  • 1. Seamless VoIP sessions across Wi-Fi and GSM/3G Mattias Hansson, CEO OptiCall & Founder and Member of Board in OptiMobile [email_address] Phone: +46 702121259
  • 2. Agenda
    • VoWLAN Barriers
    • Voice over WLAN (VoWLAN) Market
    • Wireless LAN for Voice and Data
    • Seamless VoIP session across WiFi and GSM/UMTS
    • Experiences of VoWLAN trials in Kista, Sweden
    • UMA VS FMC requirement
  • 3. My background
    • Co-founder and member of board of OptiMobile (2002) – Seamless convergence WiFi and Cellular networks
    • Founder and CEO of OptiCall (2004) – leading Nordic VoWLAN distributor
      • Products portfolio: Meru Networks WLANs,
      • QTEK Dual Mode handsets (VoIP+ GSM),
      • Hitachi WLAN phones & Zultys SIP Media PBX
    • Founder and Director of Board of VoWLAN Nordics association (2005)

  • 4. VoWLAN – opportunities
    • Enterprise benefits
    • Cost Savings as mobile calls are made using VoIP/PSTN
    • No new investments: VoIP uses existing IP/WLAN networks
    GSM/UMTS WiFi
    • Terminal producers and distributors
    • New market WLAN-GSM phones
    • Service providers / virtual operators
    • New additional service offering enlarges the market
    • User benefits
    • One-phone-solution
    • VoIP has better voice quality than cellular
    • One address book
    • Mobile operators
    • More cost effective mobile network: decreased cost of sales
  • 5. VoWLAN Barriers
    • • Availability of handsets (dual mode WiFi/GSM)
    • with battery life, high QoS
    • • Willingness to jeopardize current relationships (Mobile operators will protect their investement of 3G/UMTS networks)
    • WiFi network quality lacking today. Long hand-off times and no QoS over the air between AP and device
    • • Inability to handoff between cellular and WiFi
    • network which causes dropped calls
    • • Standards for roaming and interconnect – Who
    • will be the players connecting all of the WLAN
    • networks?
  • 6. Market Growth: IP Telephony & Wireless LAN Wireless LAN Growth IP Telephony Growth IP PBX Lines – U.S. 0 10M 20M 30M 1999 2000 2001 2002 11% 2003 20% 2004 30% 2005 43% 2006 58% Source: Phillips Infotech, 2002 % IP Phones  Source: Forward Concepts, 2003 $Billions

    • Bridge
    • Wireless hub
    • Centralized security and management
    • Minimal AP
    • WLAN Switch
    • High Density
    • QoS over the air
    • Multi-Services WLAN
    • Coordinated WLAN
  • 10. Why is Meru Networks The Leader for Pervasive Deployments? Stand Alone/ Hot-Spot / Departmental Pervasive “cellular”
    • Coordinated Access Points
    • No channel design
    • No RF experts needed
    • Channel design and optimization
    • RF Experts needed
    Ease of Deployment
    • Client sees no handoff
    • High quality calls
    • Slow handoff with client re-associations
    • Dropped apps / calls
    Low Handoff
    • Upstream and Downstream QoS (without any special client inside the device (need by Spectralink)
    • High density of calls
    • No over-the-air QoS
    • Low number of calls
