DMTS™-9000

UMTS Network Tester

The Dyaptive DMTS-9000 is designed to provide increased test coverage and capacity for UMTS wireless network operators and network equipment vendors. 

• Generate real-world load profiles of mixed voice and data traffic in UMTS environments
• Load networks with up to 1000 software-defined test terminals (STT) per rack, and up to 64 sectors, or up to a total of 80 sector carriers with support for 3 carriers per sector, to increase test coverage, test base stations and other network equipment to full capacity
• Locate and diagnose load-related problems with detailed logs, statistic and performance analysis tools
• Schedule and automate testing to increase test capacity
• Roll out UTRAN products and services faster

Key Features & Benefits

• Highly scalable, configurable and upgradeable system ensures simple capacity expansion
• Based on Software-defined Radio Technology
• Tests are repeatable, deterministic and behave predictably
• Spend time testing instead of configuring equipment or building internal tools
• Reduce test cycle time through improved efficiency and automation
• High terminal density in reduced footprint

Integrated Test Functionality

The DMTS-9000 integrates functionality from multiple test devices to generate realistic, deterministic and repeatable load. It is comprised of a base system and applications that can be added:

Bulk Call Generator	Generate a load using a variety of call models and traffic types, with hundreds of STTs and the equivalent of 100,000 BHCA Define tests and load on either a group or individual test terminal basis Create repeatable and deterministic load Mix of terminal and traffic types, traffic content, call arrival and duration models Create handover scenarios (soft, softer, hard)
Enhanced Applications
Channel Emulator	Control radio channel impairment
Base System
Data Application Simulator	Data Application Simulator Generate data (FTP, HTTP, Email (POP3/SMTP), UDP) for mixed voice and data service performance measurement and integrated behavior analysis Correlate behavior across the different layers of all protocols Set custom Quality of Service (QoS) configurations
Performance Analyzer	Analyze performance with a powerful visual data mining tool Enable correlations between logs generated from various levels across all protocol stacks Provides mobile user perspective

Software Defined Radio (SDR)

The DMTS system employs a unique application of SDR technology to effectively put a city in your lab. Using SDR, the DMTS provides software-defined test terminals (STT), including RF conditions and a variety of voice and data traffic.  The DMTS-9000 system allows users to control and coordinate mobile behavior and RF conditions, as well as define and run tests that are completly repeatable.  Because the system is software based, it is easily upgradeable and reconfigurable, as well as scalable – protecting customers’ investment in their test system.

Configurations

The DMTS-9000 can be deployed in multiple configurations. It can scale from an introductory system supporting saturation of each sector-carrier (cell) up to 120 STTs and connectivity to 64 base station sectors simultaneously. The DMTS-9000 may support up to 3 carrier frequencies per sector using a single Dyaptive transceiver port.
