4 edits | High flying blimps may be alternative to DirecTV High flying blimps may be alternative to DirecTV's internet product. The US military uses balloons/blimps in Iraq and Afghanistan for communications and surveillance. »www.boston.com/news/nation/washi···_blimps/
Industry has been examining something similar in the US for wireless communications and internet access.
»www.apcmag.com/apc/v3.nsf/0/6C5D···00120D7A
But that’s not to say dreams of mega-speed Web downloads are over. Challenging Proteus for sheer audacity is the Stratellite, a giant airship that uses solar powered engines to sit at about 65,000ft, beaming data over a radius of about 77,700 square kilometres — think blimp meets mobile phone tower.
The Stratellite, which has been developed by a company called Sanswire, is 74.6m long, 44.2m high, and contains nearly 37 million litres of gas. Made of Kevlar, the dirigible is powered by electric motors and held in a position determined by six GPS units. In addition to Internet data, it can be fitted for mobile phone transmission, paging, fixed wireless telephony and high definition TV broadcasts. The downside is that the Stratellite can only sustain 18 months in the air without repairs.
It’s also cumbersome, but the blimp’s advantage over satellites is that it sits much lower to the ground, so it theoretically doesn’t suffer from the same data lag problems. --

Problem with such technology though is it can only work in perfect weather... how many places is that true??? And even here where much of the year it is, though often to windy when clear... I doubt they are up more than about 50% of the time and mostly daylight hours where they can observe them and low flying planes can see them.

| DTV should focus on HDTV and lowering prices They could easily sqeeze competetors like comcast into a pinch if they added some more value to their service like a free tivo with 2 year signup or something like that, and stopped charging for extra recievers. Latency and satellite will always be a problem, you are talking 26,000 miles round trip.

It's actually 22,000 miles one way, and 44,000 miles round trip. It takes about 250 milliseconds for a round trip, so considering the fact that the signal has to make two round trips for Internet access, the distance alone is adding 500 milliseconds. Then you have to include the time it takes for the data to get from the NOC to the server, and back. There's just no way of reducing the latency with geosynchronous satellites.
That being said, and me being a DirecTV customer, I was very glad to hear that they were re-purposing Spaceway to do HD.

| There are a lot of things I'd like DTV to do. Freeing up these satellites for more HDTV is a start. I believe they are launching two more satellites early next year and are planning on having 1500+ HD channels available.
I'd also like for them to turn on the USB ports on the DirecTivos and enable the HMO option. I've upgraded my main DirecTivo receiver in my living room to record 160 hours but would like to share the content with the DirecTivo receiver in the bedroom.
However, since DirecTV and Tivo seem to be on the way out when their contract ends, that may be wishful thinking. | |

| From a couple Tivo / DTV message boards, I have heard that Tivo will continue to be DTV's "premium" DVR for the fee, with something else with maybe no fee or a smaller fee as a standard option.
DTV would anger a ton of their customers if they cut ties with Tivo... including me.
Maybe DTV plans to finally upgrade to 4.0 (HMO support), charge more for the Tivo, but offer the standard DVR without service fees or something. I do think that stand alone Tivo service is more with HMO than without. Not sure on that though. | |

I'm pretty sure you can enable the USB ports on the DirecTivos w/a hack. I have a series1 which doesn't have USB, so I'm not positive though (had to add internal network card on mine  )
Anyway, once you enable the USB and get a USB network adapter, you can then extract and insert shows into either TiVo. I'm not sure if there's a way to "share" w/out the manual extraction/insertion process. (You can, however, stream programs directly off your TiVo to an xbox running XBMC...)

| SubSpace signals would cure the problem.
You could have a real-time telephone conversation with someone in our neighboring star-system using subspace technology.
Subspace signals travel many times faster than the speed of light, but subspace radio signals, even those highly focused and radially polarized will decay over time and even "surface" to become normal slower EM. Therefore a subspace relay will have to be set every 22.65 light years under optimal galactic conditions. Note that this is an approximation, subatomic particles, dark matter and high intensity gravity wells have been known to disrupt, deflect or even absorb subspace transmissions, therefore an average string-cell will be approximately twenty light years.
Scientists continue to conduct experiments with higher energy levels in an attempt to drive communications signals into "deeper" layers of subspace, where it is thought the signal will travel up to 80% farther prior to decay. | |

| the good and the bad about this Actually, I know people who are loosing their jobs over this decision. The idea of the program was to use Ka band which is lower latency then the current satellites using along with more data throughput. Sure latency wouldn't be that great, but still Ka is lower latency frequency.
In the end I am happy they are putting the bandwidth to use by carrying HD channels, now I just hope those on the project can find other jobs at Hughs or somewhere else. | |

I for one, feel bad for DirecTV only using these satellites for HDTV. Customers in rural areas need a choice of a broadband like service. Sure it's no DSL or Cable and there is always going to be horrible latency but the speeds should be improved...even more so the slower than dialup uploads. Thankfully WildBlue is coming out but until consumers actually start using it then it is still just a hype. I would like more HDTV channels just like the next person I just think it should be shared for internet access as well.

