How Do I Extend My WiFi Signal To Another Building 400 Feet Away

Have you ever wondered why we cannot boost the internet to maximum power and extend the range? To answer, we did some research and will try to help you.

First of all, let us tell you a little about the Wi-Fi itself and why it keeps getting weaker and weaker every time you get far from it.

The tiny adjustments in the waveform that carry the data are much more straightforward for equipment to understand but as speeds get faster and faster, the modulation schemes are more complicated and more prone to errors and interference.

So, the farther away from the access point you get, the slower you have to go. If your access point sends out a signal and does not get a reply from another gadget acknowledging that it received the signal, the AP will keep slowing the speed down and down until it gets a response – this is a significant part of the reason that speeds get slow if you walk farther away from your router.

As we demand faster speeds for streaming gaming and file transfers slowing down our Wi-Fi to make it go farther isn’t a viable solution. The Wi-Fi standard does not have a high transmit power, to begin with, to comply with telecommunications laws in different countries, for example, in the United States, you cannot go higher than 200 mill watts, and most routers get configured by default to transmit at this maximum.

You cannot turn it up any further legally, however, that does not mean that getting a better Wi-Fi range is a fool’s errand.

First way: PiFi

In one of the most common scenarios, you have two buildings; one with internet and one without. Usually, the house with the Internet has enough signal leaking out about 20 yards away from the last wall of the house that allows a PIFi at the second location to get installed outside and grab the signal up to one mile away.

The PIFi is acting as a bridge between the two locations to grab the Internet that is leaking from the outside of the house and pass it to a new router inside the second building. By placing the PIFi outside the walls of the structure you can grab the signal with the best potential to bypass the outside walls, with a second structure allowing the router inside to get the best possible internet.

This new router then retransmits the internet allowing multiple devices that are Wi-Fi enabled to connect this system is universally compatible with any Wi-Fi enabled device things as PCs, phones, tablets, smart TVs, home devices, and security cameras.

They all allow you to stream your favorite shows, social media, and even music and game over this repeat. Anything that is Wi-Fi enabled can connect to this new router and enjoy the internet from far away.

Focusing the signal

One trick that works well is to focus the Wi-Fi signal in one direction. A typical home router has omnidirectional antennas, where the signal gets transmitted evenly in all directions, but if your router is at one end of your house and your couch is at the other, that is not the best setup.

Instead, you can get something called a patch antenna which looks like a big flat panel and sends the signal out in one direction. They are more common in commercial settings or at trade shows but nothing is stopping you, for example from sticking one on the side of your house and blanketing your backyard with a strong Wi-Fi signal.

Long Guard Interval

Another way that gets built into some Wi-Fi standards is the use of a long guard interval. Between short parts of the transmission called symbols are short time intervals before the next symbol gets sent. These guard intervals are there to cut down on the interference between symbols, so if they are short, you get more data, but if they are long, you get less interference.

Therefore, the longer-range at the expense of some speed Wi-Fi 6 is introducing extra-long guard intervals for outdoor use where ranges often need to be longer.


Another winning strategy is to cut down on interference in other ways. You can do this by using narrower channels, so by using 40 megahertz instead of 80 on the 5 gigahertz band, as well as making sure that you do not have unnecessary transmissions flying around your house from baby monitors or Bluetooth devices that you are not using. This one can make more of a difference than you might think a huge part of how wired Ethernet has gotten faster has simply been by cutting down on noise inside the cable.

Lite Beam M5

One of the best ways to buy Lite beam m5. The LBE-M5-23 was designed to be an affordable cost/performance solution for long-distance, wireless broadband bridging. It operates the worldwide, license-free 5 GHz frequency range and features high performance of up to 100+ Mbps in real outdoor throughput and an incredible range of up to 30+ km.

However, I would not expect too much new technology soon that can extend the Wi-Fi range without adding more antennas in something like a mesh network speed, and range is always going to be a balancing act.
