DRESDEN, Germany-Two companies announced High Speed Downlink Packet Access test products yesterday.
Radioplan announced a commercial simulation and optimization toolset for W-CDMA’s HSDPA technology.
WiNeS 3.1 is the latest version of the company’s third-generation optimization solution. The new version includes several updated vendor-specific RRM algorithms, import and export capabilities for Motorola Inc.’s Netplan and Xenicom’s Odyssey planning tools, support for neighbor list optimization, support for a variety of languages, and several new analysis functions.
The company plans to showcase the solution at IIR’s 3G Networks conference next month in Lisbon, Portugal.
UbiNetics also announced new test products for HSDPA technology. The company’s new Multi-UE option is an extension of its TM500 HSDPA Test Mobile. The product will allow infrastructure vendors to stress-test early HSDPA networks before commercial rollout, said the company.
The Multi-UE option allows a single TM500 to concurrently emulate up to 32 individual mobiles. Several TM500s can be connected to simulate more mobiles in one HSDPA cell, said the company.
“HSDPA optimizes the use of available power and bandwidth by varying the transmission to mobile phones depending on individual channel conditions. Overall performance is critically reliant on networks, making fast and accurate decisions on which mobile to serve at any particular time, based on channel quality metrics returned by the mobiles,” said Philip Windred, senior vice president for test and measurement products at UbiNetics. “Our TM500 Multi-UE test solution will allow users to evaluate and optimize the scheduler function within the network and thereby contribute to the success of HSDPA.”
