3650 to 3700 Mhz spectrum information
Introduction to the spectrum
The FCC has a relatively straightforward procedure for getting a license and operating in the band:
1) Obtain a nationwide, non-exclusive license using ULS
Easily done via a self service web page on the FCC site. Anyone can obtain a nationwide non exclusive license with a credit card. The fee is $210.00 according to the FCC fee schedule
2) Before registering a station, examine ULS for nearby stations.
Again this is easily done via a self service web site However that database isn't the whole story. The FCC grandfathered in several existing earth stations.
Here is a map of the ground stations which may be of interest:
I have created a yahoo maps mash up of the stations in Southern California.
So begins my quest to gain access to the circular 150km exclusion zones which are in place around the incumbent earth stations. Please see appendix D (starting on page 54) of this fcc document for much more information on exclusion zones.
3) Obtain FCC-certified equipment (fixed, base and mobile equipment operating in the band must incorporate a "contention-based protocol").
I recommend Ubiquiti Networks equipment based on good feedback I have seen on the WISPA wireless list
4) Register each fixed and base station using ULS. Easily done via the FCC website.
Contacts/Organizations
Some people and organizations I have come across researching persons and companies involved with satellite and network operations.
From his resume I discovered:
1) Society of Satellite Professionals International - SSPI Southern California Chapter
2) Society of Motion Picture and Television Engineers [http://www.hsmpte.org/ Hollywood Chapter
3)Society of Broadcast Engineers Los Angeles Inland Empire chapters
4) National Association of Radio and Telecommunications Engineers (couldn't find any chapter information).
5) Society of Cable Telecommunications Engineers Southern California Chapter
Networking with members of the above organizations seems like a good investment in support of gaining access to the spectrum in an efficient manner.
3650mhz Southern California Stations (Chatsworth and one of the Sylmar Stations)
According to the grandfathered FSS earth stations list the Chatsworth Ground Station (34°14'20.70"N 118°34'11.50"W) is owned by McKibben Communications.
Doing some research into the company shows that is was renamed to FiberSat Global Services. Searching for FiberSat Global Services shows that it was renamed and sold to Access Integrated Technologies which is a public company. Contact info for the company.
One of the Sylmar stations (34°18'55.00"N 118°29'12.00"W) is operated by FiberSat Global Services LLC. Same company different name. :)
3650mhz Southern California Malibu Stations
I have split the ground stations in Southern California (referenced in this document) into 3 sections.
Stations in Malibu
Stations in Chatsworth/Somis
Stations in Sylmar CA.
One of the first terms I come across in the document is Fixed Satellite Service
Searching for fixed satellite service at&t (at&t is listed as the licensee of the malibu stations ) leads me to a company called Loral Space & Communications LTD which purchased AT&T Skynet. They are a public company The records they are required to maintain are most useful. :)
Searching the FCC licensing website for loral leads me to lots of expired licenses and two active licenses (unfortunately I can't bookmark the search itself just individual results)
[http://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=210736 WPOJ997
[http://wireless2.fcc.gov/UlsApp/UlsSearch/license.jsp?licKey=210737 WPOJ998
However I'm not sure they belong to the same Loral Space & Communications company. They also aren't licenses for 3650 mhz frequency.
Ok. So who is operating the AT&T satellites mentioned in the grandfathered earth stations list?

Apologies for the formatting.
So searching on the exact call signs (E980066, KA273, KA91, KB32) returns nothing. OK Time to get a bit more creative. I did a search for 1700 South Bardman Avenue which is the street address of the FSS site. There are 3 base stations here. Or at least 3 I could see.
According to this filing one satellite is operating in the 3650 range.
SITE ID: 1 LOCATION: 1700 SOUTH BARDMAN AVENUE, LOS ANGELES, MALIBU, CA
34 ° 4 ' 49.70 " N LAT. 118 ° 53 ' 43.90 " W LONG.
I was at that location yesterday, or more accurately I was at [ http://maps.google.com/maps?f=q&hl=en&geocode=&q=34%C2%B04%2749.70%22+N++118%C2%B053%2743.90%22+W&ie=UTF8&ll=34.088846,-118.894056&spn=0.001051,0.00235&t=h&z=19 mullholland highway and bardman avenue]. There is a gate there which prevents access to the facility. I presume the facility is unmanned but who knows.
So the satellite at the facility which operates in this range is owned by [ http://www.ses-newskies.com/ New Skies] Well I imagine they would be easier to negotiate with then AT&T.
