So what is these bid are for?

 

The PCS/AWS-2 H block.

Pardon my ignorance, but why, in layman's term is 1900mhz so popular? Or can someone direct me to a location where I could my answer.

 

I wouldn't say it's any more popular than any other spectrum. The reason we are talking about 1900Mhz in this thread is because that's what this H block spectrum being bid on was, 1900Mhz.

Dish is interested in the 1900 MHz H Block because they already own spectrum adjacent to it.

All usable spectrum is popular when it becomes available. Because there is a limited quantity available.

I really want to see what Dish does with this spectrum and its other spectrum. They will have to use either T-Mobile or Sprint to host it, most probably Sprint. But if they are having ambitions of OTT play, I am not sure that what they have is enough. Plus what they wanted to do with their own spectrum in conjunction with the Lightsquared spectrum is now moot (reverse uplink and downlink). It's going to be interesting.

So according to the spectrum map, it looks like Dish only bought the H block for the western half of the US?  Is this true because I would have thought that Dish bought almost nationwide licenses for the H block.

I don't know.  But I can tell you this...there is already activity on the spectrum analyzer in Wyoming on H block.  But not in North Dakota, South Dakota and that part of Nebraska not colored in.

 

I almost drove off the road when I discovered activity on H block in Wyoming.  It started near the border and was full intensity about 30 miles in.  Staying a steady -90dBm or so.  But it was not a full 5MHz wide.  Seemed like approximately 2-3MHz wide.  And it was uniform.  No matter where I went, even 200 miles inside Wyoming.  Like it was beamed from space.  

 

It stayed within 5-6MHz of -90dBm every mile.  Behind buildings, behind hills and mountains.  It had to be a satellite.  And it went away within 20 miles of driving out of Wyoming.

Dish doing FIT tests? Or Sprint doing it for them?

If it's being done by satellite, it would have to be Dish.

If coming from a satellite, I would think you would need a dish type antenna to be able to capture enough signal and you would have to have it pointed at he satellite.  But after saying that, if you think about a mobile GPS receiver, it captures data from multiple satellites without a dish type antenna.   I would also question if Charlie would have a satellite in orbit that could transmit on those H block frequencies.

It was on a spectrum analyzer, not a phone. If I can keep a rock steady signal through 200 miles of desert mountains, it can only be from space. I can come up with no other conceivable explanation for the signal. I can pick up satellite signals in 2000MHz on a spectrum analyzer. They are beaming the signal to the surface of the earth.

It would amaze me that the antenna in a Spectrum analyzer could pick up that strong of a signal from a satellite without a dish type antenna.  I have some hands on experience in installing and aiming a directv satellite dish and I assure you, it better be aimed at the correct spot or you ain't going to get a signal good enough to use.  Very hard to aim and capture the signal.

   If this was from one of Charlie's satellites, he was probably using a "Spot Beam" to cover a small area.

I have to wonder how much power he would have to use to get a strong enough signal on the ground that you could pick it up without much trouble.  You may have really stumbled into something that was previously unknown to the general public.

 

I would not think that any of Charlie's older satellites would have been equipped to broadcast on the H Block unless Charlie had bought a satellite from another bankrupt satellite company that had previously been allowed to transmit on those frequencies. Since Charlie only recently acquired the H Block, he would not have had time to build and launch a new satellite equipped to use the H Block.

-90dBm is not a very strong signal. But it was consistent. At best it was -86dBm. At worst, -93dBm. I'd love to hear another explanation. There were no towers of any type in most of the area, and this is pretty high frequency spectrum. It's not coming from a mountain top or boomers. There would have been a lot of variability. Also, the signal just magically appeared within the past 2-3 weeks. Wasn't there in Mid July.

Yes, but at the Earth's surface, GPS signals are typically on the order of -150 dBm RSSI.

You were probably picking up signal from Dish's adjacent S-Band 2000-2020MHz bleeding over. But as far as I know that is supposed to be an uplink and not a downlink. Is Dish testing it as a downlink? They have not filed their application to turn it into a downlink yet, as far as I know.

OK AJ, if the GPS signals are typically -150 RSSI, do you know what the signal levels are on a Directv or Dish satellite?  Why does it take a carefully aimed dish at home to pick up those signals while a GPS can pick up a -150 with a cheapie built in antenna?  Is the GPS satellite transmitting at a much higher power?

GPS signals are very low data rate CDMA.  So, the spreading gain between the data rate and the signal bandwidth is massive.  DBS signals do not have that advantage.
