Introduction to Wireless

  1. 1. Implementing VoIP in a wireless world Herman Abel Product Manager Aculab (booth 402) [email_address] Phone: +44 1908 273815
  2. 2. Agenda <ul><li>What is wireless VoIP? </li></ul><ul><li>Three key issues </li></ul><ul><li>Wireless VoIP makes money </li></ul><ul><li>Your opportunities with wireless VoIP </li></ul><ul><li>Summary </li></ul>
  3. 3. Is this wireless VoIP? <ul><li>Used for voice communications between kids </li></ul><ul><li>Uses wireless, digital and packetised voice </li></ul><ul><li>Connected to Internet </li></ul><ul><li>Community of ‘live objects’ around the globe </li></ul>No, it is not wireless VoIP!
  4. 4. Defining the wireless VoIP <ul><li>A blend of basic ingredients is required: </li></ul><ul><ul><li>Wireless LAN / WAN </li></ul></ul><ul><ul><li>IP framing on the user / edge device </li></ul></ul><ul><ul><li>Support of mobility / roaming </li></ul></ul><ul><ul><li>Multiple access points (cells / pico-cells / base stations) </li></ul></ul><ul><ul><li>Integration of voice and data applications (video is next) </li></ul></ul>Mobility is the key issue No.1! Infrastructure is the key issue No.2! Mobile Internet is the key issue No.3!
  5. 5. <ul><li>Two types of wireless VoIP </li></ul><ul><ul><li>Enterprise wVoIP indoor via Wi-Fi </li></ul></ul><ul><ul><li>Public Internet wVoIP via Wi-Fi / WiMAX </li></ul></ul><ul><li>Dual mode access technologies / phones </li></ul>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
  6. 6. Infrastructure <ul><li>Simplicity </li></ul><ul><ul><li>Wireless VoIP offers much simpler indoor infrastructure </li></ul></ul><ul><li>Cost </li></ul><ul><ul><li>Cheaper to install and maintain </li></ul></ul><ul><li>Quality </li></ul><ul><ul><li>Wireless should be on a par with wireline </li></ul></ul><ul><ul><li>Coverage, congestion, etc. </li></ul></ul>
  7. 7. Integration of voice with data applications <ul><li>It’s not that simple phone anymore… </li></ul><ul><li>Voice is integrated with office tools </li></ul><ul><ul><li>Mobile email access, organiser, etc. </li></ul></ul><ul><li>Unified messaging </li></ul><ul><ul><li>Push-to-talk </li></ul></ul><ul><ul><li>Instant messaging </li></ul></ul><ul><li>Internet access </li></ul><ul><ul><li>Browsing </li></ul></ul><ul><ul><li>Enterprise wVoIP + Internet VoIP ( ) </li></ul></ul>
  8. 8. Technologies overview <ul><li>Wi-Fi </li></ul><ul><ul><li>‘ Last foot’, enterprise level wLAN technology </li></ul></ul><ul><ul><li>Robust, deployed, proven, cheap and simple </li></ul></ul><ul><ul><li>Unlicensed </li></ul></ul><ul><ul><li>150 feet indoors, 300 feet outdoors </li></ul></ul><ul><li>WiMAX </li></ul><ul><ul><li>‘ Last mile’, cell-like technology </li></ul></ul><ul><ul><li>Promising, but yet to be proven </li></ul></ul><ul><ul><li>Licensed spectrum – costs £ € $ ¥ </li></ul></ul><ul><ul><li>30 miles outdoors </li></ul></ul>
  9. 9. 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
  10. 10. 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)
  11. 11. Your opportunities with wireless VoIP <ul><li>Wireless VoIP roaming </li></ul><ul><ul><li>Fast call routing and seamless cell switching </li></ul></ul><ul><ul><li>Cell congestion management </li></ul></ul><ul><ul><li>Coverage improvements </li></ul></ul><ul><li>Integration of complete solutions </li></ul><ul><ul><li>Integration with IP-PBX, gateways, media servers </li></ul></ul><ul><ul><li>Support for voicemail, call transfer, conferencing, email, fax, video, etc. </li></ul></ul>
  12. 12. Your opportunities with wireless VoIP <ul><li>Scalability, availability, resilience </li></ul><ul><ul><li>Growing an enterprise solution </li></ul></ul><ul><ul><li>Related to roaming </li></ul></ul><ul><li>Quality of service (QoS) </li></ul><ul><ul><li>Audio quality affected by delay, jitter and packet loss </li></ul></ul><ul><ul><li>Codecs, PLC, bandwidth management </li></ul></ul>
  13. 13. Your opportunities with wireless VoIP <ul><li>Security </li></ul><ul><ul><li>Wireless channel security </li></ul></ul><ul><ul><li>Wireline security (Secure RTP, TLS, SIPS, etc.) </li></ul></ul><ul><li>Dual mode end user devices or services </li></ul><ul><ul><li>FMC or UMA </li></ul></ul><ul><ul><li>Feature rich, low cost or oriented to a particular market segment </li></ul></ul>
  14. 14. Summary <ul><li>Three key issues of wireless VoIP: </li></ul><ul><ul><li>Mobility </li></ul></ul><ul><ul><li>Simpler ‘last foot’ infrastructure </li></ul></ul><ul><ul><li>Benefits of integration of wireless voice with data </li></ul></ul><ul><li>Radio access technologies include Wi-Fi, WiMAX, HSDPA/HSUPA, TD-CDMA and Flash-OFDM </li></ul><ul><li>Wireless VoIP can be managed, private, public, portable or truly mobile </li></ul><ul><li>Business opportunities exist in roaming, security, scalability, QoS and dual mode operation </li></ul>
