  4. 4. •  January 2014, Pearson Airport’s existing DAS was 11 years old and operating on only one of the four cellular bands and with no LTE capability. •  Toronto Pearson is Canada’s largest, and a hub airport for Air Canada, the Star Alliance, WestJet and FedEx. •  The airport averages 98,900+ daily passengers (36.1M annually) •  10.8 Million connecting flights. There are over 1,175 GTAA employees •  GTAA is ranked 15th busiest flight airports in the world. •  Passenger traffic increasing 7.7% annually. 39 million PAX in 2014. •  Smart phone share in Canada increased to 74% in 2014. •  Mobile Data has increased +82% from 2013.. •  Smart Phones usage increased by 37 times more than basic cell service. Trouble brewing
  5. 5. “The ground stop has been lifted and aircraft are once again arriving. Please continue to check with your airlines for schedule changes.” — Toronto Pearson (@TorontoPearson) January 7, 2014
  6. 6. •  January 6, 2015: A Cold Snap of -40 hit halted arrivals, stranded hundreds causing extreme pressures on the existing networks. •  The airport instituted the ground stop early on Jan 7th as the wind chill readings hovered around the -40 C mark. •  More than 600 flights were cancelled during a 24 hour span due to weather. •  Thousands of passengers were stranded and sleeping at the airport, and there were thousands of bags of luggage waiting for pickup. •  GTAA: The ground stop was implemented due to the cold was affecting equipment and safety concerns related to time outdoors for employees. •  On Jan 8th, in an effort to reduce further impact, GTAA and the airlines were still advising customers to check online or by phone to confirm that their flight is operating before going to the airport. The Situation
  7. 7. ‘IRRPOPS’ = Irregular Operations: •  Between Jan 5 to 9, 2014, significant weather events disrupted airport operations and passenger flow. Rain, snow and wind chill factors as low as -39C, resulting in a Flash Freeze. Cellular Capacity in Crisis
  8. 8. GTAA IRRPOPS Event Factors •  Arriving aircraft far outnumbered departing aircraft. •  Snow clearing operations and priorities impacted passenger flow as well as severely impacting baggage flow. •  Information sharing protocols did not adequately update passengers, media or employees. •  Pearson Wi-Fi system upgrade planned, not yet implemented. •  Caused many tens of thousands of passengers unable to move through the terminal and unable to get information. Cellular Capacity in Crisis
  9. 9. GTAA Call Talking/Dispatch
  10. 10. 0.0% 2.0% 4.0% 6.0% 8.0% 10.0% Jan 1 Jan 2 Jan 3 Jan 4 Jan 5 Jan 6 Jan 7 Jan 8 Jan 9 Jan 10 Voice Dropped Calls Data Dropped Calls Source: Sample from Single Sector in T1 Dropped Voice & Data ‘Calls’ Cellular Capacity in Crisis
  11. 11. •  GTAA Board convened special panel to address issues, report issued April 7, 2014 . •  Project for solution design awarded to Genwave in May 2014. •  Scope to design and implement a solution to deliver 20+% additional cellular capacity over the IRROPS failure levels. •  Deliverable timeline: To be online and operational by December 15, 2014. Cellular Capacity Solution Scope
  12. 12. Process to Develop Solution: •  Engage Sr. Management of major Cellular Carriers and Airport to create a Taskforce team. •  Establish baseline data. •  Team developed a 5 Element Capacity Enhancement Plan. •  Key criteria: What can be done in a very short timeframe, implemented in a difficult working environment and deliver meaningful capacity improvements. Cellular Capacity Solution Scope
  13. 13. Elements 1 & 2 – Installation of AWS LTE Small Cells •  Genwave worked with Rogers & Bell to develop an RF design to deploy 55 LTE Small Cells in the public facing areas. •  This constellation of Small Cells enabled access to AWS band and LTE technology in the Pearson terminals. •  Of note: Largest deployment of small cells servicing an indoor environment in Canada at the time. Cellular Capacity Solution
