Re: Ex Parte Notice: Terrestrial Use of the 2473-2495 MHz Band for Low-Power Mobile Broadband Networks – IB Docket No. 13-213

Dear Ms. Dortch:

On July 17, 2015, L. Barbee Ponder IV, General Counsel & Vice President, Regulatory Affairs, for Globalstar, Inc. (“Globalstar”), Dennis Roberson, President and Chief Executive Officer of Roberson and Associates, LLC, Regina M. Keeney and Steve Berman of Lawler, Metzger, Keeney & Logan, LLC, and I met separately with Commissioner Jessica Rosenworcel and Jennifer Thompson, Special Advisor to Commissioner Rosenworcel; Brendan Carr, Legal Advisor to Commissioner Ajit Pai; and Erin McGrath, Legal Advisor to Commissioner Michael O’Rielly. At these meetings, we urged the Commission to adopt its proposed rules in the above-captioned proceeding. These rules would both maintain Globalstar’s licensed Mobile Satellite Service (“MSS”) operations and permit Globalstar to provide low-power terrestrial mobile broadband service (or Terrestrial Low Power Service (“TLPS”)) using its licensed MSS spectrum and adjacent unlicensed 2.4 GHz spectrum. We provided Commissioner Rosenworcel, Ms. Thompson, Mr. Carr, and Ms. McGrath with the attached slide presentation.

As we described in these meetings, Globalstar is first and foremost a satellite company and is committed to the future success of its MSS business. Over the past few years, Globalstar has invested more than $1 billion in an entirely new satellite constellation and second-generation ground infrastructure. Globalstar plays an important public safety role, serves traditional enterprise segments, and has a growing and innovative suite of consumer products. Since this proceeding began in 2013, Globalstar’s SPOT personal tracking devices have been used to initiate over 1600 life-saving rescues, including 63 rescues during June 2015. Globalstar’s largest single customer for SPOT is the U.S. government.

Ms. Marlene DortchJuly 21, 2015Page 2

We explained in our meetings that Globalstar wants to extend its innovative approach to the terrestrial mobile broadband marketplace through the use of a combination of licensed and unlicensed spectrum. Globalstar recognizes the critical benefits of unlicensed services to the wireless ecosystem and the U.S. economy more generally, as those operations promote innovation, experimentation, and the development of new applications. We emphasized that, rather than having a detrimental impact, TLPS on IEEE Channel 14 will enhance existing unlicensed Wi-Fi services in the 2.4 GHz band in a number of different ways.

As Globalstar has described in this proceeding, TLPS operations on Channel 14 are consistent with the IEEE 802.11 protocol and do not overlap with the nearest Wi-Fi operations on Wi-Fi Channel 11. By enabling consumers to spread their wireless broadband usage over four rather than just three channels, TLPS will help relieve worsening congestion in the 2.4 GHz band. TLPS will thereby improve the experience of consumers using Wi-Fi hotspots around the country. Whatever hypothetical situation is assumed – twenty students in a classroom; thirty-five patrons at a coffee shop; one hundred travelers waiting in an airport terminal – all of those users will receive the benefits of increased broadband capacity across the 2.4 GHz band, whether or not they individually utilize TLPS. These students, customers, and travelers will enjoy faster data rates and a higher quality of service.

At these meetings, we pointed out that Globalstar and its partners will not operate TLPS as a standalone, one-channel system. The use of Channel 14 will be integrated into a wireless network that uses other publicly available unlicensed spectrum, including Wi-Fi Channels 1, 6 and 11 in the 2.4 GHz ISM band. Globalstar has no desire or competitive reason to degrade these Wi-Fi channels or other unlicensed spectrum, since such degradation would undercut its own terrestrial broadband offerings at 2.4 GHz.

The significant consumer benefits of TLPS were shown during a March 2015 demonstration at the FCC’s Technology Experience Center (“TEC”). At the request of the Commission’s Office of Engineering & Technology, Globalstar and other parties conducted this demonstration to consider the compatibility of TLPS with other unlicensed services. The activation of TLPS on non-overlapping Channel 14 yielded an approximately forty percentincrease in aggregate measured data throughput across the 2.4 GHz 802.11-capable spectrum.TLPS transmissions had no negative impact on the data throughput on Wi-Fi Channel 11 or any other 802.11 Wi-Fi channel.1

We also explained at our meetings how Globalstar measured this substantial increase in data throughput. First, Globalstar’s representatives took a baseline measurement of access point

1 In contrast, the results of the CableLabs demonstration at the FCC should be disregarded. In the CableLabs demonstration, TLPS Channel 14 access points were placed only a few feet from other access points and client devices. This “methodology” was designed to generate a negative impact on Channel 11. The enormous consumer benefits of a fourth non-overlapping 802.11 channel far outweigh the alleged harms seen in CableLabs’ contrived, far-fetched scenario.

Ms. Marlene DortchJuly 21, 2015Page 3

throughput on each of the four non-overlapping IEEE channels (Channels 1, 6, 11 and 14). Second, Globalstar measured the aggregate throughput on Wi-Fi Channels 1, 6 and 11 operating simultaneously with a total of twelve client devices (four per channel). Then, Globalstar activated a TLPS access point and shifted three client devices to Channel 14, such that all fourchannels were used by three clients each. Measured aggregate throughput increased by approximately forty percent. The demonstration at the FCC also showed that, if a fourth access point operated instead on one of the Wi-Fi channels already in use (in this case Channel 6), aggregate data throughput did not increase due to the overlapping nature of the Channel 6 access point. This result demonstrates that schools and other institutions will not be able to increase broadband throughput at 2.4 GHz merely by investing in additional access points. TLPS access points on Channel 14, however, will achieve that goal.

Below, we provide an image of the radiofrequency spectrum “waterfall” that was displayed during the demonstration at the FCC, showing the four non-overlapping 802.11channels operating independently. We also provide a graph showing the relative throughput achieved under the different scenarios demonstrated at the FCC.

At the meetings, we indicated that the TEC demonstration results are being confirmed by real-world TLPS deployments under Globalstar’s experimental authorizations. These deployments are utilizing prototype TLPS access points manufactured by Ruckus and client devices from HTC, Microsoft, and Apple that were upgraded to operate on Channel 14 or were able to operate on Channel 14 “out of the box” with no changes necessary.

Ms. Marlene DortchJuly 21, 2015Page 4

We also emphasized that TLPS will be a managed service with networked access points that will be individually controlled through a carrier-grade network operating system (“NOS”) analogous to the systems used to manage pico- and femto-cellular infrastructure. With this NOS, Globalstar will be able to terminate specific access point transmissions, reduce access point power, or shift access points to another 802.11 channel in a given environment to prevent or respond to interference should it be alleged, or to help determine the actual cause of claimed interference.

Finally, we reiterated that, unlike other spectrum initiatives that will take years if not a decade to benefit consumers, TLPS offers immediate relief from broadband congestion and provides substantial consumer benefits anywhere it is deployed. These benefits are beginning to be experienced by consumers who are using all four non-overlapping 802.11 channels in real-world deployments. Globalstar will provide additional information regarding these TLPS deployments in the near future.

Pursuant to section 1.1206(b)(2) of the Commission’s rules, 47 C.F.R. § 1.1206(b)(2), this ex parte notification and the attached presentation are being filed electronically for inclusion in the public record of the above-referenced proceeding.

Respectfully submitted,

/s/ James Monroe IIIJames Monroe IIIGlobalstar, Inc.
