Test mobile

Aeroflex says its TM500 test mobile supports the 3GPP W-CDMA release 8 dual cell HSDPA (DC-HSDPA) feature.

DC-HSDPA extends the resource use and spectrum efficiency of existing W-CDMA networks by providing an alternative method to HSPA+ to increase peak data rates in the downlink to a maximum 42 Mbps.

This is achieved by enabling handsets to take advantage of two adjacent 5 MHz channels on the same node B simultaneously, to create 10 MHz downlink bandwidth.

Unlike HSPA+, DC-HSDPA delivers a peak data rate of 42 Mbps without the need for MIMO spatial multiplexing and the associated, base station (Node B) hardware and antenna upgrades this can entail.

As a result, DC-HSDPA facilitates improved network efficiency and load balancing through better resource allocation and frequency selectivity.

From HSDPA to HSUPA and HSPA+ to LTE, the device offers all the capabilities of a mobile terminal with test functionality for 3GPP verification, validation and optimisation.

It provides low-level handset UE control and configuration flexibility, combined with the detailed measurement data required by infrastructure engineers to diagnose issues.

The test set-up not only provides the ability to check a base station and network against a single mobile, both in the lab and over the air, but also supports multi-UE configurations, enabling base station and core network designs to be load tested, stressed and optimised to ensure that robust, flexible and high-performance solutions are delivered to network operators.
