When the Digital boxes are designed in Kenyan universities, and manufactured in China, that is good enough. We don't need to setup a huge factory if we don't have the means. At least, that will be a starting point. Many USA and European companies have their manufacturing in China, including Apple, HP, DELL e.t.c.
Don't forget the golden rule of innovation "Imitate then innovate". Tata and Huawei, and ZTE perfected the art, and now they are bigger than the economy of most African countries combines.
