                             Google  requests  that  the  Experimental  License  be  granted  for  a  period  of  24  
                    months.    The  Experimental  License  is  needed  for  continued  demonstration  and  
                    testing  of  experimental  transmitters.     
  
                             Consistent  with  0923-­EX-­ST-­2014  and  0460-­EX-­ST-­2015  (Call  Sign  
                    WH9XZW),  testing  will  continue  to  measure  [REDACTED].    [REDACTED].  
                    [REDACTED].    [REDACTED].    Because  such  data  is  not  readily  available,  Google  
                    will  continue  to  measure  [REDACTED].     
                               
                             The  tests  will  continue  to  use  point-­to-­point  communications  between  
                    between  three  sites  located  in  the  Bay  Area.    The  locations  continue  to  be  as  follows:    

                                ●     Location  1:  37°20’40’’  N,  122°12’56’’  W

                               The  equipment  used  will  continue  to  include  three  types  of  radios:  one  that  
                    operates  in  the  frequencies  between  5775  MHz-­5825  MHz  (5.8  GHz);;  one  that  
                    operates  at  24.2  GHz;;  and  one  that  operates  in  the  71-­76  GHz  and  81-­86  GHz  
                    millimeter  wave  bands.    Google  will  continue  to  transmit  5.8  GHz  and  24.2  GHz  
                    signals  from  Location  1  to  Locations  2  and  3.    Google  will  continue  to  transmit  
                    millimeter  wave  band  signals  between  Locations  1  and  2  and  between  Locations  1  
                    and  3.    No  transmissions  will  occur  between  Locations  2  and  3.    [REDACTED].

                         (1)  The  transmitter  will  continue  to  be  [REDACTED].    The  other  principal  
               operations  in  this  band  are  Part  15  unlicensed  devices,  Part  18  ISM  devices,  and  
               amateur  radio  operators.5     [REDACTED].    [REDACTED],  the  closest  possible  
               operations  would  be  at  least  300  meters  away,  [REDACTED].    Once  Google’s  signal  
               travels  300  meters,  the  signal  in  the  line-­of-­sight  (LOS)  path  will  have  attenuated  by  
               -­66  dB.    The  signal  power  received  by  an  omnidirectional  antenna  placed  at  300  
               meters  from  the  transmitter,  if  the  receiver  is  centered  with  the  correct  polarization  in  
               the  beam  of  the  LOS  link  and  there  are  no  intervening  obstructions,  would  be  at  most  
               -­46  dBm.    This  signal  power  is  well  below  the  signal  strengths  from  typical  Wi-­Fi  
               transmitters  in  the  5  GHz  band  and  is  not  expected  to  cause  harmful  interference.  
               By  comparison,  interference  from  commercial  Wi-­Fi  equipment  can  be  as  much  as  
               -­10  dBm  in  an  urban  environment.    For  receivers  not  in  the  LOS  path,  or  located  on  
               the  ground  and  obscured  by  buildings  or  foliage,  the  strength  of  Google’s  signal  will  
               be  significantly  less  than  the  strength  predicted  by  the  ideal  free  space  calculation  
               set  forth  above.  
                           
                         (2)  Google  will  continue  to  employ  highly  directional,  narrow  bandwidth  
               transmissions.    The  full  beamwidth  of  the  antenna  is  only  6.2  degrees.    Other  users  
               of  the  5.8  GHz  band  are  unlikely  to  be  transmitting  directly  in  the  beamwidth,  and  as  
               a  result,  their  communications  are  unlikely  to  be  affected.     
                           
                         24.2  GHz  operation:    ​Google’s  continued  testing  in  the  24  GHz  band  
               similarly  will  avoid  harmful  interference  to  other  users  of  the  band.    There  are  three  
               classes  of  non-­federal  users  in  the  24.05-­24.25  GHz  band:  Part  18  ISM  users,  Part  
               90  private  land  mobile  radio  users,  and  Part  97  amateur  radio  users.     
                           
                         Google’s  operations  will  continue  to  avoid  interference  with  Part  18  users,

               will  continue  to  employ  extremely  directional,  narrow  bandwidth  transmissions.  
               Indeed,  the  full  beamwidth  of  the  antenna  at  24.2  GHz  is  only  1.4  degrees,  making  it  
               extremely  unlikely  that  unaffiliated  transmissions  will  pass  through  the  main  beam  of  
               the  antenna.    And  as  with  the  5.8  GHz  transmissions,  all  of  the  24.2  GHz  transmitters

                                                                                          File  No.  ​0307-­EX-­PL-­2015  
  
2.       Identification  of  the  Commission  proceeding  in  which  the  information  was  
         submitted  or  a  description  of  the  circumstances  giving  rise  to  the  submission.  
  
