KIRKLAND, USA: Clearwire Corporation announced that it would conduct 4G LTE technology trials in the 2.4GHz to 2.6GHz bands, where Clearwire holds spectrum assets and also test multiple coexistence scenarios between LTE and WiMAX radio technologies.

John Saw, chief technology officer, Clearwire, said: "As we have consistently stated, we remain technology agnostic, but WiMAX provides us with unique advantages to meet the needs of our customers today. Ultimately, consumers don't care about technical acronyms, but they do care about quality and affordable Internet services that work where and when they want, and that's what we're focused on delivering."

Clearwire, in collaboration with Huawei Technologies, Beceem, will test LTE on Samsung Electronics' common base station platform which it currently uses for its mobile WiMAX deployments.

The tests will be conducted in the fall and throughout early 2011 in Phoenix, Arizona.

Saw continued, "The 2.5 GHz spectrum band is universally allocated for global 4G deployments. We believe this commonality will result in a massive diversity of mobile devices and applications, at comparably low costs, due to unmatched economies-of-scale. In a 4G world, wireless coverage is important, but capacity is king."

Cleawire plans to conduct FDD LTE (Frequency Division Duplex) tests using 40 MHz of spectrum, paired in 20 MHz contiguous channels, of its 2.5 GHz spectrum.

It will also concurrently test TDD LTE (Time Division Duplex), in a 20 MHz configuration.

With these trials Clearwire expects to confirm the capability to produce real-world download speeds that range from 20-70 Mbps.

Moreover, Clearwire will also test WiMAX co-existence with both FDD LTE and TDD LTE to confirm the flexibility of its network and spectrum strength to simultaneously support a wide-range of devices across its all-IP network.
