Bartley Machine solves critical communications issues in VHF, UHF, 800 MHz and 900 MHz frequency bands

AMESBURY, Mass., Jan. 12, 05 — Interference issues for wireless users have reached crisis levels, resulting in critical miscommunications for everyone from utility companies to first responders. Recently, Bartley Machine & Manufacturing, Co., Inc., announced the release of a new line of active band-pass filters known as the “Ultra-Q Filter,” which solves these critical communications issues. As more and more people utilize wireless communications, the available spectrum becomes increasingly clogged with traffic, creating interference on adjacent channels, with the end result being the inability to send and receive critical information.

“The Ultra-Q is designed to completely eliminate all adjacent channel RF interference within specified VHF, UHF, 800 MHz and 900 MHz frequency bands,” said Paul Bartley, CEO of Bartley Machine. “The Ultra-Q effectively blocks all interfering frequencies without affecting the carrier frequency, resulting in a reduced number of dropped calls and an increase in signal range and quality.” The software-driven Ultra-Q can be programmed in the field using a laptop, thereby eliminating the need for an RF technician to program the filter.

The patent was formally owned by AeroComm, Inc., of Englewood Cliffs, NJ, which ceased operations a year ago, and Bartley purchased the technology from their successors. “We knew of this filter and its capabilities, and recognized that the technology was just too good to let go undeveloped. The wireless industry is in desperate need of a filter that can do what the Ultra-Q does, and we wanted to ensure the availability of this filter to the industry.”

The Ultra-Q is currently deployed in systems throughout the country, including tunnels in New York City and Boston, in several airports and in-building systems, and is used by numerous utility companies to prevent interruption of data transmission in SCADA systems.
