Will they ever give up?

This is turning into an epic soap opera... When will LightSquared realize they can use their band for the original purpose (Sat->Ground communications) and not re-purpose it... There is a reason these bands are carefully carved out by ITU and FCC....

Oh come on

Oh I see instead of you fixing your system you expect the legacy users to fix theirs'. I am sorry but it is up to you to fix YOUR! system and if you can't go away.

PCTEL antenna 1

PCTEL antenna 2

PCTEL antenna 3

"PCTEL has developed an antenna that will allow existing high precision users to retrofit their GPS devices to make them compatible with LightSquared's network. This antenna provides high precision GPS users with another in a series of solutions to make their equipment LightSquared-compatible."

Retrofit my A$$, OK LightSquared so you will pay off all of the big boys, trucking companies, farm tractor navigation systems, and any other large GPS user to install these high Q antennas but the average Joe, back country Ranger, Search and Rescue person with the pocket Garmin, Tom-Tom car navigation system, or any other portable GPS receiver is screwed.

There are plenty of high precession GPS receivers that have the receiver and antenna integrated into the same housing. This won't work for them...

Exactly right, The antennas shown are huge by comparison and not designed for portable use. Again if you have a hand held GPS device you are screwed.

Why is this a problem? How many technology advances over the years has caused end users to upgrade or be left behind? Heck, just look at the analog / digital television swap of a few years ago. When new software comes out do you get pissed when you need to upgrade your machine to run it? Should all technology advances stop where they are at this point?

Re: Oh come on

There's nothing wrong with LightSquared's system to fix. It's the broken GPS hardware whose manufacturers were too cheap to build them right in the first place. Why should LightSquared have to pay the GPS companies to use their rightfully licensed spectrum?

That is not true. Lightsquared got bad advice. Spectrum does not have walls; adjacent bands have to be compatible. Any kid with a radio merit badge could have told them that. Bad advice. Tsk tsk. Caveat emptor.

You can't be for real. We're not talking a technology advance. We're talking about using the same technology others have deployed in a swath of spectrum never intended for this purpose and hugely impacts public interests. They bought spectrum intended for sat to ground communication and are not happy they are stuck with that.

Re: Oh come on

Broken GPS hardware, please, this broken GPS hardware was built with FCC type approval. You can feed some people this BS but it does not work with somebody who knows how the Type approval process works. So you are saying 10 years ago the manufacturers of GPS equipment should have consulted the Tarot cards to find out is somebody like LightSquared was going to appear. Don't heap blame on current GPS equipment providers, blame the idiots at the FCC for letting LightSquared get their foot in the door.

That is so much garbage it's hard to explain how bad it is. GPS band interference isn't an advancement, it's regress. Future devices will depend on the GPS band to advance into better devices, so Lightsquared interference in the GPS band will cause REGRESS and IMPEDE ADVANCEMENT. Needing to get more expensive equipment to have inferior service for something that was working PERFECTLY WELL BEFORE THE INTERFERENCE is not an UPGRADE; it is a DOWNGRADE.

Our politicians are so dirty I will not be at all surprised if our only remedy is taking down the actual ground transmitter sites by hand. Eventually their colocated peers will be so afraid of collateral damage, they won't allow colocation, and eventually Lightsquared will loose their margins and go bust. It may come to pass. We can all hope we don't have to go there, but just look at how far this atrocity has gotten.

Re: Total Bovine Scatology

I see it as an upgrade if their mobile broadband will be as good as they say AND it will cover the many areas they claim. As the OP stated.they seem t be willing to work with the industries to get their equipment working so that leaves the end users left to decide how they want to proceed with their own equipment. You can either upgrade or don't, just like everything else over the years that has been altered.

Yeah, actually, there is. It's broken in concept and cannot reasonably be fixed.

Because, for the umpteenth time, they're trying to use "their rightfully licensed spectrum" in a manner for which it was never intended. If they were using it in the manner for which it was intended, there'd probably be no problem.

The fact that LightSquared keeps coming up with one-solution-after the other ought to be a clue as to the likely efficacy of their "solutions."

Except this isn't a "technology advance." This is mitigation, and probably poor mitigation, at that, for an induced problem that need not occur.

Btw: Our five-year-old, going on six, marine GPS is still fine, thankyouverymuch. It does not need to be replaced. It does not need hardware upgrades. All it needs is occasional chart updates and possibly occasional firmware updates. So I should go out and pay another $500 or $600 for a new marine GPS when the one I have is just fine, just so LightSquared and their investors can make money? Is that your argument? Really?

No, you should go out and buy another because (I assume) you want to continue having navigation on the water? Your choice though really.

How many folks had to buy digital adapters for their TVs JUST so the government could make money auctioning off the analog airwaves? Where were you on that one? Maybe the government will send out a voucher or two to help you out, I dont know.

This isnt just so Lightsquared can make cash, I look at it as much of the country will be getting decent data speeds where previously it was broadband black holes. It will give many areas another player for internet services. I am sure you have read this site long enough to see people whining about the evil monopoly and duopoly of their town and city.

Of course I am basing this off of what Ligthsquared is telling us about what they will be able to produce for a working network.

You mean digital TV, the standard which was developed in 1995 and it took until 2009 before NTSC was shutdown. It took many years to allow an orderly transition with new supporting products to become readily available and minimize as much disruptions as possible to the user community. LightSquared wants the same thing done in basically one year.

The problem is LightSquared's network will not improve rural coverage. They have only one satellite in orbit, which will offer minimal capacity and speeds. It's only used as a loophole in their lease agreements regarding terrestrial service. And they are are so cash-poor they need to utilize Sprint's existing infrastructure but even then, the only way they can raise that money is if they are given the go ahead to utilize their full 20 MHz, which in testing has already shown to render GPS useless in the vast majority in the USA.

And it is essentially about LightSquare making cash. Harbinger pad somewhere around $2 billion for the bankrupt company that leased this spectrum. This spectrum is only worth this much due to significant limitations imposed on it, especially in regards to terrestrial operations and interference with GPS and other users. If they are able to convert it to full terrestrial use, then the value shoots way up. Verizon paid about $10 billion for roughly an equivalent amount of spectrum in the last auction.

Guise do you know how doppler effect works...?

I think some folks here need a major physics fact check: RF spectrum, as some have mentioned, doesn't really have "walls" in between it. This is why spectrum is allocated with so-called "guard bands" on either side, to avoid interference. The spectrum LightSquare rushed out to buy so eagerly was bought ENTIRELY based on the assumption that it could be "converted" into terrestrial comms. However, the WHOLE REASON the government / FCC / ITU classified these frequencies for Earth-space communications was because signals from satellites in orbit are red-shifted by about 25 MHz when they reach the ground (that's the doppler effect in action... the same effect that lets cop ticket you for speeding, at least when they're paying attention). In LS's case, that would mean the frequencies they are using are within the (red-shifted) GPS signals on the ground. Also, guess what? The LS signal is a factor of roughly ten thousand to million times the strength of the incoming GPS signal from space, effectively wiping out GPS.
Essentially, LightSquare was poorly advised on the decision to pursue this route by some financial bozo who never bothered asking the folks at the engineering department whether or not this was even technically possible...
