ICO and Clearwire to Conduct Mobile Video Trial.

Initiative Will Focus on Feasibility of Delivering Mobile Video From Satellite as Part of Mobile Triple Play

RESTON, Va. & KIRKLAND, Wash. -- ICO Global Communications (Holdings) Limited (NASDAQ:ICOG) and Clearwire Corporation (NASDAQ:CLWR) today announced a joint agreement to collaborate on one of the industry's first mobile video trials. The collaborative effort is at the forefront of the intersection between two-way wireless broadband and satellite connectivity, and will focus on increasing the value and cost effectiveness of delivering an advanced interactive mobile video service to consumers. In addition to testing mobile video broadcast, the trial will also examine the feasibility of utilizing Clearwire's 2.5 GHz spectrum and ICO's 2.0 GHz spectrum more efficiently. The ICO trial with Clearwire is expected to begin in early 2008 in Raleigh, North Carolina, and ICO is also planning a similar trial in Las Vegas, Nevada.

"Our next generation wireless personal broadband networks are built to deliver data, voice and video over a single network," said Scott Richardson, chief strategy officer for Clearwire. "Working with ICO to trial an interactive mobile video element that can potentially enhance our service offering not only in areas where we don't intend to build our own network, but that can also potentially enhance the use of infrastructure and spectrum where our coverage overlaps, makes a lot of sense."

"Mobile two-way video, advanced interactive navigation, plus emergency calling and messaging becomes an even more compelling value proposition when integrated with a wireless broadband network such as Clearwire's," added Tim Bryan, chief executive officer for ICO. "We are well positioned to be the first provider of next-generation mobile satellite services, and we have a clearly differentiated offering by leveraging integrated satellite and terrestrial networks to deliver advanced consumer mobility services."

For the trial, ICO will integrate its Mobile Interactive Media (MIM) suite of services with the Clearwire broadband network. ICO MIM is a converged mobile media service which delivers a wide variety of consumer entertainment and communications services, all based on ICO's next-generation satellite and terrestrial wireless communication capabilities. For the trial, ICO MIM will provide multiple channels of high-quality mobile video to large-screen user devices. Alcatel-Lucent has been chosen to supply the system architecture and design based on mobile multimedia DVB-SH open standard, and Hughes Network Systems has been tapped to provide the device as well as the interactive elements based upon the proven GMR standard.
