WiMedia Explorer 300
Analyzer and Generator for WiMedia Ultrawideband, Wireless USB and Bluetooth

WiMedia Explorer 300


The WiMedia Explorer 300 is the world's first over-the-air MB-OFDM protocol test system for WiMedia Alliance's Ultrawideband common radio platform, Wireless USB protocol and Bluetooth®.

Designed to evolve with specification updates, the Ellisys WiMedia Explorer 300 will help you solve current and future WiMedia, Wireless USB and Bluetooth challenges. Improving your time-to-market has never been so easy!


The Ellisys WiMedia Explorer 300 Analyzer is ideal for peripheral development, protocol stacks verification, communication optimization, and other intricate development tasks. Its high-quality UWB RF front-end records traffic exchanged over the air between devices so you can display the resulting decoded information in your choice of several convenient formats.

The Ellisys WiMedia Explorer 300 Generator is the world's first frame generator for WiMedia Ultrawideband and Wireless USB protocols. It helps verify product and component reliability by generating reproducible traffic, timing and error scenarios.

Containing a specialized processor designed specifically for WiMedia-based and Wireless USB protocols, the WiMedia Explorer 300 Generator produces sequences of arbitrary frames with programmable inter-frame delay, and can then wait for any kind of response frame or event. The processor's instruction set enables you to emulate various WiMedia equipments. Integrated with Ellisys' leading Ultrawideband and Wireless USB protocol analysis software, you can reproduce previously-recorded scenarios, or modify them for testing corner cases and recovery mechanisms.

Based on the same proven hardware as the Ellisys WiMedia Explorer 300 Analyzer, the WiMedia Explorer 300 Generator provides a powerful new test methodology to maximize the quality of your protocol implementation and surpass your Ultrawideband R&D challenges.

The Generator also includes the Ellisys WiMedia Precompliance Test Solution, which automatically executes a comprehensive set of test scripts that implements the entire suite of test scenarios defined in the new WiMedia Platform Test Specification version 1.2. The test solution interacts with a device under test, captures all traffic exchanged with the device to a file, analyzes the traffic to verify compliance behavior, and generates a compliance report. Any detected issues can then be easily debugged using the capture file and the included WiMedia protocol analysis software. More »

The Ellisys WiMedia Explorer 300 Duo is a flexible bundle of two full-featured units that can be used as one analyzer and one generator, two analyzers or two generators depending on your testing requirements. More convenient than having both functions on the same unit, this allows you to better share your test equipment among your R&D team.

Typical Analysis Setup

The figure below shows the simple setup used with the WiMedia Explorer 300 Analyzer to easily analyze the behavior of a WiMedia network. The analyzer is placed between wireless devices and records all traffic exchanged over the air. Analyzed data is then transmitted in real time for display on the Analysis Computer. This is the preferred method of assessing a device's wireless behavior.

Ellisys WiMedia Explorer 300 Generator

Generator Applications

  • Emulate most WiMedia equipment, including Wireless USB hosts and devices
  • Test error recovery mechanisms by generating frames with incorrect content or timing
  • Functional validation and stress testing of protocol stacks

Generator Features

  • Generates arbitrary frames with full control of the frame raw data down to the PHY layer
  • Generates sequences of frames with programmable inter-frame delay
  • Uses exported scripts from protocol analysis software to play back error scenarios

Wireless USB Host Emulation
The figure below shows a typical setup for emulating a Wireless USB host. A generator script is exported from a trace previously recorded by the Ellisys WiMedia Explorer 300 Analyzer and can be modified to include errors. You can also create a script from scratch for total control. The data generator will execute the specified scenario, and the Device Under Test will react as if the original host was transmitting the data. This setup is very useful for testing corner cases and error recovery behavior of the Device Under Test.

Host Emulator Setup

Wireless USB Device Emulation
The figure below shows a typical setup for emulating a Wireless USB device. A Wireless USB device transmits frames at a precise time defined by the host, and provides the requested data. Ellisys' WiMedia specialized processor contains specific instructions to wait for Device Transmit and Device Notification Time Slots. The generator executes the script, and the Host Under Test receives data as if a real device was answering its requests. This setup is useful for testing protocol stacks and helping in host driver development.

Device Emulator Setup


Ellisys Ultrawideband Script Edition Software helps you create, edit and debug scripts in a convenient manner. Traces previously recorded by an Ellisys WiMedia Explorer 300 Analyzer can be exported to a script and played back by the generator. You will then be able to quickly understand and fix the issue.
