VoWLAN – opportunities
GSM/UMTS
Enterprise benefits
- Cost Savings as mobile calls are made using VoIP/PSTN
- No new investments: VoIP uses existing IP/WLAN networks
User benefits
- One-phone-solution
- VoIP has better voice quality than cellular
- One address book
Terminal producers and distributors
- New market WLAN-GSM phones
WiFi
Service providers / virtual operators
- New additional service offering enlarges the market
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 WiFi
network which causes dropped calls
• Standards for roaming and interconnect – Who
will be the players connecting all of the WLAN
networks?

Quality Of Service
• No over-the-air QoS
• Low number of calls
• Upstream and Downstream QoS (without
any special client inside the device (need by
Spectralink)
• High density of calls
Low Handoff
• Slow handoff with client
re-associations
• Dropped apps / calls
• Client sees no handoff
• High quality calls
Ease of Deployment
• Channel design and
optimization
• RF Experts needed
• Coordinated Access Points
• No channel design
• No RF experts needed
