Analysts have been predicting consolidation in the Wi-Fi market but not much has happened yet: A few companies, however, have reached their limit. Bermai, a Wi-Fi chip maker, recently went under. Apparently there are some hints that Legra, a WLAN switch developer, may be on the way out. Ever since AirFlow switched its strategy to license its technology rather than sell products, observers have wondered if the company would stay in business for long. The upside is that some companies continue to get stronger.
