It's not like it's driven by Moore's Law or anything - it's a simple matter of MONEY... the WiMAX sales guys want to lock you in - make you BELIEVE that it's the way to go...
That's how I remember 802.11b and Wi-Fi being sold in 2001.
A man named Michael Young (YDI)/karlnet/TerraBeam/Proxim was selling 802.11b Lucent/Orincoco AP1000 for $900 each. The laptop cards were an extra $110 each. A pigtail was $50 The cost to install a customer with a YDI (3com) ethernet convertor was near $900 per customer and 2.4 AMPs were around $400 each. LMR400 coax cable was $3 foot.
Then along came Mikrotik......I believe they could do the same in the WiMax field. We do need the radios with the extreme receive sensitivity that compares to WiMax product. if not the WiMax standard 802.16 itself. I also agree that WiMax is being hyped, and is way over priced. Seems like it would be a good time for Mikrotik to enter in and steal the show.
I personally am seeing local telco deploying a licensed product (802.16 protocol) that allows people to connect 4 miles away with an indoor device. They are passing them out to customers for self installs.I have talked to several of their customers. People who had called me first but I couldn't reach them with current system even though my tower is closer to them by two miles.
Pretty hard for me to tell people I am going to bolt some ugly antenna to the outside of their house and oh, by the way, there is an installation fee for that.
I have no choice but try to weigh my options in the WiMax arena.
Again, I eat, sleep, breathe Mikrotik. I have to believe Mikrotik would have a huge impact on Wimax if they decided to. Maybe it could even be re-named Mikro-Max, or possibly Max-Tik?
802.11n would be good for starts!
