That is, the old-fashioned modem (cat) accesses the Internet.
Of course, the technology is much advanced now, and the network speed is not the kind of slow cat that was tens of K at the earliest time. The fastest cat in the family can reach about 10m, and watching online video is absolutely no problem.
LZ said Netcom doesn't need a telephone, and the wireless server may be used to transmit the Internet. This is a wireless data transmission technology, which is essentially through the telephone line (but note that it is not a "telephone", the telephone line is just a transmission medium here, and you can exchange it with network optical cable or telephone line). Do not believe, LZ can find that they still need to use MODEM when installing.
This kind of wireless Internet access is contracted by Netcom to some small technology companies, who are responsible for it, because many communities of Netcom have not laid optical cables, and this kind of wireless Internet access technology can just avoid this weakness.
Regarding whether to use telephone lines or optical fibers, there is no doubt that optical fibers have large traffic and sufficient bandwidth.
Different people have different views on whether it is the broadband of telecom or the broadband of Netcom. If LZ doesn't care much about money, it is recommended to choose China Telecom. To tell the truth, China Telecom is really the best in terms of service, hardware, laying area and so on.
However, if LZ pays more attention to cost performance, it might as well consider some broadband services of Netcom or Tietong. I use CTT monthly 1M, and the speed is generally around 40-50K during the peak hours in the daytime and at night 100k (after 10). There are few cases of disconnection. My family installed it in July, and it hasn't been disconnected once so far.
If LZ is equipped with 2M broadband, the network speed can be at least above 100k, and the speed is still good.
At present, both China Railcom and China Netcom rent telecom servers, so it must be admitted that the stability and speed are definitely not as good as that of telecom.
In addition, in addition to the wireless Internet access mentioned above, Netcom has also laid optical cables in some communities, which can provide ordinary Internet access services at a lower cost than telecommunications. Monthly subscription in 50 yuan 1M (unlimited).
And that kind of wireless internet access is actually good, as long as it is a small company, it has a good reputation and good service. There are many communities in the old mining area in the west that don't have ready-made networks, so many families choose this kind of wireless Internet access, which is cheap-1m China Netcom can have a monthly subscription as long as it is in 39 yuan, and the service is good-call the maintenance staff's mobile phone 24 hours a day without installing a phone.
My family has a relative of Cai Jiagang, who uses "COSCO Netcom", which is not bad. The speed of 1M can be stabilized above 100k, and sometimes the line is dropped, but it can be done in ten minutes by calling customer service, which is quite convenient.
