DuraTime 2.4GHz Wireless Clock System

The DuraTime Wireless Clock System provides highly reliable synchronised time, without expensive wiring. Communication between wireless clocks, master clock and other wireless clocks is frequency hopping, spread spectrum radio technology to send time updates to all clocks. This easy to install system is designed for zero system downtime with no single point of failure.

DuraTime Wireless Clock Technology

DuraTime clocks use the IEEE 802.15.4 standard and operate on the 2.4GHz spectrum using channels 25 & 26. These channels are used for technical and scientific uses which mean that they don't overlap with normal Wi-Fi communications. The risk of interference with other systems is further reduced as the data packets used by DuraTime wireless clocks are small and non-streaming. DuraTime wireless clocks are designed not to interfere with properly operating Wi-Fi products.

The use of multi-path communications means that clocks do not rely on being within range of a central master clock. The wireless mesh network architecture means every wireless clock is both receiver and transmitter allowing them to relay the time to other wireless clocks. This is true of analogue and digital wireless clocks.

The Clock System Designed Not to Fail

The DuraTime Wireless Master Clock has two separate master clocks mounted together in a rack mounting compatible assembly. Two master clocks support redundant master clock operation. The master clock has an OCXO crystal oscillator that provides time accuracy to 1 second over 20 years. NTP synchronisation is standard and Wireless GPS is optional. This combined with the multi-path communication designates a system designed not to fail and time you can rely on.
