Introduction to Broadband Networks

Network Implementation Process; Design, Installation, and Certification

Broadband Networks are high bandwidth, and based on RF distribution systems. These networks initially carried multiple television signals (channels) in modulated format (pixel, chroma, audio). Each channel was 6 Mega-Hertz wide. New modulation methods for digital high definition channels can compress multiple analog channels into one. Each Channel can be subdivided to carry other types of information besides video as long as they are modulated. Data is a typical example; the cable companies provides that service to the consumer on regular basis, and depending on the modulation method, and compression, can carry several times the bandwidth in data-rate. Channels can be grouped together to form much larger blocks, when needed, to satisfy high data bandwidth demands. Another advantage of broadband networks is division, or segregation of services that are non-switched. In baseband networks (IEEE 802.3 or Ethernet type networks), the services share the same single channel (packet network), and are not segregated, but prioritized in the TCP/IP realm. In Broadband Networks, you can implement multiple segregated TCP/IP networks, coexisting within the same RF network.

Broadband network infrastructure is composed of active elements (such as amplifiers, and power supplies), and passive elements such as cable, directional couplers, taps, and signal conditioning devices.

Full duplex communication is possible by bridging the upstream and downstream at the head-end (CMTS). The head-end also provides the connection to the outside world through various communication media (land-lines, microwave and satellite links, etc.). 

We will work with you to define your requirements for a redundant, well-planned Broadband Network (RF distribution system) capable of carrying multiple services that will serve your needs for many years to come. Our expert crew will install the network, and our engineering staff will use state of the art instruments to fully test the system. We will provide you with first class, detailed documentation that includes design, routing, system certification, and complete distortion test results (Carrier to noise, Composite beats, and second order).

We can train your employees to maintain the system, or offer you options should you wish to use our maintenance services. Of course, we warranty our work against material, and workmanship defects for at least one year.
