ADSL2 + transition or home network access terminator (1)

ADSL2 +, which claims to have significantly improved the quality of network transmission, has become a commercial express train. With IPTV officially launched in Shanghai, ADSL2 + is entering thousands of households at the fastest speed. China Telecom's network upgrading in 26 provinces is about to be fully completed. China Netcom is also actively preparing for the full upgrade of the ADSL2 + network, telecom operators are preparing to make ADSL2 + the terminator of home network access. The cost of fiber access is gradually decreasing, and the network transmission quality is significantly improved. Can ADSL2 + become the terminator of home network access?

ADSL2 + is actually created for IPTV

Internet applications such as video chat, on-demand video streaming, and IP phones have gradually entered common homes. networks that are inherently not rich in bandwidth are overwhelmed by these extremely bandwidth-consuming Internet applications, and network upgrades are imperative. Another contradiction lies in the presence of telecom operators. Urban Household broadband is becoming saturated, and the Rural Household broadband market is growing but has not entered a period of rapid development. In this case, the network is upgraded, the investment of telecom operators is too large and the risk is too high. Despite the relatively low cost of upgrading the ADSL2 + network, telecom operators are also in a dilemma when the home broadband access market is light and the cost of fiber access is low.

The launch of IPTV services has undoubtedly become an opportunity for telecom operators. Although IPTV services are operated by radio and television departments, the existing transmission networks of radio and television can only be transmitted in one way, which cannot meet the operation of IPTV networks. The networks of telecom operators meet the needs of IPTV service operation, it is also a logical task for radio and television to cooperate with telecom operators to operate IPTV services. Normal IPTV operation requires at least 2 Mbps of bandwidth for ADSL. at minimal cost, ADSL2 + is the best transmission channel for telecom operators to meet IPTV Business Operation requirements. With the large-scale commercialization of IPTV services, the ADSL2 + network upgrade is also in full swing.

The emergence of IPTV services undoubtedly gives telecom operators a strong confidence in network upgrade when they are struggling to upgrade their existing networks. LAN, ADSL2 +, and optical fiber access are three mainstream access modes. Only ADSL2 + is the most suitable for IPTV Business Operation, and the lowest upgrade cost. It is true that China Telecom is already moving towards the LAN and optical fiber access modes, but the popularization of these two access modes is still difficult, and telecom operators need to invest too much, and the network upgrade cycle is long, this is also the main reason why ADSL2 + has become a dedicated IPTV transmission channel.

For the current network access market, the fundamental purpose of the large-scale commercial use of ADSL2 + is to cater to the commercial use of IPTV services for radio and television. ADSL2 + is also a network tailored for IPTV. From the perspective of telecom operators, ADSL2 + is also the mainstream network access mode in the future.
