Network Considerations


The CADE product suite has been designed to run redundantly and is able to be placed on the computer that works best for the unique characteristics of a specific interactive broadcast environment.  CADE applications run:

  • Stand-Alone or Multiple Computers
  • In Any Combination
  • Over Any Internet Connection


Video Distribution Network

CADE delivers interactive, multi-media content via satellite, video conferencing and Internet/intranet networks simultaneously. So whether your message is directed towards your sales force using business television, to your key employees using video conferencing, or to the world using the Internet, CADE is the only solution you need.

You Decide 

The choice of network design is yours. You decide the most effective way for your organization to take advantage of the CADE solution, with a centrally located presenter or instructor linked interactively to your remote employees.

With the CADE products, you can choose to use capabilities you already have, or choose to deploy new capabilities. You choose the most effective way for your organization to enjoy the benefits of one of the CADE products.

Because each organization is different, the CADE products are designed to support any broadband enterprise network–from business television and Satellite to videoconferencing and corporate intranet. With CADE, you can tailor the solution to your environment…with the resulting solution built on your original network investment.

Easy Integration

In today's world, most large organizations and companies have already invested in a number of different network configurations, including satellite, fiber, and copper wire. That’s why the CADE distance learning applications are designed to work with any network, allowing you to step up to interactive distance learning by expanding – not replacing – your existing network environment.

Network Topology

The CADE systems can use a variety of different network technologies to deliver the presentation or course to the participants. See below for the choices you have with the CADE product suite.

The students' (or participants') audio and data are returned to the Studio using your LAN, the Internet, or a combination of the two. No telephone call is required, since CADE uses VOIP (Voice Over IP) on your existing network to enable all participants to interact with the centrally located presenter.

Delivering the Message with CADE

Business TV

CADE can turn your one-way Business Television Network into an interactive Distance Communication or Learning Network. You can already transmit the video and audio from your studio to your remote sites' classrooms. By integrating CADE components, you can add audio and data interaction to all your broadcasts.

Each classroom or meeting room is equipped with CADE’s interactive remote controls, and microphones. These are linked through the CADE Virtual Classroom software, which is used to send the response data and student voice back to the presenter in the studio.

The student’s voice, as well as question and answer data, flow through the Virtual Classroom PC's local internet connection.

Satellite TV

Satellite is the most cost-effective solution for larger corporate networks. The instructor's audio and video are sent over satellite with the information from each remote site returneded via an internet connection. There are a number cost effective of choices for Satellite providers and services. DBS (Direct Broadcast Satellite), C or Ku band satellites, or a bi-directional VSAT (Very Small Aperture) system.  DBS satellites can be a good choice to simplify the remote site installation and support.   Other satellite networks are typically less expensive for transmission time, but can be more costly and burdensome to install and maintain.

If you are not familiar with satellite transmission, Learn.Net is prepared to work with you to find the best choice for your planned use of the CADE in your organization.


Many companies already use an internal videoconferencing network, based on ISDN or T1 circuits, to conduct meetings. Depending on your planned usage of CADE, you may want to integrate CADE with your videoconferencing network . This approach can get your organization up and running rapidly, delivering highly interactive distance learning communications or classes to your existing remote sites.

At the remote sites, each meeting room is equipped with a PC, CADE Virtual Classroom software, microphone and optional CADE remote controls with built-in microphones. The remote controls are used to send responses to instructor/presenter asked questions and the participant's voice back to the studio.  With CADE your enhanced videoconferencing network can be used reach and train employees with video and full-duplex audio managed by the presenter, as well as 2-way data so you can poll and measure student participation.

LAN / WAN and Intranet

Another effective choice for content delivery may be to use your organization's intranet. You may already have the foundation needed to deliver interactive content directly to classrooms or any students' desktop PC. With CADE's Virtual Classroom, you can receive streaming audio and  video from the Studio at any PC connected to the network.  Because streaming video technology can require significant network bandwidth, this approach may not be for every organization. But if your network is streaming-video capable, it can be the least costly approach to delivering multimedia, interactive content throughout your organization.  Learn.Net can provide information to your network staff to help determine if this is a good choice for delivering content. As with other delivery choices, your network also returns student audio and data to the Presenter.

High-Speed Internet

With the growth of the Internet has come the increased availability of low cost, high speed internet connections. The choices are varied: (1) DSL or Cable Internet connections with speeds in excess of 1MB/second or (2) Internet via satellite with compact, low-cost, user-installable digital satellite systems, such as Hughes DirecPC® , which provides Internet download speeds of up to 400 kbps. These latest advances in Internet connectivity for your remote offices can be used with CADE to deliver fully integrated (video, two-way voice and data) PC or classroom based distance learning capability.

Remember that all of these choices can be combined simultaneously to provide interactive distance communication throughout your entire organization — depending on your needs and capabilities. Contact Learn.Net for an in depth discussion of how to integrate CADE with your network.
