Multi-user emulation on mobile devices enables network load testing and optimization.
By emulating a single device, the Aeroflex TM500 DC-HSDPA test equipment provides low-level control and configuration, combining the detailed measurement data required by infrastructure engineers for rapid diagnosis of engineering issues. However, testing a base station with a single phone is not enough. Programming algorithms must be optimized, and the base station must be tested under load.
The TM500 DC-HSDPA Multi-user now supports the ability to test a base station and network configuration against a multi-mobile configuration. The TM500 allows base station and core network designs to be load-tested, stressed, and optimized to ensure robust, flexible, and high-performance products are delivered to network operators.
“The Aeroflex TM500 family is continuously evolving to keep pace with the roadmap standards that wireless network operators follow,” said Tim Beard, WCDMA product manager for Aeroflex Test Solutions. “We expect the new DC-HSDPA standard to be widely adopted by operators looking for ways to improve performance and extend the life of their existing networks at minimal cost. The TM500 is the first mobile test equipment with multi-UE capability for DC-HSDPA functionality.”
Aeroflex TM500 Family:
The Aeroflex TM500 mobile tester family has established itself as the "gold standard" for cellular infrastructure equipment manufacturers worldwide. Manufacturers are required to test network equipment under real-world operating conditions. All major infrastructure vendors, as well as most femtocell manufacturers, currently use the TM500. The Multi-UE DC-HSDPA model is the latest addition to the TM500 family, offering support for 3G and 4G HSDPA standards via HSUPA, HSPA+, and DC-HSDPA to LTE. The TM500 provides all the capabilities of a mobile phone or mobile phone suite, with advanced testing functionality for comprehensive 3GPP verification, validation, and optimization.
Dual-Cell HSDPA
extends the resource utilization and spectrum efficiency of existing W-CDMA networks, providing an alternative to HSPA+, boosting peak downstream data rates to a maximum of 42 Mbps. This is achieved by allowing mobile devices to utilize two adjacent 5 MHz channels on the same Node B simultaneously, creating a 10 MHz downstream bandwidth.
DC-HSDPA offers a maximum data rate of 42 Mbps without requiring spatial multiplexing MIMO (multiple-input/multiple-output), thus avoiding potentially costly hardware upgrades for the base station (Node B) and antennas that spatial multiplexing might entail. DC-HSDPA improves network efficiency and load balancing selection through resource and frequency allocation. DC-HSDPA also enhances Quality of Service (QoS) for users in poor environments where MIMO is not necessarily an option.
