Thanks, Rebecca. As you just heard, we're pleased with the continued positive financial momentum we began in the fourth quarter of last year, and we are encouraged with our financial progress.
These past 2 quarters demonstrated turnaround for our business and are a result of restructuring the operations which we began last year. As explained in March, with increased discipline in sales, marketing, product development plus the new constellation offering improved coverage and the return of the MSS industry in this highest-quality voice service, we're laying a strong foundation for future growth in the business. Globalstar continues to make the necessary investments in the operational improvements to best realize the significant opportunities that lie ahead. And we continue our focus on increasing revenue and profitability in 2012. We also continue to expect these trends will be manifest more in the second half of the year.
Today, we're just one launch away from restoring full coverage. Throughout the quarter, we continued to deploy new satellites, further improving our call success rate. The company anticipates returning to sustained duplex revenue growth later this year as additional second-generation satellites are placed into service.
Currently, our customers in key markets are experiencing increased connection rates. These rates are expected to improve further in the near term as 4 new second-generation satellites are scheduled to be placed into service over the next couple of months.
With these additional satellites in operation, call connection rates are expected to increase to between 80% and 90% in our key markets by August. Further increases are projected as additional satellites are placed in service throughout the remainder of the year. The increase in the service levels are expected to drive both usage and new subscriber additions.
We remain on track for our fourth launch in the second half of this year. With this launch, we expect to return to the level of service our customers enjoyed just a few years ago. We will update you with further information once our launch date is finalized.
Also, the momentum we are reaching we had previously discussed has had no significant impact on service levels, and none of the satellites launched in late December has shown any indication of being affected.
We continue to work diligently with our satellite manufacturer and others on the development of the software patch designed to correct the problem. Since our last call, further development simulations in California and France validated the proposed fix, and we expect to implement the software upgrade in 2 phases beginning as early as June.
We reiterate, once installed, we expect that all of our new satellites will successfully complete their 15-year mission.
I know many of you remain keenly interested in the status of the commercial arbitration with Thales regarding our rights to order additional satellites under our contract. Since our last call, the arbitration panel has closed the record in the proceeding, and we anticipate the ruling at any time now. We look forward to putting this dispute behind us and continuing our longstanding relationship with Thales.
As Rebecca stated earlier, service revenue from our SPOT devices increased by approximately 27% in the first quarter compared to the same period in 2011. Due to the continued success of SPOT and related consumer products, Globalstar has received orders to ship a total of 370,000 SPOT devices to our retail points of distribution worldwide. These award-winning devices have been responsible for the initiation of more than 1,800 rescues around the globe, 100 more than at the end of 2011.
Also, as Rebecca pointed out, during the quarter, we announced important and positive changes to the COFACE facility, and we're pleased with the amendment and remain grateful for the consideration shown by all parties involved for recognizing the need for this amendment while we complete the launch of the second-generation constellation.
I'd like to update you on our space-based next-gen air traffic management initiative with ADS-B Technologies. We initially discussed this on our last earnings call.
During the first quarter, ADS-B continued development of its next-generation air traffic surveillance product. This solution uses the Globalstar system to provide realtime aircraft surveillance data from remote areas where a conventional line of sight connection to a terrestrial ADS-B ground station is not possible or impractical.
ADS-B Tech and Globalstar have been working on this solution for almost 2 years. In April, ADS-B successfully tested the capability of the system in a second series of demonstration flights, verifying the feasibility of space-based air-traffic surveillance using Globalstar's LEO constellation. We're very excited about these recent test results, and they proved the technical feasibility of using the Globalstar system. In other words, this is not a "pie in the sky" idea that may be implemented many years from now. It's a proven concept using existing Globalstar satellites and ground infrastructure, with equipment newly installed in aircraft.
We are pleased to say that ADS-B solution is now gaining attention of the FAA, and are very excited about the global revenue opportunity that space-based aircraft management systems represent around the world.
Globalstar's unique bent-pipe architecture, in a network of ground stations, not only provides a low-cost solution but also is the only satellite network that can handle the amount of data required reliably and with no latency concerns.
We'll update you further regarding the initiatives during our next earnings call.
Shifting gears just a little bit, we spent the last few years inwardly focused on getting a new constellation built. But since the new year, and that constellation is largely completed, it probably makes sense to step back and think about the business opportunity that we can finally realize upon.
Here's the way we, as company management and significant shareholders, look at the future of Globalstar. Globalstar's at an inflection point now. We have a low-cost, second-generation satellite and ground infrastructure. It has the daily capacity to transmit 30 billion small messages, be those text messages, M2M transmissions or other small messages. It has the ability to transmit 19 million voice and data minutes. It's the industry's lowest-cost, best voice quality, and this system was built at only 10% to 15% of the first-generation network cost, allowing us to exploit many more opportunities profitably.
Globalstar's inflection point includes breakthrough mass market consumer products, like SPOT. And lastly, Globalstar controls a non-replicable 25 megahertz of global spectrum, with 19 megahertz of that authorized for terrestrial broadband use in the United States.
