# WIFI over wires [closed]

So, guys I have made wifi gun a but it seems not working as there are a lot of trees between my friend's wifi and my home ( 1km distance ), So is there a method to convert wifi to wire and transmit over here, So I was thinking about connecting a wire to my wifi antenna and dragging that to his house.

Any suggestions or advice?

• Yes. It's called "Ethernet". – Puffafish Sep 24 at 12:27
• Hahaha next thing you'll be wanting phones that work over wires too. – Brian Drummond Sep 24 at 12:30
• There's a reason why that YouTube video has gotten so many negative votes. – rdtsc Sep 24 at 12:43
• What in the name of little green boogers makes people think that videos are a good way to distribute technical information? To build a copy, you need detailed plans (drawings,) written descriptions of how to make and assemble the parts, and a list of troubleshooting steps for when something goes wrong (and something always goes wrong.) Videos offer none of those things. – JRE Sep 24 at 12:50
• Sorry, but this isn't a "gimme the circuitz" site. You've asked on an electronics engineering site for questions and answers on technical design so you can expect to have to have some knowledge on the subject to phrase a decent technical question. – Transistor Sep 24 at 13:09

This has got off to a bad start, but the answers are really almost there: WiFi and Ethernet are closely related through both the technology and the IEEE standards body that defines them.

The absolute simplest wifi-wire-to-wifi would be unscrewing both antennas on the APs and putting a length of coaxial cable between them. For short links this would probably need an attenuator, but a 1km piece of cable should attenuate quite effectively itself (-30dB maybe?). I'm not sure if the latency would prevent this from working effectively but I don't immediately see why it would.

Someone claims to have actually done this. In their case they already had the cable installed and needed to build adapters.

The "correct" solution is ethernet-over-coax or ethernet-over-fiber, but both of those require specialised conversion equipment.

You might be able to make "twinax" (twin coaxial, used for satellite TV dishes) work instead of ethernet cable with appropriate baluns, but this seems like a lot of hassle and I wouldn't try it unless the link was already there.

What will almost certainly not work is a long piece of unshielded cable, like bell wire, speaker wire, or household mains cable. You can do Ethernet over junk for short distances but not long ones.

• from my experience, only -30dB of attenuation over 1km would be an exceptional good cable... I doubt its more. Cat 5e allows just some ~25db insertion loss for 100MHz. And this is roughly what Cat5e twisted pair offers - for 100m. (of course 6,7,8 are a bit better, but not in magnitutes) – schnedan Sep 24 at 13:34
• I was thinking of maybe,stepping down the frequency of the wave and transmit it over cables and do the other stuff at the other end,.....I don't have enough experience to tell wether it will work @Transistor that is why I posted here,take this technical shit,LOL – ElementX Sep 24 at 13:40
• Yes, it'd have to be really low-loss. LMR-1700 (lowest loss standard product that Times Microwave sells, a very large 1.7 inch diameter coaxial cable) does about 5.7 dB/100 m @ 2.5 GHz, or about 57 dB at 1 km. Something more sane like LMR-400 (Times version of RG-8) is 22 dB / 100 m. There's a reason that DOCSIS cable internet stays mostly below 1 GHz, the attenuation is much more friendly there. – Peter Sep 24 at 13:41
• Guys if i am going to buy coax,It would take me more time than downloading Forza horion 4 via GSM – ElementX Sep 24 at 13:43
• @Peter, and the prices! Virtual Air heliax coax for this kind of length and frequency will cost $500-$1000. Better to go with RG58 and a DSL modem. This is a great "youtube" idea, if the OP can add some fire & explosions, a few sprints through the forest, a social experiment, and some drone aerial shots. Extra points for a Call-Of-Duty theme. – P2000 Sep 24 at 14:50
