Right, 10 MHz licenses for sure. I believe the SAS knows about equipment capability and could handle whatever size the equipment had to work with.
Future equipment won't necessarily have the adjacent channel requirements to act as one. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Ken Hohhof" <af...@kwisp.com> To: af@afmug.com Sent: Friday, April 15, 2016 8:43:55 PM Subject: Re: [AFMUG] Telrad specs OK, fair warning, I am going by memory, but I thought the FCC was very specific that PALs would be 10 MHz licenses. So if you had 2 PALs in the same area, or were using GAA, could you request and receive a 20 MHz contiguous allocation from the SAS? I guess maybe, although I would be very surprised. And if you got lucky and the SAS assigned you 2 x 10 MHz adjacent channels, I think that could change at any time.

I would assume the SAS would support larger channels. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Ken Hohhof" <af...@kwisp.com> To: af@afmug.com Sent: Thursday, April 14, 2016 11:10:45 AM Subject: Re: [AFMUG] Telrad specs Are you talking licensed spectrum, or 3.65 GHz? Going forward, I don't think we should plan on 20 MHz channels in 3550-3700 MHz, even now under Part 90 rules it is somewhat unrealistic. If you are talking about aggregating non contiguous 10 MHz channels, that's different. -----Original Message----- From: Adam Moffett Sent: Thursday, April 14, 2016 11:05 AM To: af@afmug.com Subject: Re: [AFMUG] Telrad specs Are we talking about LTE or Wimax? Of the 4 Wimax systems I've used, the Compact is probably the worst. 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.
