Russia Requires WiFi Registration
While WiFi wasn’t as broadly unlicensed in Russia as it is in most other industrialized nations, your can not find wifi antenna anywhere a state regulator exempted indoor use in certain bands from registration. The Mass Media agency apparently believes that it has the authority to compel this, although there’s some doubt by observers as to whether it really falls in their purview.
