Liquid Radio, Bandwidth Optimizer Technology

In the event Cellular Telecommunications and Internet Association (CTIA) Wireless 2011, Nokia Siemens Networks introduces a new architecture for mobile networks.

Unlike the previous technology, the technology called Liquid Radio is able to drain the capacity of broadband to the places most in need. Thus, network resources will be more efficient because of the distribution and redistribution of capacity based on user needs.

"Liquid is not confined, so it can flow to fill any gaps or spaces," said Thorsten Robrecht, Head of Product Management Network Systems, Nokia Siemens Networks, as quoted from the Connected Planet, Wednesday, March 23, 2011.

In the same way, Robrecht mentions, architectures Liquid Radio eliminate all barriers in the traditional mobile broadband network. "It's rewarding to cope with fluctuations in traffic due to the movement of users on the network," he said.

Robrecht explained, the core of the Liquid Radio is the ability to respond to fluctuating demand in the current network with a technique known as 'baseband pooling'.

This approach focuses resources needed to perform processing functions that are common to every base station in a particular area. 'Baseband pooling' help realize the sharing of resources is more cost effective in a wide geographic area.

This architecture uses Multiradio Flexi Antenna system based active antenna technology that combines the antenna and the radio parts in a container with a functional, built with a dedicated power amplifier for each antenna element.

Active antenna allows beamforming (the formation of wave files) - which focuses on a particular radio connection and directs it to specific users - as well as handle multiple technologies in one unit.

Together with other layers of coverage provided by the site configuration macro, pico and micro, beamforming enables capacity directed to where the desired user, resulting in additional capacity by 65 percent.

"We predict, the demand for increased network capacity up to 1 GB per user one day," says Robrecht. "If it happens, it does not just require an investment of very large networks, but also the unique combination of a variety of base station sites for a wide range of areas," he said.
