Broadband Service Availability - The Bottom Line
> Wireless, satellite, and FTTU not widely available today> In the US, cable modem service is more likely to be
available than DSL• Significant local differences exist, however
> DSL’s worldwide leadership is an advantage> Cable vs. DSL in the US - The Regulatory Effect
• Cable operators are not faced with the same unbundlingrequirements as the telcos
• ILECs serve over 95% of U.S. households, whereas cableoperators serve about 60%
• Nevertheless, cable operators have more than twice as manycable modems in service as telcos do DSL