          The  above-­referenced  Exhibits  were  submitted  to  the  Commission  in  support  of  the  
Experimental  License.    These  Exhibits  were  filed  with  the  Office  of  Engineering  and  Technology  
on  May  13,  2015.    For  additional  information,  please  see  File  No.  0307-­EX-­PL-­2015.    
  
  
3.        Explanation  of  the  degree  to  which  the  information  is  commercial  or  financial  or  
          contains  a  trade  secret  or  is  privileged.     
  
          The  information  requested  to  be  kept  confidential  has  significant  commercial  value.    The  
details  of  the  Experimental  License  tests/experiments  may  include  trade  secret  information.  
                                                                                                                 8
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.    
  
          In  addition,  agreements  entered  into  between  Google  and  the  parties  that  provided  
equipment  for  testing  or  will  provide  analysis  of  test  results  require  that  confidential  information  
of  the  parties  be  held  in  strict  confidence,  and  that  such  information  not  be  disclosed  to  any  third  
party  (with  limited  exceptions  not  applicable  to  this  request).    The  manufacturer  name  and  
model  number  constitutes  confidential  trade  secrets,  technical  information,  and  business  
information  under  the  agreements.  
            
            
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  Experimental  License  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.

     ​Examination  of  Current  Policy  Concerning  the  Treatment  of  Confidential  Information  Submitted  to  the  
Commission​,  Report  and  Order,  GC  Docket  No.  96-­55,  at  para.  3,  (released  Aug.  4,  1998)  (defining  “trade  
secrets”  for  purpose  of  Commission  rules  on  confidential  treatment).  
                                                                        Request  for  Confidential  Treatment  -­  Page  10

                                                                                                        Google  Inc.  
                                                                                     File  No.  ​0307-­EX-­PL-­2015  
  
     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  by  requiring  all  third  parties  involved  in  the  testing  process  to  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  
has  only  been  disclosed  to  third  parties  pursuant  to  restrictive  safeguards.  
            
          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.”)  
  
  
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  
Experimental  License  after  the  Commission  has  ruled  on  the  Request  for  Confidentiality  is  not  
necessary  for  the  Commission  to  fulfill  its  regulatory  responsibilities.

         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)  requests  
an  Experimental  Radio  Service  License  (Experimental  License)  and  outlines  below  the  
compelling  reasons  why  ​0307-­EX-­PL-­2015​  should  be  granted  expeditiously.  
           
         Google  requests  that  the  Experimental  License  be  granted  for  a  period  of  24  months.  
The  Experimental  License  is  needed  for  continued  demonstration  and  testing  of  experimental  
transmitters.     
  
         Consistent  with  0923-­EX-­ST-­2014  and  0460-­EX-­ST-­2015  (Call  Sign  WH9XZW),  testing  
will  continue  to  measure  [REDACTED].    [REDACTED].    [REDACTED].    [REDACTED].    Because  
such  data  is  not  readily  available,  Google  will  continue  to  measure  [REDACTED].     
  
         The  tests  will  continue  to  use  point-­to-­point  communications  between  between  three  
sites  located  in  the  Bay  Area.    The  locations  continue  to  be  as  follows:    

              ●     Location  1:  37°20’40’’  N,  122°12’56’’  W  
              ●     Location  2:  37°25’3’’  N,  122°4’39’’  W  
              ●     Location  3:  37°25’33’’  N,  122°04’20’’  W  
  
         The  equipment  used  will  continue  to  include  three  types  of  radios:  one  that  operates  in  
the  frequencies  between  5775  MHz-­5825  MHz  (5.8  GHz);;  one  that  operates  at  24.2  GHz;;  and  
one  that  operates  in  the  71-­76  GHz  and  81-­86  GHz  millimeter  wave  bands.    Google  will  
continue  to  transmit  5.8  GHz  and  24.2  GHz  signals  from  Location  1  to  Locations  2  and  3.

15.407(a)(3).    The  following  attributes  of  the  testing  will  further  mitigate  any  potential  
interference  concerns:    
  
         (1)  The  transmitter  will  continue  to  be  [REDACTED].    The  other  principal  operations  in  
this  band  are  Part  15  unlicensed  devices,  Part  18  ISM  devices,  and  amateur  radio  operators.5  
[REDACTED].    [REDACTED],  the  closest  possible  operations  would  be  at  least  300  meters  
away,  [REDACTED].    Once  Google’s  signal  travels  300  meters,  the  signal  in  the  line-­of-­sight  
(LOS)  path  will  have  attenuated  by  -­66  dB.    The  signal  power  received  by  an  omnidirectional  
antenna  placed  at  300  meters  from  the  transmitter,  if  the  receiver  is  centered  with  the  correct  
polarization  in  the  beam  of  the  LOS  link  and  there  are  no  intervening  obstructions,  would  be  at  
most  -­46  dBm.    This  signal  power  is  well  below  the  signal  strengths  from  typical  Wi-­Fi  
transmitters  in  the  5  GHz  band  and  is  not  expected  to  cause  harmful  interference.    By  
comparison,  interference  from  commercial  Wi-­Fi  equipment  can  be  as  much  as  -­10  dBm  in  an  
urban  environment.    For  receivers  not  in  the  LOS  path,  or  located  on  the  ground  and  obscured  
by  buildings  or  foliage,  the  strength  of  Google’s  signal  will  be  significantly  less  than  the  strength  
predicted  by  the  ideal  free  space  calculation  set  forth  above.  
  
