Ok that was another issue I was concerned about since they dont use direct hook useing Wi-FI to work. If I am wrong please correct.
You aren't wrong... but that is also by design. This is a complex and likely confusing subject, so it isn't unusual for people to get things mixed up here. I'll generalize some of the info, but it'll also be less than everything to know on the subjects I'll mention.
Wi-Fi is the generic term used for the wireless transmission of computer networked devices. I believe there are around 6 frequency ranges ( there can now be more but I may not have heard of them yet ) commonly used for these devices and among them, some include the 2.4 Ghz and 5 Ghz ranges many people will have heard about often. These devices do not use all of those frequency ranges, just a portion that was assigned to them. These also use protocols specifically made for networking these devices. The designed power used for this set of devices is not very strong on purpose. The reason it isn't strong is so several "networks" can exist together in a general local area so they are less likely to interfere with each other. If two are using the same frequency/channel, they must share it and therefor are slowed down since each has to wait on the other at times.
Bluetooth is yet another 2.4 Ghz frequency device protocol also used on computer devices. Initially made for computer peripherals for short ranges and using a lower power level with around a 30 foot range ( now they also have a higher power setting on some devices ).
Then there are the even more generic computer devices that also use another of the 2.4 Ghz ranges. These are often keyboards, mice, and other similar devices. They typically have proprietary protocols used only by that device and it's related "dongle" that is used to connect to a computer. This is the type of stuff that is generically called simply wireless by most of us.
RC radios also have used many different frequency ranges used currently and in the past, the more commonly sold and current ones also use a portion of the 2.4 Ghz range ( another less common but certainly used frequency is the 900 Mhz and then the older AM/FM frequency/channels as well ). On the 2.4 Ghz frequencies used, several protocols and are not the same ones used by the Wi-Fi devices previously mentioned. Unlike the Wi-Fi signals, these have enough power that can allow control of the RC aircraft for miles if the line of sight is good enough for the frequency range they operate in. A wireless "dongle" that is used by RC radios is using the same RC radio frequencies and protocols, not the same ones that the other 2.4 Ghz wireless dongles are using. They are simply put, a RC receiver that can plug into a computer to be used most often as a game controller or joystick type of device.
Cordless phones are another set of devices that also use yet another set of different 2.4 Ghz ( and others ) frequencies.
Cellular phones have a lot of different frequencies that they use as well. Just to add to the confusion ( really it's just the complexity but still )... there are some RC airframes that even use a smartphone for their controller.
So to summarize it... you are correct that the devices you mention do not use Wi-Fi ... but it is by design since different protocols are being used by Wi-Fi than the other devices that just so happen to also use a 2.4 Ghz frequency ( or other frequency ). "Millions" ( on purpose exaggeration ) of devices use 2.4 Ghz but they are each in their own range of that frequency and each use their own type of protocol to talk to each other.
