Nanjing Broadband Internet Nanjing Internet Access to Nanjing Computer Internet Application Computer wants to go online, start contacting each company to learn about the situation: China Telecom:
Contact number: 10000 Ask telecom, there are two ways, one is the optical cable is ADSL. The two service costs are exactly the same, but also must be a telephone. The difference is that there are optical cables in some places, and some local fibers are not paved. The cost is as follows:
Tel: 308
Telephone: Self-buy
Access fee: 58
Year: 1200 (send two months)
Month: 150
Bao hour: 20 yuan 10, 50 packs 30

Contact number: 10010 Unicom opened wire online:
First installed 180
Half year 600

Contact number: 10060 did not ask.
Nanjing Tietong:
Contact number: 10050 Ask if the phone is opened: 84070015 900 yuan a year, (another two months of online fee, or send another telephone plus three hundred dollars phone bills.)

The above companies will first ask which cell you are in. Because many places have not carried out service. I am not lucky, in addition to telecommunications, other companies have not opened my community. Asked, it is also white.
People who have listened said that the effect of Tung Tong can be. Telecom's expensive point. Another article in 2003:
Overview Nanjing broadband Internet access
First, family users
At present, there are three broadband Internet access to ADSL, LAN and CABLEMODEM. ADSL is the access method of Nanjing Telecom's push, which uses a twisted pair of telephone to provide 512 kbps to 1 Mbps access rate. There are two kinds of billing methods and months. Since the ADSL outline is low, it is not possible to transmit analog TV signal. The original telecommunications lane connection is not good, and the line aging is aging, and this model is high, and many lines need to be retest. Generally, as long as the user's telephone bureau is transformed, the user can apply for this service. At present, Nanjing City has basically realized the city.
The LAN access method follows the company's local area network construction mode. The user's computer must install the NIC and access the switch to the building through the five-catered lines, and then connected to the metro network or the Internet. At present, the operators engaged in this approach in the Nanjing market mainly include Netcom, Tiemong, Great Wall Broadband, Die's Network and Telecom's part of the broadband community in this way. His feature is that users theory can reach 10Mbps. The disadvantage is that the actual rate of the user needs to be re-wiring, the user's actual rate is subject to the limit of the line rate of the metro network or the Internet. Since the portal operator does not have the Internet export, it is necessary to rent other telecommunications, Netcom, Unicom Internet exports, cost-based considerations, lines or fiber speeds are often low, which constrained LAN actual access rates. Family In use This access method If the five types of lines do not have five types of lines at home, it is necessary to use the bright line mode to a certain extent. The LAN access method is in units of cells. Many cells have not been adopted, and the actual use is not wide, and because of the operators of each cell, if the user transfer machine is more difficult. CABLEMODEM is an access method of Nanjing Banglian Cable Radio and Television Information Industry Co., Ltd. and China Netcom cooperation. Because it uses the original Nanjing cable TV network to perform data transmission, only two-way transformation of the wired TV network, can provide theoretically upstream 10Mbps, down the access rate of 40Mbps. Now the two-way transformation of Nanjing Cable TV Network is basically completed, and most of the Nanjing City are mostly. CABLEMODEM uses cable TV terminals that do not need to rearrange, do not affect beauty. Since the cable TV network is shared, the bandwidth of Cablemodem is shared. Many people will worry that in case the number of Internet people, the speed will be reduced, where we help you understand how CableModem's bandwidth is. At present, the Nanjing cable TV network is
750M
with
860m
Bandwidth network system, a fiber node service cell has 500 users, and each serving cell on the system can transmit hundred cable channels at the same time, and the current analog TV does not use so many channels. CABLEMODEM can modulate the bandwidth of 40Mbps in a single cable channel. The bandwidth is improved based on the number of copies of each fiber node broadband user to increase the bandwidth of the corresponding number of CABLE channels. At present, Nanjing CABLEMODEM individual users can enjoy a single-threaded download of 100KB speed.
Second, business users such as enterprises, Internet cafes
Broadband access from business users, Internet cafes, is the profit hotspot of major operators. The access methods that home users can use can serve business, Internet cafes, etc., but the initial cost and monthly use fees are significantly higher than home users. At the same time, the high bandwidth and high service quality of the operating user, while also producing fiber access. At present, operators such as telecommunications, Netcom, Tietong, Great Wall, can provide this access method.
LMDS is a wireless broadband access method that enters the Nanjing broadband access market, China provides services for this access method. His advantage is that the layout is convenient and can bypass the "last kilometer" problem. However, since the wireless broadband access is easy to affected by the climate, and the technical development direction is not clear, the main telecom operators such as Telecom, Netcom have not adopted this access method.
