Agilent Technologies Inc. has introduced new 7.2 Mbps IP data connection and Inter-RAT voice and data handoff enhancements to its 8960 Wireless Communications Test Set running UMTS Lab Applications.
These enhancements build on the 8960 Lab Application's value of providing a broad, cost-effective benchtop solution for meeting a wide variety of User Equipment (UE) design needs, including functional test and RF measurements for device validation, integration and regression testing.
As the first one-box tester to couple a 7.2 Mbps HSDPA IP data connection with real-time 3GPP network emulation, including Inter-RAT voice and data handovers, the 8960 provides engineers with a tool they can use early in the design cycle to ensure UE design integrity throughout the cycle of test and deployment.
Agilent's new 7.2 Mbps IP data connection provides an innovative solution for stressing new high data-rate applications to ensure UE design will meet stringent network conditions, thereby ensuring high customer reliability. Because the 7.2 Mbps IP data connection supports 7.2 Mbps RF and IP data, engineers can stress the UE at rates above what is traditionally seen in real networks.
In addition, they can test the impact of high data rates on UE hardware components, which impact battery life and current drain, evaluate software issues such as memory overruns and buffer limitations, as well as analyse RF parametric performance of the UE transmitter and receiver.
Two-cell emulation, an advanced feature of the E6701E/T and E6703D/T Lab Applications, ensures realistic testing of UMTS Inter-RAT handovers and cell selections by allowing the mobile to select from, and hand over between, two independent cells.
The Inter-RAT voice and data handoff enhancements allow engineers to functionally test UE voice call quality and data intensive applications while roaming between GSM and W-CDMA/HSDPA networks. Voice handovers are supported, as are network-initiated and autonomous handovers during an IP data connection.
Using two-cell emulation, an engineer can make measurements such as throughput, packet statistics, ACK/NACK and protocol messaging analysis, on the transmitted and received data between a GSM and HSDPA network now up to 7.2 Mbps. In addition to testing the functional aspects of the handover, it is also possible to ascertain whether the handover occurs at the correct parametric conditions and that the data application is correctly managed throughout the transition.
According to Agilent, nowadays designers require cost-effective measurement solutions capable of providing broad test coverage for stress test, validation and regression testing across RF, protocol and software. With its new enhancements, Agilent's E6701E/T and E6703D/T Lab Applications are now equipped with the leading-edge test capabilities necessary to meet this need. As a result, engineers have the benchtop tools they need to effectively verify today's multi-format wireless device designs.
The Agilent E6701E GSM/GPRS Lab Application, E6703D W-CDMA/HSDPA Lab Application and their associated E6701T/E6703T Special High Data Rate Lab Applications work with Agilent's 8960 Wireless Communications Test Set to create a cost-effective desktop network in a box with RF measurement performance to meet the wide variety of UE design needs in today's UE design environment.
