Welcome to CellStream, Inc. - Telecom Consulting and Training!

Welcome to our home on the Internet, where we can not only share information, but also interact with each other. If you are a visitor to the site, there are a number of things to view: our FAQ'sNetworking and Computing Tips, our CellStream Blog, and other fun reading can all be found in the drop down menus above.  The Training menu provides access to our courses, our course calendar, and learning services.  The Consulting Menu provides information on our consulting services and a place to meet our consulting and teaching team.  Registered CellStream folks and our clients will log in using their private credentials to access projects, calendars and discussions.

Thanks for visiting! We always welcome comments and suggestions.

Then you are paying too much!  At CellStream, we offer multi-day hands-on lab classes using your computer/laptop and our state of the art multi-router and/or multi-switch lab systems:

  • We can connect to them from anywhere in the world
  • We leverage the Cloud in our course creation, delivery, and lab experimentation environments.  
  • We use Virtualization technologies to create environmentally friendly lab scenarios
  • We also understand that Instructors also make all the difference when learning technology.
  • Our instructors write and create our courses. These are not shrink-wrapped courses that are taught by someone who has learned the course.
  • Our instructors can explain the "how", and they can answer the "why" questions, because we deeply understand the technology, and in some cases created the technology.

High Cost of Wireshark Training

Learning Network Sciences by examining packets is a crucial skill, and Wireshark is the defacto standard.  We have seen multi-day Wireshark Hands On courses costing over $3000 per student!  Our Wireshark courses are even better quality, more skilled instructors, for a third (or less) the price.  Check out our Wireshark resources and Wireshark Courses here.

High Cost of IPv6 Training

According to the NRO (Number Resource Organization) poll of over 1,500 ISPs in 140 countries, 45% reported struggling to find IPv6 knowledgeable staff, and over 50% said the costs were too high! Our Hands On IPv6 course has been completely revamped and is available, Contact Us regarding the course, or view details at the CellStream Courses Listing.

Telecom Italia reported at the November 2011 IPv6 conference that one of their biggest challenges was to get their staff trained on IPv6. Make sure your organization has a plan to train their staff, not just their network engineers on IPv6. You can find IPv6 resources and training classes here.

Value of Training

Companies that have successful training programs outperform the market by more than 45% while companies that do not underperform by 22% - Americam Society for Training and Development

High Cost of Certification

If you are a rural service provider or a small communications centric company, certification costs are through the roof.  We offer a much more affordable solution.  Click here to learn more about what we call Self Certification.
