In what would be an important moment in WiMax’s lifecycle, Sprint is likely to choose WiMax according to WSJ. Sprint Nextel Corp. is expected to announce as early as today it is choosing a nascent technology known as WiMax to build a new wireless Internet network in the coming years, people familiar with the matter say. The move would mark a significant win for backers of the new technology, such as Intel Corp. and Motorola Inc., while it would be a setback for wireless pioneer Qualcomm Inc, which is behind a rival technology.
