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!

Mobility wireless VoIP gets you unplugged!

• Two types of wireless VoIP
• Enterprise wVoIP indoor via Wi-Fi
• Public Internet wVoIP via Wi-Fi / WiMAX
• Dual mode access technologies / phones

FMC
UMA
Fixed / mobile convergence
Unlicensed mobile access
Private pico-cell indoor
Public cells outdoor
VoWiFi indoor
GSM / CDMA outdoor

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.

7
Integration of voice with data applications

• Its 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

Wireless VoIP makes money
In building (DoCoMO, Passage)
In building public areas (BT Fusion)
VoWiMAX (Korea telecom, Sprint)
IMS-based services (Super3G)
In building fixed (Skype/ Siemens DECT)
DIY cellular (Skype on Motorola phone)
Public areas (Vonage/ Boingo)

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.

12
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

13
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

14
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
