SIM card support

Type of SIM card for which the gadget is designed. SIM cards are required for mobile communication modules, which are mainly found in watch phones and children's beacons (see "Type"). And their types can be:

Micro-SIM. Reduced in size and improved, in comparison with the obsolete mini-SIM, a variety of SIM-cards: the dimensions were reduced to 15x12 mm, while the amount of built-in memory and the overall functionality of the chip were slightly expanded.

Nano-SIM. The newest and smallest variety of replaceable SIM-cards: it has dimensions of only 12x9 mm.

It is worth noting that nowadays, most mobile operators sell SIM cards that are compatible with all three types of slots at once: the chip itself has a nano-SIM format, and such a card can be installed in a micro-SIM or mini-SIM slot using an adapter frame. So paying attention to the type of SIM card makes sense, first of all, if you already have a "sim card" of a strictly defined format and you do not want to change it.

A separate variety is represented by e-SIM(Embedded SIM) — non-removable modules that need to be programmed for a particular mobile operator. On the one hand, this creates some inconvenience: to change the number, changing the SIM card can be easier than reconfiguring the e-SIM. On the other hand, e-SIMs are more compact and...better suited for wearable gadgets, and when you change your number, you do not need to spend money on buying a new card. The compatibility of such a module with the network of a particular operator should be specified separately.

Navigation

This block contains both various navigation systems ( GPS, Galileo) and auxiliary features for them ( aGPS, GPS tracking, maps, compass, altimeter , barometer). More about them:

— GPS module. GPS satellite navigation module built right into the watch/tracker. The initial purpose of such a module is to determine the current geographic coordinates; but how this information will be used depends on the specific type and model of the gadget. For example, in some devices GPS is used only for measuring the distance traveled and/or speed of movement, while more advanced models support full navigation and are equipped with built-in maps. In addition, this feature is almost mandatory in children's beacons (see "Type") — it is GPS that is responsible for determining the location of the child.

— aGPS. An auxiliary feature that allows you to speed up the start of the main GPS receiver. To work for its main purpose, such a receiver must update data on the location of navigation satellites; Obtaining this data in the classical way, directly from the satellites themselves, can take quite a long time (up to several minutes). This is especially true for the so-called "cold start" — when the receiver starts up after a long break in opera...tion, and the data stored in it has become completely outdated. aGPS (Assisted GPS) allows you to receive up-to-date service information from a mobile operator — from the nearest base station (this feature is supported by most operators nowadays). This can greatly speed up the startup process.

— GLONASS. This system is a Russian alternative to the American GPS. However it provides somewhat less accuracy, so GLONASS support is usually provided in addition to the GPS module. Simultaneous use of two systems, in turn, improves positioning accuracy.

— Galileo. European satellite navigation system, created as an alternative to the American GPS. Note that it is under the control of civilian departments, not the military. With a full fleet of 24 active satellites, the system gives an accuracy of up to 1 m in public mode and up to 20 cm with the GHA service. Working in conjunction with GPS, the Galileo system provides a more accurate position measurement, especially in densely populated areas.

— Maps. The feature of displaying topographic maps of the area with heights, relief and types of vegetation on the clock screen. Preinstalled maps are used for visual GPS navigation without being tied to a smartphone. Often, the ability to display maps is implemented in tactical smartwatches with a focus on tourism.

— GPS tracking. Many watches with the possibility of laying routes have the feature of guiding by the GPS track. At the same time, the wearable gadget acts as a navigator around the area, showing the route on the screen and suggesting where it is necessary to turn in one direction or another. Some smartwatches with a pronounced touristic bias also have a “Return Route” programme that allows you to go back along an already traveled route. In GPS tracker mode, trackpoints are usually recorded automatically based on the selected fixing interval. You can also mark a track point manually at any time.

— Compass. A classic compass is a device that indicates the direction to the cardinal points. Wearable gadgets usually use an electronic compass — a miniature magnetic sensor, the data from which, if necessary, are displayed on the display.

