RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted. The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. When working in challenging environments, you want a smartphone that can keep up with you. The CAT S53 is a rugged smartphone you can rely on, as it is sand, water and dust proof. Moreover, it is more than just splashproof as it can handle full submersion in water of up to 1.5 metres for 30 minutes. Weatherproof: rain, snow, sand, dust and dirt proof. Passed more than 50 seriously tough durability tests, including hundreds of tumbles, full submersions, multiple drop tests on each side and corner, and many more

Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width READING, UK, July 19, 2022 – Bullitt Group, the global licensee for Cat® phones, today adds two new 5G devices to its range, with the unveiling of the next generation Cat S53 Smartphone and its first mobile hotspot, the rugged Cat Q10, now available. Meanwhile the Cat Q10 is a 5G mobile internet hotspot that provides reliable and fast connectivity for multiple devices, particularly outdoors thanks to its robust, weatherproof design.W-CDMA (Wideband Code Division Multiple Access) is an air interface used by 3G mobile networks. It is one of the three different UMTS interfaces together with the TD-SCDMA and the TD-CDMA. The standard provides faster data transfer speeds and allows more users to connect to the network simultaneously.

stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 2G cellular network. With its 6.5" HD+ super-bright display optimized for outdoor visibility, you can view crips and clear images even on sunny days. It even works when your hands are wet or wearing gloves.

The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology

System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 3G mobile network. One of the main characteristics of the display is its type/technology, on which depends its performance.

Személyre szabott hirdetések Ezeknek a sütiknek köszönhetően mi és partnereink az Ön vásárlásai, viselkedése és preferenciái alapján releváns és személyre szabott termékeket és szolgáltatásokat tudunk Önnek felkínálni. With the CAT S53, the manufacturer also brings 5G connectivity to one of its outdoor phones for the first time. Quite a lot of frequencies are available for the currently fastest mobile standard and also for 4G, so you can surf the mobile Internet with the smartphone even when traveling. The mobile reception proves to be good during our random tests in the test period, but not quite on the level of high-end smartphones.

Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. CapacityA CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel. Közönségmérés Ezek a sütik lehetővé teszik számunkra, hogy optimalizáljuk oldalunkat az Ön kényelme érdekében az Ön használatának módja alapján. A cél az, hogy emlékezzünk vagy előre jelezhessük a választásaikat. Ide tartozik például a funkciók használata, elhelyezkedése, viselkedése az oldalon. A sütik feldolgozásának elfogadásával nélkülözhetetlen és analitikai sütik kerülnek telepítésre eszközére, amelyeket a weboldal megtekintéséhez használ (az "Értem" gombra kattintva mindkét kategóriát elfogadja, vagy kiválaszthhatja a kategóriák közül csak az egyiket a "Beállítások" gombra kattintva). A technikai sütiket mindig telepítjük az eszközére, az Ön beleegyezése nélkül is, mert ezek nélkül a weboldalunk nem működne. Information about additional software and hardware features of the rear camera which improve its overall performance. With up to 45.1 °C on the front, the CAT S53 can already get quite warm at room temperature under load. It could also become uncomfortable to hold the phone on hot days. However, this does not affect the performance: 99.1% of the initial frame rate is still achieved at the end of the 3DMark stress test.
