VoWLAN Phone Key Features

• VoWLAN (Wifi-phone)
• Low-cost phone which utilizes the WLAN and VoIP
  infrastructure not a GSM/CDMA handset
  or cellular-WLAN combo phone
• Significant market interest in potential
  applications
• mobility for traditional vertical markets
• mobility for enterprise desktop and residential /
  DECT or cordless phone replacement
• Solutions in the market today are limited
  (Spectralink, Symbol), proprietary and expensive
  limited to niche vertical markets
• Significant barriers to adoption exist
• cost must be comparable to DECT / cordless phones
• low power consumption minimum 4 hour talk time,
  80 hour stand-by time
• Standards 802.11e (EDCF), 802.11i (WEP, TKIP,
  AES)
• Targeted integrated silicon solutions are needed
  Broadcom, Agere, TI, etc

Increased device capability means VoIP is now a
software-only function, using a fraction of the
available processing power

Residential Voice Gateway Segment Trends

• IP Phone/Phone Adapter
• Originally low featured trend is now toward a
  complete voice feature set equal to that of RGW
  products (fax support, Supplementary Services,
  provisioning, etc)
• Interfacing to home routers in addition to BB
  modem where many customers already have deployed
  a home routing solution in advance of subscribing
  to VoIP
• Residential Voice Gateway (RVG)
• Rapid movement toward WLAN solution for routing
• BOM cost continues to be the 1 driver for
  development
• QOS becoming a more significant requirement
• Automated provisioning, billing, support
  transparent to end customer
• VoWLAN (Wifi-phone)
• Trend is moving toward dual mode solution
