When i am inside of my house. Can perfect connection to the wifi. When i go outside the wifi is in range but it refuses to connect to it
You know wifi is bidirectional thing, right ?

What does that mean
The device picking up the signal need to be equally powerful, to be able to send back.

The transmitter in a router is more powerful than the one in a phone. You may see an AP on the list but it isn't really "in range" because your phone does not have enough power to send back to it.

It could also be because when you are outside there are a lot more Wi-Fi signals leaking out of homes, causing interference, that would be blocked while inside your home with your router.

If you have a laptop, you could use it to get specifics on the WiFi situation in your area.
There is more than just signal strength to consider. It might help to also look at other things like interference, wifi saturation / channel ( are you competing on the same channel with multiple neighbors?)
Are you using a DFS channel? If so try a standard channel. Also you didn't mention which band you are using. Is your issue on 5Ghz, 2.4Ghz, both?
There are numerous open source free utilities you can find.
There are even some simple integrated command line utilities you can use to check the Wifi picture from outside.
If you have Windows, you can use Powershell:
If you have Linux, you can use the nmcli command:

Though it may sound counterintuitive, if you are in a very wireless-saturated area, it might even help for you (and neighbors if you can convince them) to turn down transmit power on the access point so that all of the APs in the area aren't "screaming" in competition.
Here are some more considerations:

(Since you are trying to connect outside, you might want to alter the 2.4 / 5g suggestions in that article. )
Maybe hour 2.4ghz network is misconfigured and you dont notice that inside.

Yes, true. That is a very good tool. The thought with using the laptop though is that it is portable, and would give a more precise picture of the wireless situation rom the outside where the phone / computer was intended to actually be used. ( i.e. would perhaps have different measurements as to the neighbors / interference, etc. ). Additionally, would measure the APs signal strength from the device at the intended location of use.
He can walk out the door watching it on a phone.
edit
along with the reported signal strength and noise in wireless.

Large patches of [grounded] metals count as obstructions, too.
This is rather flawed logic. My phone isn't nowhere near as powerful as a cell tower, and yet it works fine sending data back.
The big antenna on the cell tower/AP works both ways, it also makes for a more sensitive receiver than the one on the phone.
While it is possible that there is a hardware mismatch between tx and rx range (which could go either way), it is more likely that there is simply more interference outside.
You logic is also slightly flawed. You failed to consider the tall tower/mast giving it an unobstructed line. Additionally, there's likely no [general] interference since the cell carrier has an exclusive license for the frequency.
Actually, while the big antenna may "work both ways", it's generally a directional antenna (i.e., alble to direct more power in a single direction (as compared to an omni antenna in your phone).
Yes, that'll make it difficult for your phone (while outdoors) to transmit successfully to the inside.

It's actually a sh-t load of smaller antennas/cells, not like an old school satellite dish.
It keeps working, with a performance penalty, with wifi you get disconnected, the use cases differ.
You're kind of comparing apples and bananas.

Would you suggest that a cellphone antenna and a cellphone RF amplifier could just as competently replace normal cell tower equipment as long as it has an unobstructed view?
Nope, the capabilities are quite asymmetric. Both Rx and Tx, by orders of magnitude.
A directional antenna also works equally well both ways, ie, for Tx as well as Rx.
The directional part stands for the limited spread of serviced area, not a limit on Tx vs Rx.
Cell tower sector antennas are clusters of normal directional antennas (that improve both Rx and Tx), nothing special about them. They work just like dishes, ie, signal is improved both ways. If it improves sending signals to a location, it also improves reception from that location.
Red herrings aside, the actual problem with an asymmetric setup is that one side is more susceptible to unexpected interference, ie, the cell tower can drown out the increased noise with vastly more power, but the phone cannot.
Things are pretty much the same for WiFi. WiFi also often uses directional antennas that improve both Rx and Tx. Cantennas are one crude example.
No - I'm saying you're not standing on a mast with unobstructed view. Nor is your AP a cell tower with exclusive usage of the frequency (points you missed, ignore or didn't realize the importance of). Additionally, you wouldn't need an amplifier (in the same sense as you describe for the mobile device), hence your inquiry confused me. Nor is the cell phone equipment analogous to the tower. This is why it's poor to compare cellular to WiFi.
From your [attempt making an] analogy, you seem to still misunderstand.
I wanted to make an analogy about a meeting/discussion in a room and exiting to a hallway with other meeting rooms, but I'm not sure that's wise.
