To  Whom  It  May  Concern:  

        Google  Inc.  (Google),  pursuant  to  5  U.S.C.  §  552  and  Sections  0.457  and  0.459  of  the  
Commission's  Rules,  47  C.F.R.  §§  0.457,  0.459,  hereby  requests  that  certain  information  
complementary  to  its  above-­referenced  application  to  modify  its  Experimental  Radio  Service  
License  for  call  sign  WH2XNF  (File  No.  0722-­EX-­PL-­2014)  (Modification  Application)  be  
treated  as  confidential  and  not  subject  to  public  inspection.    The  designated  information  
constitutes  confidential  and  proprietary  information  that,  if  subject  to  public  disclosure,  would  
cause  significant  commercial,  economic,  and  competitive  harm.    As  described  below,  
Google’s  request  satisfies  the  standards  for  grant  of  such  requests  set  forth  in  Sections  0.457  
and  0.459  of  the  Commission’s  Rules.  

         In  accordance  with  Section  0.459(b)  and  in  support  of  this  request,  Google  provides  
the  following  information:  
  
  
1.       Identification  of  the  Information  for  Which  Confidential  Treatment  is  Sought:  
  
         Google’s  request  for  confidential  treatment  is  limited  to  information  that  has  been  
         redacted  from  the  Modification  Application  and  Exhibits  A  and  B.    Google  does  not  
         seek  to  withhold  from  public  inspection  information  in  the  Modification  Application  and  
         associated  exhibits  necessary  for  interference  mitigation,  including  applicant  name,  
         contact  information,  test  location,  frequency,  output  power,  effective  radiated  power,  
         emission  characteristics,  and  modulation.  
  
         Exhibit  A  -­  Narrative  Statement:  
           
         Google  requests  confidential  treatment  of  the  following  underlined  text  from  Exhibit  A  
         that  contain  confidential  and  proprietary  information  regarding  the  proposed  
         tests/experiments:  
           
                     Consistent  with  the  standards  set  forth  in  Section  5.63  of  the  Federal

              call  sign  WH2XNF  (File  No.  0722-­EX-­PL-­2014).    Below,  Google  outlines  the  
              reasons  that  the  modification  should  be  granted  expeditiously.     
           
                       The  requested  modification  is  needed  to  expand  testing  and  measuring  of  
              propagation  losses  in  the  3.5  GHz  band,  a  band  which  the  Commission  is  now  
              assessing  for  broader  commercial  use.    The  specific  modifications  requested  
              include  additional  emission  designators  [REDACTED].    [REDACTED],  under  
              conditions  that  are  consistent  with  the  Commission’s  proposed  Part  96  rules.1     The  
              requested  modification  also  includes  a  greater  antenna  height  limit  at  the  Mountain  
              View,  California,  site  [REDACTED].    As  discussed  further  below,  operations  under  
              the  modified  license  will  continue  to  protect  incumbent  operators  from  interference.  
                         
                       No  modifications  of  the  license  terms  are  requested  at  the  Arlington  and  
              Reston,  Virginia,  locations.    Deployments  using  the  modified  license  terms  will  be  
              limited  to  the  Mountain  View,  California,  site.     
           
                      Propagation  testing:  During  propagation  testing,  [REDACTED]  continuous  
                      waveform  (CW)  signal  will  be  transmitted.    
                        
                      SAS  testing:  During  testing,  [REDACTED],  serving  as  prototypical  Citizen  
                      Broadband  Radio  Service  Devices  (CBSDs),  will  be  deployed,  and  
                      [REDACTED].    A  full  list  of  potential  equipment  manufacturers  is  set  forth  in  
                      Exhibit  B.    [REDACTED].    [REDACTED].    The  conducted  power  generated  
                      by  each  transmitter  will  be  limited  to  3  Watts.    A  variety  of  antennas  will  be  
                      used,  ranging  from  high-­gain  (16  dBi,  90  deg  beamwidth)  [REDACTED]  to  
                      low-­gain  (-­4  dBi)  [REDACTED].  The  maximum  EIRP  [REDACTED]  will  be  51  
                      dBm,  which  does  not  reflect  a  change  from  the  existing  experimental  license.  
                      The  antennas  will  generally  be  located  at  a  height  ranging  from  2  meters  
                      (ground  level)  to  8  meters  (atop  a  single-­story  building),  but  Google  is  
                      requesting  authorization  for  heights  up  to  23  meters  at  the  Mountain  View  
                      location  [REDACTED].    All  installations  in  Mountain  View  [REDACTED],  and  
                      antennas  that  are  not  at  ground  level  will  be  mounted  on  existing  buildings  
                      and  will  not  extend  more  than  1.8  meters  above  those  buildings.  
           
