These are tough times for everyone and Wimax is no exception. Nokia has stopped making their only Wimax-enabled device, the Nokia N810 tablet, only 9 months after it was unveiled. Though it hasn’t ruled out Wimax support in future handsets, this is a temporary setback for the technology
(link).
In addition to that and on a related note, Intel has lost significant amounts of money in acquiring Clearwire which depends on devices like the N810 for the success of its service.
Despite these setbacks, there is hope for Wimax. Ari Zoldan has an interesting article on why the predictions of the death of Wimax are premature (link). We’ll need to wait it out and see where we are in a year’s time when hopefully, the economy will be in a better position.
