DMTS™-9200

LTE System Tester

For wireless network equipment vendors and network operators, the Dyaptive DMTS-9200 is a platform for the future-proof test strategy for LTE radio access networks. 

Equipment manufactures face many challenges associated with bringing LTE products to the market. In developing and optimizing the physical layer, or testing the implementation of the protocol, design and verification teams need tools that provide both the flexibility of UE logging and analysis, and the ability to generate load and stress that tests the boundaries of their implementation.

The Dyaptive DMTS-9200 offers flexible, high-capacity solutions to LTE testing challenges.

• Expandable:
• The only LTE solution that provides hundreds of simultaneously active UEs per cell within a single platform
• Up to 800 simultaneous VoIP sessions
• Up to 32 2x2 MIMO sectors
• Flexible:
• Control message flow and content with RRC protocol editor leveraging our multi-UE implementation of PHY MAC and RLC
• Flexible framework provides ability to script tests using our Layer 1 and 2 implementation to test signalling and timing performance
• Control UE capabilities, bands and operating revisions to more precisely model real-world scenarios
• Reconfigurable:
• Use a common hardware platform for HSDPA, HSUPA and LTE
• Insightful:
• Understand access network performance from UEs perspective, with logging across multiple layers of the protocol
• Predictable:
• Leverage an automated test environment that provides repeatable and deterministic tests

Key Features & Benefits

• Hundreds of UEs engaged in coordinated or random traffic scenarios simultaneously
• Verification of messaging at multiple layers of the protocol
• Inter RAT handover from LTE to HSDPA or HSUPA
• 2 x 2 MIMO
• Support for 1.4MHz, 3MHz, 5MHz, 10MHz, 20MHz
• Up to 100Mbps transfer rates

Software Defined Radio (SDR)

As with our 1xRTT, EvDO and UMTS systems, the DMTS-9200 employs a unique application of SDR technology. The DMTS-9200 system produces an enormous offered UE capacity and 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-9200 can be deployed in multiple configurations. It can scale from a single blade processing element supporting ten STTs, and one MIMO sector (one sector-carrier) up to 80 blade processing elements supporting hundreds of STTs, for up to 32 eNodeB sector ports.
