7. Why is a reprogramable solution necessary? • Too many standards and multimedia requirements • Handset OEM’s if choose the correct combination in HW solution then okay otherwise late in the market • Independence from fixed functionality • Optimize solution for consumer, with geographic context, with target audience (youth, professional etc.), security, with desired applications and connectivity. • Can provide real-time additional features to the consumer • “Pay as you want” model • Enables enhanced service offerings by the Operators, increasing ARPU and reducing churn • Network upgrades for these services are software enhancements • Handset manufacturers reduce development costs, radically decrease time to market, a completely cost effective solution. www.sandbridgetech.com
