Gong, Jiang (author)Frequency translation is required in any modern wireless communication systems.<br/>This is in large part due to the fact that the modulated signal is easy to<br/>transmit in radio frequency in the form of an electromagnetic wave, and the demodulated signal is easy to process in the baseband frequency by a powerful digital processor. Frequency...master thesis 2017

Verburg, Joseph (author), De Winter, Niels (author)During 9 weeks of investigation multiple solutions for implementing a communication module in a supermarket have been explored. These results led to three options which have been further researched. Bluetooth Low Energy (BLE), 433 MHz and ZigBee have been selected as the best communication protocols<br/>for sensor to gateway communication. Chips...bachelor thesis 2017
