Agenda

• The New Enterprise
• Adding Mobility to Fixed Wireless Broadband
• End-user expectations
• Carrier expectations
• Key challenges
• Wi-Fi and WiMAX scenarios
• Colubris and Redline collaboration
• Summary

The New Enterprise

• Strong momentum to complete conversion to all-IP
  networks
• Wi-Fi is more and more seen as an INTEGRAL part
  of the Corporate LAN Backbone
• Security and QoS are now mature enough
• Management solutions are adequate
• Ready for UNIFICATION of the wired and wireless
  worlds
• Looking to Wi-Fi to add MOBILITY dimension
• Looking to Wi-Fi to hide specifics of Broadband
  Access Network

4
The New Enterprise

• Adding MOBILITY with Wi-Fi facilitates seamless
  access to the information
• Voice is information as much as data
• Helps increase productivity reduce staff stress
• Access to data is still possible, even away from
  desk
• Looking for a single wireless infrastructure for
  both voice and data
• Micro-BTS and GSM-repeaters dont offer adequate
  data performances
• Multitude purpose-built wireless devices become
  available

5
Unifying the wired and wireless worlds

• Unification of the wired and wireless worlds
  means
• Single set of user credentials
• Single set of security policies
• Single user profile QoS, VLAN, Bandwidth limits
• Overall, much better User Experience
• But what about the IT Staff
• Re-use of 100 of the wired infrastructure
  capabilities for Security, QoS and Management
• No need to manage parallel solutions
• Extensible and Scalable architecture, future-proof

WiFi and WIMAX Convergence

• Due to the proliferation of WIFI in end user
  devices it is the smart choice to add a mobility
  dimension to the fixed wireless broadband service
  offered by WiMAX
• Seamless mobility across Layers 2 and 3
• End-to-end QOS
• Strong integration with existing OSS/BSS and
  various Core IP networks is easily achievable
• WIMAX is ideal for backhaul or business access
  where other broadband technologies are not
  available or cost effective

12
There is an immediate need for mobility!

• Mobility is key to the unification of service
  delivery across various disparate backhaul
  technologies
• Services such as Voice are expected to be
  available from any locations, at all times
• Other data services can also benefit from
  mobility, such as transportation, shipping
  yards, etc.
• Enables continuous service availability from a
  single device
• Same device shall be usable across various
  Broadband Access networks

13
End-user expectations

• Seamless service availability from a single
  device, independent of the Broadband Access
  Network
• For voice, this means a single device, phone
  number and voice mailbox
• Use Cellular as extension when no Fixed Broadband
  coverage
• Ease of use
• Use currently available devices, this means
  Wi-Fi!
• Battery life shall be comparable to a cellular
  device
• Familiar user experience
• Service shall provide a consistent look and feel
  with a single set of credentials and no need to
  login again as long as user remains within
  coverage

14
Carrier / Operator Expectations

• Service offering flexibility
• Solution deployed needs to fit into existing
  service framework and facilitate new services
  with a Mobility Dimension
• Business model flexibility
• Underlying service delivery infrastructure shall
  fit into current business models and facilitate
  the introduction of new models with strong focus
  on Mobile and Managed Services
• ROI considerations
• Cost of deployment/update of core infrastructure
• Cost of deployment of wireless coverage
• Ability to leverage existing OSS and BSS
  infrastructure

15
Key Challenges

• RF Planning and Provisioning
• Avoid dreaded truck rolls whenever possible
• Solution and network management
• All interlocking pieces need to be unified under
  a single management umbrella
• QOS
• End to end, predictable Quality of Service
• Security
• Using Wireless shall not reduce risks and
  exposure
• Seamless service offering across various IP
  subnets and even distinct access networks
• What about DSL, DOCSIS, Metro Ethernet?

16
Adding Mobility to WiMAX NOW!

• Wi-Fi is the perfect end-user wireless technology
  to add seamless mobility to Fixed Broadband
  Wireless
• Across a WiMAX backhaul
• Between WiMAX end-points (Subscriber Stations)
  and even across WiMAX Base Stations
• Colubris InMotion MSC and InReach MAP provide
• Seamless mobility
• Session and service continuity
• Focuses on the Control Plane to free up the Fast
  Data Path

Focus of collaboration

• Immediate availability
• Solution is based on current product offerings
• Licensed and unlicensed band support
• Flexible solution based on country specific radio
  regulations
• Turn Fixed Broadband Wireless into
• Multi-Service end-to-end QOS and Security
• Mobile seamless handover for Wi-Fi, WiMAX and
  even Cellular
• Managed service offering comprehensive RF
  planning, provisioning and manageability

19
Proposed Phased Approach

• Phase 1
• launch of joint solution for Mobility across
  Fixed Broadband Wireless backhaul
• Phase 2
• Improve Management Integration to facilitate
  deployment, provisioning and manageability
• Beyond Phase 2
• Further integration to enhance interface to OSS
  and BSS with focus on ease of creation and
  deployment of new services
