How can I surf the Internet without a fixed telephone?

1, you can surf the Internet without a landline. The traditional telephone line system uses the low frequency part of copper wire (frequency band below 4kHz). ADSL adopts DMT (Discrete Multi-tone) technology, which divides the frequency band from 0KhZ to 1. 1MHz of the original telephone line into 256 subbands with a bandwidth of 4.3khz, among which people in the frequency band below 4khz are used to transmit POTS (traditional telephone service). The frequency band from 20KhZ to 138KhZ is used to transmit uplink signals, and the technology from 138KhZ to 65433DMT can adjust the number of bits modulated on each channel according to the line conditions, thus making full use of the line.

If there is no fixed telephone, you can install broadband internet access. The usage method is as follows:

1) Users only need to bring their ID card and a copy of the agent when they go through the formalities of accessing the network or changing it.

2) When filling in the business application form, please fill in the user application form in standard font with neat font and clear handwriting.

3) In order to ensure timely installation for you, it is suggested to fill in the contact number when handling business, and leave the contact information of two or more people who can be found at any time, so as to install the machine for this person in the shortest time.

4) After the business application formalities are completed, the company will open ADSL service for you within 2 working days.

5) If it is not installed within one month from the date of filling in the application form, it will be deemed as automatic disassembly. If necessary, please go to the business window again.
