Earlier in this presentation three different frequency bands were mentioned for the Chronos: 433, 868 and 915 MHz. Each frequency is allocated in a certain frequency based on the regional restrictions for the frequency. Typically the 433 MHz bands are used in Japan, India and in most parts of the world, 868 MHz is very commonly used in Europe and 915 MHz is used in North and South America. Does this mean that a user who is located in Europe is required to purchase the 868 MHz version? Not necessarily. It would depend on the application and region in which the application is suited for. Currently, the 433, 868 and 915MHz versions are available now. The watch hardware is identical for these two watches. To go from 868 to 915 MHz all that is required is to download a different piece of software. The RF access point, on the other hand, is very similar, but it has one component different. The 868 MHz version has an extra zero ohm resistor on the antenna to give it a longer antenna size. To convert this to the 915 MHz, the resistor would just have to be removed and vise versa to convert from 915 MHz to 868 MHz. The antenna for the Chronos is actually the metal frame of the watch itself. There is no PCB trace or chip antenna, the assembled Chronos is used as the antenna.
