Cover StoryUser-Generated Devices (UGD), allowing people to enjoy themselves making their own equipment with friends, are making a showing in the electronics industry, fueled by the outsourcing of development and manufacturing, open constituent technologies, and other trends. Only companies capable of discarding the paradigm of volume production will be able to evolve apace with this new dimension in user participation.
Special InterviewsThe step-down direct-current (DC)-DC converter integrated circuits (IC) used in mobile phone power supplies are shifting rapidly to higher frequencies. The reason is that a higher frequency makes it possible to make peripheral components dramatically smaller and thinner, contributing significantly to smaller and thinner handsets. Overconfidence is dangerous, however, because the higher frequencies can degrade characteristics. A careful evaluation of the merits and demerits is essential.
Mobile World Congress 2009, the largest exhibition in the world in the mobile phone field, was held recently. Many major mobile phone operators around the world are planning to adopt Long-Term Evolution (LTE), and the congress revealed that the focus right now is on just how mobile phone services will evolve during the transition years until then.
