Spectracom offers a 900 MHz wireless clock system for organizations with time-sensitive
operations. The system is compatible with Spectracom GPS network time servers as a
master clock for traceability to UTC (Coordinated Universal Time). Legally Traceable
Time™ from the time server is broadcast by a wireless transmitter, synchronizing the
displays to all other network systems and devices throughout the facility.
This innovative system offers an easy, cost-effective solution by providing accurate,
synchronized time displays without expensive, disruptive installation procedures. Because
there are no wiring requirements, install times are drastically reduced, and it is ideal for
renovation projects – no need to worry about asbestos issues or messy, in-wall electrical
installation work – as well as new construction.
The system uses a rack-mount network-based transmitter with a remote antenna that works
much like an IEEE-802.11 wireless router. It receives its time from a network time server
via NTP over a network (or from RS-485 from via a twisted pair). It transmits a time
signal every minute. Once an analog or digital display clock receives and synchronizes
to the signal, it becomes a transmitter, creating a robust and efcient wireless mesh
network. Such a system provides signicant advantages by improving signal strength and
coverage as more clocks are added. The sync signal is transmitted every minute from
externally-powered clock and every two hours in normal mode (5 year life) or every four
hours in economy mode (8 year life) from battery powered analog clocks.
The system is easily scalable as additional needs develop in the future. In applications
across a large campus, two types of repeaters can be used to maintain the signal. One
type receives and amplies a wireless signal from a clock or main transmitter. Another
receives a specially-coded sync signal through the network from the main transmitter.
New features include greater clock sensitivity for longer transmission range, enhanced
clock diagnostics, and network-manageable transmitter. All new system components are
backwards compatible with previous generations.
