FSK supplies a wide variety of Radio Frequency (RF) and GSM (Global Systems for Mobile Communication) based technology, providing secured wireless communication between monitored sites and responding control centres. FSK’s advanced transmission technology consists of reliable communication systems which are used for signal transfer and response. Data signals are transmitted simultaneously via multiple mediums including: GSM (Global System for Mobile Communication); Radio Frequency (RF); and Internet Protocols (IP). The dual transmission of mediums ensure complete signal integrity, giving security/monitoring companies and alarm/network users complete peace of mind.

Historically FSK products were designed specifically for use in the security industry, but innovations into GSM and IP technologies, expanded product ranges beyond our niche market, allowing for many more monitoring applications which include: individual; equipment; and environmental monitoring.

What is FSK?

FSK is an abbreviation for a process known as ‘Frequency Shift Keying’. FSK may also be referred to as frequency shift modulation or frequency shift signalling. ‘Frequency Shift Keying’ is the process in which data signals are converted into specific frequencies or tones in order to transmit signals over wire, cable, optical fibre, or wireless media, to a destination point.

The history of FSK processes dates back to the early 1900s, when this technique was discovered and then used to work alongside tele-printers in the transmission of messages by radio (RTTY). Presently FSK, with some modifications, is still effective in the digital world, where it is used in conjunction with computers and certain modems. The FSK Group is proud to be associated with the term ‘FSK’, as it marks our history and illustrates our evolution, growth, and innovation through technology.
