China and Japan are working together to develop what they hope will become a worldwide standard: Both countries have a history of creating and using technologies that are different then the rest of the world, sometimes in hopes of setting a worldwide standard. Last year, the government in China mandated that Wi-Fi gear used in the country use a home-grown security standard. The government later relented. Japan has a history of using proprietary wireless standards, often because the market there is so advanced that it seems operators can’t bear to wait for worldwide standards to be set. This most recent 4G push may be an effort by the countries to try to keep a bigger chunk of potential revenues from the potentially huge future so-called 4G market within their borders, rather then paying European and U.S. companies for intellectual property and gear.
Any 4G technology is almost certain to be based on OFDM. It’s unclear at this early stage how WiMax might fit into a 4G future.
