Voice over WiMax: Minimise the Risks
New offerings like Voice over WiMax often prompt a lot of concern from revenue assurance people. The trick is to remember that there will be a few different risks whilst many of the fundamentals will be unchanged. So monitoring for indicators of fraud or checking completeness of EDRs are basically the same for Voice over WiMax, but some of the technology used may differ. This article about the risks of leakage for Voice over WiMax scores 9 out of 10 for being well-written and balanced. It would have been 10 out of 10 apart from the fact that the author is from ECtel, ECtel sell IP probes, and the major piece of advice is that people should buy IP probes...

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.
