NetworksWireless carriers face slowdown of subscriber growth.
As the global wireless industry convenes today for its biggest event of the year, the 3GSM World Congress 2007 in Barcelona, Spain, carriers participating in the event face a major challenge: how to maintain revenue growth amid a dramatic slowdown in new handset subscribers. At the 3GSM event, manufacturers are expected to show their latest products, ranging from high-end music-enabled wireless handsets and smart phones that are designed to appeal to sophisticated users in developed regions, to Ultra Low-Cost Handsets (ULCHs) that are targeted at low-income users in the third world.