         (2)  Google  will  continue  to  employ  highly  directional,  narrow  bandwidth  transmissions.  
The  full  beamwidth  of  the  antenna  is  only  6.2  degrees.    Other  users  of  the  5.8  GHz  band  are  
unlikely  to  be  transmitting  directly  in  the  beamwidth,  and  as  a  result,  their  communications  are  
unlikely  to  be  affected.     
  
         24.2  GHz  operation:    ​Google’s  continued  testing  in  the  24  GHz  band  similarly  will  avoid  
harmful  interference  to  other  users  of  the  band.    There  are  three  classes  of  non-­federal  users  in  
the  24.05-­24.25  GHz  band:  Part  18  ISM  users,  Part  90  private  land  mobile  radio  users,  and  Part  
97  amateur  radio  users.     
           
         Google’s  operations  will  continue  to  avoid  interference  with  Part  18  users,  who  do  not  
need  a  license  to  operate  their  equipment.    Although  Google’s  test  equipment  will  continue  to  
exceed  the  field  strength  limitations  set  forth  in  47  C.F.R.  §15.249  for  fixed,  point-­to-­point  
operations  in  the  24.2  GHz  band,  the  transmissions  will  continue  to  employ  extremely  
directional,  narrow  bandwidth  transmissions.    Indeed,  the  full  beamwidth  of  the  antenna  at  24.2  
GHz  is  only  1.4  degrees,  making  it  extremely  unlikely  that  unaffiliated  transmissions  will  pass  
through  the  main  beam  of  the  antenna.    And  as  with  the  5.8  GHz  transmissions,  all  of  the  24.2  
GHz  transmitters  will  continue  to  be  placed  [REDACTED].  
           
         Based  on  a  query  of  the  FCC’s  universal  licensing  system  (ULS),  there  are  six  active,  
licensed  Part  90  users  in  San  Mateo  or  Santa  Clara  County  in  the  spectrum  between  24.05  GHz  
and  24.25  GHz.6    No  disruptions  to  ​Call  Signs  KA69657,  KD3081,  KD36972,  KE2004,  KP4696,  
and  KL5302​  have  been  noted  or  reported  during  tests  taking  place  under  Google’s  grant  of

directional  links  pass  to  the  south  of  the  areas  of  operation  for  Call  Signs  KA69657  (Half  Moon  
Bay),  KD3081  (Palo  Alto),  KD36972  (South  San  Francisco),  KE2004  (San  Bruno),  and  KP4696  
(San  Mateo).    Google’s  transmissions  pass  to  the  north  of  the  area  of  operation  for  call  sign  
KL5302  (Sunnyvale).    In  addition,  in  most  of  these  cases,  Google’s  transmissions  will  continue  
to  be  directed  ​away​  from  the  operation  of  the  Part  90  licensees.    
             
             There  are  no  active,  licensed  Part  97  users  in  either  San  Mateo  or  Santa  Clara  County  
in  the  spectrum  between  24.05  GHz  and  24.25  GHz.    Operations  in  other  counties  are  unlikely  
to  experience  interference  as  the  transmitter  will  continue  to  be  located  in  the  southern  part  of  
San  Mateo  County,  close  to  the  Santa  Clara  County  border.     
  
           Google  is  prepared  to  coordinate  with  the  National  Telecommunications  and  Information  
Administration  to  ensure  that  testing  does  not  interfere  with  any  earth  exploration  satellites  
services  in  this  band.7     
  
           Millimeter  wave  band  operation:​  Google’s  testing  will  continue  to  comply  with  the  
technical  specifications  set  forth  in  Part  101  for  commercial  millimeter  wave  operations  in  the  
71-­76  GHz  and  81-­86  GHz  band  and  Google  believes  no  experimental  authorization  is  
necessary.    Nevertheless,  because  the  rules  do  not  explicitly  address  continuous  waveform  
transmissions  in  these  bands,  and  because  these  operations  are  covered  by  Google’s  current  
Special  Temporary  Authority,  Google  requests  an  Experimental  License  to  continue  to  conduct  
its  test  operations  in  the  band  to  the  extent  that  the  Commission  determines  such  experimental  
authority  is  necessary.    Google  has  registered  its  links  with  an  authorized  third-­party  database  
manager  for  these  bands.  
             
           Finally,  as  noted,  Google  has  already  been  conducting  similar  tests  in  this  area  under  a  
grant  of  Special  Temporary  Authority,  and  no  disruptions  have  been  noted.