  14. 14. Element 3 – Re-Sectorization of Terminals. •  During IRROPS, some sectors were overloaded and others underutilized. Team carefully examined current sectorization and re- mapped to more accurately balance capacity for today’s requirements. Element 4 – Upgrade Channel Technology. •  Canada is quite far along the smart phone and 3/4G technology adoption curve. There is reduced requirement for 2G channels. Team performed traffic analysis and migrated channels from 2G to 3G with no loss of performance for 2G customers, significantly increased capacity for 3G. Element 5 – Tweak Uplink Algorithms Cellular Capacity Solution
  15. 15. 0 50 100 150 200 250 300 IRROPS Jan 2014 Dec 2014 Uplink Channel Upgrade Re-sectorization Small Cells Baseline The Results
  16. 16. The jointly developed solution delivered 160+% additional cellular capacity, on time, on budget. Keys to success: •  Aligned and committed stakeholders. •  GTAA extended full access to premises and significant financial backing to support project •  Real time, ongoing communication to all stakeholders. Cellular Capacity Enhancement Outcome
  17. 17. •  Key vendor/partner alliances are key •  Business objectives must be shared with strategic partners •  Business growth and technological change go hand in hand •  Industry Associations need participation, and provide valuable insight and input •  Be ready for the inevitable Summary
  18. 18. •  In 2016, a Next Generation DAS will be live. This DAS will encompass all bands, all major carriers with a 10 year planned lifetime. All major carriers. •  Key in the plan is the provision for 100% additional capacity than forecast requirements. •  Process for Quality Assurance – Direct collaboration with major carriers on a quarterly basis to monitor performance and capacity. •  Interim Small Cell installation will live on as a DR facility in case it is needed in the future. Summary
  19. 19. •  Key aspect for GTAA is continuous improvement. •  Monitor and leverage potential convergence of Wi-Fi and DAS/mobile device usage. •  Explore and leverage impact of 5G •  Seek and implement monetization opportunities of wireless assets. Going Forward

  22. 22. Canada and the USA -­‐  There  are  3  huge  differences  between  Canada  and  the  USA   -­‐  In  Canada  the  Carriers  own:     •  Towers   •  Backhaul     •  DAS     -­‐  In  the  USA  Carriers  lease  all  three.    Towers,  backhaul  and  DAS  
  23. 23.  35.8  Million          325.1  Million     -­‐  Control  can  only  be  maintained  with  limited  size.   -­‐  Due  to  scale  in  the  USA  they  need  the  partnerships  to  get  to  all  the   venues.                            -­‐    Imagine  the  sheer  quanSty  of  stadiums,  hospitals,  malls,  etc.                        -­‐    It’s  simply  just  not  feasible  for  carriers  to  control  (fund)  all  aspects  of  DAS   Why?  
  24. 24. Graphics courtesy AFL Global Carrier Funded Neutral Host Enterprise Funding  Sources  (a  primer)     Again  there  are  3  scenarios  …..  
  25. 25. Carrier   •   Carrier  owns  the  DAS   •   Typically  carrier  specific.       •   Carrier  pays  for  all  iniSal  and   ongoing  hardware  and  labour   costs  (CapEx  and  OpEx)   •   Topology  of  DAS  decided  by   Carrier   •   Very  low  or  no  cost  to   Enterprise.     Advantages   •  Virtually  no  cost  to  Enterprise   •  Virtually  no  maintenance  costs.       Disadvantages   •  Coverage  only  for  Sponsor  carrier   and  guests  to  buildings  may  not  have   coverage   •  Limited  control  over  design  and   upgrades   •  Carriers  demand  good  payback  
  26. 26. Neutral  Host   •   Neutral  Host  is  a  third  party   operaSng  independent  of  Enterprise   and  Carrier.       •   Typically  this  is  a  mulScarrier  soluSon   which  is  then  leased  out  to  Carriers  for   access.     •   Topology  of  DAS  decided  by  Neutral   Host  and  approved  by  Carrier   •   AaracSve  to  carriers  in  large  venues   with  a  large  number  users.     •   AaracSve  for  the  Enterprise  due  to   greatly  reduced  or  eliminated  costs.   •   Carriers  as  tenants  provided  opSmal   signal  sources  either  off  air  or  local   BTS.   Advantages   •  Typically  mulScarrier   •  Enterprise  is  not  responsible  for   costs   •  Enterprise  is  typically  not   responsible  for  maintenance   either     Disadvantages   •  Enterprise  has  no  control  over   design  and  ongoing  evoluSon.   •  Enterprise  may  be  stuck  in  a   long  term  contract  with  liale  to   no  flexibility    
