The main element of Alcatel's and Fujitsu's HSDPA demonstration system in Paris consists in a real-life 3G/HSDPA Node B provided by Fujitsu according to the same specifications as the ones defined by NTT DoCoMo in Japan.

This real Node B is accompanied by two simulators: one that simulates a HSDPA RNC (Radio Network Controller), and one that simulates a HSDPA handset. As the intelligence and sophistication of HSDPA is located in the radio access equipment (i.e., the Node B), this configuration is well-suited to assess the real-life performance of this key radio element.

In addition, laptops are used to feature, on one hand, a traditional 3G user's experience, and one the other hand, a 3G/HSDPA user's experience.

The main demonstration allows visitors to experience themselves the increased speed and ease-of-use offered by HSDPA (compared to traditional 3G) when it comes to viewing a movie picture or a video. Obviously, the data throughput achieved by the HSDPA system makes the mobile watching of a video a totally different user's experience!
