Steinbrecher was a company that has breakthrough in spread sprectrum technologies. Started out as radio telescopes for government research. TLAB will always be in the middle of the telecommunications industry. However they are getting serious competition from escepially Alcatel. NN is also a company that is developing more and more.

A recent article in Electronic Business (November issue) cited a Allied Business report suggesting a ramp up of WLL subscribers from near 0 to 266m by 2006. 84% of these subscribers will be in developing nations. Qualcomm, Motorola and Nortel are expected to dominate this market. STRelecom, Diva Comm., Phoenix Wireless are targetting rural regions. With fixed subscribers, increased sectorization allows an operator to offer more capacity, but... another interesting thing we have noticed is that some WLL operators are also opting for a 5-10% component of mobile subscribers who can roam within a system and in between compatible systems. So, it seems that you really can't design for a "pure" WLL system, where you'd expect no one to roam and you could plan your network such that only a handful of few mobile stations would be in soft-handoff at any given point of time. There's not much of a trend that I'm aware of for the other way around (i.e. cellular operators offering a small WLL subscriber base). Please post if you have more information/examples of these trends. While there are interesting network and system design issues there are licensing/legal implications too -- for instance is it legal for an operator who has purchased spectrum for WLL to offer limited mobility?
