Bluetooth is the communication tool used by a huge amount of electronics. Learn how the frequency signal is generated and how it's used. In a simple overview of the different versions, we will show how Bluetooth has evolved and been refined. You can also learn something about the specifications and security of this communication standard.

A device that receives a GPS signal to determine and record a location. GPS modules can be found in car and motorcycle navigation systems, cyclocomputers, sporttesters and GPS locators.

LTE (Long Term Evolution) marks the next generation of mobile data networks. This is an intermediate step between 3G and 4G. Although manufacturers and operators sometimes mistakenly refer to it as 4G, it is not a full 4G network. That's for LTE Advanced. The maximum theoretical data transfer rate is up to 175Mbps for download and up to 57.6Mbps for sending data in one frequency band.

Najnovší konektor štandardu USB nesie označenie typ-C. Na rozdiel od predchádzajúcich má odlišný tvar, vďaka ktorému ho možno zasúvať obojstranne, avšak na úkor spätnej kompatibility s portami USB 2.0 alebo USB 3.0/3.1. Rýchlosť prenosu dát dosahuje až 10 Gbit/s. Novým rozšírením je potom štandard USB 3.2 Gen 2×2, ktorý dvojnásobne navyšuje prenosovú rýchlosť, a to až na 20 Gbit/s.

A digital compass (magnetic sensor) detects the earth's magnetic field to determine the cardinal points. This enables the phone to correctly rotate the map to fit your orientation.

The motion of a gyroscope rotates in space on all three axes. In this case, it determines the direction in which you are moving your phone.

An ambient light sensor that monitors the ambient light levels and dynamically adjusts the display backlight intensity. A practical and handy feature, it is part of most modern phones. It turns the display brightness to the maximum in bright sunlight and dims the backlight in the dark.

The vast majority of modern mobile phones are equipped with a proximity sensor. Its task is to evaluate the distance of an object from the sensor. Once the object gets close, the telephone activates a particular function. One of the most common is the function to turn off the screen and the touch layer when the user dials a phone number and places the phone close to his ear.

Accelerometers and G-Sensors are motion sensors that determine the tilt in space. The phone uses it to know which way it is being held, e.g. portrait, landscape or upside down.

Android je operačný systém vyvíjaný spoločnosťou Google, ktorý v súčasnosti používa väčšina výrobcov mobilných telefónov. Ide o tzv. otvorený operačný systém a má prakticky neobmedzené možnosti prispôsobenia. Niektoré úpravy je možné vykonať pomocou základných nastavení, zatiaľ čo ďalšie modifikácie si môžete kedykoľvek stiahnuť z obchodu Google Play. Používateľ tak môže veľmi jednoducho upravovať nielen grafické rozhranie, ale aj spôsob ovládania telefónu. Slabšou stránkou systému Android je jeho vyššia náchylnosť na napadnutie škodlivým softvérom. Podrobnejšie sa popisu jednotlivých OS, ich výhod a nevýhod venujem v článku Porovnanie mobilných operačných systémov.
