Comparison between LAN and ADSL Broadband Access methods

In terms of access network technology, ADSL is a transitional broadband technology, which requires further investment to achieve real broadband.

Fiber-optic Ethernet technology is mature and widely used. broadband access is in place in one step. No investment is required. It is the best choice for transmitting voice, video, and data, and the best solution for campus network and medical network.

First, from the access network technology, ADSL belongs to the broadband transition technology, and it still needs to be invested in realizing the real broadband. Fiber-optic Ethernet technology is mature and widely used. broadband access is in place in one step. No need to invest in it is the best choice for transmitting voice, video, and data, and the best solution for campus networks and medical networks.

Second: the use of transmission media telephone line transmission by distance restrictions, Netease dropped, optical fiber and five types of line transmission without distance restrictions, and better transmission quality!

Third, both the access and use fees are in monthly subscription mode, but the radio/TV Broadband Access Fee and information fee are relatively low.

Fourth: the rate from upstream users to the network) the rate of radio/TV clients using fiber-optic Ethernet is faster, and the theoretical value can reach 10 to 100 MB, while the maximum bandwidth used in adsl mode can only reach: 768 KB

Fifth: broadband access to radio and television: the emphasis is on the diversity of localized broadband content based on the advantages of radio and television program resources. The emphasis is on videos, including film and television, video news, FLASH, and MTV. The film is classic, the results are clear and coherent, with video news becoming more exclusive. There are also many broadband content such as games, stocks, and songs, all of which are free of charge. ADSL access: the video content is single, there is no video news, there are only movies and the content is outdated, the update is slow, the film and television effect is poor, the image is not clear and there is a pause ADSL access cannot fully reflect the Broadband Characteristics, the download rate is asymmetrical with the uplink rate. At the same time, the bandwidth is limited by the carrier's exit, and it is difficult to meet the bandwidth required by the real bandwidth location. Therefore, the video content is greatly reduced.
