Global telecoms operators will lose an estimated 11.6 per cent of turnover, equating to $170bn annually, through fraud and other types of revenue leakage in 2005, compared to 10.7 per cent in 2004, research has claimed.
A report from telecoms analyst Analysys found that major sources of revenue loss continue to be fraud, credit management, least-cost-routing errors, interconnect/partner-payment errors, and poor processes and systems.
Analysys revealed that fraudulent activity, in particular, has risen since last year and is now the single largest area of revenue leakage at 2.7 per cent.
The report, commissioned by revenue-assurance company Azure Solutions, estimated that fixed-line operators continue to lose less than their mobile counterparts, and highlighted strong regional differences.
Operators in North America, Central and Latin America, the Middle East and Africa, in particular, suffered from more "revenue leakage" than the global average.
Danny Dicks, principal analyst at Analysys, said: "This is the fourth year we have carried out the research and it is clear that operators are becoming more realistic about loss levels.
"Consequently many operators now have dedicated revenue-assurance teams and are investing in external help in order to reduce losses."
