Clearwire's 4G LTE Network
Clearwire's 4G TDD-LTE Network will be unlike any other in the wireless industry. With 160MHz of wireless spectrum on average in some of the largest markets in the United States, Clearwire will be able to deliver more capacity to high-density, high-demand markets than other wireless networks. In 2012, IDC highlighted Clearwire's spectrum position in a report and noted that other wireless companies are already seeing a time when they reach full capacity on their networks.
The Clearwire LTE network will target densely populated, urban areas where demand for mobile broadband is high. Our 4G LTE network will use Time Division Duplex (TDD) LTE technology and reuse our existing all-IP network architecture, which will yield savings on capital expenses.
"This is the future of mobile broadband," says Dr. John Saw, Clearwire's Chief Technology Officer. "We believe our LTE Advanced-ready network design, which leverages our deep spectrum with wide channels, can achieve greater speeds and capacity than other networks. We believe Clearwire is the only carrier with the unencumbered spectrum portfolio required to achieve this level of speed and capacity in the United States."
"In addition, the 2.5 GHz spectrum band and TDD-LTE technology that we have chosen has rapidly become a common configuration worldwide for 4G deployments, creating a potentially robust, cost-effective and global ecosystem that could serve billions of devices," Saw added. "We anticipate that the economies of scale derived from this global ecosystem will act as a catalyst for the development of thousands of low-cost devices and applications."
LTE Advanced is a 4G technical standard that calls for peak download mobile speeds of at least 100 Mbps, which far exceeds today's commercial networks. Our LTE network will be "LTE Advanced-ready" meaning that it will use an ultra-high-capacity spectrum configuration that is superior to the typical configuration of the slower, more capacity-constrained commercial LTE network designs in the United States today.
This will include the use of multicarrier, or multichannel, wideband radios that will be carrier aggregation capable. Carrier aggregation is a key feature of LTE Advanced that will enable us to further leverage our vast spectrum depth to create larger "fat pipes" for deploying mobile broadband service.
Global Network Ecosystem
Clearwire, together with some of the largest wireless carriers in the world such as China Mobile and Softbank, is a founding member of the Global TDD LTE Initiative (GTI) which aims to bring together leading industry partners to steer the TDD- LTE ecosystem as a major standard in mobile broadband technology and drive the development of next generation mobile broadband networks. Member companies that currently support more than a billion subscribers on their networks believe that a global LTE standard has the potential to achieve significant economies of scale and serve hundreds of millions of customers worldwide