                     Grant  of  this  modification  will  not  adversely  impact  any  authorized  user  of  RF  
              spectrum  for  the  reasons  stated  below.

                            authorized  to  receive  on  these  frequencies  in  the  United  States,  and  that  
                            reception  on  these  frequencies  is  limited  to  the  Netherlands  and  Italy.  

                       ● Land  Mobile  Radiolocation  Licensees:  Based  on  a  query  of  the  FCC’s  
                         universal  licensing  system,  there  are  three  active  land  mobile  
                         radiolocation  licenses  in  the  3550-­3575  MHz  band.    Call  signs  
                         WQLW310  and  WQLX454  are  limited  to  a  radius  of  113  kilometers  
                         around  a  centerpoint  near  Boulder,  Colorado.    Because  they  are  far  
                         removed  from  the  Mountain  View  test  site,  there  is  no  risk  of  harmful  
                         interference  to  these  operations.    The  third  license,  call  sign  WQHK852,  
                         is  a  nationwide  license  covering  a  total  of  two  units.  There  are  no  specific  
                         locations  associated  with  the  license.    Google  e-­mailed  the  licensee,  
                         Mobile  Data  Solutions  Ltd.,  on  September  30,  2014,  to  request  any  
                         additional  information  necessary  to  ensure  that  harmful  interference  is  
                         avoided.    To  date,  Google  has  received  no  response.    Google  continues  
                         to  be  prepared  to  coordinate  as  necessary  with  Mobile  Data  Solutions  
                         Ltd.  to  avoid  harmful  interference  to  call  sign  WQHK852.  

                       ● Federal  Operations:  The  principal  federal  incumbent  in  this  band  is  the  
                         Department  of  Defense,  which  uses  the  band  for  radars  aboard  Navy  
                         ships  and  at  two  land-­based  locations.  

                            According  to  ITU  Recommendation  M.1465  and  a  2010  report  by  the  
                            National  Telecommunications  and  Information  Administration,  these  
                            radars  can  tolerate  a  maximum  interfering  signal  level  of  -­115  dBm,  
                            assuming  a  -­10  dB  interference-­to-­noise  ratio,  a  0  dB  noise  figure  (which  
                            corresponds  to  a  -­105  dBm  noise  level),  and  an  effective  receive  
                            bandwidth  of  8  MHz.2     
                              
                            The  Navy’s  Southern  California  Operations  Area  is  32  kilometers  away  
                            from  the  Mountain  View  test  site,  but  separated  by  a  mountain  range.  
                            Using  the  terrain-­based  Longley-­Rice  propagation  model  to  determine  
                            the  propagation  loss  associated  with  proposed  transmissions  from  the  
                            Mountain  View  test  site  to  the  Navy’s  site,  the  experimental  signal  will  be  
                            at  least  30  dB  below  the  radar’s  interference  objective.    This  analysis

                      accounts  for  the  fact  that  the  antennas  may  be  as  high  as  23  meters  
                      above  ground  level  and  could  point  in  any  direction  in  the  horizontal  
                      plane.     

                      Nevertheless,  Google  is  prepared  to  coordinate  as  necessary  with  the

         The  information  requested  to  be  kept  confidential  has  significant  commercial  value.  
         The  exhibits  supporting  the  Modification  Application  discuss  tests/experiments  that  
         include  trade  secret  information.    The  Commission  has  clarified  that  confidential

         treatment  should  be  afforded  to  trade  secrets.   Google’s  tests/experiments  and  
         proprietary  wireless  applications  using  particular  radio  frequency  equipment  represent  
         a  “secret  commercially  valuable  plan”  within  the  meaning  of  a  trade  secret  as  
         recognized  by  the  Commission.

                                                                                   File  No.  0004-­EX-­ML-­2015  
  
4.        Explanation  of  the  degree  to  which  the  information  concerns  a  service  that  is  
          competitive.    
  
          The  services  and  technologies  that  are  the  subject  of  this  Modification  Application  
          have  not  yet  been  fully  developed  but  are  expected  to  lead  to  material  developments  
          in  markets  subject  to  competition  from  multiple  U.S.  and  non-­U.S.  third  parties.    
            
            
5.        Explanation  of  how  disclosure  of  the  information  could  result  in  substantial  
          competitive  harm.     
  
          The  technology  under  development  is  highly  sensitive  and  confidential  in  nature.    The  
          release  of  such  information  would  provide  valuable  insight  into  Google’s  technology  
          innovations  and  potential  business  plans  and  strategies.    Public  disclosure  would  
          jeopardize  the  value  of  the  technology  under  examination  by  enabling  others  to  utilize  
          Google’s  information  to  develop  similar  products  in  a  similar  time  frame.     
  
     6.   Identification  of  any  measures  taken  by  the  requesting  party  to  prevent  
          unauthorized  disclosure.  
  
