Is increasing tx power dangerous?

[im_not_200iq]

So i just got a router from mikrotik and i want some better range.

 

Is increasing tx power level dangerous? If so, what are safe levels that will still work?

[Kilrah]

TX power of what?

[matt0725]

if by dangerous you are talking about dangerous for your health similar to the most recent LTT video, no. turn it up as high as you need/want/can to get the performance you are after.

 

If you mean for the hardware, probably still no, itll just run a little hotter to output more power.

Im talkin hardware, fk that flat earther bs.

 

But like what level would it be safe to go up to?

 

[Lurick]

Provided you bought it configured for your region then it should have limits on the max TX power you can go for that region, otherwise double check and make sure you're not setting it to something above what your local region allows for wifi TX power but to be honest unless you've got a super overkill antenna with TONS of power (like needing external/dedicated power) then you don't have anything to worry about.

tx(transmit power) i think.

The deafault whas 17

[Kilrah]

If you can select it then the hardware can do it...

[Lurick]

Remember though, just increasing TX power doesn't mean you'll have better coverage if the device on the RX end can't produce enough power to talk back to the AP. Additionally just increasing TX can cause other problems such as neighbors having issues connecting, roaming issues, etc.

Could it have some kind of effects tho? like that dosent realy help.

Same way you could oc ur cpu to like 5ghz. Am i oc or smth?

1. The neibhurs shouldnt be an issue.

2.What other issues can it have?

3. is there lke a number you could name? or smth?

Nope, won't hurt anything, but won't help range much normally. No reason not to try it.

It varies depending on your environment but generally 25 or below has been fine for me running two APs and not causing any issues. Here are a few potential "issues" you can have:

Could i do 40? i realy dont give a fk about the law or the neibruhs(mainly cuz they not realy that close)

btw im using some home router my isp gave me.

It won't let you transmit higher than you legally can. Most routers are running near the legal limit anyways, so you can't increase it much.

While you don't care about the law. Depending on your government they can and will find out. Here in the US that would probably get you a $30,000 fine from the FCC. There was a case in the US where ASUS was shipping routers that transmitted higher than legally allowed. They settled with a big fine. I personally wouldn't risk it.

I dont exactly live in the us. But i do want to know the legal limit.

also i live in an area where i woudnt realy be conserned about them finding out

Also how do they find out?

They can detect those sorta of things. There was a guy in NYC who's ASIC Bitcoin miner was broadcasting a 700 MHz signal. It wasn't intentional on his part but he was broadcasting on the part of the 700 MHz band used by T Mobile. T Mobile noticed the issue, informed the FCC and bing bang boom the FCC was knocking on that guys door. 

 

As far as the ASUS router goes, Im not sure how they figured that one out. My guess is the FCC maybe was in an area with that router and noticed it was broadcasting too high. Keep in mind that the airwaves are controlled by the Government and some bands are shared. For example parts of the 5Ghz band fall in to use by Radar, thats what the DFS channels are. I wouldn't doubt it if FCC personal just drove around looking for rouge signals. Especially if there was maybe  an airport, military base or other critical thing in the area.

Contact what ever authority manages the airwaves in your country. They might have a Website.

btw how do i convert dbm to mhz?

You dont. Mhz is the band use. dbm is used for signal strength. 

 

You cant change the band that WIFi operates on. Because the WiFi band has unlicensed use. Other bands require a license from the government to use.

Well, it really pisses off the neighbors cat when it's hair starts falling out. No, turning up the TX power won't "hurt" anything but your existing reception. Making it "louder" won't make it any "better". It only makes the signal noisier and far less reliable. The ONLY reliable way to get a decent signal is with more coverage and that means more hardware.

This does need to be stressed more, that the higher the power, the more noisy the signal.  Turning it DOWN can actually end up with faster performance as you are operating the signal amplifier in a more efficient range.

 

Its the same with any amplifier, there is a sweet-spot where it introduces the least noise and gets worst the closer you push it to its limit.
