3G and WLANs: Complimentary Technologies3G and WLANs: Complimentary Technologies
• Market studies indicate that user demand for high-speed Internet/Intranet applications is greatest in quasi-stationary environments
• Data roaming combines 2.5/3G technologies for wide-area, low-data-rate coverage with WLAN access for localized high-data-rate coverage
• Consideration of the WLAN value chain identifies challenges to sustainable business models for integrated wireless data services

• WLAN business models are immature and evolving
• many small operators, few transactions compared to cellular voice services
• Venues are strong participants in WLAN value chain
• many local property agreements required for WLAN coverage
• large venues may directly manage neutral host access
• venue revenue share complicates pricing strategies
• WISPs and aggregators may offer branded service or unbranded wholesale access

Business Model ConsiderationsBusiness Model Considerations
•The Neutral Host
•Airports and premier venues are leaning towards the “Neutral Host” business model
•venue owns the WLAN network and offers access to all users via roaming, credit card, and/or prepaid access
•venue contracts with neutral host manager for operations and marketing support services
•roaming AAA functions and home-network billing is supported via relationship(s) with clearinghouse
•maximizes revenue generation
for the venue owner
•One-way Roaming
