The Summit’s theme, “Beyond Green Buildings – The Triple Bottom Line – Sustainability for People, Planet and Profit,” highlights the benefits of Lifesize high definition video communications for connecting people rather than always needing to travel. Lifesize and RJ Macklin, a Lifesize channel partner, will conduct Lifesize high definition video communications product demonstrations in Booth 505 during the CoreNet Global Summit’s exhibit hours from April 30th to May 1st, 2007. “We work with numerous firms which have offices scattered all over the map and they are always eager to implement new solutions that promise to improve their daily business interactions”, said Bob Dinegar, President, RJ Macklin Associates. “Reducing travel time and costs while minimizing carbon emissions are key drivers in the rapid adoption of high definition video communications, so we are very excited to be demonstrating Lifesize products at CoreNet Global’s Spring Summit.” As time increasingly becomes more valuable, the cost to do business continues to escalate and global initiatives to improve environmental conditions accelerate, companies must adopt solutions and practices that enable greater efficiencies and results. Lifesize high definition video communications allows for dispersed organizations and teams to be located in far-reaching places yet creates an interactive experience as if they really are in the same location. “The true value of high definition video communications is being realized through many new applications that absolutely are improving the way business is conducted,” said Craig Malloy, CEO of Lifesize. “We are pleased that RJ Macklin Associates, given their extensive experience, is showcasing Lifesize high definition video communications products at the CoreNet Global Summit where conscientious businesses are looking for solutions that provide cost savings and productivity gains while also being eco-friendly.” Lifesize was the first company to deliver high definition video communications products. Since then other entrants have attempted to introduce similar offerings or high-end telepresence suites, but Lifesize offers the very best price-to-performance on the market. With Lifesize Room intended for large, geographically distributed participants in multiple locations and Lifesize Team geared for smaller, remote project groups, Lifesize is able to provide organizations of all sizes a high quality, high performance, cost-effective high definition video communications experience.
