A huge costly mistake for Sprint trying to grow subscribers. Nextel's network was incompatible with Sprints, just a ton of business and technical issues. Sprint was always trying to be on the forefront of technology whether wireless or fiber. They spent a ton money on a project called ION that was last mile fiber to businesses, ahead of there time but a ton of costs actually laying down fiber doomed it. Poor timing for a lot of ideas and projects I saw. Source: ex-sprint emp.