— Altimeter. A feature that allows you to determine the current altitude of the user's location. Note that the principle and format of the altimeter may be different. So, some models use barometer data for height measurements, others use information from a GPS sensor; the height itself can be determined relative to sea level, relative to some reference point, or in any of these ways, at the choice of the user. These details should be clarified separately.

— Barometer. A feature that allows you to determine the current atmospheric pressure. One of the applications of the barometer is weather forecasting: for example, a sharp drop in pressure usually signals the approach of bad weather. In addition, information from this sensor can be used to operate the altimeter (see above); and even if the gadget does not have an altimeter, the height difference between two points on the ground can be easily calculated from the pressure difference between them.

Touch screen

The presence of a touch screen in a gadget — like those used in smartphones and tablets. Such a screen provides additional convenience: many features are easier to control with touches and gestures on the display than with buttons and other hardware. On the other hand, the touch screen significantly affects the cost of the device compared to alternatives.

Display type

— TFT. The simplest type of liquid crystal panel used in colour displays. They provide a relatively low, but generally sufficient image quality, while they are much cheaper than more advanced options. This type does not require backlight — more precisely, the backlight is part of the screen itself and turns on with it. Of the unequivocal disadvantages, it is worth noting that many TFT panels have rather limited viewing angles; however, as technology improves, this drawback is gradually eliminated.

— IPS. A variety of LCD panels created in an attempt to eliminate the shortcomings of TFT. There are many subspecies of IPS panels, but they all feature high colour reproduction quality, excellent brightness and wide viewing angles. The disadvantage of this option is the relatively high cost.

OLED. In this case, we mean the technology used to create the simplest monochrome displays. In such screens, each segment that makes up the image is a separate LED, which eliminates the need for external illumination (and even the display itself can be used as a flashlight).

AMOLED. Screens based on a panel of active organic light emitting diodes. Similar to various types of TFT, this technology allows the creation of high-resolution colour displays. Its key feature is that the screen doe...s not require a separate backlight system — in AMOLED panels, each pixel glows independently, resulting in somewhat lower power consumption. At the same time, such screens are distinguished by good colour reproduction quality, excellent brightness and wide viewing angles, however, they are much more expensive than TFT.

Super AMOLED. An enhanced version of the AMOLED technology described above, delivering more expansive colour reproduction and brightness, as well as improved touch accuracy and speed, all at a thinner display and lower power consumption. In addition, the degree of reflection of external light is reduced, such a panel gives less glare and is better visible in sunlight.

— E-Ink (E-Paper). Displays made using "electronic paper" technology; in addition, this category also includes screens such as Memory LCD. The classic E-Ink screen is black and white, does not have a backlight (however, it can be built into particular gadgets), has a very low refresh rate and is poorly suited even for stopwatches, not to mention videos or animated pictures. On the other hand, "electronic paper" is perfectly visible in bright light and has a very low power consumption: it requires electricity only when the image is changed, while a still image remains visible even when the power is completely turned off. Memory LCD screens, in turn, with the same advantages, are almost as good as classic LCD panels in terms of refresh rate, but for a number of reasons they are not widely used.

Transflective. A specific type of LCD panels that can work both due to its own backlight and due to reflected light. In bright external light (for example, in the sun), such a screen effectively reflects it and does not require a separate backlight — however, it is still included in the design and turns on in low light. This type of operation can significantly reduce power consumption compared to traditional LCD screens, where the image is not visible without backlight; in addition, good visibility in bright light is also an important advantage. The main disadvantage of panels of this type is their high cost; in addition, they are made mostly monochrome.

- LTPO. OLED and AMOLED matrices with an adaptive refresh rate that varies over a wide range based on the tasks performed. When rendering dynamic frames, screens with LTPO technology automatically raise the refresh rate to the maximum values, while viewing static images, they automatically reduce it to the minimum. At the heart of the technology is a traditional LTPS substrate with a thin TFT oxide film on top of the TFT base. Dynamic control of the refresh rate is provided by controlling the electron flow. The key benefit of LTPO screens is their reduced power consumption.

Size

The size of the display installed in the gadget; for round screens, respectively, the diameter is indicated.

