Wireless Broadband Networks

Competitive Technology Alternatives

• Lease traditional T-1 and T-3 services from local Telco
• Lease DSL services from Telco: One vendor, Alcatel, offers 3dSL for copper wire infrastructures which uses IP multicast over an asymmetric digital subscriber line (ADSL) with ATM.  From 1.544 Mbps to 512 Kbps downstream and about 128 Kbps upstream. A DSL line can carry both data and voice signals and the data part of the line is continuously connected.
• Lease similar data services from the cable providers
• Lease Teledesic LEOS service (Low entry orbit satellites)  - trying to compete with spare capacity on these satellites
• Implement WLAN - Wireless Local Area Networks in a campus environment with wireless bridges connecting the two LAN segments in two buildings
