Business Week’s piece on Intel and Marriott getting together for hotel Wi-Fi and this CNET report on T-Mobile cutting the cost of Wi-Fi access in Starbucks has me thinking that the business models for Wi-Fi access are being set in terms of synergy with existing business. Hotels can use Wi-Fi access as an asymmetric advantage over the competition, while Starbucks has dual use: to draw customers and as internal infrastructure. Instead of seeking out a new killer app, the trend appears to be to leverage current ones: email (the killer app of the Internet) and web access. There’s still up-side as Wi-Fi adoption progresses, but it appears some patience will be required.
