I acknowledge that hundred-year-old history bores me but recent history fascinates me. Especially as it relates to technology. One thing I have learned is that whenever any technology tries to take on Ethernet, it loses. There were a few competitors over the years and in each case, Ethernet morphed and became even more popular.
WiFi is wireless Ethernet and as such, part of me always thought WiFi would morph, making it difficult for WiMAX to be successful.
To date, this really hasn't happened but perhaps that will change as a result of Intel's Rural Connectivity Platform (RCP) which allows WiFi signals to be sent up to 60 miles at a cost of about $500 per router.
While this technology is in its infancy, the existing standard always has the advantage as there is such great economies of scale due to the massive production runs the incumbent enjoys.
Will RCP replace WiMAX? I am not sure... But it seems it will certainly be a serious competitive threat in some instances and as
