Open Development Program
As part of our open development program intended to provide customers with the ability to use, on our network, devices and mobile applications that we do not sell, in 2008, we published the technical interface standards that the development community is using in order to design such devices. In August 2009, we published updated standards that developers will need to design such devices that can run on the LTE network that we plan to launch in 25 to 30 markets in 2010. In addition, we have certified three independent laboratories to perform testing of third-party devices to ensure that they conform to our technical interface standards in order to operate on our network.
We believe that our open development program will spur innovation, expand customer choices and produce an array of new products for use on our network and, as a result, increase customer connections to our network. Since July 2008, we have certified numerous third-party devices to run on our network.
Additionally, in August 2009, we consummated the formation of a joint venture company, nPhase, which we own equally with Qualcomm Incorporated (Qualcomm). nPhase is expected to facilitate our provision of machine-to-machine wireless communications solutions to a variety of vertical market segments, including healthcare, manufacturing, utilities, distribution and consumer products.
