Mobile Infrastructure Market Outlook Market’s

Current State:

Mobile subscriptions grew 184M in 1Q10 to a total of 4.8B. 45% of new subscribers came from CHN/IND. Global penetration is now at 70%. Voice remains the main source of revenue for most Operators, however, for many large operators data revenue already exceeds 25% of net revenue Global mobile data traffic surpassed voice traffic in 2009 WCDMA subscriptions grew 39M in 1Q10 to total of 490M Represents only 10% of total subscriptions HSPA coverage available for only 25% of world s population

What’s

Next?

Mobile data traffic has grown 3x in the

past 2 years and is expected to continue to double annually for the next five Broadband to All: Subscribership for Mobile broadband to overtake Fixed line Over 60 LTE network commitments across the world, target downlink speeds up to 100Mbps Infrastructure upgrades Over 5 million legacy BTS deployed today, over 30% will need to be replaced/upgraded in the next few years. Additional demand driven by increased Data uptake and Subscribers
