Poraba energije mobilnih terminalov pri uporabi brezžičnih tehnologij

MARKOVIĆ, ANDREJ (author), Kos, Andrej (mentor)

Glavni cilj diplomskega dela je predstavitev brezžičnih tehnologij, njihovega delovanja ter porabe energije. Večji del vsebine se nanaša na tehnologijo LTE, WiFi, Bluetooth ter 3G. Namen je bralcu čim enostavnejše prikazati metodologijo tehnologij in razumeti porabo energije ter jo primerno predstaviti. Za enostavnejše razumevanje celotne vsebin, se diplomsko delo začne s kratkim pregledom zgodovine. Nato so tehnologije nazorno razložene (GSM, UMTS, WiFi, LTE, BLE) in kronološko opisane, vse do primerjav porabe energije med posameznimi tehnologijami. Glavna primerjava je med tehnologijama 2G in 3G, med 3G, WiFi ter LTE, katera je plod Univerze iz Danske in na koncu še podrobna analiza BLE signala ter njegove porabe pri uporabi BLE iskalca ključev. Sam sem izvedel meritev ter izračunal pričakovano življenjsko dobo baterije BLE iskalca ključev v neprekinjenem delovanju.

Abstract

This diploma thesis focuses on wireless mobile technology, its functioning and energy consumption. Mainly it refers to technologies as LTE, WiFi, Bluetooth as well as 3G. Purpose of it is to present the reader as simply as possible methodology of technologies and their energy consuption in a way it could be easily understood. For easier understanding this diploma starts with short overview of the history, leading to more depth review of each technology (GSM, UMTS, WiFi, LTE, BLE). Technologies are described chronologicaly and there are given examples of their energy consuption for each of them. Main comparison is given betwen technologies 2G and 3G, WiFi and LTE, which was made by University of Denmark. At the end there is a detailed analysis of BLE signal and its use at BLE key searcher. I myself have measured and calculated life expectancy of BLE's key searcher battery at its continuous operation with no interruptions.