          Google  has  taken  steps  to  keep  confidential  the  information  set  forth  in  the  confidential  
          exhibits  by  limiting  the  number  of  people  involved  in  the  tests/experiments  to  only  
          those  on  a  “need  to  know”  basis,  and  will  require  that  all  third  parties  involved  in  any  
          preliminary  analysis  execute  robust  nondisclosure  agreements.  
  
  
7.        Identification  of  whether  the  information  is  available  to  the  public  and  the  extent  
          of  any  previous  disclosures  of  the  information  to  any  third  parties.  
  
          The  information  contained  in  the  confidential  exhibits  is  not  available  to  the  public,  and  
          will  only  be  disclosed  to  third  parties  pursuant  to  the  restrictive  safeguards  described  
          above.  
            
          Google  voluntarily  provides  the  information  to  the  Commission  at  this  time  with  the  
          expectation  that  it  will  be  treated  confidentially  in  accordance  with  the  Commission's  
          rules.  See  Critical  Mass  Energy  Project  v.  Nuclear  Regulatory  Comm’n,  975  F.2d  871,  
          879  (D.C.  Cir.  1992)  (commercial  information  provided  on  a  voluntary  basis  “is  
          ‘confidential’  for  the  purpose  of  Freedom  of  Information  Act  (FOIA)  Exemption  4  if  it  is  
          of  a  kind  that  would  customarily  not  be  released  to  the  public  by  the  person  from  whom  
          it  was  obtained.”)

                                                                                                     Google  Inc.  
                                                                                   File  No.  0004-­EX-­ML-­2015  
  
8.        Justification  of  the  requested  period  of  confidentiality.    
  
          Google  expects  that  confidential  treatment  will  be  necessary  for  the  length  of  the  
          proposed  experiment  and  thereafter  in  order  to  protect  its  evolving  business  and  
          technology  strategies.  
  
  
9.        Any  other  information  that  would  be  useful  in  assessing  whether  this  request  
          should  be  submitted.  
       
          The  information  subject  to  this  request  for  confidentiality  should  not  be  made  available  
          for  public  disclosure  at  any  time.    There  is  nothing  material  that  public  review  of  this  
          information  would  add  to  the  Commission’s  analysis  of  Google’s  request  for  an  
          experimental  authorization.    
            
          Moreover,  public  disclosure  of  the  sensitive  information  in  the  confidential  exhibits  to  
          the  Modification  Application  after  the  Commission  has  ruled  on  the  Request  for  
          Confidentiality  is  not  necessary  for  the  Commission  to  fulfill  its  regulatory  
          responsibilities.     
            
          Consistent  with  47  C.F.R.  §  0.459(d)(l),  Google  requests  notification  if  release  of  the  
          information  subject  to  this  request  is  requested  pursuant  to  the  FOIA  or  otherwise,  so  
          that  Google  may  have  an  opportunity  to  oppose  grant  of  any  such  request.  
  
Sincerely  yours,

                                      EXHIBIT  A  –  NARRATIVE  STATEMENT  
                                                                  
          Consistent  with  the  standards  set  forth  in  Section  5.63  of  the  Federal  Communications  
Commission’s  (FCC’s  or  Commission’s)  Rules,  47  C.F.R.  §  5.63,  Google  Inc.  (Google)  seeks  
modification  its  Experimental  Radio  Service  License  for  call  sign  WH2XNF  (File  No.  
0722-­EX-­PL-­2014).    Below,  Google  outlines  the  reasons  that  the  modification  should  be  
granted  expeditiously.     
            
          The  requested  modification  is  needed  to  expand  testing  and  measuring  of  propagation  
losses  in  the  3.5  GHz  band,  a  band  which  the  Commission  is  now  assessing  for  broader  
commercial  use.    The  specific  modifications  requested  include  additional  emission  
designators  [REDACTED].    [REDACTED],  under  conditions  that  are  consistent  with  the  
Commission’s  proposed  Part  96  rules.1     The  requested  modification  also  includes  a  greater  
antenna  height  limit  at  the  Mountain  View,  California,  site  [REDACTED].    As  discussed  further  
below,  operations  under  the  modified  license  will  continue  to  protect  incumbent  operators  
from  interference.  
            
          No  modifications  of  the  license  terms  are  requested  at  the  Arlington  and  Reston,  
Virginia,  locations.    Deployments  using  the  modified  license  terms  will  be  limited  to  the  
Mountain  View,  California,  site.     
            
             Propagation  testing:  During  propagation  testing,  [REDACTED]  continuous  
             waveform  (CW)  signal  will  be  transmitted.    
            
