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:

Globalstar, Inc. (“Globalstar”) writes to inform the Commission of the results of a recent deployment of Terrestrial Low Power Service (“TLPS”) conducted by Roberson and Associates at a college campus in Chicago, Illinois over the summer.1 By adding an additional 22 MHz channel (TLPS Channel 14) to the campus’ 2.4 GHz Wi-Fi network, users experienced increased aggregate throughput in excess of 90%. Significantly, due to the ability of TLPS to relieve existing Wi-Fi congestion immediately, this near-doubling of network throughput after the introduction of TLPS allowed for an improved experience for all users regardless of whether they remained on Channels 1, 6 and 11 or were operating on Channel 14.

With this filing, Globalstar also provides additional information regarding the network operating system (“NOS”) that it commits to employ as part of any commercial offering of TLPS. Globalstar’s NOS will not only authenticate clients onto the TLPS network, but will also provide a platform for operators of licensed and unlicensed services to quickly provide notice to Globalstar of any claimed interference to their services. While Globalstar firmly believes that its TLPS offering will have no negative impact on any other licensed or unlicensed service, Globalstar commits to deploy a NOS that can quickly and efficiently provide remedial measures if necessary.

Globalstar also addresses questions about the potential future deployment of LTE-U in the 2.4 GHz band. Globalstar’s TLPS opportunity is based on the existing 1 See Globalstar Experimental License, Call Sign WH2XNQ (effective April 2, 2015).

IEEE 802.11 standard commonly referred to as “Wi-Fi.” Given the extraordinary benefits of TLPS that are available immediately to consumers through the use of an embedded ecosystem of hundreds of millions of 802.11 devices, as recently demonstrated in Chicago, Globalstar has no plans to deploy any LTE-U service in unlicensed spectrum. Moreover, Globalstar commits not to deploy LTE-U in the 2.4 GHz band until the Commission has otherwise allowed LTE-U deployment to proceed in unlicensed spectrum.

The Chicago TLPS deployment confirms the substantial consumer benefits available immediately to Wi-Fi users, as well as its compatibility with other unlicensed services.

Attached is a report from Roberson and Associates, LLC (“Roberson and Associates”), titled “Terrestrial Low Power Service (TLPS) Deployment and Summary Measurements,” that, together with the attached Declaration provided by Kenneth J. Zdunek, Ph.D., confirms the critical and fundamental consumer benefits of TLPS. By enabling consumers to spread their wireless broadband usage over four rather than just three channels in the 2.4 GHz band, TLPS will help relieve worsening congestion in the band and immediately improve the experience of consumers in any Wi-Fi-congested area of the United States. These benefits will be realized upon the Commission adopting its proposed rules in the proceeding.2

Over the last three months, Roberson and Associates has conducted extensive measurements involving the concurrent operation of Channels 1, 6 and 11 and TLPS access points in a real-world environment.3 These measurements provide compelling support for the extraordinary benefits of TLPS. As the presentation indicates, in a deployment scenario where 6 out of 12 client devices were shifted from maximally utilized Channels 1, 6 and 11 to TLPS Channel 14, average throughput on a per client device basis for the network overall increased by 92.0%. Indeed, the total capacity of the 2 See Terrestrial Use of the 2473-2495 MHz Band for Low-Power Mobile Broadband Networks; Amendments to Rules for the Ancillary Terrestrial Component of Mobile Satellite Service Systems, Notice of Proposed Rulemaking, 28 FCC Rcd 15351 (2013).3 For this TLPS deployment on a Chicago, Illinois university campus, Roberson and Associates installed TLPS Ruckus access points configured to operate on Channel 14 using IEEE 802.11 technology. These TLPS access points were combined with the campus wireless network of Wi-Fi access points operating on Channels 1, 6 and 11. The TLPS client devices in this real-world deployment included a variety of tablets and smartphones manufactured by Apple, Google and Microsoft.

four-channel wireless network was maximized in this scenario, where half of the clients were migrated to Channel 14. Significantly, even the 6 client devices remaining on Wi-Fi Channels 1, 6 and 11 experienced an 89.5% increase in average downlink throughput. The integration of TLPS into this network allowed the offloading of traffic from Channels 1, 6 and 11, yielding faster data rates and a higher quality of service on those three Wi-Fi channels.

The Roberson and Associates report further demonstrates that there are no interference or compatibility issues between TLPS and Wi-Fi, nor with TLPS and Bluetooth operations in the 2.4 GHz ISM band. In addition, Roberson and Associates observed no perceptible effect on Channel 11 from substantial TLPS traffic streaming video applications (including Skype, Hulu and YouTube), and found no perceptible impact from TLPS operations on the operation of Bluetooth Standard and Low Energy devices, including heart monitors, speakers, mice and headsets.