| Sat great for rural areas, but...
Sat is great for rural customers, but I get the feeling that DTV didn't think they would get enough additional customers in the near future to make full use of this Sat in that way. I don't understand all the details, but it makes sense to me. I also don't know how many internet customers they have or if the number is growing or falling.
As DSL and Cable are brought to more homes, those people in those areas with Sat internet are probably dropping it.
People living in Rural areas probably don't have jobs / lifestyles that require HSI. So, getting them to pay the price of Sat internet is probably not easy either.
Its great that it is available, and if I had no other option, I would sign up, but in areas where other choices are available, the technology just can't compete... unless the local cable company is a complete joke. | |

| Re: Sat great for rural areas, but... I currently use Direcway b/c it's my only option. Believe me, I would drop it in a heart beat if cable or DSL became available. And it's not like I live in never, never land either. There is cable 1 mile from my house on one side and 2 miles from my house on the other side. Both different companies. I fall into one of those cable "black holes" I guess. There is also a RT with my local telco (CenturyTel) 2 miles from my house; right where the cable ends too....how ironic. If CenturyTel would just install a DSLAM into that RT I could have DSL. And that same RT could serve approx. 100 houses. So why haven't they upgraded it for DSL??? Beats me. I think one reason there isn't any cable here is b/c I live right on the county line. One company ran cable all the way to the line(Adelphia), and the other which serves my county didn't(Time Warner). I just love the way they own the license for my area and just sit on it not upgrading a thing!:(

They want to charge me $25,000 to extend their service to
my home. Its not even particularly rural. DSL is not
available. I refuse to use Directway/Directpc/Starband
due to VPN over KU satellite slows down to dialup speed,
and the 500MB daily cap would slow me down to dialup speed
23 hours a day (I would use the 500MB cap in about an hour).
Thus, I have 3 phone lines to my house, 2 of them always

@adelphia.net
| mglunt,
Believe it or not, most rural users are looking for HSI too. They're creating their own jobs via the Internet; marketing hand-made products, working as resellers, working as contract medical transcribers, etc. We should know, that's what we and many of our neighbors are doing.
We're fortunate to live on the major road that the cable system has strung it's cable along and can get cable Internet. Others not as fortunate are searching for other options. Many are really stuck with satellite. The rural phone carriers have not had their feet held to the fire by regulators and are extremely slow investing money in improving their systems, so forget about seeing DSL anytime soon. (When we left the east coast, we found it interesting that rural telephone carriers seem to add more charges to their bills than most carriers that serve suburban and urban markets. We're not sure where that extra money goes--it doesn't seem to be spent on equipment.) | |

But short of changing the laws of physics NO increase in capacity is going to substantially reduce latency.

Not feeling like finding a link from Google, I have seen a map of underseas cables (mostly fiber now) and its really mind boggling how many there are now.... same way you can get a 500ms or less overseas internet connection from DSL or cable... none of it goes to satellite.
The only things that routinely do anymore are TV news remotes, because of the spot nature and high bandwidth ... and you notice if they are live, there is ALWAYS the 1 sec delay between any question and correspondent replying. Even if they are in the same area but being transmitted that way.

Yorkton, SK | Latency??? You do know that when you talk on a cell phone there is a good chance the latency is around 300-500 ms.. just call yourself from your cell to a landline and you will here the latency... So if thats the case then VOIP would not really suffer... | |

| Re: Latency??? Well except that with switching and added land (and VOIP netwoirk itself) delays its closer to a full second,
But if you can learn to treat it like a walkie talkie where you pause and don't intereupt it can still physically work.

| Quantum Entanglement anyone? Here is an interesting theory that could solve the problem

and another

And here is it being tested
We report the first experimental long distance demonstration of this fascinating aspect of quantum mechanics," said Nicolas Gisin, a physicist at the University of Geneva.
His team teleported qubits carried by photons—particles of light—of 0.05 inch (1.3mm) wavelength in one laboratory onto photons of 0.06 inch (1.55mm) wavelength in another laboratory 180 feet (55 meters) away along 1.2 miles (2 kilometers) of fiber optic wire.
In 1997 and again in 1998, scientists successfully demonstrated the concept of quantum teleportation by transferring two dimensional systems over short distances, such as from one side of a table to the next. Gisin and his team prove that the concept of quantum teleportation holds up at longer distances.

| More pains of the "huge footprint" Once again, I get to sound like a broken record:
These "huge footprint" solutions for BB do little more than waste frequencies--especially when considering denser, urban areas.
Yes, having a base station antenna which can cover some large number of square miles makes sense when you are trying to serve ranchers in Utah--but it makes no sense at all in any of our urban areas.
Satellite, as the ultimate "big footprint" can't even distinguish between covering ranches outside Green River, UT and Salt Lake City--much less Denver or Phoenix. When a satellite uses some portion of its capacity to handle a VoIP user's conversation, that capacity is wiped out for the entire satellite coverage area--about half or two-thirds of the US. What a waste.
There are wireless BB solutions of value--but they have footprints appropriate with the densities of the areas they will cover. Satellite has only one footprint, and it's huge.
The truly interesting question is whether top management at DirectTV knew and understood this before investing billions, or whether they were ignorant of the basic limitations of their product capacity.
