1996 – “It Was A Very Good Year”
• Little Direct Fiber Access
• T-1 Rates Justified $10K Wireless Links
• 38 GHz Spectrum
• Technology And Faith Solves All
Our Industry’s Response
• Revive an Old Technique
– Point-to-Multipoint
– Millimeter Bands
• Make Promises
– Low Cost
– Easy Deployment
– Efficient Spectrum Usage
• Faith and Technology

Paul’s Request to Us
• Equipment (on a cost per MBIT basis)– OC-3 links loaded
• Installation– One install serving multiple customers
• Ongoing operation– All on net
Lowest Cost of
Real Solutions – What Can Industry Offer?
• Cost-effective High Capacity– Customer Trend– Shared and Dedicated 45 Mbps to OC-12– Star, Trunk, Ring Network Configurations– Modular Capacity Chunks T1 and up– In-Building Interface and Distribution– Proactive Network Management
• Multiple Access Over-the-Air– Feature of High Capacity Systems– Probably lower frequencies– Maybe optical
