7. Emerging Technologies
 Cellular Connectivity over Wi-Fi /DAS Replacement
 Geo Contextual Information Exchange
 Contextual Security controls
11/5/2015 | 7

8. Cellular Connectivity over Wi-Fi
 Virtually all carriers
 Some pilots already exist
 Production for most reported by next year
 Allows elimination of DAS
» Except Large Public Venue (LPV)
» Requires Engineered Systems
 Minimum connection strength (-55 dB example)
 Drop connection strength (-67 dB example)
11/5/2015 | 8

9. GEO Contextual Information Exchange
 Application on smart device
 System knows device location
 Users
» Access to resources
 Directions, services, discounts, information
 Facility Operators
» Information
 Density, Attendance, Demands…
» Influence behaviors
 Which resources are used
 Selling opportunities
11/5/2015 | 9

10. Contextual Security Controls
 Network Access determined by
» User authentication
» Device used
» Applications used
» Location of user
11/5/2015 | 10

11. Aruba ClearPass
 Network Authentication
 Provides access based on use cases
» BYOD
» Authenticated Devices, Users
 Integrates with Microsoft Active Directory or virtually any
authentication provider
 Vendor Agnostic
 It Works!
11/5/2015 | 11

12. Mobilizing Employees
 Opportunities
» BYOD
» Secured Networks
» Guest
» Multiple Devices
 Challenges
» Current Network Structure
 Configuration, capacity, controls
» Skilled Resources
 Authentication, Network Structure
» Budget

13. Real World Performance - Major
Components
 Bandwidth to the Internet
 Infrastructure Capacity
» Access Layer
» Aggregation
» Core
» Firewalls
 Wi-Fi system
 Client Device
11/5/2015 | 13

14. Real World Performance - Typical
Bottlenecks
 Internet Bandwidth
 Firewall Capacity
 Aggregation layer
 Access layer
 Wireless layer
11/5/2015 | 14

15. Real World Performance - Enterprise
 Assuming
» 802.11ac (1:1 Clients)
» Engineered system
» Assumes healthy infrastructure, current client
 140 Mbps Down
 40 Mbps Up
 Sub 20 millisecond latency
11/5/2015 | 15

16. Real World Performance – Large Public
Venue (LPV)
 Assuming
» 10,000 Simultaneous Users
» 802.11ac Device
» Engineered system
» Assumes healthy infrastructure, current client
 1-1.5 Mbps Down
 1-1.5 Mbps Up
 Sub 20 millisecond latency
11/5/2015 | 16

17. Enterprise System Requirements –
Partner Specifications
 Structured Cabling Certification (if used)
 Fixed Network Certifications
 Wireless Network Certifications
 Experience in your key challenges
» Large Public Venue
» BYOD, Mobility, Guest Management
» Video, M2M
» Licensed Point to Point
» Point to Multipoint
» Towers
11/5/2015 | 17

18. Enterprise System Requirements –
Selection Approach
 Set performance requirements
» Number of devices total
 Currently 3.8 per user in some parts of the country
 Designing around 7 per user in latest RFP’s
» Simultaneous devices
 How many devices will be expected to be communicating at the same time
» Bandwidth expectations
 5 Mbps? 20 Mbps? 100 Mbps?
» Coverage areas
 Produce CAD drawings. Be specific.
» Signal Strength
 -49 dB average signal strength
 -65 dB minimum signal strength
11/5/2015 | 18

19. Design Considerations -
Recommendations
 Consider the whole network
» Wi-Fi capacity will oversubscribe your network
 Pre and Post Site Survey’s
» Ekahau Site Survey is our current favorite
 External Interference
 Use 6A structured cabling with single cable run
 Provide redundancy at the closet or switch level
 Multicast can be a challenge
 Limit spanning tree where possible
 Consider Environment
» Marble on walls can impact over 30 dB
11/5/2015 | 19

20. Design Considerations - Continued
 Servers stay on structured cabling
» All others can be wireless
 Printers-Debatable
» Exclude heavy use or chatty printers
» May include small local printers
 Density Review
» Key differential– How many simultaneous devices can they support?
 Aruba current high performance at 255 devices per radio (510 per AP)
 Others range down to 25-50 per radio
 Limit Signal
» Fire any vendor that only solves problems through “More APs are needed”
11/5/2015 | 20

21. Acquiring New Systems
 Pick your engineering firm first
» Select someone who has a wide range of wireless AND wired network
experience in the areas you need
 Perform Pre and Post Site Survey’s using CAD drawings
 Set performance requirements
» If you are not confident about vendor, perform a bake off
» If you are confident, require performance remediation at no cost