A larger screen, on the one hand, is more convenient to use, on the other hand, it significantly affects the dimensions of the entire device, which is especially critical for wearable gadgets. Therefore, manufacturers choose the display size in accordance with the purpose and functionality of each specific model — so that there is enough space on the screen and the device itself is not too bulky.

It is also worth mentioning that screens with a similar size may have different aspect ratios. For example, traditional smartwatches are usually equipped with square or round panels, while in fitness trackers, screens are often made elongated in height.

Screen resolution

Screen size in dots (pixels) horizontally and vertically. In general, this is one of the indicators that determine the image quality: the higher the resolution, the clearer and smoother the picture on the screen (with the same size), the less noticeable are the individual dots. On the other hand, an increase in the number of pixels affects the cost of displays, their power consumption and requirements for a hardware platform (more powerful hardware is required, which itself will cost more). In addition, the specifics of using smartwatches is such that there is simply no need to install high-resolution screens in them. Therefore, modern wrist accessories use displays with a relatively low resolution: for example, 320x320 with a size of about 1.6" is considered quite sufficient even for premium watches.

RAM

The amount of random access memory (RAM) installed in the gadget.

This parameter is one of the key ones for the overall performance of the system: the more RAM, the faster the device works, the easier it is to handle tasks with high hardware requirements and the wider the set of applications that the gadget is able to run. Note that a large amount of RAM can compensate for even a relatively weak CPU. At the same time, you need to remember that different operating systems (see above) have different requirements for RAM and features of its use; therefore, only models on the same software platform can be compared by this indicator.

Memory card slot

The presence of a slot for memory cards in the design of the gadget.

Such a slot allows you to expand the total amount of memory by supplementing the built-in storage (see above) with a replaceable card. And in some models, the built-in drive may not be available to the user at all (only basic firmware files are stored there), and the memory card is the only option for user storage.

The advantage of replaceable memory cards over built-in storage is that it is much cheaper in terms of gigabytes of volume; at the same time, cards are issued in different volumes, which allows you to choose the option that is optimal in terms of price and capacity. In addition, removable media can be used to exchange data with another device (smartphone, laptop, etc.) — although that wearable gadgets usually use miniature microSD cards, and devices like laptops use full-sized SD cards. Also note that these same microSD cards are presented on the market in several generations, and the compatibility of watches with a particular card needs to be specified separately.

Device charging

The method of charging the battery provided in the gadget.

MicroUSB. Charging via standard microUSB port. The main advantage of this option is the ability to charge from any microUSB cable or charger with such a connector, not necessarily branded. On the other hand, the connector itself is quite large by the standards of wrist devices and can significantly affect the increase in the dimensions of the gadget.

USB type C. A compact version of the USB interface with a reversible design that allows the plug to be inserted in either direction. The USB type C specification provides for a number of advanced power options - in particular, various fast charging technologies have been developed for this connector.

- Branded connector. Charging via a cable that connects to the watch using the original proprietary interface. The other end of the cable, as a rule, has a standard interface - most often USB, which allows you to use any computer port or network adapter with such a connector for charging. Branded connectors can be smaller than microUSB, and fit better into the layout of the clock. However, for charging, as a rule, you have to use only original accessories, including branded cradles-stands, which are intended mainly for permanent stay in one place.

- Wireless. The main advantage of wireless c...harging technology is the absence of any connectors - which is important, given the miniature size of wrist gadgets. At the same time, this method takes more time and significantly affects the cost of the device. Note that wireless charging is not contactless: the corresponding chargers can take the form of a stand or platform on which you need to put the watch, or a magnet attached to the back cover of the gadget, etc.

- Magnetic. Charging via a cable with convex metal contacts that are magnetized to the connector on the back cover of the wearable gadget. The magnetic contact group has no gaps, which improves the dust and moisture protection qualities of the smartwatch, and the charging plug itself is attracted to the magnetic connector, eliminating the need to look for the correct position for connecting the cable.

- USB A connector. The presence of a built-in connector allows you to connect the gadget directly to the charger, laptop, power bank without using additional cables.
