Edwards wireless clock solutions comprise a reliable master/slave cascading network that synchronizes clocks from a central on-site master controller. The master clock receives highly accurate time signals from an NTP or GPS source and relays timecodes to local slave clocks via wireless signals. Each receiving slave clock acts as a signal repeater, transmitting the timecode instantly to nearby clocks, which do the same. This ripple effect occurs in mere microseconds, but has the ability to synchronize more than 60,000 clocks installed throughout highrises, sprawling facilities, and small buildings alike. Because the signal fans out and is repeated by a cascading num-ber of devices, a single clock will typically receive its data from a number of different angles. This dramatically reduces the effect of obstructions, noise sources, or long distances on the reliability of the system. Furthermore, if an individual clock looses its signal, it will link to a nearby clock and automatically synchronize with that new source. The cascading network also reduces system setup and installation costs, thanks to the relatively low signal strength that is necessary for it to function efficiently. This eliminates the expense and time required to obtain an FCC license.
