The main characteristic of GILLAM consists in being aware to any evolution in the sector of data and information transmission and in being continuously in the forefront of developments in these sectors. GILLAM  is active internationally, although its history began less than 50 years ago.

GILLAM was created in 1974 and its activities are mainly focused on networks synchronization and remote control of networks.

In 1985, GILLAM starts its internationalization by taking a major shareholding in the French company SATEL, specialized in emergency power supply for telephone exchanges.

Thanks to all these developments the company GILLAM has become a specialist in telecommunication and remote control, as well as the reliable partner of the most important telecom operators and the distributors of electricity.

Since 1999, GILLAM has developed new activities in the field of time-frequency by implementing high precision clocks for telephony and space technologies.

Since the middle of September 2000, the company is part of the Frequency Electronics Inc group based at Long Island (NY USA) quoted on the Stock Exchange of New York, specialised in the design of High precision clocks (Quartz, Rubidium, Cesium).

In 2003, FEi group acquired Zyfer company specialised in the products of time and frequencies management.

This significant growth induced GILLAM to reinforce through the contribution of financial as well as international partners.

Those different partnerships strengthen the action capacities of GILLAM without taking away its technical and financial mastery. It motivates its operational and commercial developments.
