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

• 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

5
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?

Why is Meru Networks The Leader for Pervasive
Deployments?
Stand Alone/Hot-Spot / Departmental
Pervasive cellular
Requirements For Enterprise VoIP Mobility Other Wi-Fi and WLAN Switches Meru Wireless LAN
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
