Lifesize HD adds 'new dimension' to conferencing at Mercy Health Aug 25, 2010 | Staff New, high-powered mobile devices, which put sharp screens and fast processing in the hands of employees nearly everywhere, represent the biggest growth opportunity for videoconferencing, according to Malloy and others in the industry. Analysts expect the market for room-sized meeting systems to grow slowly over the next few years because of high costs and space requirements. Mobile devices are quickly proliferating and offer a way for more workers on the road to participate in video meetings. Cloud-based services are also a growing trend in videoconferencing. Smaller businesses are demanding these services now so they can save the cost of infrastructure, but large enterprises will also embrace the cloud, according to Frost & Sullivan analyst Roopam Jain.
