 PUBLIC  NOTICE  Federal  Communications  Commission  445  12th  St.,  S.  W.  Washington,  D.  C.  20554  News  Media  Information  202  /  418-  0500  Fax-  On-  Demand  202  /  418-  2830  TTY  202  /  418-  2555  Internet:  http://  www.  fcc.  gov  ftp.  fcc.  gov 
 DA  00-  2833  Released:  December  15,  2000 
 OFFICE  OF  ENGINEERING  AND  TECHNOLOGY  DECLARES  ASCOM  WIRELESS 
 SOLUTIONS  INC.  REQUEST  FOR  WAIVER  OF  PART  15  FOR  OPERATION  IN  THE 
 1910-  1920  MHZ  BAND  TO  BE  A  "PERMIT-  BUT-  DISCLOSE"  PROCEEDING  FOR  EX  PARTE  PURPOSES 


 On  September  13,  2000,  Ascom  Wireless  Solutions  Inc.  ("  Ascom"),  Petition  for 
 Waiver  of  Sections  15.319  and  15.321  of  the  Commission's  rules  to  permit  operation  of 
 Ascom's  unlicensed  personal  communications  service  ("  PCS")  isochronous  devices  in  the 
 1910-  1920  MHz  band  for  the  purpose  of  providing  wireless  telephone  service  within 
 Cook  County,  Illinois,  New  York  County,  New  York,  San  Francisco  County,  California, 
 and  Philadelphia  County,  Pennsylvania. 


 Unlicensed  PCS  ("  UPCS")  operation  is  permitted  in  the  1910-  1920  MHz  band 
 under  Part  15  of  the  Commission's  regulations.  Operation  in  the  1910-  1920  MHz  band  is 
 limited  to  use  by  asynchronous  devices.  Asynchronous  devices  transmit  at  irregular 
 intervals,  as  is  typical  of  packet  data  applications.  The  Wireless  Information  Networks 
 Forum  has  filed  a  petition  for  rule  making,  RM-  9498,  requesting  that  isochronous  UPCS 
 devices  be  permitted  to  use  the  1910-  1920  MHz  band  in  combination  with  the  adjacent 
 1920-  1930  MHz  band.  Isochronous  UPCS  devices  typically  have  a  fixed  frame  structure 
 and  transmit  regular,  periodic  signals,  such  as  time-  division  voice  systems. 


 The  Commission's  Office  of  Engineering  and  Technology  ("  OET")  is  reviewing 
 Ascom's  request  to  determine  whether  a  waiver  of  the  rules  should  be  granted.  OET  seeks 
 comments  from  interested  parties  concerning  this  waiver  request.  OET  has  concluded  that 
 in  order  to  permit  a  fuller  exchange  on  the  issues  under  consideration  in  this  proceeding,  it 
 should  be  treated,  for  ex  parte  purposes,  as  a  "permit-  but-  disclose"  proceeding,  in 
 accordance  with  Section  1.1200(  a)  of  the  Commission's  rules,  and  is  subject  to  the 
 requirements  under  Section  1.1206(  b)  of  the  Commission's  rules. 


 Interested  parties  filing  comments  or  oppositions  to  this  petition  are  invited  to  do 
 so  no  later  than  January  16,  2001.  Parties  filing  replies  may  do  so  by  January  31,  2001. 
 All  filings  should  be  submitted  to  the  Office  of  the  Secretary  and  must  include  the  above 
 referenced  DA  number.  For  further  information  on  this  waiver  request,  contact  Rodney 
 Conway,  Office  of  Engineering  and  Technology,  via  phone  at  (202)  418-  2904,  e-  mail  at 
 rconway@  fcc.  gov  or  TTY  (202)  418-  2989.