With this constellation, inexpensive MSS consumer market products and the spectrum, we have an enormous addressable market. We think of this market of Globalstar as 4 buckets. One, there are about 1 billion people who live beyond traditional wireless and wireline coverage. Amazingly, that wireless and wireline coverage covers only 25% of the landmass of the world. So there's 1 billion people that live beyond that. It's 1 billion people in the second bucket who either work or play beyond wireless coverage. There's a third bucket, which changes in terms of numbers annually, and that's, where connectivity fails, Globalstar shines. So whether it's a natural disaster or the people that service those natural disasters, Globalstar shines.
It's also effective in countries where known political repression or other situations like that exists and people can dial around in those countries the traditional wireless and wireline networks in them. Lastly, there's a bucket of a low-cost alternative to high-cost roaming at $0.10 a minute versus international roaming of $2 a minute. This is a $60 billion a year market by 2015 that we can penetrate.
And Globalstar has the network capacity to address these markets. [Indiscernible] Globalstar has just fungible capacity. If you think about it in terms of text messaging or small messaging, asset tracking and so forth, and if you think a normal user would use 20 messages per day, you can support 1.7 billion users on Globalstar's new network.
If you think about them as users using 50 minutes a month, you can support 11 million of those, or the standby users who average only 10 minutes a month, you can support 55 million users on this network.
So if you just take an average of remote and standby users, it's about 30 million users that we can support on the network. And if you assume just a marginal ARPU of only $10, instead of what we expect long term, we have a $3.5 billion business with an 80% EBITDA margin.
So the question becomes simply sales and marketing. This is how we do it now, and this is how we'll do it going forward. And at the top, you'll see a list of some of the participants in our 10,000 points of retail distribution. But at 10,000 points, it's clearly not enough to address the full market that we've described.
So going forward, we will work with domestic and international carriers to establish broader sales channels, whether it's Vodafone, China Mobile, America Movil, Deutsche Telekom or others, those companies offer Globalstar the opportunity to have a much, much broader reach and consume some of this capacity we talked about a moment ago.
There's a third bucket, and that third bucket is cooperation with technology companies who might want to have this capacity available to them in order to satisfy their individual product offerings, whether it is Apple or Dell, Microsoft or Google, all of these companies have a need to reach their customers in what the marketing advantage that comes from being able to provide service to their customers everywhere as opposed to something limited to the terrestrial networks.
With these 3 distinct distribution channels, we can fully utilize our capacity offering, expensive -- inexpensive, excuse me. Stop. With these 3 distinct distribution channels, we can fully utilize our capacity, offering inexpensive consumer products, something that, apparently, no other MSS company seems to want to go after.
To end the call today, I want to discuss spectrum. First, not all spectrum is created equal. Globalstar's is actually no exception. Noise and interference directly impact network capacity, if you're going to use spectrum terrestrially. This is why a small amount of low-noise spectrum can carry significantly more data than a much larger parcel of noise- and interference-limited spectrum. Globalstar's spectrum has extremely low noise and interference characteristics. As you can see on this 3D spectrograph, which shows the usable spectrum for terrestrial between roughly 300 and 3,000 megahertz, Globalstar's spectrum sits in uniquely quiet bands, assuring high throughput and making it very attractive for terrestrial wireless use.
How does that spectrum get used to fulfill the needs of a terrestrial wireless company? [indiscernible] the need for more spectrum and the impending spectrum deficit. The FCC is doing its best to add more to the inventory for terrestrial wireless use and with some substantial success. And if you look at this chart that the FCC has set on the broadband plan is we have 547 megahertz of spectrum that's available today. And by 2015, given the rapid increase in data usage, we will need 847 megahertz.
And this bridge shows you how you get to 847 from 547. Unfortunately, the 120 megahertz, which is designated from the broadcasters, is not going to come in in any reasonable period of time, and it will never appear as 120 megahertz. The WCS spectrum of 20 megahertz has come into the inventory, but the federal government has pushed back on the AWS's 60 megahertz allocation and has indicated that it could come in over the next 10 years but it would come in at a cost of $15 billion to $18 billion of relocation.
The D Block has been given to public safety, so it's not available. And that leaves MSS providers to fill the gap. LightSquared is in peril. DISH is going through the process now and will be approved shortly, and Globalstar is right behind that from regulatory process.
And as you're aware, the broadband plan has encouraged the use of this MSS spectrum to deliver terrestrial capacity.
In March, the FCC announced a notice to propose rulemaking regarding the use of the 2 gigahertz MSS spectrum transferred to DISH Network's. In this, the FCC has proposed to eliminate virtually all of the gating criteria for the use of the spectrum, which permits it to be used exactly like all other terrestrial spectrum.
They also stated in the NPRM that they would address Globalstar's spectrum once DISH is finished. In our conversations with the FCC, they have told us that they plan to use DISH as a model for Globalstar's NPRM. Ultimately, we expect the FCC to grant all MSS providers with additional flexibility to utilize our spectrum terrestrially to better serve the customers with new services and to treat all MSS providers similarly.
So in summary, Globalstar concluded the first quarter by continuing the positive momentum in growth and profitability that we began last year. We continued to lay the products and business operations foundation necessary to grow our subscribe base and technology offerings with an increased concentration on driving revenue and profitability in 2012 and beyond. And we plan to creatively deal with the spectrum opportunity before us this year.
Thank you all for your time, and I look forward to speaking to you again in August. Tony, Rebecca and I are now available to answer your questions.