  27. 27. Enterprise   Advantages   •  Typically  mulScarrier   •  Customer  owns  system  and  controls   DAS   •  Customer  can  decide  when,  if,  and   how  to  upgrade  as  technology   evolves.   • Enterprise  owns  the  complete  DAS   system   • Enterprise  pays  for  all  iniSal  and   ongoing  hardware  and  labour  costs   (CapEx  and  OpEx)   • Enterprise  can  select  single  or   mulScarrier.    Typically  mulScarrier   allowing  new  bring-­‐your-­‐own-­‐device   (BYOD)  programs   • Topology  of  DAS  decided  by   Enterprise   • Carrier  agreement  is  sSll  required   • Capacity  is  typically  derived  from   local  cell  site  with  a  repeater  soluSon   Disadvantages   •  Enterprise  customer  must  cover  the   enSre  cost  of  the  DAS  with  no   outside  help   •  No  carrier  or  third  party  to  assist   with  troubleshooSng,  maintenance,   etc.   •  Requires  well  trained  technical  staff  
  28. 28. Carrier  Neutral  Host   •   Carrier  builds  a  DAS  but  based  on   neutral  host  design   •   They  typically  do  not  sell  access  or   service.   •   The  goal  is  to  barter  with  other   carriers  for  equal  access  to  their   systems.   • For  instance   • Carrier A – Large Shopping Mall • Carrier B – Large Stadium • Carrier C – Large Arena •   All  barter  for  shared  access  with   the  ulSmate  goal  being  equilibrium   Advantages   •  Cost  is  divided  by  the  number  of   compeSSve  local  carriers.   •  Same  approach  can  be  applied  to   towers  and  roof  access  sites.     Disadvantages   •  Carriers  may  struggle  to  keep  up  their   build  plans  to  and  balance  access  to   other  carriers  systems.   •  Designs  vary  by  compeStor.    No   ubiquitous  soluSon.  
  29. 29. Other  Cost  Drivers  of  DAS   •  DAS is expensive. •  Carriers are looking for ways to get rid of coax - Expensive to buy, expensive to install, expensive to test - This drives up the total cost and limits deployments •  New solutions over Cat5/6 solutions are much easier -  Much easier to installers -  Well trained installers are easy to find •  Solutions today tend to be one carrier specific - No support for Neutral host - Cost is still prohibitive
  30. 30. What  does  the  future  hold…   •  Most  major  stadiums,  arenas,  airports  and  shopping  malls  are  done                      -­‐  …  or  are  they  really?         Constant  announcements  that  exisSng  DAS  systems  are  being  overhauled  for  a   major  event.                            -­‐  Why  wasn’t  the  original  DAS  not  good  enough?     •  The  answer  is  usually  a  mix  of  not  enough  capacity,  didn’t  support  new   technologies,  and  missing  frequency  bands.       •  So  step  one  in  the  funding  model  is  deploy  a  technology  that  can  grow  over   Sme  and  doesn’t  require  a  major  overhaul  every  other  year.    
  31. 31. The  not  so  far  future  (3-­‐5  years)   •  The  next  fronSer  is  MDUs  (MulS-­‐Dwelling  Units)  ie  Condos                          -­‐  5G  is  desSned  to  explode  driving  true  unlimited  data  plans     •  First  we  cut  the  phone  line.    Next  we’ll  cut  the  internet  cord!                          -­‐  Based  on  today’s  technology  this  may  not  be  economically  viable.         •  One  of  two  things  have  to  happen  (or  even  beaer  both!)  :                              -­‐  The  technology  becomes  more  affordable  or                            -­‐  The  infrastructure  required  is  funded  by  alternaSve  methods     •  Water,  HVAC,  Electricity,  Cable  and  Phone  are  all  standard                            -­‐  Wireless  networks  should  be  a  standard  part  of  the  building       •  Voice,  Internet,  etc.  could  all  come  from  your  wireless  provider
