Does the property office need broadband connection?

Need a computer. Of course, the information tools that property companies need are computers, internal network systems (routers, switches, printers, computer equipment, attendance machines), various application software, and property management information systems.

Everyone should be familiar with these tools, but the unfamiliar ones may be property management information system, that is, property information system, property management software and property software. These names are different, but they refer to the same thing

Broadband connection is a relative description when the serial number of basic electronics and electronic communication description or electronic circuit contains or can handle a wide frequency range at the same time. The larger the frequency range, that is, the higher the bandwidth, the more data will be transmitted.

The principle of broadband connection.

The traditional telephone line system uses the low frequency part of copper wire (below 4kHz). ADSL adopts DMT (Discrete Multi-tone) technology, which divides the frequency band from 0 khz to 1. 1MHz of the original telephone line into 256 subbands with a bandwidth of 4.3khz.

Among them, 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 frequency band from 138KhZ to 1. 1MHZ is used to transmit downlink signals. DMT technology can adjust the number of bits modulated on each channel according to the situation of the line, thus making full use of the line.
