of ADSL, every household can access the Internet at high speed. Therefore, ADSL is constantly improved to achieve higher speed and wider bandwidth. Now let's take a look at the differences between ADSL2 and ADSL2 +. Due to frame structure improvement and optimized RS encoding, ADSL2 can reach

There are still many things worth learning about the ADSL2 access network. Here we will mainly introduce the ADSL2 access network technology and the future of application. Although the standards of ADSL2 and ADSL2 + have been formulated, the industry is still exploring these two ADSL upgrade technologies. In particular

From the ADSL2 + broadband pilot to a large-scale trial, more than half a year has encountered various faults. Frequent disconnection, slow Internet access, failure to open webpages, and other faults. On the surface, ADSL2 + is only a broadband access technology that improves the download speed. In fact, there is a certain gap between ADSL2 + and the first-genera

ADSL has become the main force for home broadband access. Currently, most users use the first-generation ADSL access technology. With the maturity of the second generation of ADSL access technology, ADSL2 + has begun to embark on a commercial journey. China Netcom and China Telecom have invested heavily in creating the ADSL2 + network to enrich the use of home broadband access to users. As a lucky person, I

Chengzhi Technology (Trendchip) Co., Ltd. announced today the release of a new generation of ADSL2 + chipset-tc1278 ADSL2 + personal terminal chip.The company's tc12008 ADSL2 + personal terminal chipset is designed to help achieve "Broadband home to thousands of homes" earlier ". Compared with traditional ADSL2 + termi

Recently, Texas Instrument (TI) announced that Aztech Systems, a global speech and data communication design and manufacturing company, will choose TI community Gateway (RG) solutions from its next-generation ADSL2 + gateway. The new Aztech product not only enriches its product series, but also enables it to provide broadband services at a low cost through the ADSL2 + network connection to achieve triple pl

Currently, ADSL2 + access technology is widely used. We believe that with the development of the communication industry, ADSL2 + access technology will be more comprehensive and stable, bringing users a good network environment. The ADSL2 + Access Technology and 4bandVDSL access method launched by Huawei have the following features: 1. Unified broadband access pl

This article analyzes the reasons why the ADSL2 standard has become a new favorite of the network. There are many problems with the ADSL2 standard on the network. For various ADSL2 standards, the following is a question and answer topic, hoping to cover all questions about the use of ADSL2 standards by netizens. Enhanc

Huawei's new adsl2+, 4bandVDSL access mode has the following characteristics: 1. Unified Broadband Access platform. In the original Dslam equipment directly to achieve the introduction of adsl2+, 4bandVDSL access mode, that is, in the original Smartaxdslam equipment and other business Board slot compatible interface Board, the original equipment can be based on user needs to achieve flexible configuration

device. It has other enterprise features not provided by the DG product line of NETGEAR, for example, 50 VPN tunnels for secure remote access, more powerful detachable 5dBi antennas, 2.4 GHz and 5.0 GHz (for specific regions) the band features 802.11a/g wireless technology, rugged blue metal chassis, SNMP-based monitoring and management, and a longer warranty period that gives customers peace of mind. DGFV338 is an ideal solution for companies that require a device that performs a variety of fu

Broadband Access Network is a frequently used access method. So I have studied the development and complementarity of broadband access networks. I would like to share with you here, hoping to help you. In recent years, with the rapid development of broadband Internet technology and broadband access network services, broadband access network users have gradually evolved from a single application of high-speed Internet access to comprehensive applications such as VoIP, IPTV, and visual communicati

DSL (digital user line) is a technology that converts the current twisted-pair telephone lines into access channels for multimedia and high-speed data communication. Connect the device to a twisted pair telephone line to generate three information

, on the other hand, VDSL technology has unparalleled advantages in bidirectional symmetry and high bandwidth within a short distance, so people may look forward to VDSL technology. It can be said that the choice of the two technologies is very contradictory. In the long run, Using DMT modulation is the only way to develop VDSL technology. The compatibility between VDSL2 and ADSL2 + gives the industry a cle

about 50% of DSL users is rarely up. That is to say, even in urban areas, it is impossible for all users to enjoy value-added services. Of course, it is impossible to increase the ARPU value for operators. In this case, you can move the DSLAM device down by using an external cabinet or FTTX + DSLAM to stay close to the user and eliminate the adverse effects of the line length, at the same time, it can also solve the problem of Broadband User outgoing rate that troubles operators. After DSLAM is

. In this case, you can move the DSLAM device down by using an external cabinet or FTTX + DSLAM to stay close to the user and eliminate the adverse effects of the line length, at the same time, it can also solve the problem of Broadband User outgoing rate that troubles operators. After DSLAM is moved down, DSLAM can be fully close to the user, so that a large access bandwidth can be provided based on a short access copper wire. In addition, when providing hd TV services for users, each channel r

three-band standard has defined either the QAM or DMT modulation methods, as a result, there has been a long debate over the two standards, facing the choice of the two modulation methods. The QAM method is simple and easy to develop, and the DMT method is more complex. Although with the development of ADSL2 + technology, many people have doubts about the application prospects of VDSL technology, on the other hand, VDSL technology has unparalleled ad

availability and sustainable development capability. The cost is relatively low, the scale effect is obvious. The network runs stably and is not affected by the objective environment. High safety performance, strong maintenance capability. The equipment has simple structure and less intermediate links. As can be seen from the above points, wired technology has more advantages than wireless technology, especially in terms of bandwidth delivery capabilities, so the mainstream of wired techno

There are many things worth learning about broadband access technology. Here we mainly introduce how to achieve bidirectional symmetric transmission speed of Mbps, which can be upgraded from ADSL, this section describes the use of broadband access technology to achieve stable transmission quality. Recently, NEC and NEC Magnus Communications announced that they will provide communication operators with the latest "AM3150R2" product of the "AM3100 series" Integrated

than 250 M away from the end user, with a target bandwidth of 500-1000 M per household. As you are closer to the user, you can get a relatively higher bandwidth, and G. fast will be used as a gigabit access solution comparable to FTTH. Unlike previous technologies, G. fast introduces user-defined concepts at the initial stage of standard design. Traditional copper wire access technologies, both ADSL2 and VDSL2
