The guide is designed to address geographic regulations covering the standard ISM FSK band frequencies; 315MHz, 434MHz, 868MHz, and 915MHz and to address the approximate range-versus-bandwidth to given antenna pairs. For further information on the devices used in this publication, see the following datasheets: IA4420 Universal ISM Band Transceiver datasheet: IA4420-DS 2 TABLE OF CONTENTS About this Guide........................................................................................................................................................................................ 2 Introduction............................................................................................................................................................................................... 5 DESCRIPTION.........................................................................................................................................................................................5 1.
