  1. Actually the definition of fraud may also morph. In the past, simultaneous usage of a user ID would be considered fraud since a user is often billed on a flat monthly subscription (MRC). But, Earthlink has taken a unique approach with its municipal Wi-Fi deployments. Rather than considering simultaneous usage as fraud, they are charging customers for the privilege. The rationale is that with the mobility afforded by muni Wi-Fi, simultaneous usage is bound to happen, for example when you leave your desktop logged in at home and walk out the door to take a call with your Wi-Fi enabled handset. BTW – the charging schemes with overlapping blocks of usage are not trivial, and provide their own revenue assurance and auditing challenges.
