Nokia Siemens Networks previously released a video demonstrating the gigabit speeds in delivered in a test environment last month. At next month’s CTIA show in N’Orleans, it’s going to recreate the demo live. The technology behind these blazing speeds is the same as Clearwire plans to deploy in its LTE network. This next generation “LTE Advanced” variation is not due for commercial roll-out until late this decade, but incremental advancements are being incorporated by carriers today. [Source GigOM]
