Testing of E911 Services

Parsippany, NJ, June 8, 2004 – Noise Com announced the E911 Noise and Interference Generator, which provides an expandable, easy-to-use platform for testing the susceptibility to interference of E911 applications on cellular phones, as well as GPS receivers used in airborne, automotive, defense and mobile locations.

The instrument is based on Noise Com’s leading digital noise, arbitrary waveform and proprietary switching technology, which enable an industry-leading On/Off ratio of 164.5dB. This translates to an order of magnitude improvement compared to competitive instruments, enabling the E911 to solve the major challenges facing GPS product test engineers. Using the E911, low phase noise, high power out-of-band interference can be generated without obscuring signals in the GPS band, thereby isolating the GPS receiver from their effects. Out-of-band interference signals of Noise Com’s E911 tunes from 800 MHz to 2500 MHz.  This is substantially easier, faster and more cost-effective than alternative approaches, allowing engineers to emulate interference coming from cellular, PCS, 3G, Bluetooth, and WLAN frequencies.

“With the E911, we are addressing the many security issues facing the world today,” said Kent Wardley, Vice President of New Business Development. “Customers can use the same instrument to support a wide range of existing and emerging standard requirements to provide interference resistant location services.”

Off-the-shelf Platform Generates full range of user-defined jamming waveforms.

The E911 Noise and Interference Generator is equipped with one or optionally two independent arbitrary waveform generators capable of 40MHz bandwidth for interference generation over the L1 and L2 or L5 bands. The instrument features an integrated PC that allows user-defined arbitrary interference and jamming waveforms. Any waveform can be generated, including sine waves and noise, which can be pulsed at any duty cycle between 0 and 100% at 6.67 nanoseconds resolution. The two-channel, modular design enhances expandability, allowing engineers to simultaneously test GPS receiver operation in L1 and L2 or L5 frequencies. As a result, the instrument effectively tests products based on today’s standards and also provides an easy route to supporting emerging requirements.

The E911 provides an off-the-shelf platform integrating all of the necessary flexibility including up to two 800 MHz to 2500 MHz synthesizers, power amplifiers, Gaussian noise source and a power meter.  The Gaussian noise source provides a fixed low-level reference, which is used to calibrate the output power of the arbitrary waveform. The internal power meter ensures accurate measurements, assists in calibration and sets high output power levels up to +21 dBm after the built-in GPS signal and interference combiners. This off-the-shelf approach is a substantial improvement over alternative solutions, which generally require a signal generator and separate electronics for signal amplification and combining.

Noise Com’s new generator supports three modes of operation: Continuous Wave (CW) Synthesized, Arbitrary Interference including Broadband Gaussian Noise and Pulse Mode for Burst and TDMA emulations. The E911 is easy to use, featuring access tables of pre-stored GPS testing parameters as well as optimal color display functionality.
