    • Implementing VoIP in a wireless world Herman Abel Product Manager Aculab (booth 402) [email_address] Phone: +44 1908 273815
    • Agenda
      • What is wireless VoIP?
      • Three key issues
      • Wireless VoIP makes money
      • Your opportunities with wireless VoIP
      • Summary
    • Is this wireless VoIP?
      • Used for voice communications between kids
      • Uses wireless, digital and packetised voice
      • Connected to Internet
      • Community of ‘live objects’ around the globe
      No, it is not wireless VoIP!
    • Defining the wireless VoIP
      • A blend of basic ingredients is required:
        • Wireless LAN / WAN
        • IP framing on the user / edge device
        • Support of mobility / roaming
        • Multiple access points (cells / pico-cells / base stations)
        • Integration of voice and data applications (video is next)
      Mobility is the key issue No.1! Infrastructure is the key issue No.2! Mobile Internet is the key issue No.3!
      • Two types of wireless VoIP
        • Enterprise wVoIP indoor via Wi-Fi
        • Public Internet wVoIP via Wi-Fi / WiMAX
      • Dual mode access technologies / phones
      Mobility – wireless VoIP gets you unplugged! GSM / CDMA outdoor VoWiFi indoor Public cells outdoor Private pico-cell indoor FMC UMA Fixed / mobile convergence Unlicensed mobile access
    • Infrastructure
      • Simplicity
        • Wireless VoIP offers much simpler indoor infrastructure
      • Cost
        • Cheaper to install and maintain
      • Quality
        • Wireless should be on a par with wireline
        • Coverage, congestion, etc.
    • Integration of voice with data applications
      • It’s not that simple phone anymore…
      • Voice is integrated with office tools
        • Mobile email access, organiser, etc.
      • Unified messaging
        • Push-to-talk
        • Instant messaging
      • Internet access
        • Browsing
        • Enterprise wVoIP + Internet VoIP ( )
    • Technologies overview
      • Wi-Fi
        • ‘ Last foot’, enterprise level wLAN technology
        • Robust, deployed, proven, cheap and simple
        • Unlicensed
        • 150 feet indoors, 300 feet outdoors
      • WiMAX
        • ‘ Last mile’, cell-like technology
        • Promising, but yet to be proven
        • Licensed spectrum – costs £ € $ ¥
        • 30 miles outdoors
    • Technologies overview WCDMA HSDPA HSUPA Super3G TD-CDMA Flash-OFDM Wi-Fi WiMAX Availability VoIP capability Maximum latency Speed per user 2007 2010 2008 300ms No No 200ms 100ms 25ms 100ms 50ms 200ms 100ms 200kbps 1Mbps 2Mbps <10Mbps 1Mbps 1.5Mbps >10Mbps <10Mbps
    • Wireless VoIP makes money In building (DoCoMO, Passage) In building + public areas (BT Fusion) VoWiMAX (Korea telecom, Sprint) In building fixed (Skype/ Siemens DECT) Public areas (Vonage/ Boingo) IMS-based services (Super3G) DIY cellular (Skype on Motorola phone) (Source: Analysis)
    • Your opportunities with wireless VoIP
      • Wireless VoIP roaming
        • Fast call routing and seamless cell switching
        • Cell congestion management
        • Coverage improvements
      • Integration of complete solutions
        • Integration with IP-PBX, gateways, media servers
        • Support for voicemail, call transfer, conferencing, email, fax, video, etc.
    • Your opportunities with wireless VoIP
      • Scalability, availability, resilience
        • Growing an enterprise solution
        • Related to roaming
      • Quality of service (QoS)
        • Audio quality affected by delay, jitter and packet loss
        • Codecs, PLC, bandwidth management
    • Your opportunities with wireless VoIP
      • Security
        • Wireless channel security
        • Wireline security (Secure RTP, TLS, SIPS, etc.)
      • Dual mode end user devices or services
        • FMC or UMA
        • Feature rich, low cost or oriented to a particular market segment
    • Summary
      • Three key issues of wireless VoIP:
        • Mobility
        • Simpler ‘last foot’ infrastructure
        • Benefits of integration of wireless voice with data
      • Radio access technologies include Wi-Fi, WiMAX, HSDPA/HSUPA, TD-CDMA and Flash-OFDM
      • Wireless VoIP can be managed, private, public, portable or truly mobile
      • Business opportunities exist in roaming, security, scalability, QoS and dual mode operation
