Wireless Voice: Still the Dominant application VoIP over Wireless Cellular replaces fixed lines Cellular voice trends
Infrastructure costs 4x basic wireless networking to support VoIP
Only 5 percent terminations
But 80 percent of employees will use it occasionally, e.g. SOHO, Skype...
Costs fall, bundles grow
“ Free” voice and data
Operators look for value-added services to preserve the “cash cow”
Operator voice profits fall
Shift from fixed to mobile continues
Mobile replaces corporate PBX
Requires customized contracts
Indoor coverage limitations
May lose some PBX features
Convergence: Carriers and Services Access Cellular WiFi hotspots Fixed telephone Fixed Broadband Broadcast Wireless Broadband Network Services Customer care Billing and support Directory services Messaging, e-mail, voicemail Authentication Presence Content and media Games Music Video Ring tones News Payment Bundling — multiple vertical services, but little integration Convergence — horizontally, integrated service combinations
Mobile Operator Disintermediation Internet access and browsers on phones sideline WAP and operator portals Handset e-mail and IM erodes SMS, MMS “ Free” VoIP over WiFi / WiMax / Bluetooth erodes voice traffic Bluetooth and WiFi on handsets attacks everything WiFi and wireless broadband attack 3G DVB and DABS broadcast compete with streaming media 3 rd party media portals (e.g. iTunes) compete with operators Outsourcers and service providers attack value-added applications
Aggregate mobile and remote access technologies into consistent services for users — independent of the access technology.
Test WLAN-enabled cell phones to assess their impact on the future direction of in-building communications.
Explore wireless VoIP for special cases such as campus environments with low employee density.
Prepare for the evolution of the network infrastructure.
Explore bundled and converged offerings, but resist to operator pressure for value-added services that don’t match enterprise needs.
