This capability is relatively simple and inexpensive to implement, and in fact, was provided as part of the functionality of the TEEN Network. This is the must-have service. For many educators it is more important than the video service. The 10 MB Ethernet capability can be used for administrative functions, such as attendance, payroll, record keeping, etc. Schools see this as a means to centralize their data processing functions and to reduce MIS expenditures.
Internet is almost self-explanatory.
It is the 1990s' version of the encyclopedia. Commercially available and proven RF modems have greatly simplified the simultaneous transmission of 10 MB Ethernet, Internet and multiple full motion video services. The WAN can approach a 200-mile service radius and be fully symmetrical with full 10 MB throughput. A central headend collects the inbound data carrier from each LAN and uses a frequency translator to convert the data package to a high frequency outbound carrier returned to each site's bridge. The IP router directs Internet access to LAN users via their IP address, while other protocols are directed by the Ethernet pacer.
