Identification  of  the  Information  for  Which  Confidential  Treatment  is  Sought:     Google’s  request  for  confidential  treatment  is  limited  to  the  following  information  that  has   been  redacted  from  the  STA  Application  and  complementary  exhibits.    Google  does  not   seek  to  withhold  from  public  inspection  information  in  the  STA  Application  necessary  for   interference  mitigation,  including  applicant  name,  contact  information,  test  location,   frequency,  output  power,  effective  radiated  power,  emission  characteristics  and   modulation.       Exhibit  A  -­  Special  Temporary  Authority  Justification:       Google  requests  confidential  treatment  of  the  following  underlined  text  from  Exhibit  A  that   contains  confidential  and  proprietary  information  regarding  the  proposed   tests/experiments:     Consistent  with  the  standards  set  forth  in  Section  5.61  of  the  Federal   Communications  Commission’s  (FCC’s  or  Commission’s)  Rules,  47  C.F.R.  §  5.61,   Google  Inc.  (Google)  requests  Special  Temporary  Authority  (STA)  to  conduct   demonstrations  of  experimental  transmitters.    The  STA  is  sought  for  a  period  of  180   days  beginning  on  November  13,  2014.    Google  outlines  below  its  need  for  the   requested  STA  and  the  reasons  that  the  STA  should  be  granted  expeditiously.     Request  for  Confidential  Treatment  -­  Page  1  

    PUBLIC  REDACTED  VERSION   Google  Inc.   File  No.  0923-­EX-­ST-­2014       Google  requests  the  STA  to  [REDACTED].       The  tests  will  use  point-­to-­point  communications  between  between  three  sites   located  in  the  Bay  Area.    The  locations  are  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  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.1   Google  will  transmit  5.8  GHz  and  24.2  GHz  signals  from  Location  1  to  Locations  2   and  3.    Google  will  transmit  millimeter  wave  band  signals  between  Locations  1  and  2   and  between  Locations  1  and  3.    [REDACTED].         Figure  1:  5.8  GHz  and  24.2  GHz  transmissions2         1    As  explained  below,  Google  believes  the  proposed  operations  in  the  millimeter  wave  bands  comply  with   the  FCC’s  technical  rules  for  those  bands  and  do  not  require  additional  authorization.    Should  the   Commission  determine  that  an  STA  is  required  for  the  proposed  testing  in  the  millimeter  wave  bands,  one  is   requested.     2    Drawing  is  for  illustrative  purposes  and  is  not  to  scale.     Request  for  Confidential  Treatment  -­  Page  2

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  by  requiring  all  third  parties  involved  in  the  testing  process   to  execute  robust  nondisclosure  agreements.             8    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
