BOONTON, NJ – Overall telecommunications services revenues are expected to grow at a compounded rate of nearly 13.8% during the next few years, reaching $3.7 trillion by 2015, says The Insight Research Corp.

The worldwide telecommunications industry is expected to continue expanding over the next five years, as growth of wireless services in emerging markets offsets the spending slowdown in the advanced economies, says the firm.

Wireless is expected to make the strongest showing, while wireline will follow a distant second.

Nearly all growth in both sectors is expected to occur in broadband services, with wireless broadband service revenues expected to grow at a compounded rate of more than 62% over the forecast period; wireline broadband services is expected to grow at a 6% rate.
