CellStream, Inc. was founded in March of 1998. We are a telecommunications consultancy, solving problems and educating our clients in the latest technologies.

Our primary clients are the people that help bring all of us the Internet itself, and all its associated technologies. From network and computing equipment manufacturers, to service providers, and data networking companies, to technology experts themselves.  We offer a broad set of Consulting Services.  Our consulting strengths are in inter-networking, network design, network management, network protocols, computing, and engineering, with a focus on converged voice, video, and data services over large, complex, high bandwidth wired/wireless networks and network solutions.  CellStream Consultants bring hundreds of years of cumulative, front-line experience across a range of specific technologies. From Optical to Wireless, and from hardware to software, our experience base can help in all aspects of our clients needs.  We found that along with our skills in consulting, design, and collaboration, that our experience is often invaluable to our clients. This experience places us in a position of mentoring and educating our clients, and led to development of a training curriculum.  Our enhanced Learning Services enable our clients to master technologies and processes in products and services anywhere/any time using Internet technology with minimized training lead times and cost control.  We offer a number of technical training courses [see the Courses Listing page], and we also support e-learning: check out the Online School of Network SciencesTo contact us click here.
