Frequency Electronics Inc., Mitchel Field, Long Island NY

Founded in 1962 as a research and development company, FEI's goal from inception has been to provide the most advanced control of frequency and time — the essential factor for communication and data transfer in electronic spacecraft systems, in telecommunications networks, and in certain military applications. In short, if the electronic signals transmitted in any of these systems are not synchronized, accurate communication is impossible. FEI's products ensure that the "call goes through."

In the mid-1990s, the Company transformed itself from a defense contract manufacturer into a high-tech provider of precision time and frequency products used to synchronize voice, data and video transmissions in wireless communications systems. These systems are found in both ground-based stations and on-board commercial satellites. The Company also continues to support the United States government with products for defense or space applications but it will do so with more emphasis on COTS (commercial off-the-shelf) products than on contract-based projects.

FEI's US Headquarters is located in Mitchel Field, Long Island NY. The company operates in a modern, 100,000 square foot facility where it performs all US engineering, development, production and administrative functions.
