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

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 portalsHandset e-mail and IM erodes SMS, MMS
“Free” VoIP over WiFi / WiMax / Bluetooth erodes voice trafficBluetooth and WiFi on handsets attacks everything
WiFi and wireless broadband attack 3GDVB and DABS broadcast compete with streaming media
3rd party media portals (e.g. iTunes) compete with operatorsOutsourcers and service providers attack value-added applications
Recommendations
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.
