Used in watches, but there are many problems to consider in actual operation.

1: Is the navigation map in the watch downloaded in advance or in real time? It takes a lot of space to download in advance, and the storage space of general telephone watches is not very large.

2. The battery life of the watch is known to be high in navigation power consumption, and the battery of the watch will not be as big as that of the mobile phone.

3. The screen display navigation is a factual picture, and there are so many screens on the mobile phone watch. If you put it there, the navigation is either the wrong way or a traffic accident. When we saw it clearly, we had already passed this intersection.

4. With a mobile phone, won't mobile navigation be better than a watch?

To sum up, some fans will say that the above questions are not difficult. You can make the storage bigger, the battery life stronger and the screen bigger. Then it's better to use a tablet to navigate, which will solve the problem. This is why the original intention of designing a telephone watch is to make it convenient for our consumers to use, fast, compact and easy to carry. Of course, it's just a personal opinion, for reference only, and you are welcome to leave a message with better suggestions.

Hello, I'm a diode. I think there are several reasons:

1. Watch screen is too small.

The largest dial of a watch on the market is about 46mm, so it is difficult to display a map on such a small screen.

2. Weak signal reception

At present, the watch can't leave the mobile phone completely. Even if some watches support e-sim function or use mobile phone network to update information, they can't update the position information in real time, which leads to the information lag, which is the biggest problem in navigation.

3. The watch software needs to be improved.

At present, some Android watches and Apple watches support software download, but the adapted software has limited functions, which is not as convenient and comprehensive as mobile phone software.

At present, there are many smart watches that can realize navigation, so it is not difficult for smart watches to realize navigation technically, but the following problems need to be overcome: map system: compatible with indoor and outdoor maps, after all, you need to carry out navigation and positioning systems both indoors and outdoors; it may be a little difficult to design based on common indoor and outdoor positioning technologies, and the navigation system is relatively difficult to implement: navigation system based on indoor and outdoor maps and positioning technologies. Our hummingbird view has always believed that the first step of indoor and outdoor navigation is indoor and outdoor map+high-precision positioning technology. At present, smart watches have the following problems: generally, smart watches have small battery capacity and short battery life. If it is used for user navigation, it may often face the problem of rushing for more than one day or running out of electricity at any time, and the service life of the watch will be greatly shortened. Practical problem: At present, smart watches are basically used for children at home to contact and make phone calls; Or as a sports bracelet, as a navigation tool, the current demand is relatively small, and the development intention is not very high. The bracelet can link to the mobile network, but its stability is not very high due to memory or real-time update. Map updating: If it is an embedded map system, the map needs to be updated one after another; It is not very convenient if it is a real-time update and consumes a lot of network resources.

Each smart watch has its own design. Many smart watches on the market have different prices, one is brand, the other is function, and the third is material.

The basic functions of common smart watches include time, steps, heart rate, sleep and so on. Many companies will design some specific functions according to users, such as Bluetooth music, barometer thermometer, altitude, navigation and so on.

As for why some companies don't support navigation.

First, the watch needs to be equipped with an additional navigation module, which consumes a lot of power for the watch, and the battery capacity of the smart watch itself is also small.

Second, smart phones are always around, and now there are many satellite navigation systems supported by smart phones. GPS in the United States, Beidou in China, Galileo in Europe and GLONASS in Russia all use mobile phone maps with high accuracy.

The third is the positioning of smart watches (users). Some people are busy with work and need long battery life, heart rate detection and sedentary reminder. Some people like sports and need exercise tests and psychological tests. Some people like to travel and climb mountains, and need navigation, air pressure, temperature and so on. It's all about people.

Hello, I'm Xiao Fei's brother who sells mobile phones. I'm glad to answer this question for you.

Each smart watch is different in design, price, function and quality. Smart watches that can navigate must have a GPS module, and they can design navigation functions, and the price is relatively high.

Some smart watches are designed purely for watching time, making phone calls and pedometers. They have no navigation function and are relatively cheap.

Looking at the configuration and price of watches, those who support navigation must have network link and processing performance, and the price is higher than those who do not support navigation.
