How does it work? Do I need a cell phone account? How does Cell Sync get
the time from the NIST? Cell Sync contains a specialized receiver and
decoder to convert the cellular signals. A highly accurate one-pulse-per second output
is provided to Cell Sync from the CDMA receiver. This rising edge of
the signal is synchronized to the the start of each CDMA second. How accurate is Cell
time synchronization? What type of hardware do
I need? The only other requirement is a functioning Windows PC with an available serial (COM) port. Do I need an Internet
connection to use CDMA? I already have a CDMA
phone; will Cell Sync work with it? Why would I want to use CDMA for time synchronization? Time syncing using CDMA is a good alternative for remote or highly secured computers. ClockWatch Cell Sync does not require an Internet or modem connection. CDMA time synchronization may potentially be more accurate than syncing over the Internet or by modem. The true accuracy depends on the receiver as well as the computer. Beagle Software's experience is that the Cell Sync when used with the supplied CDMA receiver is consistently accurate within 0.1 second. Can I receive the signal where I am? CDMA receivers should be able to work in most population centers in the US. These very reliable signals are easily received inside buildings. Chances are good that you live and work in an area with CDMA cellular/PCS coverage. If your CDMA phone works where you plan to install Cell Sync, then Cell Sync should have no problem in receiving time signals. Can other computers and devices get their time from Cell Sync? Yes, computers, routers, printers, PBXs and other devices on your LAN can use Cell Sync as a central timeserver. All they need to do run an NTP or SNTP client and point to the computer running Cell Sync. Many computers (including Windows) and networked devices have this capability built in. Will my clock or receiver work outside of the United States? CDMA is used extensively in Australia, China, Korea, Japan and elsewhere. CDMA is currently not widely used in Europe
