Dr. Iain Stewart Vice President of Engineering - CTO
Dr. Stewart originally trained as a Physicist and Mathematician and has 28 years of experience in most aspects of system software development, telecommunications and radio transmission. He was awarded his Ph.D. in physics for developing a technique for measuring the conductivity of doped Germanium over a range of temperatures to 4.2K and developing the mathematical model necessary for the convergence of three theories of electrical conduction.
In the 80’s, he wrote operating systems, middleware and data-communication protocols for major international corporations including Bell Labs. In the early 90’s he was able to apply this expertise to research in data transport overinterference-impaired radio channels which was then used for the evaluation of early digital cellular systems. During the last 12 years he deployed a CDMA network in the USA - and then designed, engineered and deployed nation-wide LMDS networks in the Philippines, Switzerland, & Holland as well as a long-distance fiber network in Poland.
He was also involved in a $7.8B cable upgrade in Germany. Using a proprietary technology, Iain currently works with major US, European and Latin American mobile operators to reduce their cell-site backhaul requirements for GSM and UMTS as they migrate to apseudowire underlay. All networks depend for their profitability on their efficient use of bandwidth while providing the service differentiation necessary for a wide variety of high-value, real-time services such as VoIP and video conferencing.
Dr. Stewart’s mathematical background helps ensure the optimum use of resources while preserving service integrity. His experience in developing communications protocols at every level of the OSI protocol stack helps guarantee network integrity, while his practical experience with the deployment of RF systems helps safeguard transmission integrity.
Chris Watson Chief Applications Engineer
Chris Watson has recently deployed three WiMax systems in Europe. His experience in WiMax is extensive, and he is highly sought after to work in the WiMax arena. His projects are reviewed below. Chris Watson operates a high-technology services company based in St. Louis, MO.
For the past 20 years, Watson has specialized in international voice and data switch developments and operations of switching with long distance networks on a world-wide basis. Over the last year, he has developed and installed numerous VOIP and wireless networks with telephone companies in US, Southeast Asia, and Central Europe which has positioned him as a leading provider of technical wireless services for wireless “WiFi” and “WiMax” applications. The most recent system release, developed and designed by his group is Qfone- SIP softphone device (computer telephone), similar to Skype with a carrier grade VoIP network deployment under pre/post paid operation infrastructure.
Another US development included the “Country Roads” wireless network supplying rural community wireless internet and VOIP services in the rural and urban communities, based on a new communications technology called “WiMax”. WiMax is a wireless protocol, developed in conjunction with Intel Corporation at a cost of more than US $3 Billion, and by Motorola at billions more. Mr. Watson began engineering and deploying Wimax systems into commercial markets early in 2005.
Mr. Watson has completed the planning and deployment of an extensive integrated Carrier VoIP networkwith wireless infrastructure designed in 6 capital cities with an additional 24 smaller cities. The development allowed fast deployment for last mile interconnection with the ability to make available enhanced technology products with reduced cost in hardware, increase speed of product to customer and allowing the carrier to control its network and quality of service to the customer.
