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

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 WiFinetwork which causes dropped calls• Standards for roaming and interconnect – Whowill be the players connecting all of the WLANnetworks?
