DMTS™-8200

1xEV-DO Network Tester

With the DMTS-8200, network operators and equipment vendors can rapidly accelerate network stability testing and performance optimization.

• Test and measure performance before rolling out new services on high speed 1xEV-DO digital wireless networks 
• Load base stations with a reproducible mix of various data traffic patterns
• Quantify and predict the impact that different data services may have on existing services
• Load networks with up to 1000 software-defined test terminals (STT) per rack, with support up to 48 sectors in a full system, or up to a total of 80 sector-carriers with support for 11 carriers per sector, to increase test coverage, test base stations and other network equipment to full capacity
• Schedule and automate testing to increase test capacity

Key Features and Benefits

• Highly scalable, configurable and upgradeable system ensures simple capacity expansion
• Based on Software Defined Radio technology
• Tests are repeatable, deterministic and behave predictable
• Spend time testing instead of configuring equipment & building internal tools
• Intuitive graphical user interface for system configuration and test design and management
• Top-to-bottom traffic analysis of QoS sensitive applications such as Push-To-Talk, VoIP and VideoTelephony

Integrated Test Functionality

The DMTS-8200 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:

Base System
Data Application Simulator	Generate a traffic load using a variety of data models and traffic types, with up to 1000 Test Terminals or the equivalent of 1 million access attempts per hour Define tests and load on either a group or individual Test Terminal basis Create repeatable and deterministic load Generate traffic (FTP, HTTP, PTT) for data service performance measurement and integrated behavior analysis Correlate behavior across the different layers of all protocols Set Quality of Service over-rides Create up to four unique flow configurations
Enhanced Applications
Channel Emulator	Control radio channel impairment to simulate extended (rural) cell and other real-world propagation environments
Performance Analyzer	Analyze performance with a powerful visual data mining tool Enable correlations between logs generated from various levels across all protocol stacks Practical mobile user experience

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), for various data services and user defined RF conditions.  The DMTS-8200 system produces an equivalent load of up to 1000 STTs that generates 1 million calls per hour (BHCA). 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.

Configurations

The DMTS-8200 can be deployed in multiple configurations. It can scale from a single blade processing element supporting 100 STTs and 1 sector (1 sector-carrier) up to 80 blade processing elements supporting 100 STTs, 48 sectors with 11 carriers per sector and can process calls simultaneously for up to 80 carriers.
