Company Will Showcase Its New Mobile Convergence Solutions


SAN JOSE, CA--(Marketwire - October 18, 2010) -  AltiGen Communications, Inc. (OTCQX: ATGN) (PINKSHEETS: ATGN), the leading provider of software-based Unified Communications solutions, today announced it will be exhibiting its new mobile convergence solutions at 4G World™ 2010. The trade show is being held at the McCormick Place in Chicago, Illinois, October 18-21, 2010. AltiGen Communications can be found at booth #142.

Sponsored by the Yankee Group, 4G World™ is the largest event in the world covering the entire ecosystem of next-generation technologies that enable the mobile Internet revolution, including mobile network infrastructure, advanced devices, applications and content. The event is expected to attract more than 8,000 attendees, including executives, thought leaders, operators and innovators -- and others who are shaping the future of the 4G ecosystem.

AltiGen will be showcasing MaxMobile, which is a next generation mobile convergence application for mobile network operators (MNOs). MaxMobile enables MNOs to deliver complete business telephony capabilities on smartphone devices, uniquely addresses the business communications requirements of the mobile workforce. As an all software solution, designed as a native application for iPhone, Android, BlackBerry and (in 2Q11) Windows Phone 7 smartphones, MaxMobile converges all business communications on a single device. From a business perspective, MaxMobile improves employee productivity while eliminating the need for a separate desktop phone. MNOs are able to drive new business service plan revenue by replacing redundant land line service with MaxMobile enabled smartphone devices. 

"The focus of the 4G World™ 2010 trade show is empowering mobile networks, applications and services," said Niel Levonius, AltiGen's Director of Corporate Strategy. "With the rapid proliferation of smartphones in business, and a projected one billion mobile workers globally by 2014, mobile network operators will have the opportunity to drive significant new revenue streams. AltiGen's new mobile convergence solutions enable MNOs to address this opportunity and 4G World is the perfect venue to introduce our solutions."
