WISP - Wireless Instrumented Streaming Platform

WISP is offered in two configurations; the full-size WISP, and the battery powered mini-WISP. Each is a portable, remotely controllable, instrumented wideband RF data capture, transmit, and analysis tool. WISP can also be used as a rapid prototyping platform for advanced software defined radio applications.

Target uses include wireless signal capture, arbitrary signal generation, and frequency translation for both R&D and field-based operations. The units are composed of all-COTS hardware including an embedded single-board computer, large digitized signal storage, wideband software defined transceivers, and a GPS disciplined high stability clock for precision tuning and timing control.

  • Simple, intuitive Graphical User Interface with online help
  • Frequency translation receive and transmit mode
  • Cost-effective, all-COTS, no ITAR restrictions
  • Optional integrated Inertial Navigation Systems (INS)
  • Time-stamped, detailed event log aids post-processing activities
  • Power calibrated for precision knowledge of received signal level and transmit power
WISP Architecture
mini-WISP Architecture


WISP is designed around a very cost-effective combination of hardware and software. Wideband software defined radios (SDR) offer the ability to digitize sustained signal captures in excess of one hour with bandwidths of up to 20MHz (or longer durations with lower signal bandwidths and/or additional hard drive capacity). Files can be stored in a number of user-selectable formats.

WISP can transmit pre-configured or user-defined arbitrary RF signals at power levels of up to 30 Watts. RF signals are specified by baseband digital sample files using industry standard formats. In the transponder mode, signals received at one frequency can be simultaneously retransmitted to another frequency in realtime.

In mobile applications, an integrated Inertial Navigation System (INS) logs high-accuracy position, velocity.

Power Amplifier Module

Power Amplifiers

WISP includes power amplifiers by default, however mini-WISP is offered with or without a power amplifier module.  mini-WISP power amplifier modules (shown above) are designed to be used with mini-WISP and provide accurately power-calibrated output levels controlled from the user interface.  Each module can be custom configured for frequency coverage (up to 6GHz) and power (up to 30 Watts).  A popular version provides up to 5W of power over 500MHz-4200MHz and is powered by either AC or DC (9-36V).

Alternatively, these power amplifier modules may also be used for non-WISP applications and offer an affordable, compact, and nicely packaged amplifier solution for many applications.

Unique Graphical User Interface

WISP provides a very intuitive user interface which runs on an included laptop computer.  The interface takes minutes to learn, can be operated remotely, and offers users a wide variety of flexible and powerful use modes which accommodate a large number of operational scenarios.  The same user interface operates both WISP and mini-WISP systems.
