The Roaming Opportunity
• Roaming revenues to double from 2010 to 2015 (Visiongain, Informa)
• Mainly driven by data roaming revenues
– Global data roaming traffic will jump from 688 million MB in 2011 to 1.9 billion MB in 2015 (Informa)
• Meanwhile, “LTE is the fastest growing mobile technology ever” (GSA)
• So what does that mean for LTE Roaming?
– “Without it, mobile operators will be at a serious disadvantage in generating the revenues required to recoup their investment in LTE technologies.” (Informa)

Challenges • Building roaming connections will require significant time and cost • Need new IP interconnects to be created • Complexity of managing full-mesh topology • Interoperability between Diameter implementations • Interworking with 2G/3G networks

The Diameter Dilemma Time to Market, User Experience, Profitability

Result: difficulties in
• monetizing the booming data roaming opportunity
– LTE users will expect the same user experience when roaming
– (regulated) low data roaming tariffs will create enormous demand
– Attract 3G users by offering 4G speeds when roaming
• monetizing the national LTE opportunity
– Spotty initial LTE coverage will generate national LTE roaming opportunity to offer consistent user experience
• Need to ensure LTE profitability
– roaming cost are unnecessary high, while roaming prices plummet
