We're still waiting for a good replacement of our purewave wimax. Telrad still operates with this soon to come promises. These were announced at alvarion times. I dont believe purewave will do their long announced multi-carrier bs and I dont believe Telrad will ever do 256 QAM and mu-mimo.
Lots of marketing-BS to stay in market. Looking at the price range of this products 256QAM in both directions is a must have *now*. If they want to sell options they have to have a release date and a cash back guarantee if they dont meet this. We dont use PMP450 as we need higher output power for our licensed spectrum. Purewave does 33db/port. Lets see if the announced 450m stuff will do higher power in 3,5GHz. -----Ursprüngliche Nachricht----- Von: Af [mailto:af-boun...@afmug.com] Im Auftrag von Adam Moffett Gesendet: Donnerstag, 14.

I'm assured that all of my problems are fixed when we upgrade to LTE. I'm not sure I trust the opinions on LTE. People are very focused on the NLOS performance, and they are still experiencing the "wow" factor of getting a connection working in a weird place that seems like it shouldn't work. I haven't seen much conversation about whether the connection you get is something supportable. Wimax always had the problem that if the customer tells you something is wrong you have a hard time proving whether there is or isn't a problem without going on site. I don't know if LTE on the compact really changes that situation. I do know the Gemtek CPE still has no damn ethernet stats. In LTE the AP can use a 20mhz channel at 64QAM and get close to a hundred meg aggregate on that. You can pay a license fee for dual carrier mode and use 2 x 20mhz channels to double that. With MU-MIMO at some future date they expect to double that. So best case is 400meg (I believe). Since using 40mhz might not be practical, divide that by what you can actually use. They do have a capacity planning spreadsheet if you can get in touch with someone who has it.
