Research of wifi systems protection efficiency

Abstract

This thesis investigates 3G, 4G, LTE and Wi-Fi IEEE 802.11 network standards in terms of their performance, security, and cost. Moreover, an analysis of the security and vulnerability of these technologies are provided. From the analysis it can be concluded that Wi-Fi is today an inexpensive technology with high bandwidth, low direct and associated costs, and low power consumption compared to 3G, 4G, LTE and WiMax. Wi-Fi (802.11 a/b/g/n) is – due to its cost- performance ratio – an appropriate wireless technology to provide Internet services to cafes, hotspots and public places.
