April 28, 2011 at 17:17Modding Yota Egg
In the comments to the article “Testing Wi-Fi antennas for receiving WiMax”, we discussed with bepcyc and drunken the possibility of adding Wi-Fi and WiMax antennas to the Yota Egg mobile router.
In this article, I realized this idea and got a good profit from it.
Opening the egg was unexpectedly difficult. I found the first screw easily. As usual, he was hiding under a sticker on the abdomen of the device. After it was removed, I began to separate the lower part of the body with a sharp knife, everything went smoothly enough. Then everything stopped at the top of the case, where the power button is located. I could not find the second bolt, although I suspected its existence.
As you know, modders are divided into very smart and very strong. I, apparently, belong to the second category, because I decided that you just need to pull harder. You see the result in the photo:
It turned out that the head of the second screw was hiding under the power button. I have not seen such a solution in gadgets. How to remove the power button remains to be seen by my followers.
Next, you need to unscrew the 4 screws holding the battery, and apply moderate force to remove the battery from the board:
Now you need to remove the plastic parts from the LED block and the power port, disconnect the cable, and finally, remove the main board:
Inspecting the main board, I understand that most likely nothing will have to be soldered. In the photo you can see the connector, to which there is a mini-coaxial cable from the second board and two free coaxial connectors.
It is not clear which of the wireless interfaces they are responsible for. I decide for now to connect the pigtails to the free connectors: I unscrew
4 more screws and remove the daughter board. I already noticed that it has 2.5GHz on it, which means that most likely it is responsible for WiMax.
So it is, this is a WiMax controller, from which there is a mini-coaxial cable to the antenna on the main board.
A complete picture formed in my head. Two connectors on the main board are Wi-Fi. Without connecting external antennas to them, internal ones will work. WiMax is harder. You can connect the pigtail directly to the daughter board, but then we will most likely lose the opportunity to use Egg without an external WiMax antenna. Okay, I don’t have to wear this Egg in my pocket, I connect the pigtail:
Now I’d rather like to collect and test this whole thing. Armed with wire cutters and a sharp knife, I made holes to fix the three connectors. In the photo you see an extra hole. Chasing the symmetry, I lost sight of the fact that with this position of the connector, I can not close the case.
I did not worry much about this, because my task is to pave the way. One “engineering” model can be allowed to suffer for the good of society.
Connecting a WiMax antenna increased the speed of the Internet from ~ 6 to ~ 8 Megabits. It remains inexplicable that with the WiMax disabled, the Egg antenna works and produces a speed equivalent to that which was before the modification. The fact that I myself turned off the built-in antenna puzzles me a little.
An external Wi-Fi antenna increased the coverage area by 30-50%, but I used only one antenna. There is room for experimentation. By combining directional and omnidirectional antennas, you can achieve the desired coverage of a Wi-Fi network.
Let me remind you that compact WiMax (Yota) and Wi-Fi antennas are interchangeable. Pay attention to the article, the link to which is given before the kat.
In our office, the employer, for security reasons, does not allow connecting personal devices of employees to a corporate Wi-Fi network. This means that our gadgets (iPhones, Google phones, iPads, home’s, etc.) were out of work. My colleagues and I chipped in on the Internet and deployed a secret opposition network at work - a site not subject to audit by the company, a blocker site that provides ordinary employees with the Internet when the corporate channel crashes. The egg was chosen because of its compactness - it is easy to hide. It will work autonomously if we turn off the electricity for several hours.
The author does not call for independent modification of Yota devices and does not consider the scope for modifications a product shortcoming. Such actionslead to the development of fine motor skills, intelligence, and increased self-esteem can lead to equipment failure, injuries of varying severity, and clearly deprive the manufacturer of a guarantee. Attempts to repeat them are done at your own peril and risk.