             SAS  testing:  During  testing,  [REDACTED],  serving  as  prototypical  Citizen  
             Broadband  Radio  Service  Devices  (CBSDs),  will  be  deployed,  and  [REDACTED].    A  
             full  list  of  potential  equipment  manufacturers  is  set  forth  in  Exhibit  B.    [REDACTED].  
             [REDACTED].    The  conducted  power  generated  by  each  transmitter  will  be  limited  to  
             3  Watts.    A  variety  of  antennas  will  be  used,  ranging  from  high-­gain  (16  dBi,  90  deg  
             beamwidth)  [REDACTED]  to  low-­gain  (-­4  dBi)  [REDACTED].  The  maximum  EIRP  
             [REDACTED]  will  be  51  dBm,  which  does  not  reflect  a  change  from  the  existing  
             experimental  license.  The  antennas  will  generally  be  located  at  a  height  ranging  from  
             2  meters  (ground  level)  to  8  meters  (atop  a  single-­story  building),  but  Google  is  
             requesting  authorization  for  heights  up  to  23  meters  at  the  Mountain  View  location  
             [REDACTED].    All  installations  in  Mountain  View  [REDACTED],  and  antennas  that  
             are  not  at  ground  level  will  be  mounted  on  existing  buildings  and  will  not  extend  more  
             than  1.8  meters  above  those  buildings.  
            
          Grant  of  this  modification  will  not  adversely  impact  any  authorized  user  of  RF  spectrum  
for  the  reasons  stated  below.

         ● Fixed-­Satellite  Earth  Station  Licenses:  Based  on  a  query  of  the  FCC’s  IBFS  
           licensing  system,  there  are  no  active  or  pending  U.S.-­based  earth  station  licenses  
           in  the  3550-­3575  MHz  band.    A  search  of  current  licensees  for  the  3550-­3575  MHz  
           band  returns  one  result,  FCC  call  sign  E050348,  but  the  license  reveals  that  the  
           licensee  is  not  in  fact  authorized  to  receive  on  these  frequencies  in  the  United  
           States,  and  that  reception  on  these  frequencies  is  limited  to  the  Netherlands  and  
           Italy.  

         ● Land  Mobile  Radiolocation  Licensees:  Based  on  a  query  of  the  FCC’s  universal  
           licensing  system,  there  are  three  active  land  mobile  radiolocation  licenses  in  the  
           3550-­3575  MHz  band.    Call  signs  WQLW310  and  WQLX454  are  limited  to  a  radius  
           of  113  kilometers  around  a  centerpoint  near  Boulder,  Colorado.    Because  they  are  
           far  removed  from  the  Mountain  View  test  site,  there  is  no  risk  of  harmful  
           interference  to  these  operations.    The  third  license,  call  sign  WQHK852,  is  a  
           nationwide  license  covering  a  total  of  two  units.  There  are  no  specific  locations  
           associated  with  the  license.    Google  e-­mailed  the  licensee,  Mobile  Data  Solutions  
           Ltd.,  on  September  30,  2014,  to  request  any  additional  information  necessary  to  
           ensure  that  harmful  interference  is  avoided.    To  date,  Google  has  received  no  
           response.    Google  continues  to  be  prepared  to  coordinate  as  necessary  with  
           Mobile  Data  Solutions  Ltd.  to  avoid  harmful  interference  to  call  sign  WQHK852.  

         ● Federal  Operations:  The  principal  federal  incumbent  in  this  band  is  the  
           Department  of  Defense,  which  uses  the  band  for  radars  aboard  Navy  ships  and  at  
           two  land-­based  locations.  

              According  to  ITU  Recommendation  M.1465  and  a  2010  report  by  the  National  
              Telecommunications  and  Information  Administration,  these  radars  can  tolerate  a  
              maximum  interfering  signal  level  of  -­115  dBm,  assuming  a  -­10  dB  
              interference-­to-­noise  ratio,  a  0  dB  noise  figure  (which  corresponds  to  a  -­105  dBm  
              noise  level),  and  an  effective  receive  bandwidth  of  8  MHz. 2     
                
              The  Navy’s  Southern  California  Operations  Area  is  32  kilometers  away  from  the

            interference  objective.    This  analysis  accounts  for  the  fact  that  the  antennas  may  
            be  as  high  as  23  meters  above  ground  level  and  could  point  in  any  direction  in  the  
            horizontal  plane.     

            Nevertheless,  Google  is  prepared  to  coordinate  as  necessary  with  the  Department  
            of  Defense  and  the  National  Telecommunications  and  Information  Administration  to  
            ensure  that  harmful  interference  to  federal  operations  is  avoided.    

       The  proposed  experimental  operations  in  the  3.5  GHz  band  accordingly  will  be  
conducted  without  harmful  interference  to  other  authorized  users.    For  these  reasons,  Google  
requests  approval  of  this  modification.
