ABSTRACT: This work aims at analysis of ways of shielding communication under a very new standard for wireless transmission, IEEE 802.11ah. This standard is going to be applied mostly in the rapidly growing area of the Internet of Things (IoT) due to its well designed complex battery saving system and great range of operation. This work also focuses on a theoretical design of a filter working as a frequency selective surface attenuating a very narrow band of frequencies used just under IEEE 802.11ah and passing the other frequency ranges used under the other standards of wireless communication. Shielding of such a communication can be, in certain situations, very important for elimination of the possibility of eavesdropping.
