The two types of watches contain many same points. Both can be called 4G smartwatches, for they both support LTE networks and support some normal functions, such as dialing, alarm, camera, etc. At the same time, they also have their own merits and respective functions.
◑ GPS+WIFI+LBS location function
Both watches support location functions, helping the parents monitor their kids' position. Three different location modes help to keep track of your kids in any situation. GPS, the most accurate locate mode, locates your kids with error range from 5 meters to 15 meters. However, only in the open GPS can it work well. If your kids are somewhere the GPS signal is weak, the watch will locate your kids with LBS or WIFI. As long as the watch can scan the surrounding WIFI signal, whether the WIFI is encrypted or not, it can keep track of your kids with a location error range from about 20 meters to 50 meters. The last locate mode is LBS locate, and its location error is more than 100 meters. The LBS will be the last choice if the watch can't locate the kids with GPS and WIFI.
◑ SOS calling
With the Setracker application, parents can set at most three SOS numbers in the watch. When the kids press the button for over 3 seconds, the watch will automatically dial those numbers one by one for two times until the phone is picked up. This function can help kids contact their guardians quickly when they are in emergency circumstances.
◑ Pedometer
Not only is it a watch, but also a pedometer. Both two kinds of watch can record the number of steps your children walk in a day to reflect whether the amount of exercise is up to the standard. Parents can open or close this function through the Setracker application.
◑ Other functions
Not only chatting functions, but the two watches also support multiple security functions that can monitor the kids to protect them from being safe. With the Setracker application, parents can contact kids by dialing the phone number or just sending the text through the Chat function. Parents can monitor their kids' position by checking the GPS location and setting a range as a safety zone, and their phones will receive an SMS if their kids go out of the safe zone. Parents can set undisturbed time through the application, and the watch will lock the home screen during the period to avoid kids playing it in a class.◑ Power consumption
KT 26 watch and CAT1 watch both contain 680 mAh batteries; KT26 can standby for 70 hours while CAT1 can standby for 340 hours. The power consumption of the CAT1 device during the idle state is 10 times less than the power consumption of CAT4; that's the reason that the standby time varies too much.
◑ Data rate
The data rate is the biggest difference between the CAT1 device and the CAT4 device, and so is the watch. Our KT26 watch belongs to the CAT4 device, theoretically supporting uplink data rates up to 50Mbps and downlink data rates up to 150Mbps. On the other hand, our CAT1 watch supports uplink data rates up to 5Mbps and downlink data rates up to 10Mbps. The different data rates determine the differences in their cost and some functions. To support a higher data rate, KT 26 watch possesses higher-level hardware along with a higher cost.
◑ Hardware and operating system
Memory and processor, the hardware we're going to compare between the two kinds of watches, are the two most severe parts of a watch chip, which takes on the function of computing and storage. As we know, the quality of the processor determines the running speed of a device. The greater the processor, the faster the device processes and calculates the data. Our KT26 watch runs on a 1.2GHz dual-core processor (Cortex®-A7), while the CAT1 watch runs on a 500MHz one-core processor (Cortex®-A5). The performance of KT26 in data calculating and information processing is much better than the performance of the CAT1 watch. Although the processor determines the running speed, it is also influenced by the Random access memory, known as RAM. Our KT26 watch's RAM is 4GB, while CAT1's RAM is 128M. The capability of saving the data of the KT26 and CAT1 watch is also different. The watch can save more pictures, music, or files when it comes to a bigger ROM. KT26 watch contains 512M space to store the file, and the dates KT26 can store are 4 times the ones CAT1 can store. Because of the different hardware, the two watches contain two different operating systems. KT26 smartwatch is an Android operating system, and the CAT1 watch is RTOS operating system.
◑ Software
Except for the aforementioned functions that the two watches both support, KT26 also supports playing music and video. Parents can download many children's songs, stories, and videos to help kids develop potential and acquire knowledge. KT26 has some small but practical features that the CAT1 doesn't have. KT26 can check the call history, and just like the phone, the call history shows the call status, time, and duration of the call. And KT26 is also a stopwatch for its can time. It also has voice recording and calculator functions, which are two common functions during daily life. Those functions are all the native functions of the KT26 watch, but if parents want to install other applications on the watch, it can come true. KT26 supports downloading many kinds of software, such as Whatsapp. Whatsapp, one of the most famous chat freeware that Facebook owns, supplies instant messaging and voice-over-IP service. It's very convenient for children who prefer to communicate through Whatsapp. Moreover, there are still many other functions waiting for you to explore.
