VoWLAN: Stop me if you've heard this one...

摘要

Sometimes I find it very helpful when researching a tech story to see how it plays with someone completely oblivious to the inside workings of the telecoms industry. For example, after hearing about voice-over-wireless LAN (VoWLAN) for the first time a couple of years ago - at which time it was being touted as a value-added service for Wi-Fi hot spots in Japan -1 brought it up with an old school chum (call her Rudy) who works in insurance but is a fairly modern telecoms user, with a DSL line at home and a cellphone in her purse.
