NSCC Executive Summary CBG Communications, Inc. <br /> enable a minimum of 27 Mbps to be provided upstream on the HFC I-Net. Another <br /> possible method is to convert the HFC I-Net for all sites that are frequent remote <br /> origination sites (such as the Roseville Band Shell)to fully fiber optic connections. <br /> These would then be provided with the same transport equipment and system <br /> recommended for the upgrade of the existing fiber I-Net which would further <br /> satisfactorily enable HD transmissions. <br /> Another alternative for these and other sites on the current HFC I-Net is to provide <br /> "nomadic"DOCSIS 3.0 business class modems on the residential system. This could <br /> also enable HD transport from those current HFC I-Net origination sites. This would <br /> further provide a potential access origination feed from literally anywhere on the <br /> subscriber network. An issue here that would need to be addressed from the beginning of <br /> a renewed franchise, is the need to give these modems priority so that a high capacity <br /> video signal could be delivered without contention or interference from other business <br /> class cable modem users. <br /> One other possibility would be to establish a wireless system for signal transport between <br /> remote locations and CTV's offices. This could be established in a variety of ways. For <br /> example, digital microwave technology could be employed that provides enough capacity <br /> for HD transport. This would most likely require microwave send facilities to be added <br /> to both production trucks, receive antennas either at the Comcast headend or at CTV's <br /> main offices and potentially one or more repeater antennas to be established on tall <br /> buildings or towers throughout the NSCC franchise area. <br /> Another,relatively new way would be to establish a 4G cellular(WiMax or other) <br /> connection for the remote production trucks and the portable mini-mobile facility through <br /> the chosen cellular carrier's network CTV's offices. There is also a relatively new <br /> system that will chain 3G links together to provide the necessary bandwidth. Here again, <br /> priority"quality of service"(QOS)would need to be established so that other cellular <br /> users would not contend for the high capacity, real-time bandwidth needed.
