It is also possible to find timekeeping systems that synchronize over ethernet. These systems transmit wireless internet signals to your clocks. This type of system is best for institutions who need to keep accurate time in multiple facilities. The time settings are transferred over the internet from a central timekeeping server, so clocks across the country can even be synchronized with each other. Imagine how convenient these systems could be for national or international businesses with specific timekeeping needs. If you do not have a stable internet connection, this wireless clock system may not be the best for you.



Another option to consider are CDMA wireless clock systems, or code division multiple access. These clocks keep time by synchronizing from the transmissions of nearby cellphone towers. This method of synchronized timekeeping is perhaps the easiest to install; once it picks up a cellphone signal, the central transmitter will send the time to the clocks synchronized to it. However, there are some drawbacks to this method of timekeeping. First, this is a new, emergent technology and is therefore more expensive than other systems. Also, its ability to keep time is dependent upon healthy cellphone signal. If you are trying to install synchronized clocks in an area with poor coverage, your clocks may not be properly synchronized.



As mentioned, cost is a concern when setting up a large timekeeping network. Most varieties will cost, at minimum, a thousand dollars. The price will vary depending on the strength of the transmitter. High-power clock transmitters will cost several thousands of dollars. Also, when shopping for a wireless timekeeping package, cost of installation may be a factor. The use of these systems, then, is most suited for large institutions who have to keep time accurately in many different areas at once. Personal use of wireless clock systems is generally not practical; the cost of that level of time-keeping precision is certainly steep. People interested in high-power, accurate timekeeping for smaller operations should look instead into atomic clocks, or radio clocks. These are much more affordable; it is even possible to find these available as wristwatches. However, for those with the money and demand, wireless clock transmitters will make timekeeping more accurate and convenient, even up to milliseconds.