Roberson and Associates’ presentation confirms the results of the demonstration at the Commission’s Technology Experience Center (“TEC”) five months ago. At the request of the Commission’s Office of Engineering & Technology (“OET”), Globalstar and other parties conducted this demonstration to evaluate the compatibility of TLPS with unlicensed services. At the FCC TEC, the activation of TLPS on non-overlapping Channel 14 yielded an approximately 40% increase in aggregate measured data throughput across the 2.4 GHz 802.11-capable spectrum when client devices were spread evenly over the four channels (3 client devices per channel).4 Meanwhile, TLPS transmissions had no negative impact on the data throughput on Wi-Fi Channel 11 or any other 802.11 Wi-Fi channels at the TEC while also having no negative impact on Bluetooth operations.5

4 As indicated above, during the Chicago deployment, Roberson and Associates moved additional client devices to Channel 14 in order to optimize the aggregate throughput for all 12 client devices operating across the four non-overlapping channels. This approach yielded an average increase of 92.0% per device when 6 of the 12 client devices were moved to Channel 14.5 See Letter from Regina M. Keeney, Counsel to Globalstar, Inc., to Marlene H.Dortch, Secretary, FCC, IB Docket No. 13-213 (Mar. 10, 2015) (attaching report of AT4 wireless, Inc. and Roberson and Associates, LLC, “Globalstar TLPS Operation Demonstration” (Mar. 6 and 9, 2015), and report of Michael Needham and Dr. Kenneth Zdunek, Roberson and Associates, LLC, “Bluetooth – TLPS Demonstrations at the FCC Technology Experience Center” (Mar. 10, 2015)).

Globalstar’s proposed Network Operating System and Interference Mitigation Procedures should alleviate any further concerns regarding TLPS.

While the record in this proceeding demonstrates that TLPS will not have any negative impact on unlicensed services, Globalstar nevertheless commits to employ interference detection and mitigation techniques. TLPS will be a managed service with networked access points that will be controlled through a carrier-grade network NOS analogous to the systems used to manage pico- and femto-cellular infrastructure. The NOS will be used not only to authenticate users on the TLPS network and ensure the security of TLPS operations, but also will be capable of mitigating harmful interference to other licensed or unlicensed services in the highly unlikely event that it occurs.

Globalstar has identified the existing Wi-Fi network management system of ViaSat, Inc. (“ViaSat”) as an ideal platform for its TLPS NOS. The attached presentation titled “TLPS NOS Management” provides further detail on how a TLPS NOS based on the ViaSat platform will be used to authenticate users and respond to complaints of harmful interference to licensed or unlicensed services. This management system will include a communications hotline for the reporting of harmful interference, and will provide the means for modifying TLPS emissions characteristics remotely, including reducing power levels, shifting to a different channel and powering off access points.

Globalstar will not deploy any LTE-U based service in unlicensed spectrum until the Commission has otherwise allowed such deployments to proceed.

Some commenters have expressed concern about potential Globalstar deployment of wireless broadband services based on an LTE-U wireless protocol. Globalstar responds that its TLPS offering is and has always been based on the IEEE 802.11 protocol, not LTE, given the immediate consumer benefits available from the 802.11ecosystem. Further, Globalstar has no objection to the FCC prohibiting it from deploying any LTE-U or LAA service which might raise concerns in the 2.4 GHz band until such time as the Commission has otherwise allowed the deployment of these services to proceed in unlicensed spectrum.

* * *

It has been almost two years since the Commission proposed rules to allow the deployment of TLPS and the record on this matter has been fully developed. Further delaying final action in this proceeding only postpones the enormous consumer benefits that TLPS will generate by helping to alleviate the worsening congestion in the heavily used 2.4 GHz band. Unlike other spectrum initiatives that will take years if not a decade

or more to benefit consumers, TLPS offers immediate relief from broadband congestion and provides substantial benefits anywhere it is deployed. Globalstar urges the Commission to adopt its proposed rules without further delay.

4. In the time period May – August 2015, engineers under my direction at Roberson and

Associates deployed wireless local area network access points using the IEEE 802.11n

protocol on Channel 14 at the student center at a university in Chicago at 3201 South

State Street. The deployment was conducted with the cooperation and assistance of the

university Office of Technology Services, which maintains and manages the campus Wi-

Fi network.

5. In this declaration I provide a statement regarding the facts and parameters of the

demonstration network. I provide a report titled “Terrestrial Low Power Service (TLPS)

Deployment and Summary Measurements,” describing the compatibility measurements

and demonstrations executed with the purpose of assessing the ability of Globalstar’s

proposed TLPS to successfully coexist with the existing Wi-Fi network in the student

center, specifically with devices utilizing the IEEE 802.11n protocol on Channel 11 in the

2.4 GHz Industrial, Scientific and Medical band.

6. It was also the purpose of the deployment and demonstration to assess the coexistence of

TLPS with Bluetooth devices and services.

