DMTS™-3200

Portable CDMA2000 Network Tester

With the same powerful testing features, the Dyaptive DMTS-3200 is the smaller sister product of the DMTS-8000.

• Portable solution for wireless network load simulation
• Generate mixed traffic load using 50 or 100 software-defined test terminals (STT) and 1 or 2 sectors, each sector with up to 11 carriers per sector
• Locate and diagnose load-related problems with detailed logs, statistic and performance analysis tools
• Design tests with a range of voice and data services
• Ideal for smaller scale labs and service trial roll-outs

Key Features & Benefits

• Loads and tests base stations, enabling accurate measurement and analysis of the high correlation between RF load and the combined signaling and user data load
• Highly configurable and upgradeable system ensures simple capacity expansion
• Powerful scripting language and automation features ensure an automatic test environment with reproducible tests that verify all aspects of a network, configuration and performance
• Based on Software Defined Radio technology

Integrated Test Functionality

The DMTS-3200 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 up to 100 STT's or the equivalent of 100,000 BHCA /li> Define tests and load on either a group or individual STT basis Create repeatable and deterministic load
Enhanced Applications
Channel Emulator	Control radio channel impairment to simulate extended (rural) cell and other real-world propagation environments
Base System
Advanced Test Terminal Controller	Define behavior of one or more STTs that allows specific isolated testing that is fully controlled irrespective of what the network is telling the terminal to do
Data Application Simulator	Data Application Simulator Generate data (FTP and HTTP) for mixed voice and data service performance measurement and integrated behavior analysis Correlate behavior across the different layers of all protocols
Performance Analyzer	Analyze performance with a powerful visual data mining tool Enable correlations between logs generated from various levels across all protocol stacks Predict mobile user experience
The DMTS also provides additional options for testing various functions like SMS, MEID, BAM, SDB, WPS, GEC, Access Handoff and many more.

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-3200 provides software-defined Test Terminals (STT) for various voice and data services and user defined RF conditions.  The DMTS-3200 produces an equivalent load of 50 to 100 STTs. It allows users to control and coordinate mobile behavior and RF conditions, as well as define and run tests that are completely repeatable.  Because the system is software based, it is easily upgradeable and reconfigurable, as well as scalable – protecting customers’ investment in their test system.
