長途通話市場中無線技術之影響

The Wireless Impact on Long Distance Markets is a highly-focused research study that examines the market shifts that have impacted long distance and wireless calling patterns. This report presents several metrics which track the dramatic shift in telecommunications usage, including residential wireline long-distance minutes of use, residential wireless long-distance minutes of use, the distribution by time of day of wireline and wireless residential calls, call duration statistics, and prices.

Between 1998 and 2003, residential use of wireline LD has declined from 97 minutes per month to 52 minutes per month. Over the same five years, residential wireless usage increased from four minutes per month to 34 minutes per month.

This migration will continue as wireless providers gradually take a larger share of the LD pie. Two factors contribute to this trend:

• Residential customers are using the free nights and weekends to make their LD calls.
• Customers will substitute wireless services for wireline services.

Those that opt for only a wireless phone will not have the option of putting calls on the wireline network. Their only option will be wireless, which will drive the wireless LD usage still higher.