7. An additional purpose of the deployment and demonstration was to assess the ability of

TLPS operating on IEEE Channel 14 to increase the user throughput and overall system

capacity of the existing Wi-Fi network.

Summary of Deployment

8. Three Ruckus model 7982 access points were configured to operate on Channel 14 using

the IEEE 802.11n protocol. Backhaul and connection to the internet was provided via the

existing campus backbone and gateway. The Channel 14 (TLPS) access points were

combined with the campus wireless network and devices manufactured by Meru

Networks operating on Channels 1, 6 and 11 using the IEEE 802.11n protocol.

9. The TLPS client devices consisted of Google Nexus 7 tablet computers, Microsoft

Surface Pro and Surface 3 tablet computers, an Apple iPhone4 and an Apple iPad.

10. The Bluetooth devices evaluated for compatibility included both Standard and Low

Energy devices: a heart rate monitor, stereo speaker, computer mice and headsets.

11. The deployment configuration and technical parameters of the TLPS access points,

including power levels, were coordinated with the local Broadcast Auxiliary Service

(BAS) licensees, WGN-TV and WBBM-TV, as required under the FCC experimental

license WH2XNQ.

12. In contrast to the demonstration of TLPS at the FCC conducted in March 2015, the

university deployment in Chicago was performed utilizing the pre-existing campus

backbone network and the existing access points operating on Channels 1, 6 and 11.

13. Additional details and photographs of the experimental deployment are included in the

attached report.

Summary of Results of Compatibility Measurements

14. Extensive measurements over a period of three months were performed with TLPS

devices and access points operating within, and simultaneously with, the existing campus

Wi-Fi network operating in the 2.4 GHz band. Several hundred individual measurement

trials were run under approximately twenty experimental scenarios. Multiple test runs for

each experimental scenario (typically 10 trials) were performed to obtain statistically

significant results.

15. In the university deployment, both the existing IEEE Channel 6 and TLPS operating on

Channel 14 are adjacent to existing IEEE Channel 11. The device throughput

measurements assessing the compatibility of TLPS with existing Channel 11 operations

demonstrated that TLPS has the same small quantitative impact as Channel 6 on Channel

11.

16. Regarding the demonstrations performed to assess any qualitative, user-perceptible

impact on Channel 11 operations, it was observed that TLPS had no user-detectable

effect on Channel 11 executing streaming video applications.

17. Regarding the measurements and demonstrations conducted to assess the impact of TLPS

operations on overall user and network throughput, it was found that the addition of

TLPS on IEEE Channel 14 significantly increased overall network and individual device

throughput levels. The quantitative levels of improvement are shown in the attached

report.

18. Regarding the demonstration scenarios executed with the Bluetooth devices to assess the

compatibility of TLPS with Bluetooth, it was found that simultaneous operation of

wireless devices and access points on IEEE Channels 1, 6, 11 and TLPS on Channel 14

produced no user perceivable impact to Bluetooth devices.

19. Full details of the measurements and results regarding the impact of TLPS on IEEE

Channel 11, the impact of TLPS on overall wireless network capacity, and the impact of

TLPS on Bluetooth, are provided in the attached report.

Conclusions

20. The measurements and demonstrations performed show that TLPS is fully compatible

with 2.4 GHz unlicensed operations. No harmful interference or compatibility issues

were identified.

21. No user-perceptible impact on Channel 11 streaming video services, or on Bluetooth

Standard or Low Energy devices was observed during operation representative of real-

world conditions.

22. It can be concluded that TLPS provides significant overall capacity gains and materially

increases the throughput experience of all users on the network. Specifically:

! As greater numbers of users are moved from existing Wi-Fi Channels 1, 6 and 11, to

TLPS on Channel 14, congestion is eased on those Wi-Fi channels. This allows for a

significant improvement to the user experience for those users remaining on the

existing Wi-Fi channels, as well as those users moved to Channel 14.

! As shown in the attached report, if 3 users on a network with 12 active clients

altogether are moved to Channel 14, the average throughput experienced by each user

increases 56%.

! Also shown in the attached report, for the deployment scenario where 6 out of 12

client devices are shifted from maximally utilized IEEE Channels 1, 6 and 11 to

TLPS Channel 14, the average throughput, on a per client device basis for the

network overall, increases by 92%.

! The uncongested nature of Channel 14 allows the channel to handle a traffic load

approximating that of the existing Channels 1, 6 and 11 combined.

Pursuant to 28 U.S.C. § 1746, I declare under penalty of perjury under the laws of the United

States that the foregoing is true and correct to the best of my knowledge, information and belief.

Executed this 9th day of September 2015.
