A man who succeeded in communicating using a 'wet string' instead of a LAN cable for ADSL connection appears

Asymmetric Digital Subscriber Line (ADSL), an Internet line that uses existing telephone lines for communication, generally uses ADSL cables made of copper or aluminum wires. However, engineer RevK has demonstrated that ADSL signals can be transmitted even through a wet cable.

RevK®'s ramblings: Please upgrade me to ADSL over wet string

ADSL is a technology that transmits signals over cables using multiple frequency bands. RevK, who works for the British ISP Andrews & Arnold, conducted an experiment to verify the rumor that 'ADSL signals can be transmitted even through a wet string,' which has been said to be theoretically possible until now.

So RevK, who works at Andrews & Arnold Ltd , a company that provides Internet connectivity and VoIP technology, actually conducted an experiment to test ADSL communication using a wet string.

First, RevK tied a string that he had soaked in salt water to a clip and connected it to

the RJ11 .

The other end, about 2m away, was connected to

a DSLAM , which provides broadband Internet connection.

When we measured the communication speed, we confirmed that the communication speed was 0.06 Mb/s upstream and 3.5 Mb/s downstream.

However, RevK said, 'In our experiments, we had to wet the string about every 30 minutes to avoid a complete loss of communication, which would result in a loss of communication,' emphasizing that this is not a commercially viable product .

In addition to the wet string experiment, researchers have also used barbed wire as an Ethernet cable.
